19. XII. 1922. 



E. tolimus Plotz (175 b) is marked above as Gorg. patens (175 a) with but one dark median band, ioK7nw. 

 the margin being very much darkened. Beneath Hkewise similar, but the anal half of the hindwing is blue. The 

 postmedian transverse band is here very distinct. From Colombia. The species may be better inserted in 

 Gorgo'phone. 



21. Genus: Orais G. & S. 



Is very closely allied to Anastrus, chiefly distinguished by its longer and narrower cell of the forewing; 

 costal fold and hair-pencils on the posterior tibiae are absent. 



G. stigmaticus 3Iab. (= fumosus P/dfe) (175 b). A common, widely distributed, large species. Above siigmaiicus. 

 brown with 2 spotted darker transverse bands, the proximal one being shortened and provided with 2 or 3 minute, 

 white, subapical hyalme dots. Beneath somewhat lighter, otherwise marked the same. From Mexico to Panama, 

 to Colombia and Southern Brazil, occurring also in Jamaica. 



G. choricus Schs. is just as large, dark brown, with a violet lustre, at the distal margin darker, the choricus. 

 transverse bands somewhat spotted; 3 small, subapical, hyaline dots. Beneath separated by the anal part 

 of the hindwing being scaled lilac-grey, the distal brown macular band being more distinctly prominent. From 

 Mexico (Paso de San Juan). 



22. Genus: OTylon G. & 8. 



The third joint of the horizontally porrect palpi is very short. The forewings are broad, at the apex 

 somewhat stunted. The posterior tibiae exhibit a hair-pencil and 2 pair of spurs. 



M. lassia Hew. (175 c) is above whitish, dusted grey, in the basal and marginal thirds of the fore- lassia. 

 wing, and more narrowlj- at the margin of the hindwing densely dusted with brown and very much like Euda- 

 midas melander from which it is easily separated by 4-. small, hyaline, subapical spots and the long hair-pencils 

 of the posterior tibiae. Very common and widely distributed from Mexico to Colombia and Bolivia. 



M. pulcherius Fldr. (175 c) is very similar, larger, the discal area of the hindwing more uniformly p!<?c7ierii<s. 

 dusted brown, faintly contrasting with the basal and marginal areas; the dark marginal area of the hindwing 

 broader. Mexico to Colombia and Brazil. 



M. pelopidas F. Forewing above dark ash-grey with a dark brown discal line. Hindwing ash-grey, pelopidas. 

 Body dark brown, antennae black. Hindwing with darker marginal dots. Under surface ash-grey. — This 

 verj'- short description which fits to quite a number of species mentions as patria: ..in Indiis", which probably 

 means the West Indies formerly constituted by great parts of tropical America. 



23. Genus: Euclamidas G. tfc S. 



Different from Mylon mereh^ by the absence of the hair-pencil of the posterior tibiae. 



E. melander Cr. (175 c) is a well-known, very common species with greyish-white wings dusted melander. 

 brown in the basal and marginal areas, with torn, dark macular bands; easily discernible from the very similar 

 Mylon lassia by the absence of the small hyaline spots and of the hair-pencils. From Mexico to Paraguay. — 

 From Peru f. obscurlor Schs. was described; above darker and browner, foi'ewing without a discal spot, the 

 subterminal shade darker and not dentate. 



E. ozertia Btlr. (175 c) is similar, smaller, paler, more thinly scaled, somewhat iridescent, the marginal o=ema. 

 and basal areas only slightly darkened. Very common from Mexico to Colombia and Southern BrazU. 



E. cajus Plotz (175 c) is somewhat larger, with a more bent costal margin of the forewing and f.7/»s. 

 a more pointed apex. The whitish wings are dusted more reddish-brown, the discal area of the forewing is not 

 remarkably lighter, the dark antemarginal band is particularly on the forewing less dentate and more blurred. 

 Beneath almost without markings except the antemarginal bands. Hitherto apparently only known from 

 Peru and Bolivia. 



24. Genus : Xeiiophanes G. & 8. 



Separated from the preceding genera by the shorter, more rounded wings without a costal fold; nor 

 do the posterior tibiae exhibit a hair-pencil.
