men. Tegmina with longitudinal discoidal sectors. Wings with the anterior 

 part rather narrow, scarcely tapering to the base, ulnar veinjsimple or bifurcate, 

 very rarely tri-ramose, no apical triangle. Front femora armed on the anterior 

 margin beneath with a complete row of spines, the more distal shorter than the 

 more proximal (Type A). Sexes similar. Ootheca coriaceous, carried by the 

 female with the suture directed to one side. 



Type of the genus : Blatta germanica, L. 



NeoblatteUa, gen. n. 



Resembles Blattella, but differs in the following points : the anterior part 

 of the wing is broader, especially at the apex, and tapers towards the base ; 

 the ulnar vein of the wings is ramose. The apical triangle is inconspicuous or 

 absent. 



Type of the genus : Blatta adspersicollis, Stal. 



Margattea, gen. n. 



Differs from NeoblatteUa in the armature of the front femora ; these are 

 armed on the anterior margin beneath with 3 to 5 strong spines succeeded dis- 

 tally by a close-set row of minute piliform spines (Type B). 



Type of the genus : Blatta ceylonica, Sauss. 



Supella, gen. n. 



Sexes dissimilar. Male rather narrow and elongate, with the tegmina and 

 wings extending considerably beyond the apex of the abdomen. Tegmina with 

 the discoidal sectors oblique. Wings with the ulnar vein ramose, no apical 

 triangle. Front femora armed after Type A. Female shorter, broader, more 

 convex, resembling certain species of Ceratinoptera ; tegmina and wings not 

 exceeding the apex of the abdomen ; idnar vein of wing ramose. Ootheca 

 chitinous, carried with the suture directed upwards. 



Type of the genus : Blatta supellectilvum, Serv. 



Eoblaita, gen. n. 



Sexes similar. Form not conspicuously narrow and elongate. Tegmina 

 and wings not exceeding the apex of the abdomen by much. Tegmina with 

 the discoidal sectors oblique. Wings with the anterior part broad, tapering to 

 the base, ulnar vein ramose, apical triangle inconspicuous or absent. Front 

 femora armed after Type B. 



Type of the genus : Blatta notulata, Stal. 



Chorisoblatta, gen. n. 



Tegmina with the discoidal sectors oblique. Wings with the anterior part 

 broad and tapering to the base, ulnar vein ramose, a large, well-marked apical 

 triangle. Femora armed after Type A or Type B, remaining femora strongly 

 armed. 



Type of the genus : Blatta lit ur if era, Stal.
