rounded ; lateral sections strongly deflected, the margins being straight and dis- 

 tinctly corded ; upper surface plane, moderately polished. Tegmina elougate. 

 considerably surpassing the abdomen, the greatest width proximal, suturnl mar- 

 gin straight; apex sub-acuminate; basal field narrow, slightly exceeding one- 

 fourth of the tegmina in length ; anal field acuminate pyriform in outline, anal 

 vein but slightly curved distally. Wings with the costal veins uncurved ; ulnar 

 vein bearing three complete and two incomplete rami. Supra-anal plate triangu- 

 lar, exceeding the subgenital plate in length, apex divided. Subgeuital plate 

 produced, rounded, broadly notched apically. Anterior femora armed on the 

 anterior margins with four large median spines, the apical section with a series 

 of small spines; posterior margins with two large and two medium spines on the 

 distal portion. Median femora with eight regularly distributed medium-sized 

 spines on the anterior margins, and several small and medium-sized spines 

 irregularly distributed on the posterior borders. Posterior femora armed with 

 five spines on the anterior and four spines on the posterior margins, those on the 

 latter being placed distally. 



%. — Supra-anal plate triangular in outline, the apex rounded. Subgenital

Ischnoptera sp. 



Three specimens; one male, two females; Cabanas, Pinar del 

 Rio, Cuba. (Palmer and Riley.) [U. S. N. M.] 



These specimens are so badly broken it is impossible to positively 

 determine them. They appear to approach blattoides (Saussure), 

 but differ in wing characters. No relationship exists with any of 

 the other species previously recorded from Cuba. 



Genus BLATTELLA Caudell.
