which portion it is of moderate width, subequal, becoming weaker 

 toward the clypeal suture, the portion ventrad of the ocellus sul- 

 cate; lateral facial carinse slightly arcuate and divergent dorsad, 

 subparallel ventrad; eyes moderately prominent in both sexes, the 

 length considerably (male) or slightly (female) greater than that of 

 the infra-ocular portion of the genae, subovate in outline; antennae 

 about equal to the head and pronotum in length, thick, slightly de- 

 pressed proximad, apex blunt. Pronotum with the cephalic margin 

 bearing a broad shallow median emargination, caudal margin obtuse- 

 angulate, the immediate angle very blunt, the sides of the same 

 slightly sinuate; median carina very low and weak, severed by three 

 transverse sulci, the caudal of which is deeper than the others; 

 metazona about two-thirds the length of the prozona, lateral angles 

 broadly rounded except for a slight shoulder on the metazona; 

 lateral lobes longer than deep, ventral margin obtuse-angulate, 

 sinuate cephalad. Tegmina exceeding the apex of the abdomen in 

 both sexes, in the male by the length of the pronotum, in 

 the female by hardly more than that of the metazona, 

 rather narrow, subequal, apex rounded, costal lobe small, 

 no distinct intercalary vein. Prosternal spine slightly 

 31 _ transverse, conic, acute; interspace between the meso- 

 joDACRis sternal lobes slightly longitudinal (male) or subquadrate 

 ruRciLLA- (female) ; metasternal lobes subcontiguous in both sexes.

APEXOF . . 



MALE AB- angulate in the remainder, the lateral margins strongly 

 thickened and inflated proximad, a distinct medio-longi- 

 tudinal sulcus present on the proximal half, this portion 

 being divided from the distal by a low obtuse-angulate trans- 

 verse carina, the distal section strongly arcuate in section, bear- 

 ing mesad a pair of small teat-like nodes; cerci of the male heavy, 

 elongate, reaching to the apex of the subgenital plate, the whole 

 compressed, the proximal half subequal, the remainder tapering 

 from the middle to the tip, which is abruptly bent inward at about 

 three-fifths the length of the cercus, the dorsal margin bearing a 

 short tooth-like process at about the point of flexure, from which 

 to the base the margin is keeled; subgenital plate conic, the apex 

 slightly blunt when seen from the side. Ovipositor jaws of the 

 female very slightly and weakly serrate. Cephalic and median limbs 

 of medium size, the femora of the male slightly inflated. Caudal 

 femora quite robust, the length about one and one-half times that 

 of the head and pronotum together, the greatest width contained 

 about three times in the length of the femur, pagina regularly and 

 closely patterned; caudal tibise with seven spines on the external
