 slightly (female) constricted ventrad of the ocellus, the ventral portion 

 subequal, sulcate ventrad of the interantennal region, punctate dorsad, 

 biseriate in the female, irregularly in the male; supplementary facial 

 cariiite prominent, moderately divergent arcuato-convex; eyes quite 

 (male) or moderately (female) prominent, sub-ovate in outline, the 

 length about twice 

 that of the infra- 

 ocular portion of 

 thegenae; antennae 

 about one and one- 

 third times the 

 length of the head 

 and pronotum, 

 slightly heavier in 

 the male than in the 

 female. Pronotum 

 very slightly sellate, with the greatest dorsal width of the diskcontained 

 about one and one-half times in the length of the same; cephalic 

 margin arcuate, caudal margin rounded obtuse-angulate; median 

 carina ver}" low, hardly appreciable on the prozona in the male, 

 apparent cephalad on that portion in the female, present though 

 very weak on the metazona in both sexes, lateral angles very broadly 

 rounded, a slight shoulder on the metazona; transverse 

 sulci three in number; metazona about two-tliirds the 

 length gf the prozona; lateral lobes with the dorsal length 

 greater than the depth, ventral margin obliquely arcu- 

 ato-truncate caudad, considerably sinuato-emarginate 

 cephalad, ventro-cephalic angle marked, slightly obtuse, 

 ventro-caudal angle rounded broad obtuse. Tegmina 

 slightly (female) or considerably (male) surpassing the 

 apex of the abdomen, very (male) or moderately (female) 

 narrow, subequal, apex lanceolate. Wings ample. Pros- 

 ternal spine slightly compressed, very low and blunt; in- 

 terspace between the mesosternal lobes longitudinal, 

 moderately (female) or decidedly (male) constricted me- 

 sad, making the interspace hour-glass shaped ; metaster- 

 nal lobes contiguous. Abdomen somewhat (female) or 

 decidedly (male) compressed; supra-anal plate of the male moder- 

 ately lanceolate; cerci of the male simple, styliform, reaching about 

 to the apex of the subgenital plate; subgenital plate short, slightly 

 compressed, blunt, the apical margin arcuate when seen from the 

 side; ovipositor jaws of the female rather elongate, compressed. 

 Cephalic and median limbs very short. Caudal femora falling
