than finel}' suleate: frontal costa less clearly defined ventrad and 

 with the sulcation weaker and sub-obsolete ventrad: eyes not quite 

 twice as long as the infra-ocular portion of the gense : antennae about 

 two and one-half times as long as the dorsum of the pronotum. Pro- 

 notum slightly shorter, the lateral lobes about one and one-half times 

 as long as deep. Mesonotum and metanotum with marginal form 

 and tuberculiform structure less decided. Supra-anal plate elongate 

 trigonal, strongly arcuate in transverse section, apex rather blunt, 

 surface non-sulcate: cerci short, blunt, styliform: ovipositor valves 

 exserted, elongate, straight, compressed, apices slightly blunted, 

 lateral margins rather finely denticulate, dorsal surface of dorsal 

 valves weakl}^ canaliculate. Interspace between the mesosternal 

 lobes slightly transverse: metasternal lobes narrowly separated. 

 Cephalic and median femora more slender. Caudal femora with 

 dorsal genicular spine less aciculate. 



General color calla green to ivy green, passing into more or less 

 clear oil yellow on the lateral lobes of the pronotum (cf ), the gense 

 and lower face (cf) and rostral region (both sexes). The pale spot- 

 ting ranges from maize yellow, through creamy white to light green- 

 yellow, and is distributed roughly as follows : three paired spots on face, 

 three to four paired markings ventrad of eyes and on gense, a paired 

 series of eight spots following the usual position of lateral pronotal 

 carinse extending from eyes to caudal coxse, another paired series 

 extending from mesonotum to and over dorsum of third to fifth proxi- 

 mal abdominal segments, ventral section of lateral lobes of pronotum 

 with three paired dashes; all these markings placed on strumose 

 tubercles or ridges. Fastigium of male distinctly, of female weakly, 

 pale lemon yellow: antennse of the color of the face, infuscated distad : 

 eyes mars brown to russet. Abdomen of male occasionally yellowish 

 disto-ventrad : furcula, edge of expansion of disto-dorsal abdominal 

 segment and tips of cerci of male black. Caudal femora with distal 

 extremity and adjacent section of tibia? cadmium orange to cadmium 

 yellow, strongest on the genicular arches and weakly tinged with the 

 general greenish on the lobes and dorsum: caudal tibiae with spines 

 black-tipped: caudal tarsi with pulvilli pads scarlet red in some speci- 

 mens, yellowish (possibly faded) in others.
