cies, Proc. U. S. N. M., 620) held the same opinion. 

 After examining a pair of the European Sarcophila 

 latifrons in Professor Melander's collection, I see that 

 Wohlf ahrtia is very distinct from that genus, in which 

 the bucca is narrow, the front not protuberant, and 

 the head of entirely different shape, not to speak of 

 other differences. 



Brauer and von Bergenstamm included two spe- 

 cies in the genus, Sarcophila magnifica and meigenii 

 of Schiner; in the third paper mentioned above, they 

 named the former as type. In the generic descrip- 

 tion, they attribute two pairs of orbital bristles to the 

 male in both species; in one male of magnifica in the 

 Hough collection there is only a single orbital pair, 

 and in two males of meigenii (all these are European, 

 presumably named by Strobl) there are none, as in 

 our IS^orth American species. As Professor Bezzi has 

 pronounced one of our species identical with meigenii, 

 it is evident that an error was made in the original 

 generic description. 



Generic characters: Front and epistoma pro- 

 duced, giving the head a rather square outline in pro- 

 file; front wide in both sexes, but more so in the fe- 

 male; third antennal joint not much longer than the 

 second (except in the European W. mamma) ; arista 

 pubescent; bucca high; parafacial with a few small 

 hairs not in rows; ocellars and outer verticals ])resent 

 in both sexes ; back of head with only black hairs. 



Thoracic chaetotaxy {magnifica, from specimen 

 in the Hough collection) : ps dc 4; ant dc 3-4; ant acr 

 about 4 pairs present; post acr 2 pairs large in male, 

 one in female ; hum 3 ; posthum 2 ; prs 1 and an inner 

 very small; stpl 2 and a small below the front one; 

 scutellum with 4 marginals, the fourth pair close to- 

 gether, no small apicals between them; subapicals, 2 

 rather large on one side and one on the other in the 

 specimen; pa 2; sa 2. 



Abdomen densely, uniformly pollinose, w^ith per- 

 manent black shining or subshining spots in three 

 longitudinal rows.
