158 HETEROCERA. 
This genus will include three species from the southern parts of Central America and 
Colombia. 
1. Astyochia crane, sp.n. (Tab. XIV. figg. 18,192.) 
Male. Primaries and secondaries uniform silky whitish hyaline, the costal apex, and the outer and part of the 
inner margins, bordered with black, the secondaries bordered with black from the apex round the outer 
margin to near the base, a black band at the end of the cell on the primaries, in some specimens the discotdal 
nervules black: head, antenne, and palpi black ; thorax and abdomen dusky white ; legs brownish black. 
The female differs from the male in not having the black band at the end of the cell on the primaries, and 
in the black margins being narrower. Expanse, ¢ 1 inch, 9 14 inch. 
Hab. Panama, Volcan de Chiriqui 2000 to 4000 feet (Champion). 
On the volcano of Chiriqui this is a common insect; it is found in the denser parts 
of the forest. I have a very large series of specimens before me showing but very little 
variation. 
2. Astyochia fessonia, sp. n. 
Male. Form of A. crane; primaries and secondaries bluish hyaline, the veins and margins of the wings black, 
the black band at the end of the cell crosses from the costal to the outer margin: head, thorax, and 
abdomen greyish black ; antenne, palpi, and legs black. The female only differs from the male in not 
having the veins so deeply marked with black. Expanse ¢ 9 1 inch. 
Hab. Costa Rica, Irazu 6000 to 7000 feet (Rogers).—Cotomsta, Bogota (Birchell, 
mus. D.). : 
3. Astyochia faula, sp.n. (Tab. XIV. fig. 28.) 
Primaries pale brownish drab, the veins slightly darker in colour and somewhat hyaline near the base, the 
costal margin and a spot at the end of the cell darker brown; secondaries uniform pale brownish drab, 
the veins darker, the underside the same as above: head, thorax, and abdomen silky brown; antenne 
and palpi black ; legs brownish black. The female similar to the male, but paler in colour. Expanse 
13 inch. 
Hab. Panama, Volcan de Chiriqui (Champion). 
A common species in the State of Panama. 
TITHRAUSTES, gen. nov. 
Head moderately large; palpi erect, rather long and slender; antennez long, deeply pectinated ; eyes large 
and prominent; proboscis short; thorax and abdomen stout, the abdomen extending beyond the wings ; 
legs long, slender, and not clothed with hair; primaries long and rather broad; secondaries long and 
much rounded at the apex. 
This genus is allied to Astyochia; it will contain four species from Central America. 
1. Tithraustes hemon, sp. n. (Tab. XIV. fig. 20.) 
Primaries pale brown, slightly hyaline near the base, a large round spot at the end of the cell, and two small 
spots beyond close to the outer margin, dusky white; secondaries pale blackish brown, with a large central 
dusky white spot: head, thorax, and upper side of the abdomen dark brown, the abdomen dusky white 
beneath ; antenne black ; palpi brown; tegule bright orange; legs brownish black on the outer fside, 
whitish beneath. Expanse 12 inch. 
Hab. Panama, Volcan de Chiriqui (Champion).
