connected with which are elaborated to a degree, and of 

 which the remarkable structure of the female and her way 

 of life, are items which it very largely explains. I cannot

Description of Figures. 



Pupa-cases of H. canalensis (fig. 1) and H. paradoxa 

 (fig. 2) longitudinally divided and placed on slides — all 

 contents preserved. Photographs by A. E. Tonge, Esq. 

 The amplification is four diameters. 



The H. canalensis pupa has no contents, but a few grey 

 pellets of maternal urates. 



The H. parodoxd has similar pellets, but also contains 

 larval skins, of which the heads are very conspicuous, cast 

 on their first moult by the young larvae. There is no 

 larval frass. There is in neither case any trace of the 

 mother except the pellets of urates. 



The more solid abdominal ends of the cases are split 

 irregularly.
