Cariblatta reticulosa (Walker) (PI. XI, fig. 1; PI. XII, figs. 1 to 3.) 



1868. Blatta reticulosa Walker, Cat. Blatt. Br. Mus., p. 103. [cf, Jamaica.] 



This beautiful species is the most strikingly colored member 

 of the genus. Nearest relationship is shown to C. punctulata, 

 the present insect differing from that species mainly in the very 

 distinctive color pattern and coloration. The genitalia of the 

 two species are similar, showing only in the male subgenital 

 plate slight differences of degree. 



The following features are found in a pair from Stony Hill, 

 Jamaica. cT. Size small, form slender. Cross- veins between 

 discoidal sectors of tegmina very heavy; in the area of the dex- 

 tral tegmen which is concealed when at rest, being as pronounced 

 as the sectors themselves. Supra-anal plate very small, strongly 

 transverse, very weakly produced, with distal margin very 

 broadly convex. Subgenital plate much as in C. punctulata, but 

 with lateral portions not as much upturned and style sockets on 

 distal margin less decided, represented by very weak nicks in the 

 distal margin, these are also slightly more widely separated, the 

 space between them transverse and representing a full third 

 of the distal margin; styles as in punctulata. 



9 • Agrees with male except in the following features. Supra- 

 anal plate very small, strongly transverse, weakly produced with 

 distal margin broadly convex. Subgenital plate large, scoop- 

 shaped, as in punctulata. 



Measurements (mi jyiiUimeters) 



Though this small series shows some size variation, the colora- 

 tion is very constant. 



12 The body length of males and females of the present group is not wholly 

 comparable; the female subgenital plate in the present genus is without excep- 

 tion distinctly more produced, this dimension consequently showing a greater 

 difference in the se.xes than is true for their relative size of body.
