elytra finer and more closely placed, the vestiture, especially 

 in fresh specimens, much denser, nearly concealing the punc- 

 tuation of the elytra, and the markings always more con- 

 fused. This species seems to be confined more to the northern 

 parts of our continent, all the specimens I have seen came from 

 Canada, Michigan, Wisconsin and Minnesota. The punctures 

 at the base of the elytra in A. obsoletus Oliv. are larger and more 

 sparsely placed, the vestiture not dense, showing the punc- 

 tuation very plainly, the markings are always better defined. 

 Of both species I have seen about forty specimens and found 

 the characters mentioned very constant ; even in a few very 

 small males of obsoletus the obliquely pointed apices of the elytra 

 are very prominent and show no sign of becoming rounded.

Andrena fulvipennis Sm. 



Process of labrum divided into two small shining tubercles, mandibles 

 broad. Thorax almost uniformly roughened. 



9. — Length 9 mm. Front striate, occiput very finely sculptured, dull, 

 clypeus with distinct punctures irregularly but somewhat closely arranged, 

 the longitudinal median impunctate area almost obsolete, noticeable more 

 by the slight elevation of the clypeus along the middle. The third joint 

 of antennae almost as long as joints four, five and six. Pubescence of 

 head short and close, pale ochreous, frontal foveae with a pale brown 

 sericeous lining. Dorsulum finely sculptured, with short, stifif black hairs 

 arising from the poorly defined punctures, central line and parapsidal 

 grooves faintly impressed on anterior half of the mesonotum. The lateral 

 smooth lines prominent, shining, the surface around them also more shining 

 than that of the rest of the dorsulum. The pleurae around the tubercles 

 with a rich ochreous pubescence, on the inferior half the hairs are more 

 like those on the head. Sculpture of scutellum much like that of dorsu- 

 lum, postscutellum with a fringe of pale ochreous hairs. Metathorax dull, 

 the surface distinctly roughened, enclosure not defined, floccus of meta- 

 pleurae pale, strongly developed. Wings fuscous, uniformly clouded, 

 nervures almost black, stigma pale brown, second recurrent nervure re- 

 ceived by the second submarginal cell at or a little before the middle. 

 Abdomen uniformly dull, microscopically granular. Fringe on first dorsal 

 segment almost obsolete, that on second, third and fourth segments thick, 

 very distinct, ochreous. Anal fimbria abundant, dull brown. Pubescence 

 of femora pale, that of tibiae and tarsi brownish to fuscous. Black. Tibial 

 spurs whitish, tarsal claws brownish.
