tincta) fusco-nigris ; fascia arcuata a basi ad angulum analem extensa, macula subquadrata apud cellule

Hab. Mexico! (Sallé), Atayac (Hedemann, Mus. Vindob.), Oaxaca (Deppe, Mus. Berol., 
Fenochio) ; Guatemaua, Retalhuleu, Duefias, Chuacus, San Gerdnimo (F. D. G. & 0. 8.), 
Chisoy valley and Polochic valley (Hague); Costa Rica (Van Patten ?), San Francisco, 
Trazu (Rogers). 
Originally described from Mexican specimens!, D. klugi has since been found in 
numbers in the southern parts of that country ; and it would appear to be equally common 
in Guatemala, where it is perhaps the most abundant of all J¢homiine up to an elevation 
of about 5000 feet. Inthe mountainous parts it is more frequently met with than in the 
low-lying tropical forests; and this may account for its not being found in Nicaragua, 
whereas in the mountains of Costa Rica it again appears. It is nearly allied to D. relata ; 
and some signs of connecting links between the two are not wanting in Costa Rica, where 
both are found.

3 D. klugi similis, sed alis obscurioribus, anticarum basi fere nigra, posticarum margine externo angulum 
apicalem versus latiore, area interna proxima fere pellucida, distali fulvescente, antennis flavis basi nigris. 
@ maculis anticarum magis distinctis et area posticarum interna unicolori rufa. 
Hab. Nicaracua, Chontales (Belt, Janson); Costa Rica (Van Patten), Caché 
(Rogers); Panama, Chiriqui and Calobre (Arcé). 
This is a close ally of D. klugi, the place of which it seems to take, to some extent, 
in the southern parts of Central America, where it would appear to be as common as 
D. klugi is in Mexico and Guatemala. ‘The chief distinctions between the two consist 
in the darker colour of the wings, and the smaller size and the greater distinctness of 
the pale yellowish spots of the primaries. It is a somewhat smaller insect, and has, in 
the male, more fulvous colour on the outer half of the inner area of the secondaries. 
Our descriptions are based upon Costa-Rica examples, the male being the type of the 
species, the female a Caché specimen.
