mont) ; a female entering burrows of Andrena trimmerana, at Swanston, 

 in June, and both sexes at Aberdour, St. David's, Ronnytoun, Eyemouth, 

 Coniston and Aberdeen (Evans) ; Oxford, and Bovey Tracey, in Devon 

 (Hamm) ; Carlisle (Routledge) ; St. Margaret's Bay, Dover, and Colchester 

 (Sladen) ; St. Ervan, Cornwall (Davies) ; Fleet coast (Richardson) ; Jersey 

 (Ansted's " Channel Islands "). 



It is probably parasitic upon several Noctuids, and has been bred from 

 Diloba coeruleocephala and Hydraecia leucographn. Stephens says it is 

 abundant about London on umbelliferous flowers, and common in/)evon- 

 shire, South Wales, Scotland, etc. Berthoumieu remarks that it frequents 

 flowers of Euphorbiae.

 the remainder being abruptly deep black above ; from the last species
