THE MOTHS. LEPIDPOTERA HETEROCERA. 



Flight nocturnal or crepuscular, more rarely diurnal. 

 Antennce of very various shapes, but mc^t frequently fiUform, 

 serrated, or (especially in the males) more or less pectinated 

 or plumose ; rarely thickened at or beyond the middle, in 

 which case they are sometimes hooked ; still more rarely 

 thickened into a club at the extremity. Labial and maxillary 

 palpi variously developed. A frenulum (or very rarely a 

 jugum) generally present. Wings occasionally more or less 

 aborted, especially in the females. 



The first two families are of rather doubtful position, some 

 authors regarding them as Hesperiidce^ and others as more 

 nearly allied to the Castniidce. 



For further information respecting Moths in general, I refer

FAMILY I. MEGATHYMID^ (GIANT SKIPPERS).

 pressed in the middle ; not unlike an inverted pudding-basin 

 in shape. 



I^arva. — With sixteen legs, white, sparsely clothed with short

 the open. 



Pupa. — Cylindrical, the several coverings well marked. 

 Abdomen with a row of very small spines on the back. The 

 pupa is found in the long galleries formed by the larva. 



Ima^o. — Of moderate size (expanding from two to three
