374 Mr. Cameron's descriptions of new Cynipidce. 



punctured pronotum and scutellum, sufficiently separate 

 it from the common species ; in having the pronotum 

 punctured it agrees with A. pwwticollw, Eeinh. (which 



I regard as only a variety of Dalmani), but the striated 

 mesonotum, the large foveae at apex of mesonotum, the 

 less strongly punctured scutellum, the almost obsolete 

 scutellar foveas, mark it out as a very different species. 

 A. subulifera, which has the mesonotum transversely 

 striated, differs in the scutellum ending in a blunt 

 spine. 



Hob. Mugdock, near Glasgow. 



The following table will, I believe, enable our species 

 of Aegilips to be identified. A. Dalmani, I may add, 

 is the most variable species ; the legs vary from ferru- 

 ginous to piceous, and the posterior femora, tibiae, and 

 tarsi may be for the most part black or fuscous ; the 

 antennae may be entirely black, or brownish, or reddish 

 on the under side ; while the collar and the apex of 

 mesonotum are sometimes aciculated, or even punctured. 

 It is often found on windows.
