suliquadrate, the distal margin shallowly emarginate, in profile the caudo- 

 latcral angles of the plate are broadly rounded rectangulate; surface of plate 

 compressed i)roximad with a distinct lamellato-carination mesad in that re- 

 gion, distad with a median sub-deplanation. Seventh sternite with a decided, 

 conical, non-compressed tubercle, which is weakly hooked caudad. 



Cephalic femora with five spines on the ventro-cephalic margin, seven to 

 eight in number on the ventro-caudal margin; cephalic tibiae with four spines 

 on the dorso-caudal margins. Median femora with five to six spines on 

 ventro-cephalic margin and seven spines on ventro-caudal margin. Caudal 

 femora slightly shorter than the combined length of head, pronotum and 

 tegmina, ventro-external margin with ten to eleven spines, ventro-internal 

 margin with eight to nine spines. 



The coloration features here given have I)een taken only from the Itest 

 preserved specimens. 



General coloration of head, thorax, venter and limbs between deep chryso- 

 lite green and rainette green (Ridgway), becoming biscay green on the teg- 

 minal venation, the face with a weak ochraceous tinge. Eyes russet; an- 

 tennae with the two proximal segments of the general color, remainder russet 

 paling to buckthorn brown distad, on proximal fifth the russet segments 

 individually are darkened distad, and occasionally the dorsal surface, when 

 the antennae are extended cephalad, is completely blackish infuscate for a 

 considerable distance. Mandibles with their internal face generally washed 

 with bay; clypeus occasionally infuscate distad with bay. Pronotum with 

 entire cingulate margin pencilled with blackish fuscous, except in contact 

 with the pale area on the lateral lobes, where the margin is of the general 

 color, the dark margining of greatest width cephalad on disk: opaque white 

 maculations developed as a rather broad intermarginal bar caudad on the 

 lateral lobes, also as a pair of elongate trigonal spots caudad on the inflated 

 caudal section of the pronotal disk, the apices of which spots are directed 

 toward the median line and are occasionally subcontiguous, but generally 

 well separated by a median fuscous patch, which in the extreme intensive 

 type completely encircles the dorsal white patches, the latter being severed 

 from the lateral patches by a similar dark patch, which in these intensive 

 individuals is connected with the median fuscous patch. In extremely in- 

 tensive specimens the fuscous extends ventrad along the cephalic margin of 

 the lateral white patch and marks a sharp contrast. Meso- and metapleura 

 each with an opaque white patch, which is also indicated on their respective 

 coxae. Tegmina with the stridulating id") or axillary ( $) field largely, and 

 the greater portion of the distal section of the discoidal field with the mem- 

 branous portion mummy brown to fuscous, the entire venation pencilled 

 over this in biscay green to dull wax yellow, the dark base color in intensive 

 specimens showing through very solidly. Wings with the base color olive- 

 brown to clove brown, the greater portion of the surface with numerous 

 subquadrate patches of pale dull green-yellow, these coalescing about the 

 periphery to form there a nearly solid pale margin, the costal margin and 

 greater portion of the proximal section of the anterior field of the pale color.
