Eudamus orcinus, Feld. Reise d. Nov., Lep. p. 510, t. 71. ff. 4, 5 (1867) \ 



Hydraenomia orcinus, Wats. P. Z. S. 3893, p. 38 2 . 



Eudamus albicuspis, Herr.-Schaff. Prodr. iii. p. 68 (1868) (fide Staudinger) 3 . 



Alis fuscis ; anticis macula cellulari profunde fissa, altera infra earn aliis tribus discalibus tribus quoque sub- 

 apicalibus (media proxima) semihyalinis, macula ad medium marginis interni albida ; posticis fasciola 

 basali, altera discali maculosa semihyalina, lunulis submarginalibus ocbraceis quoque notatis : subtus ut 

 supra, sed pallidioribus et magis canescentibus, maculis omnibus magis obviis ; posticis ad angulum analem 

 obscurioribus, ciliis fuscis inter venas pallidioribus : palpis niveis, segmento ultimo nigro ; plica costali 

 obvia. 

 $ mari similis, sed plica nulla. 



Hab. Mexico, Atoyac (II. II. Smith), Paso de San Juan ( W. Schaus) ; Honduras 

 (Dyson) ; Panama, Chiriqui ( Trbtsch, in m,us. Staudinger), Taboga I. (J. J. Walker). — 

 South America, Guiana, Amazons Valley, Eastern x and Southern Brazil. 



This pretty species was described by Felder in 1867 from a specimen in his collec- 

 tion from Bahia, but it had long previously been obtained by Bates at Ega, in the 

 Upper Amazons Valley. We now know that it has a very wide range, extending to 

 the Brazilian provinces of Rio Grande and Matto Grosso in the south to the Mexican 

 State of Vera Cruz in the north. 



A specimen sent us by Dr. Staudinger is named " E. albicuspis, H.-S.," doubtless from 

 Herri ch-Schaffer's type. It agrees in every particular with H. orcinus, the former 

 name having been applied to it a year later. 



The male genitalia are peculiar, and unlike those of any species here placed near 

 Hydraenomia. The tegumen is short, cleft at the end, the two points divergent ; the 

 scaphium is not strongly developed ; the harpes are concave at the end, from the middle 

 of the depression is a rounded lobe covered with dentate papillae, and serrate towards 

 the base of the upper edge. (See Tab. LXXXI. fig. 18.) 



PARADROS.

Phareas, Plotz, Stett. ent. Zeit. 1883, p. 451 (partim). 



Mr. Watson's type of this genus is Eudamus phoenice, Hew., with which E. formosus, 

 Felder, is strictly congeneric. The latter species occurs within our limits, as well as 

 E. oriander, Hew. Four other species are found in various parts of South America. 



The antenna? are long, and have a long, slightly swollen club bent into an even curve 

 and ending in a fine point. Palpi with the third joint long, slender, and porrect. 

 Primaries with a slightly arched costa ; outer margin convex, cell about two-thirds the 

 length of the wing ; third median segment long, equal to the basal segment, the second 

 segment being half as long again; lower discocellular rather short, shorter than the middle 

 discocellular. Secondaries with a slight anal lobe ; the third median segment very short,
