13G THE CANADIAN ENTOMOLOGIST. 



o* • — Resembles the female ; clypeus strongly produced, entirely 

 green ; labrum dark rufopiceous ; flagellum testaceous beneath ; tegulas 

 with more yellow than in female and with no black spot ; mesothorax 

 more closely punctured; legs green, tarsi ycl/ow, testaceous at tips, legs 

 with pale pubescence ; abdomen shining, closely punctured, pubescence 

 as in female, but the short pale pubescence of the segments is heaviest 

 near the apical margins of the segments ; fourth ventral segments so 

 produced posteriorly in the middle as to form two deep curves on each 

 side (see drawing). Length, 9 mm. 



Described from a male (Aug. 19) and a female (July 17) taken on 

 Cleome serratula, in Horsetooth Gulch, near Ft. Collins, at an altitude of 

 over 7,000 ft. 



This species differs from A. humeralis, Patt., as identified by 

 specimens in the collection here, by the pale ochraceous pubescence, 

 prothoracic margin not sinuous, posterior truncation not shining, median 

 groove shallow, legs blue-green, not black beneath, hind tibial spur of 

 female ; colour of tegulas ; and first three ventral segments being green. 

 The male most resembles A. fervidus, Smith, but that is described as 

 having long white hair on the legs, and tarsi pale testaceous with yellow 

 hair.

 segments, where it is longer and forms yellowish ochraceous hair-bands ; 

 face and occiput, excepting clypeus and supraclypeal space, very closely 

 densely punctured ; clypeus with elongate shallow separate punctures, 

 and slightly produced, hardly truncate at tip, shining ; supraclypeal space 

 with round separate punctures ; face and cheeks with rather long dense 

 white hairs ; mandibles with a green spot at base, rufous in middle and 

 with darker tips ; only the scape and three joints of the flagellum remain ;

 Prothoracic angles sharp, more prolonged than in A. cleomis, joining the 

 prominent green tubercles by a curved line, which is fringed with short 

 hairs ; mesothorax finely closely punctured ; scutellum with fine punc- 

 tures, not very close in centre ; postscutellum finely continently punctured; 

 disc of metathorax shining, green, punctured, lateral angles sharp, base of
