 Nemeritis canescens Morley, Brit. Ichn., vol. 5, 1914, p. 133. 



This is a well-known cosmopolitan parasite of lepidopterous 

 larvae in stored grains, etc. The synonymy of ephestiae and 

 oahuensis with canescens was demonstrated by Morley, and 

 there can be no doubt thatfrumentarius is also synonymous since 

 both the description and the host relations agree. Specimens 

 in the National Museum labelled in Ashmead's hand Omorga 

 columbiana are the same species as those determined by Gahan 

 as frumentarius and as the paratypes of oahuensis. There is 

 considerable variation in the color of the legs and abdomen, and 

 many specimens agree with Say's description of ductilis.

We do not believe that Nemeritis Holmgren, Omorgus Foerster, 

 and Idechthis Foerster are generically distinct from Camoplex.
