ANDRENA HELIANTHIFORMIS, new species. 



Montana. 



Female. — Length, 15 mm. Black; small joints of tarsi reddish. 

 Pubescence ocherous, short, brightly colored, and quite dense on 

 thorax above. Upper side of abdomen with thin short erect white 

 hair, but not hiding surface. Facial quadrangle a little broader than 

 long. Process of labrum very broadly truncate, faintly emarginate. 

 Clypeus shining, with sparse distinct punctures and a faint median 

 ridge, its lower margin overlapped by long brownish hairs. Facial 

 foveae seen from above cream color, occupying about half space be- 

 tween eye and antennae; they do not extend below level of antennae. 

 Flagellum beneath ferruginous except at base, and above the apical 

 margins of the joints are red. Third antennal joint as long as next 

 three together. Mesothorax dull, finely punctured, surface almost 

 hidden by hair. Area of metathorax granular. Metathorax dis- 

 tinctly truncate posteriorly. Tegulae ferruginous. Wings dark red 

 brown; nervures fuscous, the small slender stigma darker. Basal 

 nervure meeting transverse median. Transverse median strongly bent 

 near lower end. Second submarginal cell extremely broad, receiv- 

 ing first recurrent nervure beyond middle. Hair on hind tibiae loose, 

 ocherous ; abdomen dull, with small, numerous punctures, hair bands 

 very thin; hair at apex light brownish ferruginous; second segment 

 in middle depressed about one-third. 



Type. — Collection of the American Entomological Society. 



Resembles A. Jiaynesi, but readily distinguished by the shining 

 clypeus, light tegulae, and distinctly punctured abdomen. Compared 

 with A. JbeliantTiiformis, A. sayi has a much more shiny abdomen 

 and much broader facial foveae. 



o 28 . Abdomen minutely indistinctly punctured; hair of hind tibiae dark brown.

Female. — Length, 16 mm. Robust, black. Head and thorax with 

 rather short dense fulvous hair. Hair of middle and hind tibiae and 

 tarsi brownish black, that of hind femora of the same color except at 

 base, otherwise hair of legs fulvous. Facial quadrangle broader than 

 long; malar space distinct; process of labrum emarginate, the labrum 

 below the process densely fringed with red hair. Clypeus with rather 

 close small punctures. Facial foveae seen from above light reddish, 

 occupying fully two- thirds space between eye and antenna; below they 

 end close to eye, a little below level of antennae. Flagellum with the 

 apical part bright red beneath. Third antennal joint as long as the
