purest on the disk of the pronotum, on the dorsum of the abdomen 

 being solid, bounded by the pale marginal lines on the segments, 

 frequently l)isected by an adventitious pale medio-longitudinal line 

 or divided by a broad median area of the lateral color and in the 

 extreme condition only present laterad in the neighborhood of the 

 pale lines. Head of the male with the cephalic and lateral aspects 

 slightly paler than the lateral color, varying from baryta yellow to 

 chalcedony yellow, an infra-ocular bar of Indian red frequently 

 present, rarely observed, and then but faintly, in the paler specimens; 

 eyes varying from light buff to seal brown, this apparently due in 

 part to the drAdng of the insect ; antennae varying from raw sienna to 

 kaiser bro^vn, the proximal joint in greater part of the color of the 

 face. Pronotum of male with the pale lateral lines varying from 

 nearly pure white to bufT yellow in one extreme and viridine yellow 

 in the other, always broader cephalad and caudad than mesad, 

 generally severed once and sometimes twice at the point of greatest 

 constriction; lateral lobes of pronotum with a trace of the dorsal 

 color present cephalad and caudad contiguous to the pale bars. 

 Tegmina of the male with the underlying color varying from bay to 

 maroon, the venation and marginal field similar to the pale lateral 

 bars of the pronotum in color; base of the narrow discoidal field 

 entirely sufTused with weak mahogany red or bright chestnut, the 

 pale veins of the distal portion of the same field sharply contrasted. 

 Disto-dorsal abdominal segment of the male washed with yellow, 

 varying from pale cadmium to mars yellow, the cerci wholly of the 

 same color. Cephalic and median femora of the male with more or 

 less of their length ochraceous-orange, occasionally green without 

 any of the former color; cephalic and median tibiae with green the 

 underlying color, more or less suffused with ochraceous-orange or 

 occasionally (Victoria, Tamaulipas, specimens only) almost wholly 

 blackish, the region of the tympanum almost invariably (but a single 

 exception) touched dorsad with blackish. Caudal femora of male 

 with the proximal three-fifths parrot green'* with a medio-lateral 

 stippled pattern of blackish; distal extremity of femora blackish 

 brown of variable intensity, rarely very weak, remainder of distal 

 two-fifths of the femora varying, with the general tone, from mustard 

 yellow to zinc orange. Caudal tibiae of male with their ventral color 

 agreeing with the yellowish distal portion of the femora, but dorsad 



1* Even in the specimens with honey-yellow lateral aspects (Victoria, Tamauli- 

 pas) the femora are parrot green, which would lead one to the conclusion that 

 green was the natural coloration of the greater portion of the whole insect.
