Genus ENDOIASIMYIA, Big. 



Endoiasimyia, Bigot, Ann. See. Ent. France, (6) ii, Bull. p. cxxxvi 

 (1882) ; and {<6) iii, p. 229 (1883). 



GEJfOTiPE, E. indiana. Big. ; by original designation. 



Entirely like Chilosia in facies, differing practically only in 

 the arista, whicli is conspicuously plumose on both upper and 

 under sides from base to tip, and in tiie absence of eye-margins. 

 The eyes are pubescent, the face strongly i)roduced into a central 

 bump and again above the mouth-opening. Venation as in 

 Chilosia ; tip of 4th vein just appreciably recurrent at extreme tip. 



The whole affinities of this genus appear to be with the 

 Syrphin.e, except for the phnnose arista; but as the latter 

 character is entirely foreign to tliat subfamily, it is not suggested 

 to place this genus there. On the other hand, it is quite incon- 

 gruous as a Yoluceiline.

2 . Ilead'. eyes \\itli short whitisli pubescence; frons at vertex 

 nearly one-fifth of the head, rapidly m idening to antenna^, shining 

 black, with brownish-yellow pubescence and some greyish dust 

 towards sides ; face produced into a large and conspicuous central 

 bump and again produced above mouth-opening; shining black, 

 with whitish pubescence and a little yellowish-grev dust in 

 places and on extreme side margins. Antenna? as in Chilosia, 

 except that the arista is strongly ])linnose on upper and lower 

 sides from base to tip. Head produced in ])rofile distinctly but 

 not greatly })elow eyes ; occiput barely projecting behind eve- 

 n)argins, grey-dusted, with a short fringe on at least lower part. 

 Thorax slightly shining black, with some brownish pubescence on

 yellow pubescence dependent from hind margin. Ahdoinen like 

 that of Chilosia, obconical, of live ol)vious segments, 1st nearly 

 as long as 2nd ; moderately shining black, with short reddish- 

 brown pubescence. Legs slender like those of Chilosia ; coxa) 

 black, femora also black, but narrowly orange-brown at tips; tiI>iaB
