ZENILLIA AND ALLIED GENERA — SELLERS 45 



2. CARCELIA INFLATIPALPIS (Aldrich and V/ebber), new combination 



Zenillia infiatipalpis Aldrich and Webbek, Proc. U. S. Nat. Mus., vol. G3, art. 17, 

 pp. 24-25, 1924.— West, Cornell Univ. Agr. Exp. Stat. Mem. 101, p. 814, 1928. 



This species resembles Carcelia formosa very closely, and in many 

 of their characteristics they are identical. The principal points of 

 difference are: Palpus swollen, apical portion destitute of fine black 

 hairs with which the remainder of the palpus is sparsely clothed ; a 

 less pollinose, slightly more subshining species; erect discal bristles 

 on second and third abdominal segments, which are distinctly larger 

 and longer than the surrounding subdepressed abdominal hairs. 

 Females of C. formosa have a very few weak, erect hairs in the discal 

 region, but they are the same size as the surrounding subdepressed 

 abdominal hairs. 



The following characters are perhaps worth mentioning, otherwise 

 the description is the same as for formosa'. Head with front of 

 female at narrowest 0.27 head width ; frontal orbit, face, cheek, and 

 posterior orbit silvery pollinose; antenna black, first and second 

 joints not faintly reddish, third antennal segment two and one-half 

 to three times length of second; arista tapering from base to apex. 



Abdomen black, gray-pollinose, heavy pollen more confined to sides 

 and bases of segments; dorsum of first segment and apical portion of 

 other segments more or less shining black; no distinct abdominal 

 dorsal vitta ; in type specimen erect bristles in discal regions of second 

 and third abdominal segments almost approaching small macro- 

 chaetae in size, this character not so pronounced in other specimens, 

 but the erect bristles are larger and stronger than surrounding sub- 

 depressed abdominal hairs. 



Length 9 to 10 mm. 



Type locality. — Great Falls, Va. 



Distribution, — Virginia 1, Indiana 1. Published record: New 

 York (West). 



Type.— Female, U.S.N.M. No. 25706. 



Host. — Unknown. 



Remarks. — The foregoing statements are based on the examina- 

 tion of the type, June 12 (Banks) ; the female paratype, Lafayette, 

 Ind., September 14, 1917 (Aldrich) ; two females, Great Falls, Va., 

 August 14, 1919 (Greene). The last two females were removed 

 from the Carcelia formosa material where they were with a female 

 of C. formosa (Greene) having the same date and locality. 



3. CARCELIA GNAVA (Meigen) 



This species closely resembles the genotype Carcelia bombylans 

 Robineau-Desvoidy. For many years C. gnava of Macquart (nee 

 Meigen) was accepted as the genotype. The complete Palearctic
