90 PROCEEDINGS OF THE ACADEMY OF [March, 



interocular space very narrow, less than half the width of the narrow- 

 est portion of the fastigium; interantennal portion of the frontal 

 costa distinctly but not greatly produced, rounding into the fas- 

 tigium, somewhat expanded, not sulcate or punctate, costa for a short 

 distance dorsad and ventrad of the ocellus narrow and sulcate, 

 costa not present ventrad of this portion; face rugoso-punctate, 

 moderately retreating when viewed from the lateral aspect, lateral 

 facial carinse not sharply defined, converging dorsad; eyes large, 

 subovate, moderately prominent; antennae slightly shorter than 

 the pronotum, thick, slightly depressed. Pronotum nearly twice 

 as long as the exposed portion of the head, the greatest caudal width 

 of the whole pronotum nearly equal to the length; cephalic margin 

 slightly arcuate with a distinct but shallow median emargination, 

 caudal margin rounded obtuse-angulate ; three transverse sulci 

 deeply impressed on the dorsum and the caudal two as distinctly 

 indicated on the lateral lobes which they cross almost to the ventral 

 margin; median carina absent, lateral carinse indicated only as 

 raised welts which are traversed by all the sulci and bear a different 

 coloring from the remainder of the pronotum, dorsum strongly and 

 closely punctate; lateral lobes with the extreme dorsal length some- 

 what greater than the depth, ventral margin distinctly sinuato- 

 emarginate cephalad, ventro-caudal angle broadly rounded. Tegmina 

 about three times as long as the head, narrow, arched and over- 

 lapping, completely covered with numerous very small impressed 

 areolae; costal margin straight except for a slight proximal expansion, 

 sutural margin very slightly arcuate, apex obliquely rotundato- 

 truncate, principal veins alone apparent. Wings reaching to the 

 tips of the tegmina. Prosternal spine very short, thick, strongly 

 transverse, blunt. Interspace between the mesosternal lobes 

 slightly transverse and very slightly broader than the lobes them- 

 selves; interspace between the metasternal lobes trigonal, strongly 

 narrowed caudad. Cephahc and median limbs rather short. Caudal 

 femora about twice as long as the pronotum, robust, inflated, the 

 greatest thickness being about two-thirds the depth, which latter 

 is contained three times in the length, carinse serrato-dentate, par- 

 ticularly the medio-dorsal, pagina with a well-marked and regular 

 pattern impressed by punctations, genicular extremity large, genicu- 

 lar lobes broad; caudal tibise about four-fifths the length of the 

 femora, armed on the external margin with seven spines, one of which 

 is apical, and with six on the internal margin; tarsi about three- 

 fourths the length of the tibise, slender, second and third joints 

 subequal and each longer than the first joint.
