98 HETEROCERA. 
a few indistinct spots cross the wings from the apex to near the anal angle, in others they are entirely 
wanting. Expanse, ¢ 2 inches, ¢ 22 inches. 
Hab. Costa Rica, Irazu, Rio Sucio (Rogers). 
This species seems to be most nearly allied to H. deta, but I think quite distinct. I 
have several specimens of both sexes before me, and they do not show much variation, 
excepting in the markings of the secondaries of the female. 
8. Ecpantheria ochreator. 
Ecpantheria ochreator, Feld. Reise Nov. Lep. iv. t. 101. f. 2. 
Hab. Centrat America (Salvin, mus. Felder). 
This species is only known to me from Dr. Felder’s figure. 
9, Ecpantheria atra. 
Ecpantheria atra, Oberthiir, Etudes d’Entomologie, vi. p. 109, t. 15. f. 4’. 
Hab. Mexico, Oaxaca !. 
This insect is quite unknown to me excepting by the figure. I very much doubt if 
it belongs to this genus. 
ARACHNIS.

1. Arachnis aula. 
Arachnis aulea, Hibn. loc. cit.; Walk. Cat. xxxi. p. 300*; Clemens, loc. cit. p. 526. 
Ecpantheria aulea, Oberthiir, Etudes d’Entomologie, vi. p. 111, t. 19. f. 4, 77. 
Ecpantheria incarnata, Walk. Cat. ii. p. 690°; Clemens, Proc. Acad. Phil. xii. p. 524. 
Hab. Mexico !?%, Jalapa (Hége); British Honpuras, Rio Sarstoon (Blancaneaut). 
This species varies to some extent in the markings of the secondaries; in some 
specimens they are almost black, the red bands being reduced to minute red spots. 
2. Arachnis picta. 
Arachnis picta, Packard, Proc. Ent. Soc. Phil. iv. p. 126"; Walk. Cat. xxxv. p. 1912. 
Ecpantheria picta, Oberthiir, Etudes d’Entomologie, vi. p. 112, t. 19. f. 5, 8. 
Hab. Nort America, California |—Mexico, Milpas 5900 feet (Forrer). 
The single example of what I believe to be this species is rather darker in colour 
than M. Oberthiir’s figure, but the markings agree fairly well; in all other respects it 
is the same. 
3. Arachnis sanguinea. 
Ecpantheria sanguinea, Oberthiir, Etudes d’Entomologie, vi. p. 112, t. 20. f. 1, 2’. 
Hab. MExico }, near the city (Hége). 
A single example of this fine insect was received.
