tinctly crenulate; posterior ocelli two-thirds as far from the 
eye as from one another. Antennae (Fig. Ic) slightly longer than 
the head and thorax; scape stout, curved; pedicel globose or 
but little elongated; flagellar joints of about equal length, all 
long and slender (probably the basal joints are slightly longer, 
but they cannot be viewed exactly in the proper plane). Meso- 
notum and scutellum shagreened; posterior edge of mesonotum 
straight, the suture not crenulate. Pleurae and coxae smooth or 
finely granulate; mesopleura with a crenulate line along the 
anterior and posterior edges. Abdominal segments of nearly

as long as the dorsal length of the sixth segment. Wings ample, 
the margins with the usual short fringe of hairs, but none of the 
veins appear to be bristly as in Dinapsis. Venation (Fig. la)
