HETEROCERA. 
This species seems to have an uninterrupted range over a very wide area. I am 
unable to detect any tangible specific characters whereby to separate the large series of 
specimens before me. It remains a question whether the insect described by Cramer as 
Sphine fadus is really distinct from A. tantalus. The figure, it is true, shows no abdo- 
minal white band on the upper surface; but this, I think with Boisduval, is probably 
due to the greasy state of Cramer’s specimen. I have a Mexican example in this con- 
dition, which is not separable from others in the normal state. Mr. Butler keeps the 
two insects separate, but gives no reasons for so doing. Boisduval, in his latest work 
on the Sphingide (Sp. Gén. des Lép. Hét. i. p. 358, 1874), was strongly of the opinion 
that Macroglossa tantalus, M. titan, and M. fadus were only varieties of a single 
species. 
EUPYRRHOGLOSSUM. 
Eupyrrhoglossum, Grote, Pr. Ent. Soc. Phil. v. p. 42 (1865). 
A purely Neotropical genus containing two species, both of which are found within 
our fauna. 
1. Eupyrrhoglossum sagra. 
Macroglossum sagra, Poey, Cent. Lep. dec. 2* (fide Butler). 
Macroglossa sagra, Walk. Cat. viii. p. 89°; Boisd. Sp. Gén. des Lép. Hét. i. p. 360°. 
Eupyrrhoglossum sagra, Butl. Trans. Z. 8. ix. p. 531°. 
Hab. Panama, Chiriqui (Areé, mus. D.).—Cusat?; CoromBia?; Ecuapor (mus. D.); 
Uprer Amazons (mus. D.); Brazin? 3, 
A wide-ranging southern species, of which I have as yet seen only a single Central- 
American specimen, which was taken near Chiriqui. 
2. Kupyrrhoglossum ceculus. 
Sphinz ceculus, Cr. Pap. Ex. ii. p. 80, t. 146. f. Gt. 
Macroglossa ceculus, Walk. Cat. viii. p. 88°; Boisd. Sp. Gén. des Lép. Hét. i. p. 359°. 
‘Macroglossum fasciatum, Sw. Zool. Ill. iii. t. 1382. f. 2%. 
Macroglossa corvus, Boisd. Lép. Guat. p. 66°? 
Hab. Mexico?; Guaremaa, El Jicaro and Cubilguitz (Champion); Nicaracua®; 
Panama, Chiriqui (Arcé, mus. D.).—CotomBia*; Ecuapor (mus. D.); Trinmap (mus. D.) ; 
Guiana, Surinam !, Cayenne*?; Amazons, Para?; Brazin 234, 
A. species closely allied to the last, but easily recognized by the greater width of the 
yellow fascia on the secondaries and the absence of the yellow margin. WV. corvus is a 
“name proposed by Boisduval for a specimen said to have come from Nicaragua®. I 
believe it belongs to this species, but am not certain on the point.
