 half \vidth of mandible from base of latter; eyes very shallowly convex, 

 as long as width of face, parallel; postocellar line slightly longer than 

 locellocular line and nearly twice as long as diameter of a lateral 

 ocellus; antenna rather stout, tapering but not attenuate toward apex, 

 46- to 50-jointed, basal joint of flagellum about four times as long as 

 thick at apex, second barely twice as long as thick, middle joints as 

 thick as long.

Legs stout, hind femur hardly six times as long as deep, barely 

 two-tliirds as long as tibia; inner hind calcarium more than half 

 basitarsus; tarsus stout, apical joint nearly as long as third; claws, 

 especially front and middle ones, strongly pectinate. 



Wings: Apical abscissa of radius moderately curved at base, much 

 less than twice as long as basal abscissa ; areolet somewhat irregular, its 

 apical angle rather sharply acute; second discoidal cell rather broad, 

 basal abscissa of subdiscoideus hardly a half longer than second recur- 

 rent, the latter strongly curved above ; nervulus distinctly postf ureal ; 

 abscissula twice as long as intercubitella. 



Abdomen stout, weakly compressed at apex; first tergite strongly 

 depressed throughout, much more than half as broad as long, second 

 not or barely as long as broad at base; ovipositor straight, sheath 

 distinctly shorter than first tergite. 



Ferruginous with face, clypeus, mandibles, malar space, indefinite 

 markings on anterior margin of mesoscutum, scutellum, and tegulae 

 more or less distinctly j^ellowish; occiput, stemmaticum, thoracic
