bead, more obsoletelj punctured thorax and much longer

scribed. 



Usually found in chalky districts (Croydon, Isle of Wight, 

 Erith, Seaford, Caterham), and associated with ants. 



This species, which has somewhat the appearance of a 

 very small specimen of S. elongatulus (from which its 

 unpunctured thorax, the basal furrow whereof has no middle 

 keel, and its less convex elytra, at once distinguish it), is 

 possibly the Spcn^shaUii of Schaum and Redtenbacher, but 

 not of Denny, which is lighter in colour, shorter, broader, 

 and more convex, with 2 foveas on each side of the thoracic 

 basal groove, more evidently punctured, with larger eyes, 

 autenna3 less stout at the apex, &c.

This species cannot as yet be considered truly indigenous, 

 as I now think that the single male example which I have 

 referred to it is only a highly developed $ of H. strigosus. 

 Since my notice above quoted, I have seen many examples 

 of the latter species, taken by Mr. E. A. Waterhouse and 

 myself at Bognor, Mr. Champion and Mr. Lawson; and I 

 find, as might indeed have been expected, that it varies 

 very much both in size and development. My former 

 exponents were, though of both sexes, of slight build.

Apparently allied to A. hybrida, Er., but having the 

 lateral edges of the elytra sparsely set with short seta?, and
