282 Mr. F. Smith's Revision of - 



Nylander is of opinion that the male constitutes the Stenamma 

 Weshvoodii, this is probably the case ; I have long suspected 

 Stenamma to be a male of one of the small species of Myrmica. 

 The female and worker were first discovered in this country 

 by Mr. Waterhouse, in the nest of Formica riifa ; Nylander 

 says it also frequents the nest of F. congerens. The constant 

 habit of this species appears to be to take up its abode in the 

 nests of Formicidee, whilst Myrmica hirtula is only to be found in 

 company with Myrmica muscorum, and Myrmica sublcevis in the 

 nests of Myrmica acervoriim ; the two latter species have not yet 

 been discovered in Britain.
