H. RAMuscuLA Dyar. (Plate \'I, fig. 2.) 



Zeusera ramuscula Dyar, Sci. Bull. Brook. Inst. Mus., I, 8, p. 200 (1906). 



"Closely allied to Z. ramosa. Schaus. from Brazil and the Guianas, but 

 smaller, the hind wings more bluntly rounded and more opaquely white, lacking 

 the transparency of ramosa as well as the brown strigulations, there being only 

 fuscous dots at the ends of the veins. Fore wings marked as in ratnosa but 

 the black strigae on inner half less linear, more powdery. Expanse, 30 mm. 

 Two S $, Brownsville, Texas (Doll.)."

SUBFAMILY COSSINAE 



Cossinae Neumoegen & Dyar, Jour. N, Y. Ent. Soc, II, p. 161 (1894). 



We have included the remaining genera of the Cossidae in this 

 subfamily, although Cossula is rather aberrant, diflfering from the other 

 genera in that vein Ri of primaries arises from areole and not from 

 discal cell, and that the palpi have the third joint conical and well 

 separate from the preceding. All agree, however, in lacking the anal 

 cross-vein of primaries and in having veins R and Mi of secondaries 

 stalked or from a point. 



Genus Cossula Bailey. (Type magnifica Stkr.) 



Cossula Bailey, Papilio II, p. 93 (1882); H. Edwards, Ent. News, II, p. 72 

 {1891) {Inguromorpha = syn.) ; Kirby, Cat. Lep. Het. I, p. 867 (1892) ; 

 Neumoegen & Dyar, Jour. N. Y. Ent. Soc. I, p. 33 (1893); id, II, p. 

 163 (1894); Dyar, Ent. News, IX, p. 213 (1898). 



Palpi slightly upturned, extending somewhat beyond front, last joint small, 

 conical ; antennae strongly bipectinate ; vestiture of thorax rough, scaly ; hind 

 tibiae with 2 pairs of strong apical spurs ; primaries vein R, from areole, R2 and 

 Ri stalked from apex of areole; R. and R; stalked from just below apex. Mi 

 from middle of cell, Ms-Cu™ about equidistant, from around angle of cell; ist 

 and 2nd anal veins widely separate, free; secondaries S. C. and R parallel, Mi 

 from point on R just beyond cell, other veins as on primaries ; cellula intrusa 

 on both wings; frenulum present. 



In the specimen examined the discocellular on secondaries be- 

 tween Cuj and M- is almost obsolete; we presume, however, this is 

 accidental. The venation as given above differs somewhat from Dr.
