beyond the middle, aervulus interstitial and forming an acute angle 

 with the first abscissa of the discoidal vein; propodeum with a poorly 

 defined funnel-shaped enclosure, sides i>t' the propodeum similarly 

 sculptured with the enclosure though more rugulose and in addition 

 indefinitely punctured; abdomen dullish black, finely reticulated and 

 indistinctly punctured, the tergum from the base of the depressed 

 margin of the second tergite to the end of the fourth tergite more 

 shining than elsewhere but nevertheless finely reticulated, depressed 

 portion of the second tergite down the middle : elevated portion :: 

 7 : 16, second, third and fourth tergites with most of their depressed 

 portion covered with a whitish fascia, erect pubescence of tergum 

 also whitish, that of the first and second tergite rather conspicuous, 

 fifth tergite punctured, no definite sculpture between the puncture-, 

 find iria dark brown, pygidium, planate, rounded at apex, conical 

 in outline, dark reddish brown to blackish, and with a slightly 

 submarginally impressed line on each side. 



Andrena (Andrena) pulverea new species. 



Type. — No. 4,0-43. The Academy of Natural Sciences of Phila- 

 delphia. 



Type Locality. — California (no further data). 



Related to A. (A.) papagorum Viereck and Cockerell. 



Female. — Length 9 mm.; body black, mostly covered with pale 

 ochreous or whitish hairs; head with its facial line : transfacial 

 line :: 52 : 65, axial line : temporal line :: 28 : 17, malar line : joint 

 3 of antennae :: 2 : 9, ocelloccipital line : greatest diameter of 

 lateral ocellus :: 3 : 4, elevated portion of malar space nearly wanting, 

 head covered with whitish hairs, front rather indistinctly, longi- 

 tudinally striate, not elevated into a welt along the fovea, its crista 

 poorly developed, fovea at most : ocellocular line :: 10 : 13, foveal 

 band wanting, distance between fovea and ocelli : ocellocular line 

 :: 4 : 13, fovea slightly attenuated below its middle where it is 

 apparently only a little narrower than the greatest width of the fovea, 

 the latter continued to a point well below 7 the antennal line, upper 

 half of fovea filled with pale -eabbrown hairs, lower half with still 

 paler hairs vertex and temples along the upper edge of tin 1 eye with 

 dark hairs, face shining, finely reticulate, with distinct puncture- 

 that are as many as one to three puncture widths apart, clypeus 

 distinctly elevated above the apical margin, slightly convex, dullish. 

 sculptured like the face except that the punctures are seemingly 

 -mailer and the reticulation denser, clypearea present but poorly 

 denned and represented by a narrow impunctate area, clypeus
