anterior margin of the autennal scrobe to the ends of tlie epicranial 

 suture and is so directed at its upper end that it would if continued far 

 enough pass into the groove which separates the lateral from the sub- 

 median lobes of the vertex ; the facial shield has not shared in the widen- 

 ing of the head, a wide space intervening between it and the eyes ; it 

 may be described as a transversely elongated rectangular plate giving off 

 a broad tongue-shaped process from its upper or basal margin, or as a 

 broad isosceles triangle tlie two adjacent equal sides of which are deeply 

 indented by the antennal scrobes. The eyes are compressed and some- 

 what drawn oat superolaterally, where they bear a huge straight slender 

 conical non-faceted spine. Stemmata large on a prominent cuboidal 

 frontal eminence. 



Prothorax very greatly elongated, as long as the abdomen to the 

 middle of the sixth segment. Pronotum with its lateral margins granu- 

 lose, becoming spinulose in front, deflexed in the posterior, nearly 

 horizontal in the anterior lobe, which is bent np at an obtuse angle to 

 the postei'ior lobe, is transversely convex, bears a few tubercles on each 

 side of the middle lino, and presents on its posterior enlarged end 

 a broad and shallow longitudinal depi-ession, which is continuous with a 

 similar one on the enlarged anterior end of the posterior lobe, which 

 is higher than broad, so strongly compressed as to be veiy steeply roof- 

 shaped, and, with the sternal region, so strongly arched as to have tho 

 form of a bow, being concave ventrally and correspondingly convex 

 dorsally, where it is surmounted by a blunt rather ill-defined raised line, 

 on which, especially anteriorly, where some are collected into a small 

 clump deforming the surface, are a few small mammilliform tubercles, 

 and which at tho 9 broadly truncate-rotundate, cf triangularly pro- 

 duced (?), posterior end gives off a very narrow spir.ally coiled leathery 

 process. 



Mesonotum, metanotum, and seg. med. with a very strong 

 raised dorsal line, which is continued decreasingly to tho end of the 

 4th abdominal tergum, where it ends to begin again at the anterior end 

 of the fifth tergum to be continned increasingly to the last. 



The abdomen is of uniform width to tho 6th segment, thence tapoi'- 

 ing in slightly arched outlines to its rounded extremity ; all its terga 

 bear in the middle line posteriorly a fringed cup-shaped foliaceous lobe 

 the upper lip of which terminates in a delicate recurved filament, and 

 which in the 5th and 6th is large, in the 5th very large, and conspicu- 

 ous ; 9 sterna 2-6 with subequal foliaceous sub-quadrant-shaped dupli- 

 catures of the integument at middle of hinder margins ; 10th tergum 

 Bemioval, roof-shaped, 1^ times as broad as long. Ceroi foliaceous, 

 lanceolate, divided at the extremity by a deep notch into two sharp points, 

 extending by more than two-thirds of their length__beyond tho abdomen.
