of slightly more conical tubercles: shaft at cephaUc third with a 

 median bifid tubercle, the points of which are conical, immedi- 

 ately caudad of this is a pair of widely separated, low, conical tuber- 

 cles, and about an equal distance from this pair, but on each lateral 

 face of the shaft, is a pronounced conical tubercle, caudad of which 

 and running dorso-caudad is a carinate ridge, stronger caudad, 

 and fusing with a strumose area near the caudal margin, where 

 there is a pair of elevated, longitudinally disposed projections, 

 the crests of which are serrulate; median carinulation distinct but 

 low caudad of the median paired tubercle on the collar; when seen 

 from the side the region of the expansion is distinctly sellate, and 

 the shaft less decidedly but still distinctly so. 



Tegmina four and one-third times as long as the pronotum, its 

 greatest width contained three and one-half times in the tegminal 

 length, the greatest width at the distal third: costal margin appreci- 

 ably ciliate, very briefly arcuate proximad and in distal third moder- 

 ately arcuate to the rotundato-rectangulate apex, distal margin 

 suturad of the apex broadly rounding into the sutural margin: mar- 

 ginal field coarseh^ reticulate; discoidal vein bifurcate at distal fourth; 

 median vein bifurcate at middle; ulnar vein bifurcate near the base, 

 the sutural ramus bifurcate immediatelj^ distad of the primary bifur- 

 cation, all rami of the median and ulnar veins reaching the sutural 

 margin; anal vein arcuate in proximal half, thence straight oblique; 

 axillary veins two in number, the sutural one bifurcate near its base; 

 stigma distinct, slightly oblique, involving all veins from the median 

 to the caudal ramus of the ulnar vein ; areas between all veins of the 

 discoidal field irregularly but rather openly and finely recticulate with 

 cross-veins, which are less numerous in the immediate vicinity of 

 the main veins than in the middle of the areas. Wings when in re- 

 pose surpassing the apices of the tegmina by about the length of 

 the collar of the pronotum, the apex rotundate-rectangulate : ulnar 

 vein biramose, the proximal ramus diverging near the proximal 

 third, the distal ramus diverging at about the distal third, the 

 proximal ramus separated from the distal one by a considerable 

 space, which narrows distad: discoidal field of the wing with the 

 interspaces between the veins proximad with fairly regular cross- 

 veins, which are much more oblique in some areas than in others, 

 distad the cross-veins become irregular and anastomosing, except in 

 the narrower fields where there is a general biseriate disposition. 



Abdomen with the supra-anal plate transvei'se, triangularly pro- 

 duced mesad, moderately tectate, weakly carinate mesad, the apex
