bifurcated. Considering that e. g. a forked median vein is one of the 

 characters of Elllpsidion, Saussure (= Apolyta Brunner) to distinguish it 

 from alHed genera with simple veins, it shows with what caution such-hke 

 differences must be employed for generie distinction. Finally the ulnar vein 

 of the left wing gives off 5 branches, of which the 4th is bifurcated, the 

 others simple; the right ulnar has 4 branches, of which the third is bi- 

 furcated, the others simple. 



The armature of the front femora conforms with Shelford's type "B", 

 in his "Preliminary Diagnose of some new genera of Blattidae" ') where 

 he proposes to split up Phyllodromia, Serville into six genera. This, 

 together with the ramose character of the ulnar vein of the wings and the 

 only slight development of the apical triangle, would bring this species under 

 the genus Eoblatta, Shelford, of which Blatta nottilata, Stal, is the type.
