SOME ILLINOIS BEES.* 

 Charles Kobertson. 

 Andrena hirticeps Sm. 



Andrena hirticeps Smith, Brit. Mus. Cat. Hyni. 1 : 116. tf. 1853. 



§. — Black; pubescence black, except on thorax above, on 

 vertex and usually about insertion of antennae, where it is 

 ochraceous ; clypeus shining, coarsely punctured, except a 

 median raised line; process of labrum semicircular; third 

 joint of antennae about equaling next two joints together, 

 fiagellum dull testaceous beneath ; wings fusco-hyaline, apical 

 margins clouded; nervures and stigma fusco-ferruginous, 

 second submarginal cell about as long as third to second recur- 

 rent nervure ; abdomen shining, almost impunctate except on 

 bases of segments, no pubescent fasciae. Length 12-13 mm. 



Carlinville, Illinois; 24 5, 27 $ specimens, the sexes taken 

 in copula. I have regarded the male as that of A. vieina, 

 and the female as only a variant form. The true A. vieina, 

 I think, does not occur here. The male, which, no doubt, 

 resembles the above, I think will be found to want the black 

 hairs on the head. But for the description of the male, I 

 would say that A. errans is the same as A. hirticeps. 



Andrena viciniformis n. sp. 



o.. Black; head, thorax and femora clothed with fulvous 



pubescence which, is brightest on scutellum, palest beneath, 

 a few blackish hairs about ocelli and on clypeus, floccus pale, 

 tibiae and tarsi with blackish pubescence, the scopae on hind 

 femora and tibiae, however, pale beneath; clypeus shining, 

 coarsely punctured, a median raised line impunctate ; process 

 of labrum semicircular ; third joint of antennae about equal- 

 ing next two together ; wings fusco-hyaline, nervures fusco- 

 ferruginous, second and third submarginal cells subequal ;
