with a short, narrow, hyahne streak directed backward from just 

 apicad of the end of the postmarginal vein and reaching a httle 

 caudad of the end of the stigmal vein; marginal vein punctiform, 

 stigmal longer than the postmarginal (fig. 5). 



In Doctor Ashmead's classification of the tribe ^ this genus would 

 run to Zarhopalus, a genus which does not have the foliaceous anten- 

 nae and which has the postmarginal and stigmal veins greatl}^ elon- 

 gated, the lateral ocelli distinct 

 from the margin of the e3'e and 

 nearer to the anterior ocellus 

 than to each other. 



In general appearance this 

 genus most resembles Cerapte-

the antennae segmented and the marginal vein elongate, in addition to
