caudal portion and becoming subobsolete on the occiput; angle of 

 thefastigium and face rounded obtuse; lateral foveolse trigonal, rather 

 large, moderately excavate; frontal costa as a whole rather broad, 

 moderately and regularly expanding from the distinct fastigio-facial 

 division to the ocellus, below which it is slightly constricted then 

 moderately expanded to the clypeal suture, sulcate throughout except 

 close to the clypeal suture; eyes reniform-elliptical, slightly prominent, 

 somewhat exceeding the infraocular sulcus in length; antennae 

 distinctly less than the head and pronotum in length. Pronotum 

 with the median carina moderately elevated, rather uniform in height, 

 although the section on the metazona is a trifle lower than that on the

prozona, the incision being well marked and rather broad; lateral 

 carinse marked, regularly divergent caudad, the space separating 

 them caudad half again as much as that cephalad, the carinas being 

 sinuate for a short distance on the caudal portion of the prozona; 

 cephalic angle of the disk broad obtuse, caudal angle of the disk 

 slightly obtuse with the angle narrowly rounded; 

 lateral lobes deeper than long, slightly narrowing 

 ventrad, the ventral margin considerably sinuate 

 cephalad. Tegmina very slightly surpassing the 

 tips of the caudal femora; intercalary vein with 

 the proximal half nearer to the ulnar vein, the distal 

 half equidistant between the ulnar and median 

 veins. Interspace between the mesosternal lobes 

 strongly transverse ; interspace between the metaster- 

 nal lobes quadrate. Caudal femora considerably 

 inflated, the greatest width being about one-third 

 the length; pattern of the pagina well impressed 

 and regular, the expansion of the ventral carinas 

 slight; caudal tibiae with nine to ten spines on the 

 external margins.
