TAXONOMY OF MUSCOIDEAN FLIES — TOWNSEND II3 



genus peculiar to the pine region, and which both passes the winter 

 and nests there. Likewise a species of trogon occurs, belonging to 

 the monotypic genus Buptilotis, also peculiar to the same region and 

 breeding there. 



Parade jeania may be considered as more or less of a boreal off- 

 shoot from De jeania, and D. vexatrix Osten-Sacken is a boreal and 

 distinct form from the tropical corpulenta Wiedemann. Osten- 

 Sacken was mistaken in taking Wiedemann's type to be the same as 

 vexatrix. 



PTEROTOPEZA, nom. gen. nov. 



This name is proposed for Clicctoprocta Brauer and von Bergen- 

 stamm (1891), which is preoccupied by Niceville in Lepidoptera 

 (1890). Type is Blepharipeza tarsalis Schiner, of South America. 



Genus Gymnochaeta Robineau-Desvoidy 



Gymnochceta alcedo H. Loew. — This species is not typical of the 

 genus Gymnochceta. The type of the genus is viridis Fallen, which 

 has second antennal joint elongate, second aristal joint elongate, an- 

 tennas inserted a little below middle of eyes, and cheeks one-half 

 eye height. 



EUJURINIA, gen. nov. 



This genus is proposed for Hystricia pollinosa van der Wulp. An- 

 tenna?, frontal bristles, arista, and palpi like Jurinia, but resembling 

 Hystricia in having the eyes hairy and the cheeks not so wide. It 

 differs from Jurinella in the narrower cheeks and wider parafacials, 

 and from Pseudohystricia in the first of these characters and the less 

 produced front. 



The cheeks of Jurinia are nearly equal to eye height, and the eyes 

 are bare. Hystricia has the third antennal joint truncate at tip, 

 second joint not so elongate, but attenuated at origin ; frontal bristles 

 weaker, straighter, descending lower, and all directed forward ; no 

 macrochaetse on lower border of cheeks, second aristal joint not 

 strongly elongate. 



A female specimen in U. S. N. M., collected by the writer July 3, 

 at San Rafael, near Jicaltepec, Veracruz, is apparently to be identi- 

 fied as Eujurinia pollinosa, although van der Wulp says "arista 

 indistinctly jointed," which, it seems, must be an error, and not 

 intended by the author. The first two aristal joints in above speci- 

 men are elongate and distinct. Also there are some fine strong 

 bristles on under side of middle femora. Length, 16 mm.
