212 HETEROCERA. 
ECHEDORUS. 
Echedorus, Herrich-Schaffer, Samml. aussereur. Schmett. pp. 9, 60, t. 91. ff. 521, 522; Walker, 
Cat. xxxii. p. 577. 
Herrich-Schaffer placed ‘a single species from Mexico under this generic name; 
Echedorus appears to be nearest allied to Alpis. 
1. Echedorus mexicanus. 
Echedorus meaicanus, Herr.-Schaff. Samml. aussereur. Schmett. p. 60, t. 91. ff. 521, 522°; Walk. 
Cat. xxxii. p. 577. 
Hab. Mexico!; Nicaracua, Chontales (Belt); Panama, Volcan de Chiriqui 2000 to 
3000 feet (Champion).—Ecuapor; AMAZONS. 
The specimens from Nicaragua agree well with Herrich-Schaffer’s figure and with 
the example in my own collection from the Amazons ; those from the State of Panama 
and Ecuador are much smaller and slightly darker in colour at the apex of the 
primaries. 
2. Echedorus nanus, sp.n. (Tab. XXII. fig. 16.) 
Female, Primaries light greyish fawn-colour, mottled and marked almost as in E. mewicanus, with a dark 
marking close to the apex, and a reddish-brown subquadrate patch about the middle of the inner margin 
extending across to the cell; secondaries uniform very pale fawn-colour, slightly darker along the inner 
margin; the underside as above, excepting that the dark brown mark on the primaries is hardly visible : 
head, thorax, and abdomen greyish fawn-colour, a few long black hairs along the centre of the latter ; 
antenne and palpi grey. Expanse 14 inch. 
Hab. Muxico, Jalapa (Hége). 
It is quite probable that this insect will prove to be the female of E. mewxicanus; it 
differs so much, however, in colour and in the darker markings that, without further 
evidence, I prefer to treat it as distinct, and have therefore given it a name. 
SCIATHOS. 
Sciathos, Walker, Cat. iii. p. 752. 
Walker included in this genus 8. punctigera (Stoll), from Tropical America; this is 
the only described species. 
1. Sciathos punctigera. 
Phalena Bombyx punctigera, Stoll, in Cram. Pap. Exot. v. p. 151, t. 84. f. 17. 
Sciathos punctiger, Walk. Cat. iii. p. 752°; ibid. vii. p. 1711. 
Isochroma fallax, Feld. Reise Nov. Lep. t. 83. ff. 18, 19, Erkl. der Taf, 75 bis 107, p. 7°; Stretch, 
Cist. Ent. ii. p. 14. 
Hab. Nicaraeva, Chontales (Janson); Panama, Bugaba 800 to 1500 feet (Champion), 
Volcan de Chiriqui (2idbe).—Co.omsia ?; Guiana, Surinam!; Brazin2. 
This species is found over a very extended range of country, though apparently rare. 
I have received only a few specimens.
