from lepidus it also differs in the dull olivaceous caudal tibiae and 

 tarsi. 



Size medium; form very elongate; surface of the pronotum and 

 pleura scabroso-punctate, of the abdomen shiny. Head with the 

 dorsal length about four-fifths that of the dorsum of the pronotum; 

 occiput slightly arched, not elevated, interocular space nearly two- 

 thirds the greatest width of the fastigium; fa.stigium acute-angulate, 

 plane, angle when seen from the side rotundato-truncate ; face very 

 considerably retreating; frontal costa distinct only to a short dis- 

 tance ventrad of the ocellus, appreciably constricted immediately 

 ventrad of the ocellus and faintly so dorsad of the same point, de- 

 cidedly depressed within its margins; eyes elongate ovate, longer 

 than the infraocular portion of the gense, moderately prominent 

 when viewed from the dorsum; antennae distinctly but not greatly 

 longer than the head and pronotum, somewhat ensiform, the expan- 

 sion almost wholly in the five proximal joints, the distal half tapering 

 almost imperceptibly, the apex somewhat blunt. Pronotum with 

 the greatest caudal width of the disk contained one and two-thirds 

 times in the length; cephalic margin truncato-arcuate, caudal margin 

 very slightly obtuse-angulate, median carina present only on the 

 metazona where it is but little elevated, transverse sulci three in 

 number, metazona contained one and one-half 

 times in the prozona; lateral lobes slightly longer 

 than deep, ventral margin arcuato-emarginate 

 cephalad, truncate caudad, caudal angle bluntl}' 

 rectangulate. Tegmina about five times the 

 length of th-e pronotum, subequal in width, 

 the latter being about two-thirds the dorsal 

 length of the pronotum; costal margin consider- 

 ably arcuate in the distal third, sutural margin 

 nearly straight, apex narrowly rounded; inter- 

 calary area without any longitudinal vein. 

 Prosternal process transverse, constricted mesad, 

 the apical portion somewhat compressed, sub- 

 fusiform and the lateral processes blunt; inter- 

 space between the mesosternal lobes very narrow; 

 metasternal lobes contiguous. Cephalic and 

 median limbs short, rather slender. Caudal 

 femora slightly more than half the length of the 

 tegmina, compressed, rather regularly tapering, 

 the greatest width contained about five and one-half times in the
