Head with I'nll (MOs, and iVont not very \\i{h'. Paljii hmir and hirire, 

 cwtendiiiii: onothird their length lieyoiid the I'nmt : third join! rather hniLi; and 

 large, oI)tuse at lip. ^fah' anteniiii' well j)ectinafed. F()r(' wiuixs: cosia 

 .straight, arehed toward the apex, whieh is snl)l'aleafe ; onter ediic ohliiiiie, 

 much less convex than in the other genera of this sidifamily. _ Hind wing.s 

 much as in Acidd/ia, being stpiare. with a well-marked angle in the median 

 edge, the apex being short and much rounded. Venation : the costal vein 

 joins the first subcostal by a very short transverse vein. 1'here is no snli- 

 cosfal arcoh:;; the first subcostal venule runs paralhd with the subcostal main 

 vein until it reaches the origin ot" the Ibnrtli venule (what is nsiutlly the iii'tli, 

 for there are but five sul)costal venules), where it diveriics to the costal edize. 

 The posterior discal venule is v-sh;iped. and ser.ds a fold inward. Hind 

 legs lon<f and slender; tibia- slender; tarsi slender, two-thirds as lonir as the 

 tibiie. Coloration: white in our American si)ecies, with deep-ochn;ous costal 

 spots and broken lines. 



This genus combines the characters of the Caherina; and Acidalinfr, 

 approaching the latter in tiie sliirhtly sublidcate fore wings and angular hind 

 wings and the general points in venation, while it dillers Irom the others ol 

 its group in the more heavily-pectinated ;mtemi;e, the larue palpi extending 

 farther l)eyond the front than usual, and the absence of one ol" the ant<nior 

 subcostal venules. 



Our S. j)ux/i//(in'a is (juite near the iMiropean .'^'. dilntaiia, which i.s 

 ochreous, lined and dusted with brown.
