THE CANADIAN KNTOMOLOGIST. 369 



is a relatively gigantic representative of the group o( A. zizice, personata 

 and pacifica. Among the Colorado species it has a strong superficial 

 resemblance to A. topazana CklL, but is easily separated by the black 

 hair of face and pleura, and the absence of long pale hair on the basal 

 segments of the abdomen, the latter, in the female, being as dark and bare 

 as that of A. carlini. There is another rather similar species which 

 Viereck has named in manuscript. Three females and two males were 

 taken. I have not seen the European A. cyanescens Nyl., but from the 

 description it seems to be a related species. 



Andrena Wheeler i Qx^m.c}^&x. — i $. I have compared this minutely 

 with a specimen from Dr. Grjenicher, and cannot see any difference. My 

 specimen has collected a quantity of bright orange pollen, which can 

 hardly come from the Umbelliferse, on which, in Wisconsin, A. Wheeleri 

 is oligotropic. A female A. Wheeleri, from Waldoboro, Maine, from Mr. 

 Lovell, was collected at flowers of Sediim acre. 



Aiidrena phocata, n. sp. 



$ . — Length about 8 mm,, black, with a dull white pubescence, long 

 on head and thorax ; head and cheeks normal ; process of labrum broadly 

 truncate ; clypeus convex, very shiny, with well-separated punctures and a 

 median mouth-band ; anntennae dark, third joint about as long as the 

 next two combined ; vertex and front dull and granular ; distance from 

 lateral oceHi to occipital margin hardly equal to diameter of ocellus ; 

 facial fovese bicoloured, seal-brown above, white below, occupying rather 

 more than half space between eye and antenna, little separated from eye, 

 going a short distance below level of antennte ; mesothorax rather shiny, 

 microscopically tessellate, sparsely, minutely punctured ; scutellum shining, 

 sparsely punctured ; area of metathorax dull and roughened, not defined ; 

 legs black, with pale hair, that on hind tibite and tarsi tinged with yellow- 

 ish ; spurs pale ; tegulas rufopiceous ; wings strongly reddish, stigma and 

 nervures ferruginous ; abdomen shining sericeous, impunctate j segments 

 2 to 4 with thin bands of long white heir, that on 2 broadly, and on 3 

 narrowly interrupted ; apical fimbria shining pale yellowish ; second 

 segment depressed hardly one-third, but deeply. 



Hab. — Steamboat Springs, Colorado, May 27, i $ . Exceedingly 

 like A. fragiliforinis Ckll., but separated by the smoother area of meta- 

 thorax, and the shining, more sparsely punctured clypeus and mesothorax. 

 The bicoloured facial fovea is also distinctive. It is also allied to A. 

 runcinatce Ckll., but much smaller, with differently-coloured caudal 

 fimbria, etc.
