FLIES OF THE GENUS OGCODES — SCHLINGER 271 



legs yellow except for black coxae, dark brown femora, and light 

 brown tarsal apices; claws nearly black; wing hyaline, veins white, 

 indistinct, but venation strong (pi. 3, fig. 12); vein Mi absent except 

 distal portion, r-m crossvein present, straight, nearly reachmg M4, 

 m-cu crossvein strong, M2 long, reachmg wmg margin; squama trans- 

 parent, margin concolorous, halter knob black, stem white. 



Abdomen long, narrow, distinctly arched with large dorsomedian, 

 bituberculate swellings on tergites ii-iv (pi. 5, fig. 26) ; tergites i-ii 

 mostly browaiish black, with faintly indicated posterior white fasciae; 

 tergites iii-v with hregular brown and white pattern, rather similar 

 to that shown by Sack (1936, fig. 8), the tubercles mostly brown as is 

 anterior margin of each tergite, creamy white markmgs dominate 

 laterally and behind; dorsum along midline including tubercles 

 covered with long white silky pile, each hair somewhat browned at 

 base, large lateral area with short, whitish yellow pubescence; sternites 

 mostly dark brown with narrow posterior white fasciae, ii-iii with 

 large white lateral spots, entire sternum covered with short white 

 pile except for bare i. 



Genitalia (pi. 6, fig. 31) minute, light brown, cercus nearly white 

 in spots; aedeagus long, thin, with definite apical notch (pi. 9, fig. 54) ; 

 ejaculatory apodeme small, narrow, with "wings" indistinct, "wing- 

 spread" about equal to greatest width of aedeagus. 



Discussion: Apparently this species is still known only from the 

 unique female type. For this reason the above description of the 

 male seems necessary, though it is possible that the male described 

 above is actually another closely related species. Such distinctive 

 features as the tuberculate abdomen, and possibly different wing 

 venation were not found m the female, but the former feature is 

 true m many species of the genus, while the latter character is usually 

 vague in descriptions. 



The male genitalia and tuberculate abdomen of hirtus suggests a 

 relationship to guttatus; however, the long body pile, two or more 

 antennal setae, and male genitalic structures show it belongs in the 

 colei group. Judging from its original description hirtus may be 

 related to formosus Loew.
