being equal to two-thirds the fastigial length; fastigium i)rominent, 

 slightly ascending, the dorsal length equal to the exposed portion 

 of the occiput, when seen from the dorsum evenly tapering to near 

 the apex which is very bluntly rounded, a distinct medio-longitudinal 

 depression present in the distal half, when seen from the side the 

 angle of the fastigium is acute-angulate with the immediate angle 

 narrowly rounded; face strongly retreating to the ocellus, thence 

 very slightly so ; frontal costa continuous, distinct ; sulcate through- 

 out its length, greatly compressed at its junction with the fasti- 

 gium, thence very gradually widening to the clypeal suture; lat- 

 eral facial carinse very prominent, slightly diverging ventrad; eyes 

 very prominent, large, ovate in outline, the length about equal to 

 that of the infra-ocular portion of the genae; antennae about twice 

 the length of the head and pronotum, joints elongate, strongly 

 depressed proximad and decidedly ensiform, tapering to the slender

and moderately acute apex. Pronotum with the greatest dorsal 

 width contained about twice in the length; cephalic margin arcuato- 

 emarginate, caudal margin acute-angulate; median carina repre- 

 sented by a thread-like trace, the dorsum with a slight depression on 

 the cephalic portion of the metazona, lateral angles inflated and 

 covered with numerous blunt spiniform tubercles, the tubercles 

 being present on the entire length of the angles but the distinctly 

 inflated characi^er is limited to the metazona; lateral lobes with the 

 greatest length distinctly exceeding the depth, ventral angles obtuse, 

 ventral margin broadly rounded obtuse-angulate, the prozonal por- 

 tion of the lobes with a diagonal blunt ridge extending ventro-cephalad 

 to the ventro-cephalic angle, ending in a small blunt tubercle. Teg- 

 mina exceeding the apex of the subgenital plate by about the length 

 of the pronotum, elongate, subequal, the greatest width contained 

 about five and one-half times in the length; costal margin distinctly
