Halj'dat. — White Mountains, Xew Hampshire (H. K. Morrison); 

 Milwaukee. Wisconsin (Dr. S. Graenieker); and Harrison, Idaho 

 (J. M. Aldrich).

GYMNOMMA QUADRISETOSA, new species. 



Head yellow, upper part of oeciput and sides of front black, yellow- 

 ish gni}' pruinose, hairs of face and cheeks Acllowish white, antenna? 

 yellow, the third joint yellowish brown, sliohtly longer than the second, 

 strong-ly convex on the upper side, proboscis black: thorax black, 

 densely yellowish g'ray pruinose and with four black vitta?. four pairs 

 of postsutural dorsocentral bristles, three sternopleurals, scutellum 

 3'ellowish brown, abdomen black, polished, second segment with a 

 marginal pair of bristles, the third with a marginal row, the fourth 

 covered except on the basal third, on either side of the iirst and second 

 segments are two or three stout bristles; legs black; wings grayish, 

 the base tinged with j^ellow, base of third vein l^earing six bristles, 

 calypteres yellowish smoky brown; leng-th. 12 mm. Five females 

 collected July 15 by Mr. C." H. T. Townsend. 



Ilabltat. — Sierra Madre, Mexico (altitude about 7,300 feet). 



Type.— C^t. No. 6260, U.S.N.M.^ 



^Fahricia infumata Bigot. The type of this species has been examined by Dr. F. 

 Brauer, who reports that it belongs to the genus Parafahrida. The form described 

 under this name in my Eevision of the Tachinidse, page 144, will therefore require a 

 new name, for which palpalis is proposed. The third antennal joint is nearly ellip- 

 soidal in outline, nearly twice as long as wide, as long as the second, arista thickened 

 on the basal four-fifths, the last joint less than three times as long as the preceding, 

 sides of face on the triangular upjier-outer half covered with short yellow bristly 

 hairs, mesonotum bluish gray pruinose. 



Type.— Cat. No. 6234, U.S.X.M. 



Jurinia metallica Desvoidy. Dr. Brauer has also studied the type of this species, 

 and reports that it is evidently the same as Jurinia liiKtricoicIes Williston. The species 

 described as metallica, in my Revision, page 147, may therefore take the name of 

 adasia, which is there given as a synonym of the former. 



■■'The species described in my synopsis of the Tachinidfe, page 145, as Epalpus 

 nigripilosa is not that species, but will form a new genus differing from Epalpus by hav- 

 ing only a median discal and marginal pair of bristles on the second abdominal segment 

 and only a discal pair and marginal row on the third; from Gi/mnomma it differs in 

 that the ocellar bristles are wanting; third joint of antennae nearly twice as long as 

 the second, strongly convex on the upper side, black, the base and remainder of 

 antennjie yellow, arista black, its penultimate joint over twice as long as broad, palpi 

 wanting, eyes bare, thorax black, densely yellowish gray pruinose and with four 

 black vittie, scutellum j'ellow. The genus may be named Parepalpus, new genus, 

 and the species j/avtda, new species.
