Family COCHLIDIIDiE. 



These are moderate-sized or small moths with rather plump and shaggy 

 bodies, retracted head, weak tongue, and often pectinated antennae. The wings 

 are short and broad, often very densely scaled, the colors usually brown, often 

 with green contrasts. 



The larvie are rather more easily recognized than the adults, from their slug- 

 like character. The feet are in large part obsolete, while the underside is 

 flattened, soft and fleshy, the larva using the entire under surface in walking. 

 Another peculiarity is found in the poisonous character of the spines clothing 

 these caterpillars, the tips being very finely pointed, easily detachable and 

 extremely irritating when they are imbedded in the flesh. In some cases they 

 cause serious swellings. 



Dr. Dyar says concerning these larvae that most of them are feeders on any 

 smooth-leafed tree, and this may be assumed unless special food plants are 

 mentioned or unless cultivated species are injuriously affected.
