Excepting in its usually slightly shorter wings, redder tint, and the pale subapical 
border, I see nothing to separate this from the preceding species; and as our female of 
E. lugubris from Haiti is of a redder tint still, and has the wings as short as E. camer- 
tus 3, whilst a female from St. Thomas has the wings even shorter than FH. camertus ©. 
I have very little doubt that the two forms are variations of one species (see also Wal- 
lengren, CEf. Vet. Akad. 1871, p. 913); no doubt it would be easy to render it in ap- 
pearance quite distinct were we to pick out all the small and pale females of E. lugudris 
(as it seems to me that my friend Grote must have done‘); but as in our case the sexes 
arrived together from Haiti, this would be impossible. 
3. ENYO DANUM. 
Sphinx danum, Cramer, Pap. Exot. vol. iii. p. 53, pl. 225. fig. B (1782). 
Enyo danum, Hibner, Verz. bek. Schmett. p. 132. no. 142] (1816).

? Sphinx ozypete, Linneus, Mus. Lud. Ul. p. 344. no. 4 (1764). 
Tabatinga, Peru (Degand); Bolivia (Buckley); Haiti (Tweedie). BM. 
This is a well-marked species, at once recognized by the fusiform sulphur-yellow 
patch on the abdominal margin of secondaries; I believe this to be the Sph. ozypete of 
Linneus. 
4. Enyo GoRGON.

3, Brazil, 2, Rio (Stevens); ¢ 2, Venezuela (Dyson). B.M. 
Hiibner’s £. lugubris is unquestionably the typical female of that species; it has the 
same scalloped outer margin, which, however, is wanting in this species. 
1 If I have done Mr. Grote an injustice in this supposition, I know he will forgive me: but he mentions only 
‘three female specimens” in his comparative description.
