tion ; complete transverse sulci three in number, the caudal one 

 placed close to the caudal margin, the cephalic sulcus distant from the 

 cephalic margin a distance equal to the space from the second sulcus 

 to the caudal margin, interspaces between the first, second and third 

 sulci subequal dorsad; lateral lobes much deeper than long, cephalic 

 and caudal margins subparallel, ventral margin rotundate, emarginate 

 cephalad. No tegmina or wings present. Exposed portion of the 

 mesonotum less than half as long as the metanotum; median carina on 

 both segments marked as on pronotum. Abdomen very slightly com- 

 pressed, distinctly but slightly carinate. Ovipositor jaws rather blunt. 

 Presternum with a low quadrate process with blunt slightly produced 

 angles. Mesosternum and metasternum distinctly concave. Cephalic 

 femora slightly bowed, inflated, with several depressed areas on the 

 caudal face, and a distinct carina on the superior portion of the cephalic 

 face, cephalic genicular lobe more produced and rotundate than the 

 caudal one; tibiae equal in length and but slightly slenderer than the 

 femora, straight; terminal tarsal joint very distinctly exceeding the 

 basal two in length. Median femora about equal in the length to the 

 cephalic femora, compressed, several slight or irregular carinse present, 

 cephalic genicular lobe large and rotundate, caudal genicular lobe ver}^ 

 slight and little more than a cingulum ; tibise and tarsi as in the cephalic 

 limbs. Caudal femora not reaching to the apex of the abdomen, about 

 four and one-half times as long as the greatest Avidth, compressed, mar- 

 gins regularly but slightly arcuate, pregenicular constriction slight, 

 carina distinct, the median dorsal slightly serrato-dentate, pattern of 

 the pagina distinct but flattened and with little relief, genicular arch 

 rather low, genicular lobes rectangulate apically with the ventral mar- 

 gin rotundato-sinuate ; tibiae slightly shorter than the femora, lateral 

 margins with seven rather blunt spines, including the apical one, inter- 

 nal margins with ten spines including the apical one; metatarsus and 

 terminal tarsal joint subequal in length, second joint distinctly shorter 

 than the others, the whole tarsus about half the length of the tibia. 



General color cinnamon, eyes russet. iMargins of the pronotum, and 

 caudal margins of the metanotum and basal abdominal segments nar- 

 rowly washed with a more or less distinct blackish-brown suffusion. 

 Median limbs dull brownish caudad. Caudal femora marked along the 

 lateral and median carinae and on the whole genicular faces with black- 

 ish-brown; dorsal portion of the genicular region ochre yellow distad, 

 caudal face of the caudal femora blackish except for a narrow ochre 

 yellow edging to the genicular region. Caudal tibiae and tarsi cephalad 

 vinaceous-cinnamon, caudad dragon's blood red, spines with a small
