The members of this genus can generally be distinguished from the other Geometrinze 
by the outer margins of both wings being white or pale fawn-colour, or in some cases 
blotched with white or reddish-brown. It contains a large number of species, and is 
very widely distributed. 
1. Comibzena venezuelata. (Tab. XLIX. figg. 14, 15, 3.) 
Comibena venuzuelata, Walk. Cat. xxii. p. 570 (¢)’. 
Hab. Mexico, Jalapa (coll. Schaus); Nicaragua, Chontales (Belt); -Payama, near the 
city (J. J. Walker).— VENEZUELA}. 
The three specimens before me show considerable variation in the colour of the 
underside—deep yellow in. the one from Mexico, pale yellow in the one from 
Nicaragua, and yellowish-white in the one from Panama. We figure the Nicaraguan 
example. | 
2. Comibzena belisama, sp. n. (Tab. XLIX. figg. 16, 17, ¢.) 
Male. Primaries and secondaries of a bright deep green colour; the primaries crossed about the middle from 
the costal to the inner margin by a rather wide cream-coloured slightly waved line, and with the apex, 
outer margin, and anal angle broadly bordered with dark brown, the fringe dark brown, the costal margin 
edged with brown; the secondaries broadly bordered with cream-colour, and crossed from the apex to the 
anal angle by a wide brown line, the apex itself clouded with brown, the fringe yellowish-brown; the 
underside pale greenish-white, the costal margin of the primaries and the outer margin of the secondaries 
tinged with yellow, the apex and outer margin of the primaries broadly bordered with very dark brown, 
a large dark brown patch at the apex of the secondaries: head and thorax green above, pale brown 
beneath; legs and abdomen pale brown, the latter with three dark brown spots close to the base—one on 
each of the first three segments; antenng brown. LExpanse 1 inch. 
Hab. Panama, Volcan de Chiriqui 2000 to 3000 feet (Champion). 
One epecimen only of this beautiful species has been received, It is allied to 
C. venezuelata, Walk., from which it may be at once distinguished by the dark brown 
margin of the primaries and the differently coloured underside.
