535. line 16. Mr. Gosse, in the Canadian Naturalist, London, 1840, p. 199., 
has described and figured the pupa and imago of an American 
species of Coenomyia, which he had observed amongst the 
grass, extricating itself from the pupa, which “ is large, and 
the hind segments have rings of spines; its colour is chestnut- 
brown, and it much resembles that of a large moth. I have no 
doubt it is subterraneous in the pupastate.” I have followed 
Latreille, the founder of this genus, in writing the name Cx- 
nomyia.
