ANDRENA CYANOPHILA Cockerell. 



Florissant, Colorado. July 5, 1907. At flowers of Argentina 

 anserina. (S. A. Kohwer.) 



Female. — Length, 9J mm. Black, with pale ochreous pubescence, 

 becoming white beneath. Facial quadrangle a little broader than 

 long. Process of labrum narrowly truncate. Clypeus shining, 

 coarsely and confluently punctured, with a smooth median line. 

 Facial foveae seen from above white, rather broad, below going below 

 level of antennae. Flagellum dark reddish beneath. Third antennal 

 joint about as long as next two combined. Mesothorax and scutellum 

 shining, with extremely large punctures. Area of metathorax with 

 sharp irregular ridges. Tegulea dark reddish. Wings dusky hyaline. 

 Stigma and nervures dark reddish. Basal nervure meeting trans- 

 verse median. Second submarginal receiving first recurrent nervure 

 beyond the middle. Hair on hind tibiae white, on inner side of 

 hind tarsi light orange. Abdomen shining, the nondepressed por- 

 tions closely punctured, second segment in middle depressed almost 

 three-fourths. Imperfectly developed hair bands at sides of second 

 and following segments. Hair at apex light ochreous. 



This species is close to A. Mppotes, but distinct. 



ANDRENA CYANOPHILA, variety. 



Fort Collins, Colorado. June 22, 1899. (Gillette.) 

 Female.— Length, 9 \ mm. Black, including the legs. Pubescence 

 grayish white with a slight ochreous tinge. Facial quadrangle about 

 as broad as long. Process of labrum truncate. Clypeus shining, 

 strongly and closely punctured, with a strong median raised line. 

 Facial foveae seen from above snow white, occupying about half the 

 space between eye and antenna; below narrower, reaching about to 

 level of top of clypeus, separated from eye by a narrow shining band. 

 Flagellum stained with bright chestnut red beneath. Third antennal 

 joint hardly as long as the next two combined. Mesothorax and 

 scutellum shining, with large and deep irregularly placed punctures. 

 Metathorax entirely dull, swollen at sides, the area well defined, 

 with very strong irregular wrinkles and sharply cut off behind by a 

 slender transverse ridge. Tegulae reddish, wings reddish hyaline, 

 stigma and nervures dark rufofuscous. Basal nervure meeting 

 transverse median. Second submarginal cell receiving first recurrent 

 nervure well beyond the middle, hair on outer side of hind tibiae 

 white, on inner side of hind tarsi pale reddish. Abdomen shining, 

 very distinctly but rather finely punctured. Second segment de- 

 pressed in middle more than two-thirds; rudimentary white hair 

 bands at sides of segments 2-5. Apical hair light golden. 



(This was given as a distinct species, but I believe it to be con- 

 specific with cyanopliila.) 



b n . Hind tibiae and tarsi red. 



a 12 . Mesopleura granular ; mesothorax with small punctures.
