ocular sulcus; antennae subdepressed, the apex more so than the proxi- 

 mal and median portions and very slightly expanded. Pronotum 



with the median carina considerably elevated, 

 subcristate, not or slightly arcuate cephalo- 

 caudad, the intersection of the principal sulcus 

 being very appreciable, though not deeply 

 severing the crest; lateral carinac irregular, 

 composed chiefly of tubercles, broken mesad; 

 cephalic margin of the disk obtuse-angulate, 

 caudal margin of the disk rectangulate to 

 slightly acute-angulate; lateral lobes with the 

 greatest depth about equal to the greatest 

 length. Tegmina surpassing the tips of the 

 caudal femora by about the length of the head, rather broad, obliquely 

 rotundato-truncate at the apex; intercalary vein proximad very close 

 to the ulnar vein, mesad equidistant from the ulnar and median veins. 

 Interspace between the mesosternal lobes subquadrate in the male, 

 slightly transverse in the female; metasternal lobes with an extremely 

 narrow interspace in the male, the interspace subquadrate in the 

 female. Caudal femora more robust in the female than in the male, 

 the greatest width contained three and one-half times in the length in 

 the male, three times in the female. 



Green Phase. — Head, pronotum, pleura, caudal femora, a longitudinal 

 bar on the medio-proximal portion of the tegmina, a 

 median, and a costal premedian patch on the same 

 apple-green ; remainder of tegmina and venter 

 brownish, the venter inclined toward raw umber, 

 the sutural half of the tegmina mars-brown with a 

 pattern of obsolete darker maculations, blending 

 into the clove-brown areas on the costal half of the 

 tegmina. Dorsum of the caudal femora marked 

 with median, premedian and preapical patches of 

 clove-brown, the median the largest and triangular 

 in shape, the markings being placed in juxtaposition 

 to clove-brown areas on the tegmina; ventral faces 

 of the caudal femora black with two whitish bands, 

 one median and the other preapical, genicular region 

 clove-brown; caudal tibiae glaucous, the genicular 

 extremity clove-brown with a patellar spot of pale greenish and a 

 broad complete yellowish-white annulus, spines yellowish with black 

 tips; caudal tarsi pale ochraceous. Caudal margin of pronotal disk
