Var. jS. The thorax anteriorly has a mixture of cinereous hairs ; 

 the first and second segments of the abdomen have a lateral 

 tuft of cinereous pubescence. {A. Albinella, Kirhy.) 



Var. y. The thorax anteriorly and posteriorly cinereous, the ab- 

 domen cinereous at the base. {A. frutetorum, Kirby.) 



Var. S. The thorax anteriorly and posteriorly and the basal seg- 

 ment of the abdomen covered with cinereous pubescence ; the 

 second and following segments have fulvous pubescence. 



The variety of the female has not occurred in this country, 

 but it is met with on the continent; it is probably the Apis are- 

 naria of Panzer. Of the male, var. /3. is the A. Albinella of 

 Kirby^ var. y. the A. frutetorum of Panzer, and var. 8. probably 

 the A. pomoriim of that author ; the latter variety is rare. The 

 species is occasionally met with in the London district, but it is 

 not abundant. The female once occurred in great numbers 

 it Coomb Wood, Surrey : the males are frequently met with, 

 nd below Southend they have been observed in profusion 

 n the month of iVugust : this species is probably the parasite of 

 B. lapidarius.
