194 NORTH AMERICAN BLAITIDAE 



with glabrous surface showing minute, rather widely scattered pits; lateral portions 

 fully as chitinous as disk, moderately declivent, with margins very broadly cingulate, 

 though but little raised. Length of tegmina and wings somewhat variable, these 

 falling slightly short of, to extending well beyond, the abdominal apex. Tegmina, 

 proximad, thickly supplied with minute pits, these are in series laterad of each vein. 

 Wings transparent, except in narrow area of the irregular costal veins and distal 

 portion of anterior field, where they are translucent. Dorsal surface of abdomen 

 unspecialized. Supra-anal plate feebly and briefly convex above bases of cerci, 

 with free margin there feebh' concave; large mesal portion transverse, subtruncate, 

 weakly concave except for a weak medio-longitudinal carinula, distal margin broadly 

 convex, showing a trace of mesal emargination."^ Styles very short, joints much 

 fused, acuminate tip flattened, dorsal surface weakly convex, ventral surface more 

 strongly convex proximad. Subgenital plate very large, surface convex; distal 

 margin convex, except meso-laterad at base of styles, where it is broadly and shal- 

 lowly concave, mesad the convexity is weak. Armament of limbs, pulvilli and 

 arolia, as given in generic description. The median and caudal femora have the 

 genicular spine more elongate than the single distal spine of each ventral margin. 



Characters of Male. — (Pringabaja, Lombok, Lesser Sunda Islands.'i^) Agrees 

 with the female except in the following characters. Form slightly less robust, 

 structure not as heavy. Interocular space narrower, about three-fifths as wide as 

 that between the similar ocellar spots. Tegmina and wings decidedly more elon- 

 gate, extending distinctly further beyond the abdominal apex than in any female 

 before us. Supra-anal plate decidedly more delicate in structure, subchitinous, 

 more produced, without medio-longitudinal carinula and with distal margin more 

 'evenly convex mesad, not broadly flattened. Cerci short, stout proximad, dorsal 

 surface weakly convex, ventral surface more strongly convex proximad; first eight 

 joints brief, with lateral margins narrowly compressed, tapering rather sharply to 

 slender ninth and tenth joints, the ninth twice as long, the tenth three times as long, 

 as one of the more proximal joints. Meso-dextrad, from below, an elongate oval, 

 delicate, subchitinous plate is directed dorsad in the anal chamber, tapering evenly 

 ■distad to the acute apex."" Subgenital plate springing from bases of cerci, small 

 but broad and little produced, distal margin subsinuato-convex. Styles absent.

 the females measured above. 



SI* In some specimens, the median carinula and this trace of emargination are obsolete.
