NORTH AMERICAN DIPTERA. 307 



9Iorinia sp. 



I have species of this genus agreeing closely in their generic char- 

 acters with European specimens. 



Plirissopocia prseceps Wiedemaim. 



I have specimens of this very large Sarcophagid, agreeing well 

 with Wiedemann's description, from San Domingo. 



Hypodernia liiieata Villers, etc. 



I have specimens of this species from Northern California and 

 Arizona. 



<£<leinagena tarandi Liune, etc. 



I can confirm the statements of the occurrence of this species in 

 America. I have seen specimens from Alaska. Richardson (Fauna 

 Boreali) speaks of the occurrence of a bot-fly in great numbers in the 

 American Arctic regions ; it is probably this. 



Oclitliera mantis Degeer. 



I am unable to distinguish Californian and Eastern specimens of 

 this common species. 



Oclithera exsculpta Loew. 



I have specimens of this Cuban species from the Southern States. 



Spilographa electa Say. 



Mr. Pergande has sent me specimens of this species bearing the 

 label " Bred from berries of Sokmum Carolina, Oct. 7, 1877." They 

 were from Missouri. 



Cepltalia ruflpes Meigen. Syst. Beschr. v, 291, 1, pi. xlvii, fig. 15 ; Schiner, 

 Fauna Austr. ii, 176. 



Specimens from Virginia, collected by Mr. Pergande in June, 

 agree so closely with the description of this European species, that I 

 believe the species the same. The legs and front are dark, the hind 

 femora and tibiae almost wholly black. The fly is very singularly 

 ant-like in appearance.
