 Holotype.—C?.t. No. 35383, U.S.N.M. 



ASEMOBLATTA, new genus. 



Front wing with gently' arcuate front edge, oblicjuely truncate apical 

 margin, and more strongly curved inner border; 2^ to 2| times as 

 long as broad. Costal area band-shaped, rather wide, and extending 

 al)out thrt^e-tifths the length of the wing. Superior otfshoot of the 

 radius branching out above the middle of the wing, divided into 2 to 4 

 twigs; inferior ])ranch of the radius separated into 5 to S> twigs l)y 

 repeated furcation. The media continues in a gentle oblique curve to 

 the lower extremity of the apical margin, and sends off 3 to 6 more 

 or less compound branches forward to the apical border. The like- 

 wise vaulted media reaches to the lower end of the apical edge, and 

 with its 7 to 1> in part compound branches takes up the entire pos- 

 terior margin. The anal area is proportionally «hort, and is marked otf 

 by a strongly curved fold; it occupies only one-third the length of the 

 wing and contains but a limited numl)er of veins. The intercalary 

 venation is either obliterated by the strong chitinization of the wing 

 or it consists of delicate and irregular cross veins. Prothorax nearly 

 semicircular, about one-third to one-half broader than long. 



Type of genus, Axniioldnttn (Odhi'dcophUn ((xermar).
