TAXONOMY OF MUSCOIDEAN FLIES TOWNSEND \OJ 



Genus Tachinomyia Townsend 



Tachinomyia robusta Townsen'd. — The genus differs from Tachina 

 in the vibrissa; being inserted higher above oral margin, cheeks one- 

 half eye height in width, and abdomen very elongate. 



Genus Emphanopteryx Townsend 



Bwphanopteryx eumyothyroides Townsend. — This genus differs 

 from Cryptomeigcnia by having the abdomen large; claws and pul- 

 villi of female elongate, those of male very long and strong; arista 

 finely pubescent, strong subdiscal and discal macrochaetae (at least 

 on second segment), fourth vein rather angular at bend and usually 

 represented beyond apical crossvein by a short stump. 



Subfamily Tachixix/k 

 Genus Tachina Meigen 



Tachina clisiocampcc Townsend. — -Achcetoneura femaldi Williston 

 is very probably a synonym. The strongly marked wrinkle at an- 

 gular bend of fourth vein, the elongate second antennal joint which 

 is about three times as long as first, the frontal bristles descending 

 low on parafacials, and the strongly ciliate facial ridges, whose 

 bristles ascend at least to opposite the lowest frontal bristles, make 

 the species typical of Tachina s. str. The third antennal joint is 

 about twice as long as second. Achcetoneura has the second anten- 

 nal joint hardly longer than the first, the third joint thus being easily 

 five or six times as long as the second. 



This species can not be identified with T. mella Walker, if the de- 

 scription of latter is to be depended on, since it states that the 

 second antennal joint is ferruginous apically, third joint three times 

 as long as second, arista much longer than third antennal joint, 

 second aristal joint moderately long, large ferruginous spot on each 

 side of second segment. The venational characters also do not 

 agree. In clisiocampce there is at most in either sex only a very 

 faint tinge of reddish, hardly perceptible in fact, on sides of second 

 abdominal segment. The antennae are wholly blackish, the third 

 joint, even in male, hardly more than twice as long as second, arista 

 but little longer than third antennal joint, apical crossvein well 

 bowed in, hind crossvein quite strongly sinuate. 



Tachina orgyiarum, nom. sp. nov. 



This name is proposed for T. orgyice Townsend, which is preoccu- 

 pied by T. orgyice Le Baron. Both species belong in the genus 

 Tacliina, as here restricted.
