40 NORTH AMERICAN BLATTIDAE 



hook, curving strongly dorsad then dextrad but with distal portion straight, hollow, 

 with external face convex but with a faint medio-longitudinal sulcus which ter- 

 minates just before the rounded apex. Subgenital plate not large, somewhat asym- 

 metrical; with two elongate, heavy, inset plates (the styles) lying dorsad along the 

 nearly straight lateral portions of the distal margin (of w-hich the dextral i)ortion is 

 the more strongly produced), produced and adjacent mesad in slender, flattened 

 projections; the disto-mesal portion of the plate slanting upward, triangularly 

 produced, completely filling the space between the proximal portions of these pro- 

 jections; w^hile within, from base of sinistral projection, a somewhat more strongly 

 chitinous, flattened, cylindrical process is directed dorso-caudad, its apex slightly 

 broadening and faintly roughened, with distal margin rounded, situated between 

 the distal portions of the styles," not enlarged and flattened caudad and in an 

 abruptly different plane to the dorsal surface of the shaft as inL. lucifrons. Limbs 

 and armament of same as given in generic description. 



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



Description of Allotype. — Agrees with type except in the following features. 

 Form slightly broader. Head with interocular space wader, about two-thirds as 

 wide as space between antennal sockets. Tegmina slightly, but appreciably, less 

 elongate, with structure as in male. Dorsal surface of abdomen unspecialized. 

 Supra-anal plate triangular in general outline, with a medio-longitudinal sulcus; 

 lateral margins weakly concave, meso-distad the plate is weakly emarginate. Sub- 

 genital plate large, scoop-shaped, extending a little beyond apex of supra-anal plate, 

 lateral portions produced and raised, with margin convex to point where cerci pro- 

 ject, there rather decidedly obtuse-angulate, rounded emarginate, with remaining 

 portion of free margin convex to a rather deep, longitudinal, linear cleft meso-distad.

 either the supra-anal or subgenital plate.
