THE PUPA OR CHEY8ALI8

In colour they are equally variable. Some are beautifully 

 tinted with delicate shades of green, some spotted on a light ground, 

 some striped with bands more or less gaudy and distinct, but 

 the prevailing tint, especially 

 among the moths, is a reddish 

 brown, often so deep that it is 

 almost a black. 



As a rule there is no 

 marked resemblance between 

 the different stages of the 

 same insect. Thus, a bril- 

 liantly coloured caterpillar 

 may change to a dull and 

 unattractive chrysalis, from -p IG

or moth that partakes of the 

 colours of neither. But in a 

 few cases there are colours 

 or other features that remain 

 persistent throughout the three stages, or show themselves pro- 

 minently in two. 



An interesting example in point is that of the Magpie or Currant 

 Moth (page 279). The caterpillar of this moth is cream-coloured, 

 with orange stripes along the sides, and very bold black markings 

 down the back. The chrysalis, which is at first entirely yellow, 

 afterwards turns black with the exception of some yellow trans- 

 verse bands. Then, the moth exhibits the same colours as these 

 two earlier stages, with the 

 same degree of boldness; 

 for its pale cream-coloured 

 wings, tinted with patches 

 of yellow, are marked with 

 numerous deep black spots. 

 Thus, in this case, we find 

 the same general character El p UpA 84 ' 7

Another interesting ex- 

 ample, though not so striking as the last, is to be found in the case 

 of a group of moths known as the Liparidce. The caterpillars of 

 these are remarkable for their very hairy bodies, often ornamented
