Phalena amynta, Cramer (Pap. Exot. iii. p. 100, t. 306. f. C), may be a synonym 
of this species, but the figure is so badly drawn that it is impossible to say with 
certainty. If this should prove to be the case, the name amynta cannot be retained 
for the insect, Cramer having also applied it to a very different species on t. 251. f. E. 
The type of Giscala semiviridis, Walker, is now in my possession, and upon comparing 
it with that of G. guadricolor in the National Collection I find that the two are con- 
specific. The sexes are very similar. 
Subfam. APAMINA. 
Group GORTYNIDES. 
GORTYNA. 
Gortyna, Ochsenheimer, Schmett. Eur. iv. p. 82 (1816); Walker, Cat. ix. p. 154. 
Ten species were originally included in this genus by Walker, four from Europe, 
five from North America, and one from the Cape of Good Hope; and he subsequently 
added one from Mexico. 
1. Gortyna ditissima. (Tab. XXVI. fig. 9.) 
Gortyna ditissima, Walk. Cat. xi. p. 716°. 
Hab. Mexico (Sallé1); Guatemata, Las Mercedes 3000 feet, Volcan de Atitlan 
2500 to 3500 feet (Champion). 
Guatemalan specimens agree perfectly with Walker’s type in the National Collection. 
Our figure is taken from an example from the Volcan de Atitlan. 
NAESIA. 
Nesia, Walker, Cat. xv. p. 1741 (1858). 
Walker founded this genus upon an insect from Venezuela; this is now known to 
us from Costa Rica, whence we have also received specimens of the second species here 
described. Ne@sia appears to be very closely allied to Gortyna, but to differ in the 
third joint of the palpi being slightly longer, the primaries not quite so much rounded, 
and the abdomen clothed with tufts of long hairs.
