the base and above ; tibia? and tarsi black, gL-eyish pollinose, 

 the former thinly clothed, the latter fringed at the sides with 

 black hairs ; claws black, sometimes reddish brown in the 

 middle. 



Wings uniformly light brown ; alulre and squarme also 

 brown, the margin of tlie latter paler and fringed with very 

 short silvery pile ; aluliB very conspicuous when the wings 

 are at rest, directed upwards, and embracing the scutellum on 

 each side. 



Pupa-case black : length 25-26 millim. ; width of seventh 

 segment (the broadest) 15 millim. ; posterior stigmata orange- 

 yellow. 



M^dano Blanco, Sta. Barbara Bay (Grulf of California), 

 Mexico {Lieut. H. 0. Boger, R.N.) ; two specimens, botii 

 males, with their pupa-cases. The papas, from which the 

 specimens subsequently emerged, were found in January 1893, 

 when Lieut. Boger was serving on the Pacific station in 

 H.M.S. ' Melpomene.' The flies appeared in the following 

 March. 



To the anal extremity of each of the pupa-cases are still 

 adhering a number of hairs, evidently those of the host ; they 

 are pale yellowish brown, somewhat curling, and one of 

 them has a distinct black tip. They probably belong to some 

 Rodent, but 1 fear are not sufficient to enable one to hazard 

 even a guess at the host's identity. Lieut. Boger, however, 

 informs me that jack-rabbits (Lepus callotis, Wagler) were 

 abundant in the locality where the larvai were found.

One female, from Ega, R. Amazons, Brazil {Bates). 



In spite of the fact that, as pointed out by Goudot {loc. cit. 

 p. 230), Macquart does not mention that the abdomen of 

 C. cyaniventris is clothed with short black pile, with whitish 

 (yellowish) pile at the base, there can be no doubt that the 

 descriptions of the two authors refer to the same species. The 

 species is redescribed by Brauer (' Monographic,' &c. pp. 267- 

 268) from a specimen in the Imperial Natural History 

 Museum at Vienna.
