 iiiaiiily couipouiKl veinlets, occupies the middle portion of the inner 

 niiiiiiin, whose ])iisal tiiird is taken up l)y the short, broad anal area. 

 Jn one species, distinct, closel,y crowded, and regular cross veins are 

 present; in the other, there is nothing stated on this point.

DYSMENES, new genus. 



Front wing in any case very broad, probably not much more than 

 twice as long as wide, with strongly arched anterior margin, and 

 genth^ curved posterior border. Costal area wide, scarcely reaching 

 two-thirds the length of the wing, with veins branching several times. 

 Superior principal offshoot of the radius separated into 4 twig-s, which, 

 as well as the 6 twigs of the inferior branch, all run out to the front 

 margin. The media proceeds obliquely to the apical border and sends 

 out forward 4 compound branches. Near the base the cubitus divides 

 into one superior, 3-parted branch, which extends to the apical edge, 

 and into one normal branch reaching to the end of the inner margin, 

 the twigs of which (about 5) are several times furcate and take up the 

 entire posterior border. The broad anal area occupies somewhat more 

 than one-third the inner margin. Nothing is said of cross veins.
