370 STUDIES IN THE ISCHNOPTERITES (oRTHOPTERA) 



flagellate production, which is directed sinistrad at base but curves strongly 

 dextrad and then caudad and extends beyond apex of production of supra- 

 anal plate (sinistral style) . 



Characters of 9 • — (Azua, San Domingo.) Size and form, interocular width 

 and ocelli as in male. Supra-anal plate triangularly produced with apex 

 blunt, about as long as wide. Subgenital plate similar to that of the female of 

 capitata. Inconspicuous but distinctive features of coloration present.

 namon buff, sometimes shading on the male subgenital plate to 

 ochraceous tawny. Head with a cinnamon brown suffusion at 

 the interocellar area, rarely with merely a weak cinnamon suffusion 

 there. Lateral dots of sepia at base of each coxa and laterad on 

 the second to sixth ventral abdominal segments, these expand- 

 ing into blackish brown areas in female. Pronotum with disk 

 cinnamon brown to ochraceous buff, washed with ochraceous

XESTOBLATTA6S new genus 

 (Plate XIX, figs. 1, 2 and 5.)

 notum, even convexity of the same without discal sulci, longi- 



'''' This is noticeable, but to a lesser degree, in the other species of the Capi- 

 tata Group.
