Al. socialis. PaijkulL — Steph. Catal. 264. No. 2672. 



Black, rather shining, smooth, somewhat pubescent : head a little narrower

^ZacAr, rather shining- : head narrower than the thorax, triangular-orbiculate : 

 thorax very minutely and very thickly punctulated, with a slight fovea

 Messrs. Turner and Hooker, and in England by Mr. Spence." —

* In this very extensive genus it becomes necessary to attend carefully to 

 the characters of the artificial divisions, in order to arrive at the species^ 

 which are manifestly considerably more numerous than indicated in these 

 pages; as I possess 176 species, above 100 of which were named by Mr. 

 Kirby, and the chief part of the remainder (of my own capturing) were 

 rigidly compared with his collection, and found different, and as I appear to 

 want about 30 of the described species, there must be at least 200 found in 

 Britain, exclusively of the hosts that it is evident remain undiscovered 

 amongst these minute and little investigated species, — a point rendered clear 

 by the recent discovery of the brilliant Elaphrus Lapponicus in Scotland; 

 Agonum fulgens in Yorkshire : Dromius longiceps, bifaciatus, &c. in Cam- 

 bridgeshire; in addition to the novelties recorded in a previous note.
