portion which is Ijilobate. Cerci short, ensiform, tapering to acute apex, 

 subdeplanate dorsad, joints distinct but feeljly monihform. Internal genitalia 

 complex. Subgenital plate small, asymmetrical; with two broad, elongate 

 inset plates (the styles), the surfaces of which slope dorso-laterad, these 

 styles directed dorso-mesad with apices nearly attingent, thus forming the 

 distal surface of the subgenital plate, beneath which lies the median rotunda to- 

 trigonal produced portion of the plate; the sinistral style is decidedly the 

 smaller and leaves a distinct gap between its ventral margin and the median 

 produced portion of the plate. Limbs and armament as given in generic de- 

 scription. 



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



Very similar to male in general appearance, but with abdomen considerably 

 heavier and as a result slightly surpassing the tegminal aj)ices. Interocular 

 space nearly as wide as that between antennal sockets. Pronotum similar to 

 that of male except that the width of the cephalic portion is greater, giving 

 it a more rotundato-quadrate appearance. Supra-anal plate small, triangular, 

 but decidedly angulate-emarginate at apex with apices of lateral productions 

 rounded. Subgenital plate ample, convex, short, briefly upturned distad, with 

 a brief medio-longitudinal cleft; free margin convex proximad, then broadly 

 olituse-angulate concave beneath bases of cerci, thence evenly convex.

Head ochraceous-tawny, washed with cinnamon brown, or entirely cinnamon, 

 brown. Pronotum with disk marbled, Sudan brown to ochraceous-tawny, 

 transparent lateral portions tinged with ochraceous-tawny. Tegmina trans- 

 parent, ochraceous-tawny, the humeral trunk briefly suiTused proximad with

 tinged with brown. Abdomen, cerci and limbs ochra(^eous-tawny, tinged with 

 cinnamon brown on disto-dorsal portion in males; female darker, possibly 

 discolored. 



In addition to the type and allotype, a single paratypic male, 

 bearing the same data, is at hand. 



Neoblattella carrikeri" new species (Plate XVII, figs. 3, 4, 5 and 6.) 



The male of this insect is the most attenuate, and has the 

 proportionately longest tegmina, of any American form of the 

 Group Blattellites. The highly specialized male subgenital plate
