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

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.
