252 HETEROCERA. 
The two specimens obtained by Mr. Champion in Guatemala agree well with Walker’s 
type in the National collection. 
2. Comidava albulana, sp. n. 
Male. Primaries above greyish-white, sparingly irrorated with small dark scales (more distinctly so along the 
inner margin), with a narrow submarginal brown line edged with yellow on the outer side crossing from 
the apex to near the middle of the inner margin, and a small dark-coloured streak at the end of the cell ; 
secondaries pure silky-white, slightly tinted with very pale fawn-colour near the anal angle; the underside 
of both wings silky-white, the costal margin of the primaries pale yellowish-white: head, thorax, abdomen, 
and legs white ; antenne fawn-coloured. male similar to the male, but slightly larger, and the primaries 
with a second narrow zigzag line crossing from the inner margin near the base but not reaching the costal 
margin. Antenne pectinated in the male, simple in the female. Expanse 1} inch. . 
Hab. Mexico, Jalapa (Schaus). 
Two examples, one of each sex. 
GADIANA. 
Gadiana, Walker, Cat. xxxiii. p. 854. 
‘Walker founded this genus upon a single species from Colombia; this is now known 
from Chiriqui. Gadiana appears to me to be very closely allied to the genus 
Hemiceras. 
1. Gadiana rufescens. 
Gadiana rufescens, Walk. Cat. xxxiii. p. 854". 
Hab. Mexico, Paso de San Juan (Schaus); Panama, Volcan de Chiriqui (Libbe, in 
mus. Staudinger).—CoLoMBIA, Bogota !. 
A female example from Chiriqui in Dr. Staudinger’s collection agrees perfectly with 
Walker’s types; the latter are now contained in my own collection. 
ORASIA. 
Oresia, Guénée, Spécies général des Lép. vi. p. 362 (1852) ; Walker, Cat. xii. p. 942. 
Guénée and Walker include in this genus several species from India, China, Natal, 
and the Antilles. Orwsia is exceedingly closely allied to the genus Calpe, Treitsch., 
if indeed distinct therefrom. Two species occur within the limits of our fauna. 
1. Oresia excitans. 
Oresia excitans, Walk. Cat. xii. p. 942°. 
Hab. Muxico, Cordova (Hoge), Jalapa (Schaus); Guatemaua, San Isidro 1600 feet, 
Volcan de Atitlan 2500 to 3500 feet (Champion) ; Panama, near the city (J. J. Walker).— 
ANTILLES, Santo Domingo}. 
One of the specimens from the Volcan de Atitlan is considerably paler in colour than 
any of the others before me, but the markings are identical.
