A lover of Nature, who applies himself toany special departm^t m his own locality, may collect specimens, but they wfll afford butt very Uttle satisfaction unless named and arranged ; to which end he must have a good system, and must have characters of the received genera «d known species. i;o that he 6m ascerUun the historyjf thj phject he finds, if k^wn; and if he is so fortunate as to meet with any- thing new. may have the means of knowing it to be so. that he may communicate his observations upon it without feAr of merely repeat- ing what others have done, and perhaps creating useless nam«J. which encumber the science hewishes to advance. To a beginner u^ the study of Nature, nothing can be more discouraging than to hijve to search out every object in.the most extensive general works (provided he is so fortunate as to havk accessto them) because there is asyet- no i^ttempt at a list of the productions of his countryj where the limited number would .facilitate hU investigations. ^ Those who contribute local catalogues in any department of Natural History, render important assistance: but something more is re- quired. It has occurred to ihe that the. publication in this Journal of fragmentary portions of a provisional Fauna Canadensis might contribute not a Uttle both tu assist the cultivators pf ZoologiMl Science and to accumulate useful materials for future kbourers who / may be enabled to attempt what would now be premature,-a general/ mtematic work on Canadian Zoology. By a provisional Fauna, wj' mean a systematic arrangement with the essential chaincters of aU Buch genera and' species as have either, to our knowledge. actuaUy been foutid in Canada, or are deemed very likely to be found there- being known as inhabiUnts either of the' more northern or the im- medfately southern regions. In this^ way, without pretending to be 'vet iii a condition to offer any reliable account of all the Imng crea- lures inhabiting our country, we may afford useful assistonce to those who are disposed to examine them, and by their labours thus assisted our conjectural list will gradually change into an authenticated record of observed facts. -Many, who without such aid could do nothmg, or would remain insulated collectors, unable to determine whether what thev obtained was known or unknown, scarce or familiar, would be at ouM enabled, ^th a great increase to their own enjoyment from the N MATBRIALS FOR A FAUNA CANADKN81S. / I Itn jy of Nature, to become c<|»ntribaton to scientific knowledge ;— to •Mist in determining the range of species, and to call attention to hitherto undescribed forms. There may be branches of Natnral History in which the advances already madcj^ well as the extent and general interest of the sub- jects, would warrant the publication of volumes specially dedicated to "y their illustration. I have already announced my desire, restrained only by necessary considerations of prudence, of publishing, from ma- terials now in my hands, a Blora Canadetuit, the utility of which I think' cannot be doubtful ; .though no one can be more conscious than , I am how much remains to be done in the way of diligent herborisa* tion throughout all parts of the Proirince, and it is in promoting this interesting labour, that I t&ink the work I propose would be especially* useful. The birds which annually visit us are beginning to be well known. We have public and private museums of considerable rich- ness. A French-Canadian gentleman— M. Lemaire — has published • in his own language, a good popular account of them, which has met with well-deserved success ;. and we know that he has proposed to our highly-valued friend, T. W. Cottle, Esq., of Woodstock,— whom no- body excels in a familiar practical acquaintance with the birds of Canada, — to translate his work into English, witji such modifications as his own judgment might suggest; thus producing an Ornitholo- gical manual for Cadadians using the English language, which could not fail of giving a great impulse to this attractive branch/of Zobtogy. Even our own means, from the extensive collection of the University, aided by local catalogues and occasional notices, would enable us to do much in relation to the birds of Canada, and we may possibly at- tempt a sketch of their arrangement ; but for particulars respecting species, their distinctions, and their habits, we should gladly come as leamera t6 such an authority as we have named, end we earnestly hope that he will be indvkced to engage in the undertaking we have referred to. We could easily name a friend who possesses admirable materials- for working out several of the more difficult orders of Cana- ' "dian Insecta ; and there are not wanting considerable materials for < the illustration of the land and fresh-water Mollusca. How far iji;,,, may seem'>«»pi^ientJj^,grpo^,witb ihese ^apero w^ ; but the following 'fragm%tti, relating to Neuropterous Insects will at least shew^what we propose, ai^d what ipeans are at our disposal for working out our plan. % The great class Itueeta, includes urjdculate animali with jointed '^'l / 4 MATBllIALS rOR A FAUNA CANADENSIS. JnMulatat m well as the lower form Rotifera. . Thns defined, the dasi includes a lower sub-clasS termed Myriapoda, with limbs to each ar^ ticulatio'n, and whose deyelopraent is not much beyond that of the larval forms of the higher division ; together with the true, or Hexth podout itueetOt haVing the (ower apneudages developed^ on three arti- culations only, and the upper, aSBim||ing the form of "wings, if at all, on two wticulations only. The Aptjrout examples will probably ap- pear more certainly the more their structure is understood to be degraded forms of some of the other divisions. It is at least certain that the different groups of Jpterotu insects differ more from each other than they do from Some of what are considered as h^her forms, whilst there are various special instances of the absence of wings in species obviously allied to others which are furnished with them ; so that on the whole, th^ distinction of winged and wingless insects is of tittle value, and the ^teroui orders commonly received might pro- bably be appended to others of which they are but less devdoped examples. The degree of importance really belongingfto some other . of the characters relied upon in classifying insects, is very doubtful. One much employed is the mandibulate or suctorial character of the oral apparatus, yet it has been proved that the same elements occur in both structures, and the transitions from pne to the other are most remarkable. We cannot think that either the abortive hind wings of the Diptera; or their more completely suctorial mouth, should prevent the recognition of their close affinity with Hymmoptera^ and yf^lm dine to the opinioii that these two orders, the most peculiarly typical of all insects, would, combined together^ occupy a central position in a natural distribution, around which thp other leading forms might be placed in the order of their tetidendes of development : 1. I^europ- tera; 2. Lepidoptera; 8. CoUopUra} 4. Orthoptera ; 6. Hemiptera, Confining our attention now to the Newroptera^ it seems to us, in the first place, abundantly evident that the Caddis-flies, which have been elevated into a distinct order under the name oi Trichoptvrat only exhibit a modification of the Neuropttir^m structure in analogy with LepUopiera. Reviewing, then, the various sections which have been Sroposed, we are inclined to the following view of the famiUes of* leuroptera. We place first Libellulieht the Dragon-flies, as exhibit- ing the greatest power and ferocity ; 2. Fhrygmeiaot the Caddis-flies ; 8. TermtHiat the White Ants, distinguished by their social habits and their large consumption of food, obtained without violence ; 4. Pmtcr- limbs ; a distinct head, with two antennae { respiration by tracheae ; and distinct sexes. It is obvious that these characters exclude, on the one hand, Jrachmdaj on the other, all grades of Cnutacea and / \ .Jir: i-V MATKftlALS rOR A FAVI^ CANADfeNSIS. ^5 mdb, the Planipennes of^authoM, including several well-marked sub- families ; and, 5. ^phemtvida, May-flies, in some respects having the low^ organisation in the order, yet approaching the Libdlulida ii\ their imperfect metamorphosis, as well as in the character of their antennae. We now proceed to give a synopsis of Canadian' Neulroptera. "Die following table will distinguish the families : .. , • Obdib NumoPTnA : Wings four, ' yearly equal, membranous, uiaallv , . reticulate, rarbljauppressea; mouth more or less eompletelj mandibu- late; nez^r properlj suctorial ; larva bexopod^Jv^r '^tcnnae.
