142 BEES OF GREAT BRITAIN. 



fasciae as in the other sex, but the fascise not quite so widely 

 interrupted, B.M. 



Var./3. The basal segment of the abdomen immaculate. 



This is a very local species, parasitic on Eucera longicornis, 

 probably it will be found wherever colonies of that bee are met 

 with] it occurs at Southgate in plenty, infesting Eucera. I 

 have not seen any specimens from the north of England.

Male. — Very closely resembling the female, but having the cly- 

 peus anteriorly, the sides of the face, the scape in front, the 

 labrum and mandibles, yellow; the latter ferruginous at their 

 tips ; the scape black above, and the four or five basal joints 

 of the flagellum having a black spot above ; the head and thorax

 in front, a spot on each side of the breast in front, yellow; 

 wings subhyaline, the nervures pale ferruginous, the apical 

 margins faintly clouded as in the other sex ; the abdomen as

This is a very abundant species, found in all parts of Great 

 Britain; it is not subject to vary in its markings, but some- 

 times the legs are dashed with yellow', particularly at the knees ; 

 sometimes the post-scutellum is black ; the fascia on the basal 

 segment of the abdomen is also occasionally entire.
