io8 The Colours of Animals. 



hairy. The caterpillar of the Crimson-ringed But- 

 terfly a species reputed to have been taken in this 

 country is stated to be black, and is not hairy or 

 spiny ; but, as it has red spots and blue tubercles, 

 and the neck is furnished with a yellow forked 

 appendage, it is probably .sufficiently protected. 

 The larva of the Swallow-tail Butterfly is also 

 marked with black, and provided with strongly- 

 scented tentacles, which probably serve as a pro- 

 tection. 



Again, there are 16 brown species, and of these 

 seven are hairy or spiny. 



7. Red and blue are rare colours among cater- 

 pillars. Omitting minute dots, we have six species 

 more or less marked with red or orange.* Of these, 

 two are spiny, two hairy, and one protected by scent- 

 emitting tentacles. The orange medio-dorsal line 

 of the Bedford Butterfly f is not very conspicuous, 

 and has been omitted in some descriptions. Blue 

 is even rarer than red ; in fact, none of our butter- 

 fly larvae can be said to exhibit this colour. 



8. Now let us turn to the moths. I have taken all 

 the larger species, amounting to rather more than 

 I2o;j out of which 68 are hairy or downy; and 



* These are A. aglaia, V. antwpa, N. lucina, C. atsw, P. cratagi, 

 and P. maehaon. 



t Cupido alsus. 



J The Htpialida, Zeuzerida, and Sesida have been omitted, 

 because these larvae are all internal or subterranean feeders, and are 

 devoid of any striking colour.
