8 HETEROCERA. 
GONENYO. 
Gonenyo, Butler, Trans. Z. 8. ix. p. 543 (1877). 
Mr. Butler states that this genus differs from Hnyo in the form of the palpi, and 
also from Callenyo in the more highly developed palpi, the length of the abdomen, the 
undulation of the outer margin of primaries, &c. I must say that I find the differences 
between many of these genera of Sphingide so slight that I much doubt their value ; 
and had I time to work out all the characters of the different genera, I feel sure 
some of them would have to be given up for want of definite characters.

HEMEROPLANES. 
Hemeroplanes, Hiibner, Verz. bek. Schmett. p. 1383 (1816). 
This genus is allied to Enyo, from which it differs as follows :—The wings are much 
broader, the body much larger and more robust, and the antenne longer and more 
slender. It is a Neotropical genus, two of the four known species being found in 
Central America. 
1. Hemeroplanes triptolemus. 
Sphinx tripolemus, Cr. Pap. Ex. t. 216. f. F’. 
Calliomma triptolemus, Walk. Cat. viii. p. 111%. 
Madoryz triptolemus, Boisd. Sp. Gén. des Lép. Hét. i. p. 154°. 
Hab. GuateMaua, Coban (Champion); Panama, Colon (Boucard, mus. D.).—Ecuapor 
(mus. D.); Guiana, Surinam !, Cayenne®; Amazons, Para ?, Ega?; Braziu?. 
This species seems to have a very extended range, though I have only seen two 
specimens from Central America; they do not appear to differ in any respect from the 
South-American form. 
2. Hemeroplanes oiclus. 
Sphine oiclus, Cr. Pap. Ex. t. 216. f. C’; Merian, Ins. Surinam, t. 39°. 
Madoryx oiclus, Boisd. Sp. Gén. des Lép. Hét. p. 151°. 
Hab. British Honpuras, Belize (Blancaneaux) ; GuatemaLa (Boucard, mus. D.).— 
GUIANA, Surinam ! ?, Cayenne °. 
I have only seen two specimens, both of which are in bad condition; but I have no 
doubt they are of this species.
