the length of the pronotum. Pronotuin rather stout, the greatest 

 width at the supra-coxal dilations, the shaft about three times the 

 length of the collar; anterior margin evenly rounded, posterior mar- 

 gin subtruncate; lateral portions very slightly expanded, and evenly 

 decreasing in width both anteriorly and posteriorly from the supra- 

 coxal portion; lateral margins feebly denticulate, more apparent 

 anteriorly; lower face of the slight lateral expansions punctate and 

 coriaceous ; median carina moderately distinct on the shaft. Tegmina 

 broad, coriaceous except immediately along the sutural margin and 

 the central portion of the median half of the interspace between the 

 principal branches of the ulnar vein; costal margin evenly arcuate, 

 except the apical third, which is diagonally emarginate ; apex narrowly 

 rounded; ulnar vein with three principal rami; stigma elongate-ovate. 

 Wings of moderate length, equalling the apex of the tegmina when at 

 rest; costal margin straight, except in the apical third, where it 

 curves posteriorly to the subangulate apex; anterior ulnar vein with 

 three distinct and equally disposed rami. Abdomen moderately broad, 

 the apex of the subgenital plate visible beyond the tips of the closed 

 tegmina and wings. Supra-anal plate transverse, narrow, the apical 

 margin slightly arcuate, the apex with a very shallow and almost 

 imperceptible emargination. Cerci attenuate, moniliform, slightly 

 exceeding the subgenital plate in length. Subgenital plate very broad, 

 apex strongly compressed, rostrate. Anterior coxse not quite equal 

 to the shaft of the pronotum in length, superior margins, particularly 

 the internal, denticulate, inferior margin with a series of rather large 

 spines, which decrease in size distally and also take on an alternating 

 large and small character ; femora about equal to the shaft of the pro- 

 notum in length, apical genicular lobes considerably developed and 

 armed apically with a slight, blunt, dentiform process, external in- 

 ferior margin with four strong dentiform spines, discoidal spines four 

 in number, internal inferior margin with a series of fifteen alternating 

 large and small spines, the margin with a vacant distal diastema; 

 tibiae (without apical claw) about half the length of the femora, external 

 margin bearing eleven or twelve spines, internal margin armed with 

 fourteen spines ; metatarsi considerably exceeding the remaining tarsal 

 joints in length and almost equal to the tibiae without apical claw. 

 Genicular spine of median and posterior femora rather small; meta- 

 tarsi of the median limbs very considerably less than the remaining 

 tarsal joints, posterior limbs with the metatarsi, but slightly shorter 

 than the remaining tarsal joints. 



General color pea-green, of the most brilliant hue on the tegmina.
