importance to my present object, and 1 have thought it best 

 to follow Mr. McLachlan's list already alluded to, of which, 

 mdeed, this paper may be considered an enlarged second 

 edition. 



Group PSEUDO-NEUEOPTERA. 



The development is direct — that is, there is no quiescent 

 pupal stage. The larvae somewhat resemble the adult, but 

 are without wings, which are developed externally. 



Aetificial Key to the Families. 



Hind wings folded longitudinally, broader than fore wings PerlidcB. 

 Hind wings not folded. 



Hind wings as large as the fore wings . . . . TermitidcB. 



Hind wings smaller than the fore wings.

Family TERMITID^. 



The white-ants have the head horizontal and the antennae 

 short. The wings are long, narrow, and straight ; the 

 anterior and posterior are equal in shape and size ; they are 

 finely net-veined. The abdomen is ovate, and composed 

 of ten distinct segments. The larvae resemble the adults. 

 Artificial Key to the Genera. 



Antennae 16- to 20-jointed . . . . . . . . Calotermes. 



Antennte 12- to 14-jointed . . . . . . . . Stolotermes. 



Genus Calotermes, Hagen (^1853). 



Head rather small, triangular or rounded ; eyes large, 

 ocelli small ; antennte as long as the head, 16- to 20-jointed. 

 Prothorax as wide, or nearly as wide, as the head, transverse, 

 truncate or arcuate in front, w^th the sides and apical edge

 connected with the costal by five or six nervules crossing the 

 costal area. 



Soldiers short and stout, with a large cylindrical head,
