LEPIDOPTERA. 263 



tennce; its fore wings are deep yellow, crossed by about six 

 white bands, on each of which is a row of black dots ; the 

 hind wings are scarlet red, with an irregular border of black 

 beiiind ; the body is white, and the thorax is dotted with black. 

 It expands from one and a half to one inch and three quarters. 

 Its time of appearance here is from the middle of July till the 

 beginning of September. The caterpillar is unknown to me ; 

 but Drury states that he was informed it was of the same color 

 as the fore wings of the moth, (that is yellow and white dotted 

 with black), and that it feeds upon the blue lupines.* The 

 European De'iopeia pulcheUa, which is very much like our spe- 

 cies, feeds, in the caterpillar state, on the leaves of the mouse- 

 ear, Myosotis arvensis and palustris ; and it is probable that 

 ours may be found on plants of the same kind here. 



Some of the large and richly colored Lithosians resemble, 

 in many respects, the insects in the next family, called, by the 

 English, tiger and ermine moths. The caterpillars of most of 

 these tiger-moths are thickly covered with hairs, whence they 

 have received the name of woolly bears, and the family, in- 

 cluding them, that of Arctiad.e, or Arctians, from the Greek 

 word for bear. The Arctians, or tiger-moths, have shorter and 

 thicker feelers than the Lithosians ; their tongue is also for the 

 most part very short, not extending, when unrolled, much be- 

 yond the head; their antennte, with few exceptions, are doubly 

 feathered on the under side ; but the feathering is rather nar- 

 row, and is hardly visible in the females ; their wings are not 

 crossed on the top of the back,f but are roofed or slope down- 

 wards on each side of the body, when at rest ; the thorax is 

 thick, and the abdomen is short and plump, and generally 

 ornamented with rows of black spots. Their fore wings are 

 often variegated with dark colored spots on a light ground, or 

 light colored veins on a dark ground ; and the hind wings are 

 frequently red, orange, or yellow, spotted with black or blue. 

 They fly only in the night. Their caterpillars are covered with

tTo this character there is an exception in the Lophocampa teasellaris, the 

 wings of which are closed like those of Lilhosia quadra.
