ATTACUS.—RHESCYNTIS., 191 
6. Attacus arethusa. 
Attacus arethusa, Walk. Cat. v. p. 1204'. 
Hab. Panama, David (Champion).—CotomBia!; Braziu}, 
A single specimen from the State of Panama, in very bad condition, is apparently 
referable to this species. 
SAMITA. 
Samia, Hubner, Verz. bek. Schmett. p. 156; Walk. Cat. v. p. 1222. 
Walker, using Hitibner’s generic name, included four species in this genus. Samia 
is as yet only known from North and Central America. The genus is represented in 
our country by two species. 
1. Samia calleta. 
Saturnia calleta, Westw. P. Z.S. 1853, p. 161, t. 33. f 2 (g ¢)*; Ann. & Mag. Nat. Hist. 2nd ser. 
XV. p. 297°. 
Samia calleta, Walk. Cat. v. p. 1225 °. 
Platysamia polyommata, Tepper, Bull. Brooklyn Ent. Soc. v. p. 66, t. -. f. 8%. 
Hab. Unirep States, South Arizona (Driver *).—MeExico® (Coffin 12, in mus. Oxford ; 
Glennie, Hartweg, in mus. Brit.); GuatEmata, tablelands (Salvin, in mus. Oxford). 
Closely allied to the North-American S. cecropia. Apparently a rare species. 
2. Samia montezuma. 
Saturnia montezuma, Sallé, Bull. Soc. Ent. Fr. 1856, p. xen’. 
Telea montezuma, Grote, Trans. Am. Ent. Soc. 1. p. 118’. 
Hab. Mexico’, Orizaba (Sallé +). 
This species is quite unknown to me. The following is the description :—* Port 
et taille de la Saturnia polyphemus ; ailes beaucoup plus découpées et largement dentées 
surtout aux inférieures ; les yeux 4 peu prés semblables, seulement celui des supérieures 
sensiblement plus arrondi, et celui des inférieures opaque; le bord postérieur de chaque 
aile est en outre divisé par une ligne noire sinueuse qui devient trés large sur les 
secondes ailes, ot elle forme une véritable bande noiratre irreguliére. Des environs 
d’Orizaba sur le Platanus occidentalis. Deux exemplaires.” 
RHESCYNTIS. 
Rhescyntis, Hiibner, Verz. bek. Schmett. p. 156; Walk. Cat. vi. p: 1821 (partim). 
Eight Tropical-American species were placed in this genus by Walker. As under. 
stood here, Ahescyntis will include one species (R. hippodamia) only; this is now 
known to extend northwards to the State of Panama.
