COLOMBIAN DERMAPTERA AND ORTHOPTERA 
where inesiul a very slifrht, broadly obtuse-angulate emargination is ap- 
parent. Cerei sniall, elongate and slender, the twelve joints with sutures 
well marked, the lateral margins of the joints nearly straight, but each (from 
the sixth to eleventh) distinctly narrower than its predecessor; dorsal sur- 
face flat; ventral surface of each joint strongly convex, with very narrowly 
cingvdate lateral margins. Paired plate beneath supra-anal ]date highly 
specialized; sinistral half chitinous, flattened against wa.l of anal orifice, 
with a moderately stout process below base of sinistral cercus directed cau- 
dad, this process dividing into two slender branches distad, the ventral of 
which is twice the length of the tlorsal and very slightly thickened and de- 
curved distad. Dextral half of this plate developed into a large chitinous 
ridge, from which extends ventro-sinistrad a jirocess which is heavy in prox- 
imal three-hfths, but from that point is slender, tapering gradually to its 
acute ajiex, this process showing a weak curvature dorsad, its ventral mar- 
gin armed with a few irregularly placed teeth. Subgenital ])late supplied 
with elongate scattered hairs, rather strongly convex except in distal area be- 
tween the styles, where it is flattened and slopes to the free margin. Free 
margin of subgenital plate convex to each of the styles, showing emargination 
toward the bases of each of these. Sinistral style minute, straight, simiile, 
cylindrical, feebly tapering to its sharply rounded apex, nearly four times as 
long as its basal width. Dextral style half as large, its dorsal surface armed 
with four minute teeth directed caudad, the basal one of which is dextrad 
of the line formed by the others. Exi)osed ventro-lateral i)ortions of eighth 
tergite, which are folded over the lateral portions of the subgenital ]4ate, 
large, extending nearly as far caudad as the subgenital jilate itself. 
Head blackish chestnut brown; ocellar spots, })roximal antennal joints, 
palpi and mouthparts bulTy, remaining iwrtit)ns of antennae chestnut brown. 
Limbs buffy, with spines slightly darker, except portions of the coxae, 
and cei)halic femora at base, which are suffu.sed with blackish. Abdomen 
above and below, ochraceous-tawny mesad, shading to chestnut brown 
laterad, with margins cinnamon-buff. Cerei chestnut brown. Pronotum 
dull ochraceous-orange, the caudal margin chestnut brown, the maculation 
running cephalad from the humeral angles as a weaker suffusion of cinnamon- 
brown to the cephalic i)ortion of the disk, where these darker areas broaden 
toward each other, reuniting to form a vague transverse cinnamon-brown 
band, intensifying mesad on each side, so that twin blotches of chestnut brown 
are formed. Tegmina transparent, richly tinged with antique brown, except 
toward the costal margin, which is broadly buffy, the one coloration shading 
g(>ntly into the other. Wings transparent, very weakly tinged with i)rout’s 
brown, this very heavy in entire area of costal veins.* 
Length of body, 11.8; length of pronotum, 8; width of i)ronotum, 3.9; 
length of tegmen, 11.7; width of legmen, 3.3 mm. 
Tlie tyi)o is unitjuo. 
* In this feature (uuldgoi/de agrc'es with C. Itnuprun Hebard, described from 
Panama. In ttotatnn the area of the costal veins is heavily tinged with 
prout’s brown to near the free margin, the narrow marginal portion being 
l)uffy.
