of so few have been reared that we are unable to find the limits of 
variation and to definitely associate the sexes. It is quite possible 
that some of the females placed in this genus may have to be located 
elsewhere when the two sexes are known.

The palpi are more or less reduced and in most species are uni- 
articulate or biarticulate (fig. 44a). The wings are long and narrow, 
the third vein usually joining the margin at or beyond the apex 
(pl. 14, figs. 2-4). The claws (fig. 41) are long, stout, evenly curved, 
mostly simple and the pulvilli are greatly reduced in many species, 
specially in the males. The male genitalia are heavy, the basal clasp 
segment being stout while the terminal clasp segment is usually ob- 
tuse and with a more or less rudimentary spur. The dorsal plate is 
broadly emarginate while the ventral plate is usually short and 
relatively broad. The ovipositor of the female is short and with 
broad terminal lobes.
