the segments of the same, and an adventitious medio-longitudinal 

 alidominal thread. The tone of this pattern varies from barita 

 yellow (in the recessive extreme where it is very poorly contrasted) 

 to buff yellow, in the generally greenish individuals running to 

 whitish with the transverse edgings of the abdominal segments cendre 

 •green. The abdominal infuscation varies in intensity with the 

 general condition of the coloration, in the extreme recessive condition 

 being absent and in the other extreme covering the entire dorsum of 

 the abdomen (except for the medio-longitudinal thread) and the 

 dorsal portion of the lateral faces of the same, between which types 

 •are regular graduations in the dorsal width of this shade, the lateral 

 patches decreasing in size toward the average and recessive condition. 

 The tone of this infuscation is always blackish. Eyes varying from 

 terra cotta to vandyke brown; antennae lightly more intense than 

 the general color. Pronotum with the pale borders of the lateral 

 lobes somewhat variable in width. Tegmina with the greater portion 

 of the anal field and much of the discoidal field with the base color 

 varying from wood l)rown to seal brown, the venation and a large 

 proximal patch on the anal field varying from sulphine yellow to raw 

 sienna, frequently more or less washed with greenish. Abdomen 

 with a dorsal medio-longitudinal bar of from sulphine yellow to 

 antique brown in those specimens approaching the intensive extreme 

 which have the dorsum of the abdomen not solidly infumate, the 

 anedio-longitudinal thread of the pale pattern of course dividing this 

 tbar; segments with the pale pattern edging narrowing mesad, 

 "broadest where they bisect the lateral bars of the same pattern, in 

 the intensive extreme a suggestion of beading of the same margin 

 is due to the breaking of the pigment into regular though subcon- 

 tiguous patches; disto-dorsal abdominal segment varying from deep 

 'chrome to sanford's brown; cerci and subgenital plate ranging from 

 deep chrome to orange rufous. Cephalic and median limbs of the 

 ■general color, more or less suffused with orange rufous distad on the 

 femora and all of the tibia, the latter in the intensive condition 

 becoming blackish brown distad. In one of the recessive specimens 

 the cephalic and median femora are dusky olive green distad. Caudal 

 femora of the g(>neral color, pattern always distinctly indicated, 

 the distal extremity always with a blackish area occupying about 

 one-seventh the femoral length, the distal half otherwise varying 

 from light orange yellow to mars yellow, passing into the color of 

 the proximal half; caudal tibia) more or less deeply and almost wholly 

 suffused with blackish brown, with a brief genicular section of the 

 general color.
