Dasypogon is a handsome genus embracing 44 described 

 European species ; it is closely allied to Asilus, and probably 

 connects that genus with Laphria : it is easily distinguished 

 from either by the nervures of the wings, those of Asilus having 

 2 discoidal cells, and Laphria having a pedicel to the sub- 

 marginal cell, the structure of the antennae is also very dif- 

 ferent to those of the latter genus. 



Hitherto there has been but one species recorded as British, 

 we therefore consider ourselves fortunate in addino- this second 



o 



to our catalogue, and in Mr. Walker's cabinet at Arno's Grove 

 we lately saw another with clouded wings. 



1. D. punctatus Fah. fern., — Panz. 45, 24. — diadema Fah. 



mas., Pajiz. 45, 23. — D. nervosus, Panz. 105, 9, var. 

 Specimens of this fine insect have been taken I believe near 

 Bristol, in sandy situations in June and Jul^^, and are in the 

 cabinets of the British Museum and Mr. Stephens. 



2. D. brevirostris. 



The male of this insect, which is remarkable for the length 

 of its posterior feet as exhibited in the figui'es annexed, I first 

 took at Darent Wood, Kent, the end of June : about the same 

 period Mr. Dale and the Rev. L. Jenyns met with it in plenty 

 on Newmarket Heath, in a place commonly called the Devil's 

 Dyke, and the middle of August I found several pair settling 

 upon the plants that grow in profusion in the North-Foreland 

 meadow, Dover. Its habits are very similar to those of Asilus, 

 and a female that I saw resting upon paling early in the morn- 

 ing exceedingly resembled the smaller species of that genus : 

 at a more advanced period of the day, they became like their 

 congeners very wild and active. 



They are evidently attached to chalky districts, where the 

 plant figured, Chlora perfoliata (Perforated Yellow- wort), is 

 also abundant.
