Milwaukee, Wi.s., 3 I and 13 9 specimens, taken on the 

 flowers of Tcenidia (^Zizia) integerrima and Thaspium trifoli- 

 atum aureum, from June 8 to June 18, 1903. This is undoubt-

American ants. 



Andrena persimilis n. sp. 



9. — Length about 9 mm. Black, with dirty white pubescence on head 

 and thorax, and grayish-white hair-bands on the abdomen. Facial fovese 

 moderately broad, covered with light pubescence. Clypeus shining, with 

 small and close punctures, and a narrow impunctate median line. Process 

 of labrum truncate. Cheeks considerably swollen, shining, thinly pu- 

 bescent. Flagellum rufo-testaceous beneath near the apex. Pubescence 

 of thorax long and thin, partly concealing the surface. Disc of meso- 

 notum and scutellum highly polished, with very minute punctures; meta- 

 thoracic enclosure defined by impressed lines. Its surface, as also that 

 of the surrounding parts, dull and rather smooth. Legs dark brown, 

 with white hairs, those on the inner surface of the basal joints of hind 

 tarsi yellowish. Tibial scopa dense, plumose. Wings clear white, with 

 dark nervures. Tegulae and stigma testaceous, the latter less than half 

 as wide as the marginal cell. Third submarginal cell shorter than the 

 first, but nearly three times as broad as the second, which is hardly nar- 

 rowed above, and receives the first recurrent nervure behind the middle. 

 Abdomen shining, flattened, broad and oval, without punctures. Con- 

 tinuous broad hair-bands of white appressed pubescence on segments 2 

 to 4. Anal fimbria dirty-white, with a reddish tint. 



Milwaukee, Wis., one female, taken August 24, 1903, col- 

 lecting pollen on the flowers of Solidago canadensis. The 

 structure of the tibial scopa places this species in the genus 

 Pterandreiia Rob. In many respects it answers the description 

 of A. distans Prov., but differs as follows: wings distinctly 

 clear, stigma pale testaceous, not ferruginous, second submar- 

 ginal cell hardly narrowed above, and abdominal hair-bands 

 composed of .short, appressed pubescence (long in distans).
