142 BEES OF GREAT BRITAIN. 



fasciae as in the other sex, but the fasciae 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.

Female. Length 4-5 lines. Black ; the anterior margin of the 

 clypeus, the labrum, mandibles, and antennae, ferruginous ; the 

 inner orbits of the eyes, as high as the insertion of the antennae, 

 yellow. Thorax : the collar, tubercles, tegulae, two spots on 

 the scutellum, one on the post-scutellum, and a dot on each 

 side of the metathorax, yellow ; the legs ferruginous ; the 

 coxae, trochanters, femora beneath at their base, the poste- 

 rior pair also within, black. Abdomen : each segment having 

 a yellow fascia, the first usually interrupted, the two following 

 attenuated in the middle. B.M. 



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 

 have a thin hoary pubescence ; the anterior coxae, the tibiae 

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

 wings subhy aline, the nervures pale ferruginous, the apical 

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

 in the female. B.M. 



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.
