190 HETEROCERA. 
(Boucard, in mus. D.); GuatEMaua, Polochic valley (Salvin, mus. Oxford); Costa Rica 
(Van Patten); Panama, Volcan de Chiriqui 2000 to 3000 feet (Champion; Arcé, in 
mus. D.). 
This species is not uncommon in Mexico, but becomes rarer southwards. From the 
State of Panama I have only seen two specimens, one sent some years ago by Arcé and 
the other quite recently by Mr. Champion; I have no evidence of its occurrence 
further south. A. orizaba varies considerably in colour ; the examples from the Volcan 
de Chiriqui are very much darker and larger in size than those from more northern 
localities. 
3. Attacus lebeaui. 
Aittacus lebeaui, Guérin-Méneville, Rev. et Mag. Zool. 1868, p- 820°. 
Attacus bolivar, Maassen & Weymer, Beitr. zur Schmett. f. 27. 
Hab. Muxico, Jalapa (Hoge), Cordova (Riimeli); Panama, Volcan de Chiriqui 4000 
feet (Champion ; Ribbe, in mus, Staudinger).— VENEZUELA, Caracas !. 
We have received a number of specimens of this species from Mexico, where the 
insect appears to be common. An allied insect, A. cinctus, Tepper (Bull. Brooklyn 
Ent. Soc. v. p. 65, figg. 1, 2), is found near our northern boundary, in Southern 
Arizona ; this species, judging from the figure, is close to A. lebeaui, but differs in 
having the transparent spots nearer the base of the wings. 
Very rarely on tree-trunks in the humid forest-region west of the Volcan de 
Chiriqui (Champion). 
4, Attacus jorulla.

Attacus jorulla, Walk. Cat. v. p. 1202°; ibid. xxxii. p. 5244. 
Hab. Mexico ®, Valladolid in Yucatan (Gawmer), Cuantla (Coffin !2), Orizaba4 (Sallé, 
in mus. Brit.). 
We have only received a single specimen of this insect from Yucatan. It agrees 
well with Westwood’s figure. 
5. Attacus speculifera. 
Attacus speculifera, Walk. Cat. v. p. 1206 (¢)*. 
Hab. Mexico * (Glennie); ?Guaremata (Sallé); Nicaracua, Chontales (Belt); Panama, 
Volcan de Chiriqui (mus. Staudinger).—East Perv; Brazit!. 
This species is found over a very wide range of country. The specimens from 
Central America are smaller and brighter in colour than those from Brazil. The 
Guatemalan insect referred by Walker (Cat. v. p. 1204) to Attacus aurota, Fabr., is, 
I have little doubt, identical with this species ; so far as I have been able to ascertain, 
this specimen is not now in the British Museum.
