EUPARAPHYTO, new genus. 



Belongs in the Sarcophagidse in the neighborhood of Sarcophaga, 

 from which it differe in the practically bare arista, the strong bristles 

 of parafacials, the facial and antennal structure, strong costal spine, 

 etc. From Paraphyto it differs in the single row of frontal bristles, 

 which descend below base of second antennal joint, the bristles of 

 parafacials, etc. The description is drawn from a single female 

 specimen. 



Front elongate and broad, longer than facial plate, wider at vertex 

 than one eye, a strong pair of ocellar bristles, two proclinate and one 

 divergent-reclinate pairs of orbital bristles. Parafacials very broad, 

 with about four strong bristles in a row near lower eye-margin; 

 between these and frontal bristles are several weak hairs. Facial 

 plate short, deeply bowed, the oral margin thus being prominent, 

 the vibrissas inserted practically on same. Facialia with a few short 

 bristles next vibrissas, latter a little longer than the peristomal 

 bristles. Second antennal joint hardly elongate, third joint no longer 

 than second; arista thickened on basal one-third, with only the 

 faintest microscopic pubescence on thickened portion, basal joints 

 short. Cheeks nearly two-thirds of eye-height, fully one-half same 

 in least width, fully twice as long as wide, spareely set with bristly 

 hairs. Proboscis subhorny but stout, part beyond geniculation 

 much less than head-height; palpi elongate, widened apically, a 

 little shorter than proboscis beyond geniculation. 



Three sternopleural and three postsutural bristles. Scutellum 

 with four rather strong, long, nearly straight marginal bristles, the 

 inner pair widely separated; the discal weak pair nearly atrophied, 

 but distinct. Abdomen without dorsal bristles on first three seg- 

 ments, but second and third segments with one lateral marginal 

 bristle, and first segment with several lateral bristles and a median 

 ventral pair, the venter otherwise without bristles; fourth segment 

 with a marginal row, becoming gradually hairlike on venter. Wings 

 with a long and strong costal spine, the venation as in Sarcophaga, 

 the apical cell very widely open. 



Reproductive habit unknown, but most likely larviposition from 

 a double-sac uterus. 



Type-species. — EuparapTiyto alpina, new species. 



EUPARAPHYTO ALPINA, new species. 



Length of body, 8 mm.; of wing, 8 mm. One female, Tirapata, 

 Peru, on the high puna of the Lake Titicaca region, about 13,000 

 feet, January 28, 1910, on flowers of the dwarf flora. 



Head black, more or less silvery. Antennae and palpi soft black. 

 Facial plate black, thinly silvery pollinose. Parafrontals silvery, 

 faintly golden on middle. The broad frontalia soft black in a direct
