250 Mr. E. Saunders' Synopsis of 



tibiae with bright fulvous, tarsi with dark brown. Length 

 11 — 14 mm. 



Hah. A common species in spring, April and May. 



I do not think this species can well be confounded 

 with others ; it is most like atriceps, but the clear testa- 

 ceous tibiae of the ? in that species and the clathrate 

 basal area of the metathorax in both sexes at once 

 distinguish it ; the bright fulvous scopae separate the ? 

 from that sex of Trimmerana and its allies, and the 

 short antennae the <? . I have been able, through the 

 kindness of Mr. C. W. Dale, to examine the type of 

 aprilina, Smith, which is only a stylopised form of 

 the (? of the above.
