Coloration. — Head and pronotum chestnut brown, a narrow post-ocular bar 

 of dark chestnut brown continued feebly along the dorsal margin of the pro- 

 zonal portion of the pronotal lateral lobes. Antennae hazel, darker distad. 

 Eyes blackish brown. Dorsal field of tegmina buffy, heavily suffused with 

 chestnut brown, particularly proximad; lateral fields dark chestnut brown. 

 Underparts and abdomen cinnamon brown , the latter slightly paler. Meta- 

 pleura cinnamon brown, with an oblique bar of buffy. Cephalic and median 

 femora hessian brown, a purplish-red tinge distinct. Caudal femora with 

 pagina cinnamon brown, suffused with blackish brown at apex, ventral margin 

 strikingly straw yellow, this bar slightly broader proximad than distad, there 

 slightly invading the pagina itself. Ventral surface of caudal femora brick red, 

 becoming dragon's-blood red in sulcate portion, margined externally at margin 

 of straw yellow bar with a few black dots, which fuse into a black line proximad 

 and distad, distad occurs a broad pregenicular annulus of light buff. Caudal 

 femora with dorso-external surface immaculate cinnamon brown with a russet 

 tinge ; dorso-internal surface tawny, with three moderately well defined suf- 

 fusions of blackish chestnut brown, one of which is proximad, the most distal 

 the broadest. Internal surface of caudal femora proximad suffused with drag- 

 on's-blood red, shading into carnelian red dorsad, the second dorsal suffusion 

 broader and darker in dorsal half only, the third blackish and much broader 

 and crossing the entire internal surface, pregenicular annulus warm buff and 

 nearly as broad, genicular area externally and internally blackish except for 

 the lobes which are buffy. Caudal femora dragon's-blood red, except for a 

 very narrow blackish suffusion proximad and the spines, which are wholly 

 black. 



The series of males varies in general coloration from prout's brown dorsad 

 and tawny olive laterad, to a maximum intensive condition in which the head 

 and pronotum are blackish chestnut brown, with a comparatively broad black- 

 ish postocular bar, while the lateral fields of the tegmina are darker than the 

 pronotum. 



The females are very similar in coloration. They are a trifle less brilliant 

 and the markings are more suffused, while the dorsal field of the tegmina aver- 

 ages paler, weak ochraceous-tawny, usually with a few scattered and incon- 

 spicuous flecks of darker brown. 



In the series of adults, the pale ventro-external bar of the caudal femora is a 

 conspicuous feature, much more sharply defined than in furcatus, while in that
