fastigium; fastigium slightly declivent, the distal half acute-angu- 

 late when seen from the dorsum, 

 shallowly excavate, angle of the 

 fastigium when seen from the side 

 rounded rectangulate ; face slightly 

 retreating; frontal costa regularly 

 expanding to the clypeal suture, 

 moderately excavate, the margins 

 somewhat sinuate, face somewhat 

 scabrous; eyes subovoid, slightly y^g, 9-12.-Dorsal and lateral 

 longer than the infra-ocular por- views of the fastigium of Zygo- 

 tion of the gen^, moderately promi- *J'™» r^Z.S' ('^I'V&ffi^'J' 

 nent when seen from the dorsum. 11-12). (x 4.) 

 Pronotum somewhat inflated on 



the prozona, deplanate on the metazona. slightly tectate on the 

 prozona, the prozona somewhat elevated when seen in profile, 

 the metazona being rather straight and slightly less elevated; dorsum 

 of the pronotum slightly less than twice the dorsal length of the head, 

 cephalic and caudal margins obtuse-angulate, the former with the 

 angle sharp, the latter with it subtruncate and the sides of the angle 

 slightly emarginate; caudal width of the disk slightly more than two- 

 thirds the length; median carina distinct, rather high on the meta- 

 zona, blunt, cut by three transverse sulci, the metazona slightly 

 shorter than the prozona; lateral shoulders distinct on the metazona, 

 well rounded on the prozona; lateral lobes distinctly longer than deep, 

 the ventral margin with a slight oblique truncation cephalad; surface 

 of the entire pronotum strongly scabroso-punctate. Tegmina three 

 and a third times the length of the pronotum, reaching caudad of 

 the tips of the femora; costal margins moderately arcuate proximad 

 and distad, straight mesad, sutural margin nearly straight, apex 

 rather narrowly rounded; intercalary area with no distinct inter- 

 calary vein. Prosternal spine somewhat compressed, slightly 

 bulbous, and very much rounded longitudinally at the apex. Inter- 

 space between the mesosternal lobes distinctly longer than broad; 

 metasternal lobes separated by a wedge-shaped interspace which 

 at its narrowest point is subequal to the mesosternal interspace. 

 Cephalic and median limbs moderately robust, rather short. Caudal 

 femora falling slightly short of the tips of the ovipositor jaws, 

 tapering, rather slender; caudal tibiae with eight to nine spines on 

 the external margin, internal margin with twelve spines considerably 

 longer than those of the external margin.
