310 . HETEROCERA. 
underside of the primaries dusky, with the white band very indistinct, that of the secondaries as above : 
head and front of the thorax white, the rest of the thorax and the abdomen blackish-brown ; the antenne 
black. Expanse 1 inch. 
Hab. Mexico, Presidio (Forrer). 
DROBETA. 
Drobeta, Walker, Cat. xv. p. 1755 (1858). 
Drobeta differs from most of the allied genera in the form of the primaries. A 
single species only, from Venezuela, was included in it by Walker. We have now to 
record four from Central America, two of which are described as new. 
1. Drobeta exscendens. 
Drobeta exscendens, Walk. Cat. xv. p. 1755". 
Hab. Panama, Volcan de Chiriqui 4000 feet (Champion).—V ENEZUELA (Dyson 1). 
The single specimen received from Chiriqui agrees very nearly with the type in the 
National Collection. 
2. Drobeta delectans. 
Dianthecia (?) delectans, Walk. Cat. xi. p. 505°. 
Hab. Guatemaa, Volcan de Atitlan 3000 feet (Champion); Panama, Volcan de 
Chiriqui (Ribbe, in mus. Staudinger).—Amazons, Santarem 1. 
This species seems to me to be better placed in Drobeta, it being, without doubt, 
closely allied to D. exscendens. The specimen received from Guatemala is considerably 
paler than the type, though not otherwise differing from it. 
3. Drobeta tiresias, sp. n. (Tab. XXIX. fig. 1.) 
Primaries dark silky brown, clouded with very dark brown near the apex from the costal to the outer margin, 
with two narrow dark brown lines crossing the wing close to the base from the costal to the inner margin, 
several faint brown lines crossing beyond the cell from the inner margin to the dark brown marking near the 
apex, and a dark brown spot at the anal angle ; secondaries dark brown, with a pale brown streak along 
the inner margin, the fringe pale brownish-white: head and thorax pale brown, the collar dark brown ; 
the abdomen, antenne, and legs pale brown. Expanse 1,4, inch. 
Hab. GuateMaLa, Las Mercedes 3000 feet ( Champion). 
4. Drobeta ithaca, sp.n. (Tab. XXIX. fig. 2.) 
Primaries pale brown, with darker brown lines crossing from the costal to the inner margin and several TOWs 
of small lunular-shaped white spots crossing the wing beyond the middle, the fringe alternately dark 
and light yellowish-brown ; secondaries glossy dark blackish-brown, with the fringe pale fawn-colour : 
head, thorax, and abdomen pale brown, the anal tuft black, the antenne pale brown, the legs brown. 
Expanse 1,8, inch. . 
Hab, Panama, Bugaba 800 to 1500 feet (Champion).
