Trosia jeanette, new species. 



Vertex, thorax, and abdomen ocher yellow, disk of thorax dotted 

 with white, the posterior tuft orange and yellow ; front, pectus, and 

 legs gray. Wings gray, a yellow ray from base through cell, diffused 

 to costa subapically. Hind wing yellow at extreme base and along 

 inner marginal. Expanse 30 mm. 



Two males, St. Jean and St. Laurent, Maroni River, French 

 Guiana (W. Schaus). 



Type: No. 13111, U. S. National Museum. 



Allied to Trosia arpi Schaus, but the hind wings have much 

 more of gray, while the thorax posteriorly is more distinctly 

 marked with red. 



Trosia caramia, new species. 



Body orange ocher, the abdomen shading to red dorsally; thorax 

 posteriorly pink. Fore wing gray, overspread with ocherous brown, 

 shading to red at base; a yellow ray from base to beyond end of cell, 

 shading to pink beyond towards apex. Hind wing red at base and 

 along inner margin, the area beyond the cell gray. Antennae and tarsi 

 black. Expanse 35 mm. 



Four males, Rio Huacamaya, Carabaya, Peru (Schaus 

 collection). 



Type: No. 13112, U. S. National Museum. 



Genus MESOSCIA Hubner. 



Mesoscia Hubner, Verz. bek. Schmett., 194, 1816. 



Hubner cites under this genus semois Cramer (recte simois 

 Stoll, a cochlidian, genus Natada) andpusztla Cramer. Kirby 

 designates the latter as the type. I have no specimen oipusilla, 

 but Moschler gives the generic characters, and the species 

 here recorded seem congeneric. 



Mesoscia eriophora Sepp. 



Phalsena eriophora Sepp, Surin. Vlind., pi. 21, 1848. 



This species cannot be a synonym of pusilla Stoll, as that 

 has the body and hind wings red. This has these parts white, 

 shaded with dark gray. 



Anguilinia Schaus, lorna Schaus, and terminata Schaus are 

 congeneric. 



Mesoscia mirabilis Schaus. 



Trosia mirabilis Schaus, Proc. U. S. Nat. Mus., xxxix, 335, 

 1905. 



It seems necessary to remove this species to Mesoscia, 

 although with its red antennas it looks like a Hysterocladia.
