110 . COLOMBIAN DERMAPTERA AND ORTHOPTERA 



Type. — d^ ; Cincinnati, Sierra Nevada de Santa Marta, Mag- 

 dalena, Colombia. Elevation, 4000 to 5000 feet. July 14, 1913. 

 M. A. Carriker Jr. [Hebard Collection, Type No. 446.] 



Size no larger than the smallest species of Eurycotis, form nearly elliptical. 

 Interocular space appreciably broader than the very wide space between the 

 antennal sockets; ocellar spots distinct. Maxillary palpi short; third and fourth 

 joints subequal in length; fifth shorter, little enlarged, ventral margin oblique 

 to point of greatest width, two-thirds distance to base. Pronotum as given 

 in generic description; latero-caudal angles rather sharply rounded rectangu- 

 late. Mesonotum with caudal margin almost perfectly transverse, with 

 latero-caudal angles rather sharply rounded rectangulate. Metanotum with 

 caudal margin transverse, very broadly and weakly concave, with latero- 

 caudal angles very feebly produced, very sharply rounded, at less than a right 

 angle. Caudal margins of dorsal abdominal segments very feebly and distantly 

 beaded, latero-caudal angles very feebly acute-angulate produced, this increas- 

 ing slightly distad to seventh segment. Supra-anal plate feebly tectate with 

 sides concave, lateral margins concave convergent to distal margin, which is 

 about two-thirds as long as the plate, feebly obtuse-angulate emarginate with 

 plate there feebly subchitinous. Cerci stout, margins entire, rounding to acute 

 apex, articulations subobsolete, dorsal and ventral surfaces moderately convex, 

 the latter heavily haired. The two plates beneath the supra-anal plate, 

 which form a heavy triangular adjacent production, are large and conspicuous. 

 Beneath these are the complex concealed genitalia: genital hook elongate and 

 slender, weakly curved dextrad to suddenly incurved and broadened apex. 

 Subgenital plate of the characteristic Blattinid type; lateral margins moder- 

 ately convex to styles, distal margin between these feebly convex, transverse. 

 Styles feebly inset, small, cylindrical, similar, half as long as the distance be- 

 tween their bases. Limbs heavy, with armament heavy, as given in generic 

 description. Caudal metatarsus longer than combined length of succeeding 

 joints, decidedly thickened: all metatarsi stout, broadening in proximal third, 

 thence narrowing feebly to apex, the ventral margin broadly convex; ventral 

 surface with a row on each margin of minute spines which in the distal two- 

 thirds border the very large and elongate pulvillus. 



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



Size slightly larger than male, differing in the following features. Supra- 

 anal plate tectate, with sides declivent to near the lateral margins which arc 

 slightly raised; lateral margins almost straight, convergent to the decidedly 

 concave distal margin which equals about half the length of the plate. Subgen- 

 ital plate of the characteristic valvular Blattinid type, the valves differing from 

 those of EurycoLis mexicana in being considerably shorter than the basal por- 

 tion of the plate, with proximal suture much narrower and less strongly de- 

 fined. Caudal metatarsus decidedly longer than combined length of succeeding 

 joints, slender: all metatarsi elongate and slender, the ventral margin straight; 

 ventral surface with a row on each margin of minute s|)ines, which at the 

 immediate extremity border the large inilvillus.
