THE LIPARIANS. 365 



when at rest, is almost exactly like that of some of the 

 Lithosians ; but the other kinds of Lophocampa do not 

 cross the inner edges of the Aviniis ; and the bodies of all 

 of them are much thicker and more robust than those of 

 the Lithosians. 



The third group or family of Bombyces may be called 

 Liparians (Liparid^e*). Of the moths bearing this name, 

 the females have remarkably thick bodies, and are sometimes 

 destitute of wings, while the males are generally slender, and 

 have rather broad wings. Their feelers are very hairy, and 

 for the most part are rather longer than those of the Arctians. 

 Their tongues are very short, and invisible or concealed. 

 Their antenna? are short, and bent like a bow, and doubly 

 feathered on the under side, the feathering of those of the 

 males being very wide, and of the females mostly narrow. 

 When at rest, these moths stretch out their hairy fore legs 

 before their bodies, and keep their upper and lower wings 

 together over their backs, sloping a very little at the sides, 

 and covering the abdomen like a low or flattened roof. The 

 females, even of those kinds that are provided with wings, 

 are very sluggish and heavy in their motions, and seldom 

 go far from their cocoons ; the males frequently fly by day 

 in search of their mates. The caterpillars of most of the 

 Liparians are half naked, their thin hairs growing chiefly 

 on the sides of their bodies ; the warts which furnish them 

 being only six or eight f in number on each ring; and they 

 have two little soft and reddish warts (one on the top of the 

 ninth, and the other on the tenth ring), which can be drawn 

 in and out at pleasure. Some of them have four or five 

 short and thick tufts, cut off square at the ends, on the top 

 of the back, two long and slender pencils of hairs extending 

 forwards, like antennse, from the first ring, sometimes two 



* From Liparis^ more properly Liparus, the name of a genus of moths belong- 

 hig to this group. This name means fat or gross, and was probably assigned to 

 the genus on account of the thickness of the bodies of some of these moths. 



t The Arctians have ten or more warts on each ring.
