FAMILY DOLICHOriD.E — THE LONG-HEADED FLIES 231 



acters arc true of Parasijntonnon also, but all the species of Synarthrus 

 Loew have both the propleura and hypopleura haired, (lenitalia small. 

 Genotype : — Parasifntonnon montivaguyn Wheeler. 



P. aselhis Wheeler is the onlj' species I have seen belonging to 

 Parasijntormon. The genus Eutarsus Loew is close to Neosijntormon 

 but both the propleura and pteroplcura bear fine hair, as in SipuirtJirus. 

 Eutarsus does not occur in America. 



Peloropeodes Wheeler 



In his original descrii)tion of this genus one might infer that the 

 arista is apical, but I believe this is erroneous and that the arista is 

 inserted toward the end of the third segment in the male. The type 

 males of sahtx Wheeler, the genotype, all lack the third antennal seg- 

 ment so the point cannot be cleared up at present. Both females, 

 however, are in excellent condition and since no type has been selected 

 for the species, I now select one of the females. On general structure 

 there can be no doubt that both Pachupyga Parent and Kophosoma Van 

 Duzee are synonyms. 



Teuchophorus Loew 



Wlieeler has described a species from South Dakota which appears 

 to have been correctly placed. The type is not in good condition, both 

 wings being absent and part of the abdomen eaten away, but from 

 what can be seen the specimen agrees well with European material 

 taken near Leningrad. This genus is very clo.se to Peloropeodes differ- 

 ing in having small genitalia, as in Sijmpycnus, less evident anal angle 

 to the wings with less developed sixth vein, and the absence of a pair 

 of small basal bristles on the scutellum in addition to the large pair. 

 As a rule there is a i^air of small hairs on the apical i)ortion of the 

 scutellum, absent in the species of Peloropeodes I have seen. 



Millardia, new genus 



This genus is proposed for the reception of species formerly placed 

 in II ydropJwrus JMeigen in which the pteropleura bears conspicuous 

 fine hairs and most, if not all of the species have several pairs of post- 

 vertical bristles instead of a single pair. Genotype: — Ilydropliorus 

 riridiffos Walker.
