form nnd position of the lines, however, and especially the 

 somewhat more stronjjly dentate termeii of the hind wiiifi^, 

 point to its speeifie distinetness. It is not impossible that it, 

 too, may evmtuaJly prove to be the female t) some known 

 *^ Slcna/rii/id." The f^ronp containing iliiiiidiurid, (Jncii., 

 (jiiis>ji/i/iiiri<i, (Jnen., vhniifuriti, Sncil , and others is a dillicnlt 

 one, bnt 1 have f^iven very carefnl attention to it without 

 discovering; any species to wjiieh accessilinea conld possibly 

 be referred. The females of several are already known and 

 have simple antennre. 



Note. — I have two cJ cT which probablv bcloiif^ to this 

 species; the above description wonld apply to them, with 

 the following; (lifTercnecs : — 33-3 !• ; somewhat lif^htcr, mere 

 sharply maiked ; fore wing with a curved dark shade pre- 

 cedinjj the antemedian, ni.etin;; it on inner margin ; a Hue, 

 slightly intcrrupti'd, dark nicd an line, strongly ontcnrved 

 behind cell-spot, then nearly |)arallel with |t()stmc(lian ; post- 

 nndian less sharply inbent on submcdian i'old, therefore less 

 closely ajjproaching antem ditn ; himl wing with discal spot 

 nearer to antemedian than to postmcdian, whereas in the 

 type ^ the reverse is the case ; undersidti nmch paler, that 

 of the fore wing lighter fnscons, with inner margin whitish 

 and ccll-s|)()t distinct, that of the hind wing whitish, with 

 costa slightly infuscated and cell-spot distinct ; antennal 

 jK'ctinations rather long, 



Oconequc, S.K. Pern, 7000 feet, .Inly 190 1 (G. Ockendet,) ; 

 Torne, Colombia, August 1907 ; also in coll. Dognin from 

 San Antonio. 



Perhaps nearest to the more sharply marked examples of 

 Sti'iiitUiitin cloiu/firiti (Snell.), but readily distinguished by 

 having the postmcdian line of the hind ving further from 

 the tcrmcn. 



Stenalcidia praparata, sp. n. 



fj . 32 mm. — Face fuscous above, Mhitisli below; palpus 

 fuscous ; antennal shaft bauderl whitish and fuscous ; vertex 

 and occi|)ut white ; thorax and abdomen white, marked with 

 fuscous. Hind tibia much dilated, the hair-pencil strongly 

 developed. Wings white, sparsely strigulated with brown 

 and fuscous. Fore wing with costa dark fuscous nearly to 

 antemedian line, more broadly at base; large dark fuscous 

 costal spots at the origin of the three lines, a larger blotch 

 proximally to the subtermiual, a narrow costal darkening at 

 aprx, ami strong costal strigulation in the interspaces; costal 

 spot at origin of antemedian line obli<pie outwanis, reaching 

 into cell, the line here sharply angled, becoming very oblique
