Color Notes. — In recessive individuals this species is unicolorous, 

 while in intensive individuals the dorsal color is distinctly darker 

 than the lateral, and pale paired bars are more or less decidedly indi- 

 cated in all but the extreme recessive specimens. The extreme 

 recessive condition is represented by one female, closely approached 

 by another of the same sex and less closely by a male. The extreme 

 intensive condition is represented by one male and one female and 

 approached by three other females. The type is nearly intermediate 

 between the extremes, but slightly nearer the intensive condition; 

 the allotype approaches the intensive condition, but is not typical 

 of it. The extreme recessive condition ( 9 ) is uniform light brownish 

 olive except for the tegmina. The extreme intensive condition in 

 the male has the dorsal color maroon along the lateral margins of the 

 area on the head, disk of pronotum, and abdomen, paling to cedar 

 green and weak buff yellow (on abdomen only) mesad, while in the 

 female the general tone of the dorsum is tawny, washed with claret 

 brown caudad on each abdominal segment and margined laterad 

 by the same. The suffusing color of the dorsum is largely produced 

 by stippling and the extreme margins of the pronotum and abdominal 

 segments are of the color of the pale lateral lines beaded with the 

 suffusing tone. The dorsal color of the male ranges through old 

 gold with weakly indicated blackish lateral margins, of the female 

 through kildare green finely sprinkled with maroon. Pale lateral 

 lines varying from chalk white to weak orange pink (in part only and 

 in the intensive male), narrow in the female and l)road in the male, 

 cover the entire marginal field of the tegmina in both sexes. 

 In the male these lines are crenulate on the al)domen, while in the 

 female they are more or less obliquely offset on each segment. Lateral 

 color of male varying from yellowish olive green (intensive extreme) 

 to chamois (recessive extreme), in the female from the recessive 

 extreme with it uniform with the dorsum to the intensive extreme
