SISYROSEA (?) PARVA, new species. 



Closely allied to phara Driiee, but smaller, paler, and more yellow- 

 ish, the head more prominent. Fore wings 3'ellowish ocherous, irrorate 

 with brown, with a narrow outer line parallel to the margin and traces 

 of a discal mark. Hind wings more brownish. 



Expanse. — 18 mm. 



Locality. — One female, Aroa, Venezuela (W. Schaus). 



Type.— Cut. No. 8984, U.S.N.M. 



SISYROSEA (?) FLEXILINEA, new species. 



Allied to fliara Druce, but larger, darker, the outer line flexuous. 

 Dark reddish brown; an outer line, slender, finely waved, bent inward 

 below vein 2, else arcuate and parallel to the margin. A dark apical 

 shade resting on the line; a dark cloud about origin of veins 2 and 3. 

 Thorax dark purplish; hind wings darker than fore wings. 



Expanse. — 25 to 27 mm. 



Locality. — Two females, St. Jean, Maroni River, French Guiana 

 (W. Schaus). 



Type.—Q2it. No. 8985, U.S.N.M. 



These three species, phara., parva.^ and flexilimea' are not properly 

 referred to S/syrosea., as the costa is not straight as in that genus; but 

 they can not be correctly referred without males. The hind tibiae 

 have no middle spurs. 



SISYROSEA (?) ASSIMILIS, new species. 



Agreeing with the preceding structurally', except that the palpi are 

 very short and frail, scarcely reaching the front. It probably deserves 

 a new generic name, but must await the discovery of the male. 



(Coloration of 8. phara Druce, but the fore wings lighter, the line 

 narrower and the outer margin tinted darker in purplish. Hind wings 

 blackish brown with pale fringes. 



Expanse. — 21 mm. 



Locality. — One female, Jalapa, Mexico (W. Schaus). 



Type.— Cat. No. 8986, U.S.N.M. 



Genus EUPROSTERNA, new genus. 



With the characters of Natada, but the palpi long and upturned 

 about to vertex of head. The male antennas are bipectinated to the 

 tip, slender, moderate, with short pectinations. 



Type. — Euprosterna a?Yjensis Schaus. 



EUPROSTERNA URBA Druce. 

 Euclea urba Drvce, Biol. Cent. -Am., Lep. Het, I, 1887, p. 216. 

 Locality. — Costa Rica.
