ART. 8 REVISION OF THE FLY GENUS BELVOSIA ^ALDEICH 23 



Wings and both calypters brown. 



Female. — Front rather narrow for this sex, measuring at vertex 

 0.35 to 0.37 of the head width; three pairs of procUnate orbitals. 



Length, 12-14 mm. 



Described from 24 specimens of both sexes. The principal series, 

 including type and allotype, were reared by Hy. Edwards from a 

 Hesperid, collected in Mexico, without more definite locality. This 

 series, including 11 specimens, bears the Edwards number 15671 and 

 is received from the American Museum of Natural History. Other 

 specimens received from the same museum include three from 

 Tacubaya, D. F., Mexico (William M. Wheeler), and one from Brazil 

 (H. H. Smith). In the National Museum collection are the following 

 specimens: One from Ancon, Canal Zone, collected by A. H. Jennings, 

 identified by Coquillett as Behosia analis Macquart; one from Mex- 

 ico without collector, with the same identification; one labeled "on 

 Automeris leucane Mex."; one, Mexico City (O. W. Barrett) from 

 the collection of C. W. Johnson; two, Federal District, Mexico (one 

 from Juan Mtiller); one, Jalisco, Mexico, bred from Copaxa laven- 

 dera ?, reared by H. L. Bowers; one, Cordoba, Mexico, collected by 

 William Schaus; one female from Mountain Grove, Mo. (M. P. 

 wSomes) . In Professor Hine's collection there is one specimen from 

 Mexico. There is another in the Canadian National Collection, 



Paratypes. —M&\es, Cat. No. 40476, U.S.N.M. 



BELVOSIA CILIATA var. FORMOSA, new 



This variety is the same as the preceding except that the band 

 on the third abdominal segment is very much wider, covering a little 

 over one-half of the segment at the base; it is narrowly but distinctly 

 interrupted. 



Described from 11 specimens; 3 males, including the type, are from 

 St. Clair, British West Indies (F. W. Urich), reared from larva of 

 Automeris species; the allotype is from Ancon, Canal Zone (A. H. 

 Jennings) ; 2 specunens in the Canadian National Collection from 

 Mexico, bred from Saturnia orizaha by N. K. Bigelow; 1 specimen in 

 the American Museum of Natural History from Chapada, Brazil (H. 

 H. Smith) ; 1 specimen from Higuito, Costa Kica (Pablo Schild) ; there 

 is also a male in the Vienna Natural History Museum, which I have 

 lately examined and I am including as a paratype. It is labeled "Brazil 

 Coll. Winthem" and came to me under the identification esuriens 

 Fabricius. 



Type.— Male, Cat. No. 40477, U.S.N.M. 



Some of the specimens approach rather closely to hicincta, but can 

 be separated very easily by having the pollen of the fourth abdominal 

 segment extending to the extreme apex.
