CQMENTA.—CISTHENE, 123 
Hab. Guatemata, Panima (Champion); Panama, Volcan de Chiriqui (Trétsch, mus. 
Staudinger). 
This pretty little species is allied to 7. cingulata, Walk., from which it is distin- 
guished by its bright carmine hind wings. 
CCEMENTA, n. g. 
Primaries long, rather narrow and much rounded at the anal angle; secondaries short and broad, not reaching 
the anal angle of the primaries: head small, palpi very minute ; antenne stout and slightly pectinated ; 
thorax broad and rather flat; abdomen short and thick, only just extending beyond the secondaries ; 
legs short and stout. 
This genus seems allied to Tuina, Walker, from which it differs in its narrower and 
more rounded wings, much smaller palpi, and more robust antenne. 
1. Comenta timon, sp.n. (Tab. VI. fig. 1.) 
Primaries brownish-black ; secondaries bright red, the margins black: head, thorax, and abdomen brownish- 
black, a bluish line on each side of the abdomen; antennee and legs greenish-black. 
Hab. Costa Rica, Irazu 6000 to 7000 feet (Rogers). 
Only a single example of this species was obtained; it reminds one at first sight of 
a Zygcena, but the neuration differs very greatly from that genus. 
2. Cementa morio, sp.n. (Tab. VI. fig. 2.) | 
Primaries uniform bluish-black ; secondaries very dark blue: head, thorax, and abdomen glossy black, the 
sides of the abdomen red; antenns, palpi, and legs black. Expanse 14 inch. 
Hab. Guatemata, Panima in Vera Paz (Champion); Costa Rica, Rio Sucio (Rogers). 
This species seems to be rare: Mr. Champion only captured a single example in 
Guatemala; from Costa Rica two specimens in very poor condition were obtained by 
Mr. Rogers. 
CISTHENE. 
Cisthene, Walker, Cat. ii. p. 533. 
All the species of this genus seem to be rare; I have only received a very few 
examples from our country. The genus was founded by Walker for the reception of a 
species from Venezuela.

Hab. Norra America, Texas (Belfrage) 12.—Mexico, Jalapa (Hoge). 
A single example only of this species has been received from our country. 
2. Cisthene polyzona, sp.n. (Tab. XII. fig. 13.) 
Primaries pale brown, with a creamy-white spot on the costal margin beyond the middle, and two creamy- 
white spots on the inner margin, the first close to the base, the second beyond and nearer the anal angle ;
