198 THE BUTTERFLY VIVARIUM. 



pillar forming with great regularity a cocoon of egg- 

 like form. This fine large Moth differs considerably 

 in the colouring of the males and the females, the 

 males having the base of the wings, next the body, 

 of a rich dark brown, in which is a white spot ; 

 beyond which is a broad border, reaching to the 

 edge, of bright yellowish ochre ; the female is still 

 larger, but of paler colouring, exhibiting only two 

 shades of fawn, and the antenna} are simple, in- 

 stead of being pectinated like those of the male. 



If the collector should be fortunate in securing a 

 female of this species, he may capture as many males 

 as he wishes; for on going out with the captive 

 female into any locality in which these Moths are 

 found, the males will immediately appear, some- 

 times in considerable numbers, and are occa- 

 sionally so bold that they will follow the box 

 containing the female even into the pocket of the 

 collector, or into any trap he may contrive for their 

 capture. Then there is Lasiocampa Rubi, the Pox 

 Moth, of similar but more ruddy tone and colouring, 

 the Caterpillar of which forms the long semi-trans- 

 parent cocoon previously described. This Caterpillar 

 is clothed with rich foxy fur, the joints of the 

 segments, when stretched out, looking like inter- 

 stices of black velvet.
