would be considered genera, and one of these groups would 

 be divided into two or more genera. 



1. Costals with some connecting gradate or cross-veins, labial 

 palpi short; first anal in both wings runs parallel to cubital 



fork Brachynemurus 



Costals simple, or forked toward stigma 2 



2. Labial palpi greatly elongated; anal in both wings runs parallel 



to the cubital fork Scotoleon 



Labial palpi no longer than maxillary or not much so 3 



3. In hind wing the first anal runs parallel to cubital fork; more 



or less evident bent line of veins in wing Hesperoleon 



In hind wings the lirst anal bends down to margin on reach 

 ing cubital fork; the line of bent veins not plain. .Clathroneuria 



Brachynemurus Hagen. 



This genus was described with two species, B. longicaudus 

 and B. nebulosiis (=ramburi}. Both of these have some of 

 the costals connected by oblique cross-veins. In both wings 

 the first anal runs parallel to the fork of the cubitus for some 

 distance and is connected thereto by several cross-veins. The 

 palpi are short ; in the apex of wings the veins are somewhat 

 bent to form the line. In fore wing three cross-veins before 

 origin of the radial sector, in hind wings two before radial 

 sector; the spurs are not, or scarcely, equal to two tarsal joints. 

 There is no comb of bristles on the outer side of coxje I. 

 Male abdomen very long. B. tubercnlatus and B. clongatus 

 agree with the above characters ; also B. irrcgularis. 



Type. B. longicaudus Burm. 



Hesperoleon n. gen. 



Costals simple, or forked toward the stigma ; usually three 

 cross-veins before radial sector in fore wing, and two in hind 

 wing; in apex of wings the veins bent more or less to form the 

 line ; in both wings the first anal runs parallel to the cubital 

 fork for some distance, and is connected thereto by several 

 cross-veins ; spurs rarely more than equal two tarsal joints ; 

 coxa I without comb of bristles on outer side; antennae hardly 

 one-half their diameter apart ; labial palpi not elongated. 



Type. B. fcro.v Walk, (peregrinus Hagen). 



Includes many species, mostly from the West; as carnzonus,
