NEW EASTERN ANTHOMYIIDAE (DIPTERA) 



BY O. A. JOHANNSEN 



In arranging the Anthomyiidae of the Cornell University Col- 

 lection, for the purpose of listing the New York State species in the 

 forthcoming "Catalogue of the Insects of New York," I found 

 ninety species from this state, about three-fourths of which have 

 already been recorded from the eastern United States. Of the 

 remainder, which cannot be satisfactorily identified with known 

 forms, eight are published herewith as new. The others, since 

 they are represented either by poorly preserved specimens or by 

 females only, it is inexpedient to describe. 



The assignment of the species to genera is in accordance with 

 the recent classification of Schnabl and Dziedzicki, and prac- 

 tically that of Stein in the "Katalog der palaearktischen Dip- 

 teren," Vol. 3. The terminology of the setae of the legs given by 

 Stein has been adopted as being the most natural. The insect 

 is assumed to be standing with the fore and hind femora parallel 

 with the body, the former turned forward, the latter backward, 

 the middle femora at right angles to the body, and the tibiae 

 vertical. When in this position the sides of femora and tibiae 

 turned cephalad are called anterior, those turned caudad are 

 called posterior. The terms extensor and flexor sides are self- 

 explanatory. Thus an outer lateral extensor seta of the fore 

 tibia is one which is on the side of the tibia outward and forward 

 from the body. 



For the benefit of those who do not have access to the work of 

 Schnabl and Dziedzicki, it has been thought useful to give an 

 adaptation of their key to the subfamilies (exclusive of the Mus- 

 cinae) , as well as a short diagnosis of each of the genera, to which 

 species in this paper have been referred. 



Key to the Subfamilies 

 A. Sterno-pleural setae arranged in an equilateral triangle; d. c. 4, rarely 3 or 

 5; the seta on the posterior median extensor surface (calcar of Schnabl) of the 

 hind tibia placed very low, becoming preapical in position; eyes of both male 

 and female usually widely separated; anal vein abbreviated; wing not rilled;
