180 GENUS CARIBLATTA (oRTHOPTERA) 



median emargination. Subgenital plate with free margin proximo-laterad 

 very briefly straight and liorizontal, then abruptly and sharply declivent, thus 

 rectangulate at the base of the cercus; bearing ventrad of the base of the cercus 

 a small, smooth, stout finger with its external surface concave and rounded 

 apex suppUed with several minute chitinous spines, and immediately ventrad 

 of this a minute, conical style with apex very sharply rounded; the entire 

 distal portion of this margin is produced beyond this point with acute angu- 

 late, shghtly divergent projections which extend slightly beyond the apices 

 of the styles; the median portion of the margin is transverse. 



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

 Description of Allotype. — Agrees with type except in the following features. 

 Form somewhat more robust. Tegmina proportionately shorter than in male, 

 not as much so as in imitans. Supra-anal plate very small, strongly trans- 

 verse, weakly produced, with distal margin weakly triangularly produced with 

 apex rather narrowly but decidedly rotundato-emarginate. Subgenital plate 

 large, scoop-shaped; free margin proximo-laterad decidedly convex, then 

 distinctly but not as strongly concave at base of cercus, thence convex to an 

 equal degree to the decidedly produced apex.

Coloration. — Almost identical with that of C.fossicauda, except- 

 ing that in both sexes the markings of the ventral surface of the 

 abdomen are as heavy normally, as in the maximum condition of 

 intensive coloration in that species, sometimes being distinctly 

 more extensive, that of the female occasionally reaching to the 

 base of the subgenital plate. 



Specimens Examined: 11; 5 males and 6 females.

Cariblatta imitans new species (PI. XI, fig. 20; PI. XII, fig. 21.) 



In general appearance this species closely resembles C. fossi- 

 cauda and C. aediculata but with the inconspicuous color pattern 

 of head and pronotum somewhat ol)scured. The species is 

 distinctive in the genus in having the male subgenital plate 

 simply formed and bearing two unspecialized styles.
