178 GENUS CARIBLATTA (oRTHOPTERA) 



Type.— d", Caparo, Trinidad. August, 1913. (S. M. Klages.) 

 [Hebard Collection, Type No. 415.] 



Description of Type. — Size small, form rather slender, slightly more so than 

 in C. aediculata. Maxillary palpi as in C. imitans, with fifth (distal) joint about 

 three-quarters as long as fourth. Tegmina with numerous cross-veinlets 

 between discoidal sectors weakly indicated, except in portion of dextral tegmen 

 concealed when at rest. Supra-anal plate very small, transverse, distinctly 

 but not strongly triangularly produced with apex rounded. Subgenital plate 

 with dextral surface convex and curving inward above sinistral portion; 

 sinistral portion strongly and narrowly produced sinistrad, with lateral 

 margins parallel and ventral surface transversely convex, this produc- 

 tion truncate distad with angles rounded; adjacent to this production dextrad 

 is another lesser production, with lateral margins convergent and ventral 

 surface transversely convex, this briefly truncate disto-sinistrad and briefly 

 and roundly produced disto-dextrad. The greater portion of the plate is 

 occupied by these two channeled processes. Within the apex of the sinistral 

 production hes normally concealed a rather thin circular disk, with free margin 

 thickly clothed with microscopic chitinous spines arranged in a whorl; within 

 the niche formed by the distal truncate portion of the dextral process lies 

 normally concealed a rather thin but moderately broad projection, longer than 

 broad, with apex clothed with minute chitinous spines. 



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

 Description of Allotype. — Agrees with the male sex except in the following 

 features. Form very shghtly more robust. Tegmina very slightly shorter. 

 Supra-anal plate very small, strongly transverse, weakly produced, with distal 

 margin nearly transverse in greater part, this margin weakly convex laterad and 

 very weakly emarginate mesad. Subgenital plate large but not as large as in 

 themajority of the species of the genus, scoop-shaped, distal margin proximo- 

 laterad decidedly convex, then as decidedly concave at base of cercus, thence 

 moderately convex to the moderately produced apex which is somewhat 

 obtuse-angulate emarginate, the apex being distinctly less produced than in 

 aediculata.

 between eyes a broad weakly defined band of bister, ventrad of 

 this a narrower, concave, weakly defined band of the same color 

 between the occllar spots and on the face two very narrow, mesally
