264 HETEROCERA. 
This handsome insect appears to be fairly common in Central America. Guatemalan 
specimens are much paler in colour than those from most other localities, but in all 
other respects they agree. The examples captured by the late Mr. Forbes at Recife 
are the largest I have seen. . hieroglyphica was found last year by Mr. H. H. Smith 
in various parts of the Mexican State of Guerrero and at various dates between the 
months of June and October. 
. EUDIPNA. 
Eudipna, Walker, Cat. ix. p. 149 (1816). 
Acolasis, Hiibner, Verz. bek. Schmett. p. 256 (1856) (pars). 
Two species were referred to this genus by Walker, both from Surinam. One of 
these extends northwards to the Colombian State of Panama. 
I. Eudipna cedica. 
Phalena Noctua cedica, Cram. Pap. Exot. iv. p. 42, t. 810. f. E*. 
Eudipna cedica, Walk. Cat. ix. p. 150’. 
Hadena (?) cedica, Walk. loc. cit. xi. p. 754°. 
Ophiusa (?) cedica, Walk. loc. cit. xiv. p. 1425 *, 
Hab, Panama, Volcan de Chiriqui (Zrétsch, in mus. Staudinger).—Gutana, Suri- 
nam 1234, 
The specimen from Chiriqui in Dr. Staudinger’s collection agrees perfectly with 
Cramer’s figure. 
. BETUSA. 
Betusa, Walker, Cat. ix. p. 151 (1856), & xv. p. 1671 (1858). 
A single species, Noctua chera, Drury (=B. phasianus, Walk.), from Guiana and 
Brazil, was included in this genus by its describer. We also refer to it Phalena 
amynta, Cram., an insect now known to extend northwards into our region. 
1. Betusa amynta. 
Phalena amynta, Cram. Pap. Exot. iii. p. 100, t. 251. f. E'. 
Hab. Panama, Bugaba 1000 feet (Champion).—Gutana, Surinam 1. 
A specimen from Bugaba, a male, agrees well with Cramer's figure, except that it has 
the antenne pectinated. Cramer’s figure apparently represents a female. 
GISCALA. 
Giscala, Walker, Cat. xv. p. 1671 (1858). 
Walker founded this genus upon a single species from Venezuela and Brazil; the 
second, from Colombia, subsequently added by him, is synonymous with it. This 
insect inhabits the southern part of Central America.
