ESTHEMA.—EUCYANE. 103 
1. Esthema, bicolora. 
Phalena bicolora, Sulz. Ins. p. 161, t. 22. f£.6; Cram. Pap. Exot. ii. t. 143. f. A. 
Esthema bicolora, Walk. Cat. ii. p. 888’; Butl. Trans. Ent. Soc. 1872, p.52; Ann. & Mag. Nat. 
Hist. 4th ser. xvi. p. 172. 
Hypocrita dichroa, Hiibn. Samm. exot. Schmett. i. t. 187. 
Hab. Costa Rica (Van Patten, mus. D.).—Amazons!; East Perv (mus. D.). 
This species appears to be very rare in Central America. I have only seen the single 
specimen sent some years ago in Dr. Van Patten’s first Costa-Rican collection. 
2. Esthema aletta. 
Phalena aletta, Cram. Pap. Exot. iv. t. 396. f. C. 
Esthema aletta, Walk. Cat. ii. p. 388; Butl. Trans. Ent. Soc. 1872, p. 52; Ann. & Mag. Nat. Hist. 
4th ser. xvi. p. 178. 
Hab. Guatemata (Boucard, mus. D.); Panama, Veraguas (Arcé, mus. D.), Volcan de 
Chiriqui (Ribble and Arcé, mus. D.), Bugaba 800 to 1500 feet (Champion).—CoLoMBIA 
(mus. D.); Gutana, Surinam!; Ecuapor (mus. D.). 
This species is very common at Bugaba. Mr. Champion obtained a very fine series. 
3. Esthema eupleoides. (Tab. X. fig. 12.) 
Esthema eupleodes, Butl. Ann. & Mag. Nat. Hist. 4th ser. viti. p. 285°; Trans. Ent. Soc. 1872, 
p- 52; Ann. & Mag. Nat. Hist. 4th ser. xvi. p. 178. 
Hab. Costa Rica (Van Patten, mus. D.); Panama (Salvin, mus. Oxford).—CoLomB1a |, 
This species is allied to £. aletta, from which it is readily distinguished by the 
— different position of the band of white spots on the primaries, and by the white streaks 
of the secondaries extending to the outer margin. It seems to be a scarce insect. 
Mr. Champion did not meet with it. I have seen five examples, all constant in their 
differences from L. aletta. 
EUCYANE. 
Eucyane, Hiibner, Verz. bek. Schmett. p. 177. 
This genus is exceedingly well represented in Central America; the species are all 
large and very finely coloured, but none of them are common insects.

Callimorpha? pylotes, Westw. ed. Drury, ii. t. 5. f. 3. 
Eucyane pylotes, Walk. Cat. ii. p. 362°; Butl. Trans. Ent. Soc. 1872, p. 53°; Ann. & Mag. Nat.

Only a single example was obtained. I have compared the type of Boisduval’s
