fctJSCHEMONtD^E. 33 



inches) ; wings densely clothed with large scales, and, especially 

 towards the base, with long hair ; fore-wings rather long, more 

 or less pointed at the tips ; hind-wings rounded, the frenulum 

 absent. Cells simple, closed, very long, the two lower sub- 

 median nervules rising in the male very near the base on the 

 fore-wings. Body very stout. Antennae strongly clubbed or 

 thickened at the extremity. 



Range. Southern United States, to Mexico and Costa Rica. 



Habits. Flight diurnal, rapid, darting, and sometimes tower- 

 ing. They frequent open places, and generally settle near the 

 ground. At rest they fold their wings vertically. 



There are but two genera of this curious Family known. They 

 include a few brown species with tawny or yellowish markings. 

 In McgathymO) Scudder, the antennae have a large knob-like 

 club, and in Acentrocneme, Scudder (sEgiale, Felder), there is 

 a long thickening before the tip, as in Castnia. 



FAMILY II. EUSCHEMONID^E. 



This Family may be suggested to include a very curious 

 Australian species, Euschemon rafflisice (Macleay), respecting 

 which authors differ, as to whether it is to be regarded as a 

 Butterfly or a Moth. It measures upwards of two inches across 

 the wings, which are dark brown. The fore-wings are rather 

 narrow and pointed, and the hind-wings rounded. There is a 

 narrow oblique yellow stripe on the fore-wings, and there aie 

 two large yellow patches on the h ; nd-\vings. The hairy palpi 

 and the tip of the abdomen are scarlet. The antennae are 

 very long, much thickened, and slightly hooked at the tip. 

 The cells are simple, and closed ; but the presence of a frenu- 

 lum is a character of so much importance as to remove it from 

 the typical Hesperiidce. Nothing appears to be recorded 

 respecting its habits and metamorphoses.
