ately arcuate; transverse sulci two in number, the cephalic placed 

 about the cephalic third, the caudal placed immediately caudad of 

 the middle, margins of the pronotum non-tuberculate; lateral 

 carinae indicated by lines of low tubercles, which gradually converge 

 to the caudal transverse sulcus, then more abruptly diverge to the 

 caudal margin; lateral lobes with the greatest depth contained one 

 and two-thirds times in the length of the lobes, ventral margin slightly 

 sinuato-emarginate caudad, ventro-caudal angle slightly obtuse; 

 surface of the dorsum and the lateral lobes of the pronotum 

 shagreened. Tegmina subequal to the pronotum in length, broad 

 ovate in form, the width two-thirds of the length, the extreme portion 

 of the broadly rounded apex faintly truncate. Supra-anal plate 

 trigonal with a distinct medio-longitudinal impression; cerci brief, 

 acuminate; subgenital plate with the distal margin rectangulate 

 emarginate mesad; ovipositor subequal to the length of the prono- 

 tum and tegmina together, moderately arcuate, tapering, ventral 

 margin serrulato-denticulate on the distal fourth. Cephalic femora 

 very slightly longer than the length of the head and pronotum 

 together, unarmed on the ventro-caudal margin, with three spines 

 distad on the ventro-cephalic margin; cephalic tibiae unarmed dorsad, 

 on the ventral margins with five (caudal) to six (cephalic) spines. 

 Median femora very slightly longer than the cephalic femora, armed 

 on the ventro-cephalic margin with two to three spines, unarmed on 

 the ventro-caudal margin; median tibiae unarmed dorsad, ventro- 

 caudal margin with four to five spines, ventro-cephalic margins with 

 five to seven spines. Caudal femora about three times as long as the 

 tegmina, moderately robust, considerably inflated proximad, ventro- 

 cephalic margin with four decided distal spines, ventro-caudal margin 

 unarmed; caudal tibiae slightly exceeding the femora in length, well 

 spined. 



General color raw umber, becoming burnt umber on the dorsum of 

 the head and pronotum, the tegmina walnut brown. Head with the 

 face and portions of the genae straw yellow; a narrow postocular line 

 naples yellow; eyes tawny ochraceous; antennae distad of the second 

 joint tawny. Pronotum with the postocular line of the head con- 

 tinued caudad over the tuberculations of the pronotum as narrow lines 

 of naples yellow. Ovipositor with the margins and apex washed 

 with burnt sienna. Cephalic and median femora ferruginous, 

 becoming darker distad; cephalic and median til)i8e vinaceous-cinna- 

 mon, rather darker proximad. Caudal femora ferruginous, slightly 

 darkened distad, spines yellowish with the tips burnt sienna; caudal
