1914] The Bee Genus Celioxys. 155 
Ceelioxys banksi n. sp. 
Female. Length about 11 mm. Black, femora black, the rest of 
the legs ferruginous with the middle of the tibize obscured with blackish 
and the tarsi dark toward apices; face above antenne very coarsely 
punctured, the clypeus medially triangularly produced and somewhat 
reflexed; mesoscutum amd scutellum very coarsely punctured, the 
punctures well separated on the disk; lateral teeth of scutellum rather 
short, pointed; scutellum gently rounded posteriorly; middle of face 
with appressed long white pubescence, clypeus with similar short 
pubescence; suture between mesoscutum and scutellum with a line of 
appressed white pubescence, a spot of similar hair at the posterior end 
of tegulze; mesopleurze with the anterior and posterior margins densely 
clothed with similar pubescence, as is the region immediately in front 
of and below tegule; the punctures of mesoscutum each with a long 
white delicate hair; tegule dark, obscurely reddish on disk and outer 
margin; wings dusky, with the apical margins more densely infuscated; 
dorsal and ventral segments 1-5 with apical bands of appressed white 
pubescence; first abdominal segment rather coarsely and sparsely 
punctured, the second and third with transverse impressions, basad of 
them the punctures about a puncture width apart, apicad of them the 
punctures slightly larger, laterad about as dense as basad of impressions 
but medially very sparse; fourth dorsal segment punctured about as 
third, with a transverse impression which is interrupted medially; fifth 
segment with the punctures finer, basally less than a puncture width 
apart, apically the punctures more than their own width apart; last 
dorsal segment with a median carina, the punctures close, the apical 
production of the last segment almost as long as the basal part of the 
segment; apex of last dorsal segment basad of notch of last ventral 
segment by about one and one-half times the length of the distance from 
notch to apex of segment; ventral segments 1-5 coarsely, closely punc- 
tured, punctures on fifth segment decreasing in size apicad; last ventral 
long, narrow, the apical portion bent downward, the sides near apex 
with a distinct notch. 
Type-locality: Falls Church, Virginia. 
One specimen, collected August 20, from the collection of 
Mr. Nathan Banks, after whom the species is named. 
Lype—Specimen:* Cat. No..18221, U.S. N. M. 
The peculiar form of the clypeus easily distinguishes this 
species. In this table if this character be omitted the species 
would run to couplet no. 33, but the two species in that couplet 
both have the legs entirely black as well as the clypeus differ- 
ently formed, etc.
