LEPIDOPTERA HETEROCERA. 1511 
Body very thick. Palpi generally very short, not visible, of 
moderate length in some species. Antenne serrated or pectinated, 
longer than the thorax. Abdomen extending more or less beyond 
the hind wings. Legs stout, pilose; hind tibie with four short 
spurs. Wings rather long, hardly broad. Fore wings hardly con- 
vex along the costa, rounded at the tips, very oblique along the ex- 
terior border ; first and second inferior veins almost contiguous at 
the base ; third near the second and about thrice further from the 
fourth. Female.——Oviduct serrated. 
The few species of this genus differ much from each other in 
the length of the palpi, in the antenne and in other characters, but 
have great general mutual resemblance, and are therefore not 
divided from the genus of the typical species C. ligniperda.
