364 Mr. T. D. A. Cockerell— Descriptions and 
segment with a very large, projecting, median apical tuft of 
white hair ; ; the lateral pieces of the genitalia (stipites) 
appear as broad, black, convex, highly polished plates, ante- 
riorly beset with long spreading hairs, but the apical tufts of 
hair are long and convergent, meeting in the middle line. 
Quetta, India, July 1902 (Nurse). 
Resembles C. hyleiformis, Ev., but is easily separated by 
the much more finely punctured abdomen and the longer 
stigma. 
Colletes brevitectus, sp. n. 
3 .—Leneth about 9 mm., anterior wing 5°8 mm. 
Black, with apex of clypeus, mandibles, and labrum (which 
has strong longitudinal keels) ferruginous; flagellum dusky 
reddish beneath ; legs reddish brown, the tarsi paler ; sides 
of first abdominal segment ventrally red ; hair of head and 
thorax dense and white, tinged with creamy on upper part of 
face and on thoracic dorsum ; ; hair of thorax above very short 
and dense, short-plumose, and moss-like (as in C. carinatus, 
Rads., and C. aberrans, Ckll.) ; malar space nearly twice as 
broad as long; fourth antennal joint distinctly longer than 
third, fifth conspicuously longer than fourth ; mesothorax and 
scutellum so hidden by hair that the sculpture cannot be seen ; 
metathorax very hairy. Legs with white hair, dense on hind 
tibize in front; tegule pale testaceous. Wings clear, stigma 
dusky red, nervures fuscous. Abdomen dullish, densely and 
rather finely punctured, so as to appear rugose ; five broad 
white felt-like hair-bands, and white hair also at extreme 
base of second segment ; fifth ventral with no long median 
tutt. 
Quetta, India, August 1902 (Bur sé). 
Related to C. carinatus, Rads., but smaller, with no very 
strong contrast between the punctures of the first and second 
abdominal segments. 
Celioays polycentris taurus (Nurse). 
Col. Nurse gave me five males, which he took at Quetta in 
June 1903. One of these has been labelled C. polycentris, 
Foerst., by Friese, and Nurse accepts the reference. It 
happens, however, that the specimen seen by Friese has the 
upper apical teeth of abdomen represented by two short 
denticles on each side, as is usual in polycentris; but the 
other specimens show that the usual condition in taurus is 
that of a stout superior tooth on each side, the second one 
being wholly absent or represented by a shght rudiment.
