PHOBEROBLATTA, ne-w genus. 



Front wing' 2f times us long us ))r()ad, with strongly arched anterior 

 margin, ver}" abruptly rounded apical ))order, and nearly straight pos- 

 terior edge. Costal area narrow, attaining about three-fifths the 

 length of the wing. The subcosta advances in an almost straight 

 course^ to the anterior marg'in, and just at the base forms a many -times 

 parted branch, which occupies nearly half the costal area; further on 

 then follow 2 forked and 2 simple branches, all of which are very 

 obliquely arranged. The radial vein proceeds in a nearly straight 

 line to the end of the anterior l)order, and its first branch (radius s. 

 str.) issues very near the base, by repeated furcation separating- into 5 

 ofishoots; the 3 following forked branches are very obliquely directed 

 toward the front border. The media turns in a gentle vault toward 

 the lower end of the apical margin, to which it sends out 2 forked, 

 and one simple, very long branches. The entire inner edge is taken 

 up by the 4 obliquely placed branches of the cubitus, which are sepa- 

 rated into 14 twigs, only the basal third being filled by the small anal 

 area, which has but a limited number of. veins. The surface of the 

 wing is coarse-grained leathery, rugose, with a tendency to the 

 formation of cross veins. 



In many respects this genus recalls Fjiniorplio}>latt(i., but differs in 

 form and structure.
