This genus comprises a number of very distinct forms easily 

 separable from Contarinia, to which they are closely related, by 

 the broad wings. These organs have a conspicuous, broadly rounded 

 extension posteriorly, the width being about two-thirds the length 

 (plate 6, figs. 5-7). The antennae of the male are peculiar in

Fig. 18 Toxomyia rubida, tip of abdomen and 

 ovipositor of female (enlarged, original) 



that the basal portion of the stem on the flagellate segments rarely 

 has a length equal to its diameter. The enlargements are relatively 

 large, subglogose, and the circumfili rather short, stout and uniform. 



The female has relatively narrow wings, with a length about 

 twice the width and almost subsessile antennal segments, the stem 

 of the fifth being about one-fourth the length of the basal enlarge- 

 ment. There are two low circumfili, the distal filum forming small 

 apical loops. The ovipositor is stout, about one-half the length 

 of the abdomen and with a moderately long terminal lobe not 

 constricted basally.
