HISTIC#A. 
Histiwa, Walk. Cat. i. p. 216 (1854). 
This genus contains about eight or nine species, all very much alike in pattern and 
colour. Only one species, so far as I at present know, occurs in our country, the others 
being all from South America. | 
Histiea meldole. (Tab. VI. fig. 14.) 
Histica meldole, Butl. Journ. Linn. Soc., Zool. xii. p. 362*; Aid Ident. Ins. i. t. 63. 
Hab. Panama, Volcan de Chiriqui (Champion).—VENEZUELA!; TrinrpaD 1. 
Mr. Champion states that he only found this insect in the thick forest. It is 
very closely allied to H. bellatriz from Colombia, a species which seems to vary to a 
considerable extent.

Sphinx nycteus, Cr. Pap. Exot. iv. t. 825. f. F. 
Hab. Mexico, Cordova (Riimeli), Ventanas, Milpas, and Presidio (Forrer), Jalapa 
(Hoge), Valladolid in Yucatan (Gawmer); GuatemaLA, San Gerénimo (Champion) ; 
Honpuras; Nicaragua, Chontales (Belt, Janson); Costa Rica (Van Patten, mus. D.), 
Trazu (Rogers); Panama, Caldera (Champion).—VxENEZUELA??; Guiana, Surinam!; 
East Peru (mus. D.). 
This species has a very extended range, and seems to be subject to a slight amount 
of variation. The examples before me from Guatemala have all the pale markings 
much smaller than in the specimens from Mexico, but in other respects do not differ. 
Sphin nycteus, Cramer, is the female of this species. I have the male and female in 
copuld, taken by M. Boucard in Mexico.
