spines increasing in length distad ; cephalic tarsi subequal in length to- 

 the cephalic tibiae with claw, meta- 

 tarsus slightly exceeding the re- 

 maining tarsal joints in length. 

 Median and caudal limbs of the 

 usual type, but rather robust in pro- 

 portion. 



General color pale apple green, 

 the abdomen pale olive green, but 

 possibly this is due to discolora- 

 tion. Head with the upper face 

 inclined toward yellowish, eyes 

 olive. Tegmina with the base color 

 of the discoidal and anal fields 

 orange-ochraceous, the veins weak 

 olive buff, finely outlined with chest- 

 nut, the costal field and proximal 

 portion of the discoidal and anal 

 fields more or less uniformly deep 

 maroon, the veins of the costal field 

 outlined with pale salmon-buff, 

 those of the discoidal and anal 

 fields more olive buff. Proximal 



portion of the cephalic tibiae and distal portion of the cephalic femur 

 washed with chrome yellow. Cephalic femoral and tibial spines 

 ochre yellow tipped with seal brown.

Size small for the genus; form moderately elongate, but more 

 abbreviate cephalad than usual in this genus. Head slightly more 

 transverse than in the female, the occipital outline slightly less 

 arcuate; ocelli large, placed in a triangle; eyes more prominent. 

 Pronotum with the greatest width more than a third of the length, 

 general form of the pronotum similar to that of the male, but with the 

 margins entire or faintly crenulate instead of spinose; median carina 

 but very faintly indicated. Tegmina ample, considerably surpassing 

 the apex of the abdomen, the greatest width contained about four 

 times in the length of the same; hyaline, with the vicinity of the 

 humeral trunk coriaceous; costal margin arcuate proximad and 

 distad, straight for the remainder of the length, sutural margin
