SYNOPSIS OF THE BRITISH PHRYGANTD^. 91 



Length 5| lin. ; exp. 12 lin. (Stephens). 

 Hab. London, in June ; not common. 



I have not this species before me. When I examined the 

 type I declared it to be a new Anabolia, not described else- 

 where, and which had not previously occurred to me. The 

 description is greatly in favour of A. ditbia being the Plia- 

 copteryx granulata, Kolen. ; yet I believe that in comparing 

 the types I found differences between them. The species 

 requires further investigation. I have noted that in Curtis's 

 collection the Phac. granulata, Kolen., is ticketed as L. bre- 

 vipennis ; it consequently occurs in England. 



Genus Stenophylax, Kolenati. 

 Hallesus, Stephens (partim). 



Joints of the palpi cylindrical, thin ; first joint of the 

 antennae shorter than the head ; wings pretty thickly clothed 

 with short hairs, the anterior much widened towards the 

 apex and obtusely rounded off; spurs 1,3,4; tibiae with 

 short spines. 



Case rather irregularly constructed of small stony frag- 

 ments, cylindrical, with the head-end rather wider and 

 surrounded by larger stones. 



This genus also is very nearly related to Limnophilus, 

 and has been re-united therewith by Brauer. Its habit is 

 peculiar, and differs in the broad obtusely rounded anterior 

 wings. 



The species belonging here are excessively similar in form 

 and coloration, and are often confounded together. By the 

 app. anal. I now distinguish sixteen European species. When 

 I examined the types of Stephens and Curtis, a portion of 

 these species, especially those described by Pictet, were still
