PHRICODIA.—ORMISCODES. 193 
In Mexico this species is common, but I have not any evidence of its occurrence 
elsewhere in Central America ; in the State of Panama it is replaced by the very closely 
allied P. avia. I think it quite probable that P. hircia and P. avia will most likely 
prove to be merely forms of one species, the chief difference being in colour only; 
P. hircia is dark and more strongly marked with grey, P. avia of a very much paler 
and redder tint. 
3. Phricodia arcei, sp. n. 
Primaries and secondaries uniform pale brown, slightly shaded with yellow; primaries crossed by two very 
indistinct brown bands ; secondaries with a central dark band from the costal margin nearest the apex to 
the inner margin: head, thorax, and antenne pale brown; abdomen banded with black and yellow; legs 
brown. Expanse 43 inches. 
Hab. Panama, Volcan de Chiriqui (Arcé, in mus. D.). 
This species is allied to P. avia, from which it is easily distinguished by the 
different position of the dark bands on the primaries, and also by its much paler 
colour. . 
ORMISCODES. 
Ormiscodes, Blanchard, in Gay’s Historia fisica y politica de Chile, Zool. vii. p. 61 (1852). 
This genus was instituted by Blanchard for the reception of the Chilian 0. (Bombyx) 
cinnamomea, Feistl. [= 0. (Bombyx) crinita, Blanchard, op. cit., Atlas, Lep. t. 4. f. 4], 
an insect not considered generically distinct from Dirphia by Walker; it includes 
two Central-American species. 
1. Ormiscodes agis. 
Phalena Attacus agis, Cram. Pap. Exot. i. p. 49, t. 30. f. F*. 
Bombyx agis, Oliv. Enc. Méth., Ins. v. p. 38. 
Dirphia agis, Hiibner, Verz. bek. Schmett. p. 1537; Walk. Cat. vi. p. 1857. 
Hab. Mexico (Boucard, in mus. D.), Jalapa (Hoge).—Gutana, Surinam 12; Ecuapor ; 
EASTERN BraziL, Pernambuco. 
This species appears to be very rare; from our country we have only received two 
specimens, both males. A female from Ecuador, which only differs from the male in 
being very much larger, and another male from Pernambuco, are all the specimens of 
this species that I have received; the latter is considerably paler in colour than the 
Mexican examples. 
2. Ormiscodes lasiocampina. 
Ormiscodes lasiocampina, Feld. Reise d. Nov. Lep. t. 90. f. 5, Erkl. der Taf. 75 bis 107, p. 7 (2). 
Hab. Mexico (Sallé 1). | 
A very distinct species.
