122 COLOMBIAN DERMAPTERA AND ORTHOPTERA 



calated triangle very elongate and narrow. Cerci small, elongate, extending 

 caudad Ijeyond distal margin of supra-anal plate, tapering evenly to the sharply 

 rounded apex,with lateral margins distinctly crenate. Subgenital plate with 

 surface weakly convex; minute, subchitinous, slender styles situated on distal 

 margin just inside cerci, the dextral slightly the longer; distal produced portion 

 of plate between these with sinistral margin moderately convex to beyond 

 mesal point, rounding there into the straight, oblique dextral margin. 



Allotype. — 9 ; same data as type. [Hebard Collection.] 

 Body bulk larger than male; form elongate elliptical, broad. Head much 

 more simple than in male, front portion entirely deplanate, moderately punc- 

 tulate; eyes reduced, not projecting; interocular space very broad, as wide as 

 space between antennal sockets; ocelli reduced, small, smoothly concave, 

 irregularly rounded. Maxillary palpi slightly heavier than in male. Prono- 

 i,um, tegmina, wings, abdomen and limbs as given in generic description. 

 Pronotal surface more evenly convex than in male with oblique sulci of disk 

 obsolete, latero-caudal angles rectangulate, sharply rounded, caudal margin 

 perfectly transverse. Tegmina truncate, about as long as wide, roundly pro- 

 duceo'. caudad at costal margin, thence with distal margin roundly emarginate, 

 this cutting through the distal portion of the anal field, angle at sutural margin 

 slightly less than ninety degrees, with apex sharply rounded. Cerci greatly 

 reduced, very small, short; brief lateral margins entire, apex acute.

The degree and curvature of the tegminal truncation in females 

 shows some variation in the series before us. 



Coloration, (f. Type. — Pronotum with mesal portion shining black tinged 

 with chestnut and shading to chestnut meso-caudad, laterad this marking is 

 angulate produced before the mesal point, thence the lateral margins are nearly 

 straight, moderately divergent to caudal margin above humeral trinik of 

 tegmina; lateral wings transparent warm l)uff, this extending rather liroadly 

 across the pronotum along the cephalic margin, there suffu.scd caudad; punc- 

 tae in the pale area chestnut brown. Tegmina transparent, marginal field 

 warm buff, the numerous irregular veinlets more strongly so, humeral trunk 

 bay, other proximal portions washed with chestnut, this fading gradually to 

 apex of anal field and with flecks of chestnut, thence the tegmina are buffy, 

 this weakest in distal portions. Wings almost colorless, showing a faint buffy 

 tinge toward the margins of the anterior field, with an irregular line of opaque
