ART. 7 AMEEICAN MUSCOID FLEES IN VIENNA MUSEUM — ^ALDEIOH 17 



This species is in the National Museum, as I find the following 

 specimens: Three males, Eio Charape, Peru, 3,700-4,500 feet, Sep- 

 tember 17 and December 12 and 15 (Townsend) ; one male and one 

 female, Casahuiri, Peru, February 4 and 14 (Townsend) ; one male, 

 Las Cascadas, Panama, March 3, 1909 (A. H. Jennings). I refer 

 the species to the genus Urodexodes Townsend, described in Pro- 

 ceedings of the U. S. National Museum,^^ with the single species 

 charapensis, new, from Rio Charape, Peru. U. cingulata differs 

 from charapensis, the genotype, in having yellow palpi, distinct but 

 small ocellars, much more sharply defined silvery poUinose bands on 

 the abdomen, and the wings hardly infuscated. 



95. LIXOPHAGA FAMELICA Wiedemann

 Oymnostylia famelica Bbaueb and Bergenstamm, Denk. Wien. Akad. Wiss., 

 vol. 58, 1891, p. 405. 



One male, considerably broken, " Brasilien, Coll. Winthem," agree- 

 ing with "Wiedemann's description. It is a Lixophaga closely related 

 to variaMlis of North America. 



Black with yellowish-gray pollen. Front 0.254 of head width; 

 without orbitals. Third antennal joint three and one-half times the 

 second; arista with basal joints short. Palpi yellow. Acrostichal, 

 3, 3; dorsocentral, 3, 3; sternopleural, 2, 1. Mesonotum with rather 

 dense yellowish pollen on which are two pairs of shining black 

 stripes, the outer broader and interrupted. 



Abdomen rather narrow, with basal crossbands of yellowish 

 pollen on second, third, and fourth segments, which occupy nearly 

 half the length, are slightly interrupted at median line, and bear 

 numerous small black dots from which the hairs arise. No discals 

 even on the fourth segment, one pair median marginals on first and 

 second segments, a marginal row on third and fourth. Third seg- 

 ment with no matted or chistered hair on ventral side. A trace of 

 yellow ground color on sides of second segment. 



Legs l)!:u-k. claws and pulvilli moderately elongate; middle tibia 

 with one hi-istlo on outer front side, hind not ciliated. 



The species hardly dill'ei's from variabilis except in having fully 

 the posterior htilf of abdominal segments 2, 3, and 4 shining, while 

 in varinhiiiH the pollen covers all except a narrow hind margin. 



Not in United States National Museum.
