when full grown ; we may find a few scattered 

 hairs by searching with a lens, and here and there 

 a minute tubercle, or a smooth and shining wart ; 

 in some species the front part of 

 the body is swollen and furnish- 

 ed with striking eye-spots ; at 

 birth, however, the body is al- 



* 



wa ^ s Perfectly cylindrical and 

 supplied with several prominent 



^^ Qf brist l e . be aring tllber- 



cles, one tubercle to a segment in each row, and 

 one row in the middle of the sides more conspic- 

 uous than the others. 



Instances have been given in every one of the 

 larger groups of butterflies to show the universal- 

 ity of this feature in the development of the cater- 

 pillar ; many of the changes are gradual in their 

 appearance, as shown by the accompanying fig- 

 ures [Fig. 46] of the spines of the caterpillar of 

 Harris' s butterfly (Cinclidia Harrisii) 

 [Fig. 47] at different stages, where, it 

 will, be seen, they grow more compli- 

 cated with advancing life ; or they 

 may be seen better still in those of 

 the caterpillar of the Painted Lady 

 (Vanessa cardui), as shown in Fig. 

 41. where the spines of each stage are shown ; but 

 the more important changes between the different 

 stages of a caterpillar's life occur at the first 

 moulting ; that is, those features of the young
