 Abrachy glossum cockerelli, new species 



Female: Length 10 mm. (without antenna). Head yellow, dark 

 brownish at ocellar tubercle and anterior half of front. Velvety- 

 black frontofacial mark. Antenna dark brown, dark yellow on 

 ventral half of first segment, dark reddish on ventral half of second 

 and third segments. Arista black. First antennal segment three 

 times as long as wide. Second segment two times length of first. 

 Third segment about V/ 2 times length of first. Proboscis black, 

 shorter than length of head. Occiput yellow behind vertex and below, 

 blackish above at sides. 



Thorax black, faint white pollinose forming a distinct pleural stripe. 

 Humeri and distal half of scutellum yellow. Metapleura reddish. 

 Coxae black, white pollinose. Legs yellow, blackish in middle of 

 femora forming a distinct black mark on dorsal apical half of hind

 indistinct brownish band between first and third veins and vena 

 spuria. Calypters yellow. Halteres yellow, dark brown at base. 



Abdomen black. Pale yellowish distal margin on first, second, 

 fifth, and sixth segments. Blackish yellow distal margin on third 

 and fourth segments. Yellowish white pollinose band on distal 

 margin of second segment and sides of distal margin of first segment. 

 Faint white pollinose on sixth and seventh segments. Theca tri- 

 angular, about as long as wide. 



Type: Holotype, female, USNM 64475, Kongaus, Siberia, August 

 1923, Cockerell. 



This species is similar to A. capitatum, but has black on the femora 

 and lacks the yellow pollinose bands on the thud and fourth abdominal 

 segments, although the paler areas preceding these bands are present. 

 The frontofacial mark is very prominent in the new species, a character 

 which has not been mentioned in descriptions of capitatum. In six 

 specimens of capitatum examined, this mark is absent in three, faint 

 in two, and distinct but not as prominent as in A. cockerelli in one. 



Abrachyglossum wui Ouchi, the only other Abrachyglossum described 

 for Asia, is here referred to Siniconops elegans (see below) .
