gins. Wings reddish hyaline, nervures and stigma clear amber. 

 Basal nervure just short of transverse median. Second submarginal 

 cell receiving first recurrent nervure before middle. Third submar- 

 ginal short. Spurs ferruginous. Abdomen shining, with only weak 

 piliferous punctures. Hind margins of segments with creamy white 

 hair bands. Second segment in middle depressed less than one-third. 

 Abdominal segments beneath fringed with ferruginous hair. Apical 

 plate truncate. 



A. lappulae is very close to this, but has the head broader and 

 shorter, pubescence paler (not pale orange or fulvous on abdomen 

 beneath, as it is in tetonorum), lateral face-marks larger, stigma 

 distinctly margined. 



o 18 . No light face-markings (except in A. colletoides). 



a 26 . Large robust species, 15 mm. long or over.

Female. — Length, 16 mm. Black, the small joints of the tarsi 

 more or less reddish, the flagellum hardly noticeably brownish. 

 Pubescence black, except on thorax above, tubercles and middle 

 of metathorax, where it is yellowish white. Facial quadrangle 

 broader than long. Process of labrum narrowly truncate, conspic- 

 uously thickened at end. Clypeus shining, strongly and closely 

 punctured, with a smooth median ridge. Facial foveae seen from 

 above very dark gray, very broad, ending broadly below at about 

 level of top of clypeus. Third antennal joint shorter than next 

 three combined. Mesothorax and scutellum so densely covered with 

 hair that the surface can not be seen, but it is not shining. Area of 

 metathorax dull, feebly transversely wrinkled. Tegulae piceous. 

 Wings dark fuliginous, slightly violaceous. Nervures and the very 

 small stigma piceous. Basal nervure meeting tansverse median. 

 Second submarginal cell receiving first recurrent nervure a little 

 beyond middle. Third submarginal greatly narrowed above. Legs

 Abdomen shining, without distinct punctures, and with no hair 

 bands. 



This is very like A. perimelas, but considerably more slender; 

 stigma smaller and darker (red in perimelas), third transverse cubital 

 with a double curve (upper end straight in perimelas), tubercles and 

 middle of metathorax with light hair.
