96 COLOMBIAN DERMAPTERA AND ORTHOPTERA 



genus we believe will be placed in the Opisthocosmiinae, Burr's 

 Neolobophorinae being, in our opinion, based on insufficient char- 

 acters. The head with occiput not bilobate and tegmina with 

 heavy keel in all but the distal portion, are features which readily 

 separate Neolohophora and Neocosmiella. 



Genotype. — Neocosmiella atrata new species. 



Description of Genus. — Head short, convex, with twin impres- 

 sions between eyes and with several weak concavities mesad on 

 the moderately convex occiput. Pronotum ample, subquadrate, 

 nearly as broad as head, not conspicuously narrower than width 

 across tegmina. Tegmina with a well-developed dorso-lateral 

 keel to near the distal margin. Abdomen with stink gland of 

 third dorsal segment weakly developed, that of fourth segment 

 conspicuous; sides of dorsal segments simple; ultimate segment 

 smooth, transverse, very feebly narrowing and declivent distad. 

 Male forceps elongate, without a dorsal tooth. 



Neocosmiella atrata new species (Plate XVI, fig. 4.) 



The present spfecies has no near relatives. The tegmina are 

 very similar in contour and outline to those of the Javan Sken- 

 dyle aptera (Verhoeff), as figured by Burr.^^ 



Some similarity to Neolohophora ruficeps is found in pronotal 

 amplitude, tegminal outline, all abdominal features and general 

 curvature of forceps, but that species differs very widely in 

 coloration, bilobate occiput, smooth tegmina without keels, 

 forceps without a proximo-internal tooth and with proximal weak 

 curvature extending nearly to the mesal point.

Size decidedly larger than Dinex americanus, pronotum and proximal por- 

 tion not as slender, but form very elongate. Head of same type as in Dincx 

 americanus but more elongate, with eyes less protuberant and sHghtly shorter 

 than cheeks." Antennae with first joint heavy, elongate, as long as width 

 between antennal sockets; second joint minute, scarcely longer than wide; 

 succeeding joints elongate, rod-like, increasing in length distad. Pronotum 

 subquadrate; surface irregularly moderately convex; cephalic angles rectang- 

 ulato, ratlier sharply rounded but not produced laterad in minute points as in 

 Neolohophora ruficeps and Dinex americanus; lateral margins very feebly
