Of this very beautiful and extremely variable species, it 

 has been necessaiy to give specimens under several dif- 

 ferent aspects of colouring. The predominant colouring 

 is deep rose, variously interrupted with bands of pale yel- 

 low, marked with regular oblique black bands ; but these, 

 as it may be seen in Fig. 88 k, are sometimes absent, 

 while in other specimens, as at Fig. 88 i, the black bands 

 are conspicuous, and the rose colouring is wanting.
