In this diagram I have marked the place of Sirex, Sialis 

 and Boreus, as belonging to osculant orders, to which I 

 have ventured to give the usual terminations in ptera, al- 

 though ignorant of the just Umits of such groups. If indeed 



that we may account for the singular analogy which the larvae of certain 

 Blatta bear to GLomeris. Some interesting examples of this may be seen 

 in the collection with which Dr. Horsfield has lately enriched the Museum^ 

 of the East India Company. i
