74 HETEROCERA. 
HELIURA. 
Heliura, Butler, Journ. Linn. Soc., Zool. xii. p. 417, t. 29. figs. 18, 17. 
This genus was founded by Mr. Butler for the reception of eight species, some of 
which are extremely close to Charidea; but he has since taken out H. apicalis and 
proposed a new genus for it. 
1. Heliura leneus. 
Sphinx leneus, Cram. Pap. Exot. iii. t. 248. f. G. 
Heliura leneus, Butl. Journ. Linn. Soc., Zool. xii. p. 418. 
Hab. British Honpuras, Belize (Blancaneaux); Panama, Volcan de Chiriqui 
(Champion). 
This appears to be a very scarce insect; I have only received two examples. The 
specimen from Belize is much smaller than the one from Panama: it is in poor con- 
d tion, and without more material I prefer keeping it with H. leneus for the present, 
though it is quite possible it may prove to be distinct. 
2. Heliura lamia. 
Heliura lamia, Buti. Ill. Typ. Lep. Het. 1. t. 16. f. 8; Trans. Ent. Soc. 1878, p. 44. 
Hab. Guatemata, Duefias, Volcan de Atitlan (Champion) ; Costa Rica (Gabd, mus. D.). 
—wN. Brazit. 
The specimens from Guatemala agree in all respects with those from Costa Rica. 
3. Heliura testacea, sp. n. 
Primaries pale brown, slightly hyaline near the base, a slightly hyaline narrow band crossing the wing beyond 
the middle from the costal margin to near the anal angle; secondaries whitish hyaline, the apices and outer 
margins broadly bordered with black; thorax and abdomen pale brown: head, underside of thorax, and 
abdomen chrome-yellow ; antenne and palpi black; legs pale brown. 
Hab. Guatemaa, Pantaleon (Champion); Panama, Volcan de Chiriqui (Trétsch, mus. 
Staudinger). 
This species is most nearly allied to H. lamia, though very distinct from that insect. 
4. Heliura atava, sp. n. | | 
Primaries brownish black ; secondaries whitish hyaline, with the apices and outer margins broadly banded with 
black; thorax and the upper and under side of the abdomen brown, the sides bright metallic blue: the 
front of head, palpi, and antenn brownish black ; the back of the head and underside of the thorax pale 
carmine ; legs brown. Expanse 1? inch. 
Hab. Panama, Colon (Boucard, mus. D.). 
This species differs from all others that I am acquainted with. 
5. Heliura solicauda. 
Heliura solicauda, But). Journ. Linn. Soc., Zool. xu. p. 418°.
