32 HETEROCERA. 
14. Mgeria geliformis. (Tab. V. figg. 12 & 17, ¢ 2.) 
Akgeria geliformis, Walk. Cat. vii. p.46*. 
Aigeria geliformis, H. Edwards, Papilio, i. t. 4. f. 7, 7a, p. 208?. 
Sesia geliformis, Boisd. Sp. Gén. des Lép.-Heét. i. p. 441 °. 
Hab. Nortn America, United States !23.—Mextco, Jalapa (Hége). 
The type specimen of this species is in very bad condition, being much rubbed and 
worn, and the figure given by Mr. Edwards has far too much colour on the anterior 
wings. I have both sexes before me, and have figured them from fresh Mexican 
examples. 
MELITTIA. 
Melittia, Hiibner, Verz. bek. Schmett. p. 128 (1816). 
This genus is very generally distributed, its headquarters being Asia. ‘The American 
species are rather smaller insects, and not nearly so thickly covered with scale-like 
hairs. In other respects they do not differ from their Asiatic allies. 
About eighteen species of this genus are enumerated by Walker in his Catalogue, 
three only occurring in our country. 
1. Melittia satyriniformis. 
Melittia satyriniformis, Hibner, Samml. exot. Schmett. f. 453, 454, p. 17°; Boisd. Sp. Gén. 
des Lép.-Hét. i. p. 4717. 
Melittia pulchripes, Walk. Cat. viii. p. 67°. 
Hab. Nortu America ?,—Mexico, Valladolid in Yucatan (Gawmer); GuaTEMALA, 
San Gerdnimo (Champion).— VENEZUELA ; LOWER AMAZONS®, 
2. Melittia ceto. 
Melittia ceto, Westw. Cab. Orient. Ent. 62, t. 30. f.67; Walk. Cat. viii. p. 66’. 
Hab. Norta AMERICA.—GuaTeMALA, San Geronimo (Champion); Panama, Volcan de 
Chiriqui 2000 to 3000 feet (Champion). 
This appears to be a rare insect. Mr. Champion has only sent two specimens. 
8. Melittia butleri, sp.n. (Tab. V. fig. 15.) 
Like WM. satyriniformis, but with the primaries quite hyaline, the costal margin slightly black, the hair on the 
hind legs dusky brown, without red. 
Hab. Mexico, Oaxaca (Sallé, mus. Brit.). 
A very distinct species. 
TIRISTA. 
Tirista, Walk. Cat. xxxi. p. 22 (1864). 
This genus is allied to Melittia and to Tarsa. It only contains a single species.
