SCIABLATTA » 
This genus is nearest llhytidomelopum , differing in the larger 
size, broad form, uniform and pale coloration, moderately broad 
and unspecialized interocular space, broader tegmina, wings with 
weakly clubl)ed costal veins and different type of male genitalic 
specialization. 
The pale immaculate coloration suggests the more usual type 
in X eohlattella and, to a lesser degree, certain species of Latiblat- 
tella. 
The form is broad, more nearly as in Plalylestes and the broader 
species of Lotiblaltella, and in fact the general superficial appear- 
ance suggests a longer winged species near LatiblatteUa pavida 
(Helm). 
The genus is monotypic. Genotype. — Scietblatta mainatoco new 
species. 
Generic Description. Sexes similar, with tegmina and wings 
fully developed. Size medium large for the (Iroup Blattellae, 
form l)road for the group. Tegmina very delicate, with dis- 
coidal sectors oblique. Wings with costal veins weakly clul)l)ed, 
ulnar vein with few branches, intercalated triangle present. 
Dorsal surface of male abdomen specialized. Cerci very elong- 
ate and slender. Subgenital plate of male fused and specialized 
with the lamellate styles. Subgenital plate of female full, show- 
ing no distal cleft or emargination. \>ntro-cephalic margin of 
cephalic femora with a row of spines which decrease gradually 
in length distad, terminating in three heavy distal spines. \Tn- 
tro caudal margin of cephalic femora armed with (three or four 
and one distal) spines. Moderately well developed pulvilli 
present on four proximal tarsal joints. Tarsal claws symmetrical 
and unspecialized. Arolia present. 
Sciablatta mamatoco new species (Plate VIII, figures 6 and 7.) 
The combination of characters given in the generic diagnosis 
shows that this species is widely distinct from all previously 
known forms, showing nearest affinity to species having a very 
different general appearance.
