margin of the pronotum; occiput slightly arcuate longitu- 

 dinally, the caudal section of vertex with a pair of distinctly 

 impressed subpyrif orm areas ; interocular region sHghtly wider 

 than the fastigium, broadly and deeply sulcate ; f astigium very 

 greatly declivent, sulcate as in the interocular space, the sul- 

 cate portion, however, being slightly broader than between the 

 eyes; frontal costa somewhat narrower than the fastigium 

 dorsad, very gradually expanding ventrad to very near the cly- 

 peal suture, where the margins curve strongly laterad, sulcate 

 ventrad to immediately dorsad of the ocellus, where the sulcus 

 terminates abruptly, and from the ocellus ventrad it is present 

 shallower and sub-obsolete as the clypeal suture is approached ; 

 lateral foveolse lanceolate, trigonal, distinctly impressed; eyes 

 broad, somewhat depressed ovoid in outline, about equal in 

 length to the infra-ocular groove, moderately prominent when 

 viewed from the dorsum; antennae about equal to the dorsal 

 length of the head and pronotum ; ventral portion of head dis- 

 tinctly broader than the dorsal. Pronotum with the length of 

 the disk about half again the dorsal length of the head, and 

 with the greatest width of the disk but slightly shorter than the 

 length; cephalic dorsal margin very slightly obtuse-angulate, 

 caudal margin decidedly obtuse-angulate ; lateral angles of the 

 disk very distinct on the metazona and the cephalic portion of 

 the prozona, broken and sub-obsolete mesad; median carina 

 distinct, moderately elevated, straight, cut by the transverse 

 sulcus very slightly cephalad of the middle; lateral lobes dis- 

 tinctly deeper than long, the cephalic and caudal margins 

 obliquely emarginato-sinuate, ventro-caudal angle broadly 

 rounded. Tegmina exceeding the tips of the caudal femora by 

 slightly more than the length of the pronotum, moderately 

 broad, slightly narrowing distad, the apex obliquely rotundato- 

 truncate; intercalary vein prominent, through the greater 

 part of its length closer to the median than to the ulnar 

 vein. Wing with the greatest width contained one and 

 one-thirds times in the length, apex sub-rectangulate with the 

 distal portion of the costal margin arcuate. Mesosternal lobes 

 with the interspace very strongly transverse; interspace be- 

 tween the metasternal lobes transverse. Caudal femora robust, 

 the ventro-lateral carina distinctly lamellate, reaching its 

 greatest expansion at two-fifths the distance from the apex, 

 pattern of the paginae distinct; caudal tibiae slightly shorter 

 than the femora, armed laterad with seven spines.
