Male genitalia differing only in trifling details from those 

 of castronalis, apical part of uncus being slightly broad- 

 er and a trace of fine scobination appearing on the 

 penis. The female is unknown. 



Type locality: Avengarez, Costa Rica (July; type 

 in USNM). 



Food plant: Unknown. 



In addition to the male type there are before me two 

 males from Cayuga, Guatemala (Feb., June). They 

 are smaller than the type and somewhat rubbed and 

 faded and, as a result, considerably paler. However, 

 they agree in all other details. The species is evidently 

 very close to castronalis. 



101. Pseudocabima guianalis, new species 

 FiGUBES 220, 697 



Forewing pale brownish gray; some darker dusting 

 for a wide area along inner margin; veins very faintly 

 and irregularly outlined by dark scaling thickened at 

 lower angle of cell, the curvation of the line inward; 

 antemedial line obsolete, very faintly indicated on one 

 or two specimens; sub terminal hne obscure, more 

 sharply angulate than on preceding species. Hind 

 wing translucent white; veins partially and faintly 

 darkened ; a pale smoky brown line along termen. Alar 

 expanse, 25-33 mm. 



Male genitalia with uncus narrower in middle than 

 that of castronalis or fearnella; penis armed with a 

 cluster of very fine weak spines and scobiaations. Sig- 

 nmn of female genitalia a short cluster of blunt, thorn- 

 like disks. 



Type locality: St. Jean Maroni, French Guiana 

 (type in USNM, 61323; para types in BM and Cornell 

 Univ.). 



Food plant: Unknown. 



Described from male type and one male and two fe- 

 male paratypes from the type locality, collected by 

 W. Schaus; one female paratype from Eockstone, Es- 

 sequebo, British Guiana (Schaus); one male paratype 

 from Tumatumari, Potaro River, British Guiana, June 

 26, 1927 (Cornell Lot 760, sub. 114); one male and one 

 female paratypes from Mackenzie, Demerara River, 

 British Guiana, June 21, 22, 1927 (Cornell lot 760, sub. 

 102, 104). One of the female paratypes from St. Jean 

 Maroni bears a Hampson "cotype" label inscribed 

 "Coptarthria guianalis." Evidently another example 

 of an undescribed Hampson species. 



102. Pseudocabima euzopherella (Dyar), new combination 

 Figures 223, 693 



Myelois euzopherella Dyar, Proo. U. S. Nat. Mus., vol. 47, p. 326, 

 1914. 



Forewing gray more or less dusted with reddish brown 

 (the specimens inclined to be greasy, giving a distinctly 

 brownish shade to the wing) ; transverse lines distinct, 

 whitish; antemedial line nearly vertical, a slight bend 

 in cell, a narrow dark, outer, bordering line; subterminal 

 line with a similar dark inner border, slightly and 

 blimtly angled or rounded at vein 5; the distinctive 



mark a round blackish brown smudge, touching outer 

 margia of cell, consisting of a black discal dot surround- 

 ed by blackish or brown smudges; some broken black 

 streaks faintly indicated on the veins. Hind wing pale 

 smoky fuscous, sub translucent; veins darkened; a fine 

 dark line along termen. Alar expanse, 19-24 mm. 



Male genitalia with central area of uncus very narrow; 

 penis armed with numerous fine spines and scobinations. 

 Female genitalia exhibiting no distinctive specific char- 

 acters ; signum a row of rather stout, thornlike disks. 



Type locality: Rio Trinidad, Panamd (type in 

 USNM). 



Food plant: Unknown. 



Distribution: Panama; Cabima (May), Corozal 

 (May), Tabermlla, Rio Trinidad (June). 



Vein 3 of hind wing seems to be consistently from the 

 stalk of veins 4 and 5, though the amount of stalking 

 varies in different specimens. In the forewing, 10 is 

 from the cell, approximate to the stalk of 8-9 but not 

 from it as stated by Dyar. 



103. Pseudocabima pombra (Dyar), new combination 

 Figure 221 



Myelois pombra Dyar, Proc. U. S. Nat. Mus., vol. 47, p. 326, 

 1914. 



Forewing pale ocherous gray; transverse lines faint, 

 whitish, the antemedial near middle of wing, vertical, 

 the subterminal rather well back from termen, slightly 

 angled at middle; no discal markings; some scattered 

 dark (brownish) dusting on the veins. Hind wing con- 

 colorous with forewing, semitranslucent; the veins not 

 appreciably darkened. Alar expanse, 17 mm. 



Male genitaha similar to those of euzopherella except 

 smaller and stem of uncus more slender, differences of 

 doubtful specific value. 



Type locality: Cabima, Panama (May; type in 

 USNM). 



Food plant: Unknown. 



Known only from the male type. Evidently close 

 to and possibly only a pale suffused variety of euzophe- 

 rella. The type is somewhat rubbed. On a fresh 

 specimen in better condition the dark shading on the 

 veins of forewing presumably would be more apparent. 



104. Pseudocabima nigristrigeDa (Ragonot), new combination 

 Figures 222, 699 



Myelois nigristrigella Ragonot, Nouv. Gen., p. 7, 1888; Mono- 

 graph, pt. 1, p. 41, 1893. 



Forewing white dusted with blackish, giving it an 

 ashy gray color to the naked eye; under magnification 

 some rust colored scaling between the veins especially 

 above and along inner margin; antemedial line near 

 middle of wing, nearly vertical (very shghtly convex), 

 thin, white, bordered outwardly by a narrow, strongly 

 contrasted, blackish brown line; subterminal line curv- 

 ing outward from costa to between veins 4-5, thence 

 vertical to inner margin, white, bordered inwardly by a 

 narrow blackish brown line; a black line along dis- 

 cocellular vein and continued for a short distance along
