BRADYBLATTA, new genus. 



Related to Plnjlohlatta and L!p((rol>liitta., but differs in the much 

 more blunth' cordate form of the w ing-, the U^ngth of which amounts 

 to not quite twice the breadth. The relativel}' narrow, Ijand-shaped 

 costal area extends three-fifths the length of the wing. With its last 

 branches, the radius continues down to the apical margin; it sends out 

 5 branches anteriorly, the first two of which alwa3^s separate into 3 

 twigs. The media gives off' 5 simple, parallel branches forward to the 

 apical border. The cubitus is normall}^ formed, with 7 offshoots 

 branching backward. Anal area very large and not longer than high, 

 with about 5 to 6 veins. Cross veins are not to be seen.

EXOCHOBLATTA, new genus. 



In form similar to Bradyl>l<ttta. Front wing cordate, twice as long- 

 as broad. Costal area ))and-shaped, but only half as long as the wing. 

 Radius . forming successively one simple branch, then one l:-parted,^ 

 then one forked, and ffnally one more simple one, which take up the 

 entire anterior margin. The media appears quite uniquely con- 

 structed ; it advances in a short curve to the middle of the posterior 

 margin and sends out toward the apical border 3 l)ranches that are 

 nearly parallel with each other as well as with the inner margin. The 

 strongly reduced cubitus forms but 2 furcate offshoots, and the large 

 anal area contains several compound veins. No cross veins.
