large, full and rounded, about as wide as the pronotum. Maxillary 

 palpi much as in fasciatus in general form, but with joints not as much 

 produced. Eyes not as prominent as in that species, somewhat more 

 broadly ovate. Pronotum, when compared with that of fasciatus, 

 slightly less transverse, narrowing very slightly cephalad. Tegmina 

 more than half as long as caudal femora, apex at humeral angle 

 nearly rectangulate and sharply rounded, sutural margin passes into 

 distal margin with an appreciable angulation, longitudinal veins 

 very conspicuous, cross-veinlets numerous but very faint. Wings 

 absent. Ovipositor very long, exceeding the length of the caudal 

 femur by about one-quarter, nearly straight, stout, apex of same of

the fasciatus type but slightly shorter and heavier, with dorsal margin 

 armed with prominent, sharp, regularly spaced teeth. 



Allotypic male, here selected, bears the same data as the tj^pe 

 excepting that it was taken August 16, 1902; it is also in the Univer- 

 sity of Toronto Collection. 



Description of Allotype. Size considerably smaller; form more 

 slender than the type. Tegmina are translucent and when in repose 

 the dorsal fields have the sides subparallel with the caudal margin 

 arcuato-truncate. Spines of caudal tibiae somewhat more slender 

 than in fasciatus.
