A NEW NEMESTRINID FLY FROM CENTRAL TEXAS. 



By J. Bequaert, 

 New York City. 



For some time past, I have gathered notes on the North American 

 species of the dipterous family Xemestrinidx, my interest in the group 

 having been aroused by the capture of several specimens during the 

 Cornell Biological Expedition of 1917. Through the kindness of 

 some of my entomological friends I have been able to study much 

 valuable material, including all but one of the species known from 

 America north of Panama. Certain peculiarities of this family, how- 

 ever, render the examination of large series of specimens and the 

 comparison of species from different regions imperative, before its 

 classification can be established on a safe basis. I hope to have time 

 and opportunity to do this in the near future; meanwhile, it seems 

 necessary to publish the description of the following new species, 

 since it has been distributed to several public and private collections. 



Hirmoneura bradleyi new species.* 



Type female from Anhalt, Comal Co., Texas, June 28, 1917 (J. 

 Bequaert Coll.), collection of the American Museum of Natural 

 History. 



A large-sized, black and rufous or dark brown species, with feeble pilosity; 

 the dorsum of the thorax with conspicuous longitudinal bands, alternately brown 

 and gray pruinose ; the abdomen above with white pollinose transverse fasciae 

 alternating with dark brown bands ; antennae and palpi brownish-red ; legs 

 yellowish-brown, hind tibiae dark brown, hind tarsi black; eyes bare, broadly 

 separated on the front in both sexes ; wings with two submarginal cells only ; 

 the second submarginal and the second posterior cells broadly open on the 

 margin. 



Female. — Integument dark colored, blackish-brown to black, more brown- 

 ish-red in places and the limits between the different tinges ill-defined, varying 

 from one specimen to another; in some, the abdomen is extensively rufous, 



1 Named for my esteemed friend Prof. J. Chester Bradley, of the Depart- 

 ment of Entomology, Cornell University, successful leader of the Cornell Bio- 

 logical Expedition, which during the months of June, July and August, Kjr-, 

 crossed the United States by automobile; the species described herewith was 

 taken on this journey.
