10. LAPHRIA 703 



stated that the lower half of the face-beard is sometimes brownish yellow, 

 and that some of the hairs on the underside of the basal joint of the 

 antennae may be also brownish yellow, while apparently continental speci- 

 mens have the last segments of the abdomen with more extended black 

 pubescence. There is no Asilid in Britain at all allied to this species, 

 but some European species of Laphria are rather near it and I am unable 

 to satisfactorily distinguish L. dioctriceformis. 



L. marginata is not uncommon in large woods in the southern half of 

 England. My records are from Hampshire (New Forest), Sussex (Plashett 

 and Abbott's Woods), Kent (Darenth), Essex (Leigh), Suffolk, Berkshire 

 (Tubney Wood), Herefordshire (Stoke AVood, etc.), and Nottinghamshire 

 (Treswell Wood), from June 14 to August 18; B. Cooke recorded 

 (Naturalist, v., 134) a pair from the Cheshire coast. A female in the 

 Hope Museum at Oxford is labelled as having been bred from the refuse 

 of a hornet's ( Vespa crabro) nest. It is recorded from almost all Europe.
