214 BRAZILIAN DERMAPTERA AND ORTHOPTERA 



humeral sinus; lateral shoulders weakly indicated caudad, broadly rounded 

 elsewhere; transverse sulcus placed slightly cephalad of the cephalic third: 

 lateral lobes of the pronotum longer than deep; cephalic margin of the lobes 

 straight obUque, ventro-cephahc angle rounded obtuse; ventral margin straight, 

 weakly obhque, ventro-caudal angle broad obtuse; caudal margin with the 

 ventral two-thirds obhque, moderately arcuate, sharply blending into the 

 rounded obtuse-angulate, but distinct, humeral sinus. Tegmina slightly more 

 than twice as long as the caudal femora, faUing slightly short of the apex of the 

 ovipositor, elongate lanceolate, the greatest width of the marginal and discoidal 

 fields contained about seven times in the greatest length : costal margin straight, 

 except for a short proximal and more gradual distal arcuation, sutural margin 

 faintly siuuate, apex rather narrowh' rounded. Wings reaching to the tegminal 

 apices. Prosternum long })ispinose: mesosternal lobes acute angulate: meta- 

 stemal lobes rectangulate, none of the angles produced. Disto-dorsal abdominal 

 segment divided mesad l)y an impressed fold (proximad) and a deep V-emargi- 

 nation (distad), the margin produced into spiniform lobes on each side of the 

 median impression; supra-coxal emarginations very deep, arcuate: cerci taper- 

 ing, acute, weakly arcuate: ovipositor moderately elongate, nearly a fourth 

 longer than the caudal femora, straight except for a faint distal decurvature, 

 faintly narrowed distad of the proximal third, this due to an offset of the cephaUc 

 margin, sul)equal in width thence, except that there is an almost imperceptible 

 widening toward the distal fourth; apex moderately acute, ventral valve falling 

 considerably short of the apex: subgenital plate with the distal margin V- 

 emarginate mesad, this flanked by acute spiniform angles; lateral margins of 

 the plate straight, converging distad to the processes margining the distal 

 emargination. Cephalic and median femora relatively short, robust, the 

 former slightly shorter than, and the latter subequal to, the length of the 

 pronotal disk; cephahc femora with two teeth distad on the ventro-cephalic 

 margin; median femora with the ventro-cephalic margin bearing three spines 

 distad. All genicular lobes more or less distinctly spined except the cephalic 

 lobe of the cephahc femora. Caudal femora slender, ventro-external margin 

 with eight to nine spines, internal margin with seven to eight spines: caudal 

 tibiae with the dorsal surface distinctly expanding distad. 



The coloration has apparently altered somewhat in drying, but we are giving 

 it as found. General color old gold, becoming dull wax yellow on the pronotum, 

 primuline yellow on the pronotal disk. Head tinted with yellow citrine, with 

 mouth-parts dull primuline yellow, a spot at each lateral base of the clypeus 

 Vandyke brown; eyes old gold, crossed by two lines of fuscous, which are con- 

 nected caudad. Pronotum with a narrow cephaUc marginal band and three 

 broader caudal areas, one on the disk and one on each lateral lobe, of hellebore 

 green. Tegmina with the anal and discoidal fields wa-shed with saccardo's 

 umber, the vicinity of the humeral trunk proximad yellow ocher, of the anal 

 vein more russet; marginal field washed with Veronese green, with a cloud of 

 bice green, costal margin of this field Veronese green to naples yellow. Cephalic 

 tibiae with the usual black areas adjacent to the foramina distinct; median 

 tibiae with a single median and paired lateral dots of fuscous. All spines
