Hab. New Holland ; Van Diemen's Land. Obs. This species very closely resembles the H. leucozonius of Kirby, but differs in the sculpture of the metathorax, and also in having the second submarginal cell broader. From an examina- tion of a large number of this apparently abundant species, it is found to vary in the grooving of the enclosed space at the base of the metathorax, the grooving not being always smooth or equally deeply sculptured ; the abdominal fasciae are frequently nearly obsolete, in others broader, sometimes narrower ; thus in its varieties resembling those of the H. leucozonius.

HYMENOPTERA. 131 This insect would be taken for a species of the genus Andrena without attentive examination, so closely does it resemble the insects belonging to that genus, but it" is easily distinguished from them.

PTILOTHRIX. Ptilothrix, F. Smith's MSS. (Details, Plate VI.) Head not quite as wide as the thorax, ocelli placed in a slight curve on the vertex ; the labium twice the length of the mentum, broadest about the middle, tapering towards the apex, which is blunt ; the paraglossae half the length of the labium, attenuating to a point at their apex ; the labial palpi rather shorter than the labium, four-jointed, the first and second elongate, placed end to end, the two apical joints minute, placed at the side of the second joint at its apex; the maxillary palpi six-jointed, the three basal joints of equal length, the three apical ones of equal length, but shorter than the basal joints ; the anterior wing having one marginal and three submarginal cells, the marginal cell slightly rounded at its apex ; the second submarginal cell 132 HYMENOPTERA. much narrowed towards the marginal, the third slightly so ; the posterior tibiae and the basal joint of the tarsi furnished with a thin scopa of long pubescence. 1. PTILOTHRIX PLUMATUS. Female. Length 5 lines. Black, the clypeus and labrum have large scattered punctures and are thinly clothed with griseous pubescence, above the insertion of the antennae and on the cheeks it is dense, short, and dark fuscous ; the flagellum ferruginous beneath, tips of the mandibles yellow. Thorax, the disk densely clothed with short fulvous pubescence, thinner and paler on the sides ; the legs red, the coxae black ; the anterior coxae and femora fringed with black pubescence ; the interme- diate and posterior coxae and trochanters fringed with cinereous pubescence ; on the anterior tibiae and tarsi above, and on the posterior tarsi within, it is fuscous, otherwise the legs have a glit- tering pale yellowish pubescence, having a little which is snow- white at the apex of the posterior tibiae ; wings hyaline, and having a yellowish tinge towards their base, tegulaa and nervures pale rufo-testaceous. Abdomen ovate, the base fringed with short fulvous pubescence ; the margin of the first and three fol- lowing segments has a broad fascia of very short decumbent pubescence, broadest in the centre ; the two apical segments covered with rigid black pubescence. Obs. This beautiful species is remarkable for having the entire pubescence plumose, each individual hair being pectinate ; that on the metathorax, viewed under a pocket lens of good power, resembles fine down ; even the short pubescence which forms the fascia on the abdomen is equally beautiful.

This species very closely resembles the Osmia c&rules- cens ; the female is difficult to distinguish ; it differs in being larger and of a brighter blue, and in wanting the smooth, shining space below the post-scutellum always present in 0. ccerulescens. The male differs in the form and pale colour of the antennae beneath, and in the margin of the apical segment being deeply notched in the middle and entire laterally. Hab. Nova Scotia; U. States.
