Appendix. 



[Here follow the remarks on the habits of the larvae 

 in connection with their colours, &c., which have already 

 been quoted in illustration of the use of the spiny pro- 

 tection (note 5, p. 293). From these facts the author 

 draws the conclusion that the form-relationships of the 

 caterpillars depend rather upon their mode of life than 

 upon their blood-relationships, assuming the latter to be 

 correctly expressed by the arrangement of the imagines 

 at present adopted.]

Figs. I 4. Pupae of Acraa Thalia; Heliconius Eucrate ; Eueides 

 Isabella, and Colcenis Dido ; life size. 



" A glance at the above figures of the pupae of Heli- 

 conius Eucrate (Fig. 2), Eueides Isabella (Fig.* 3), and 

 Colcenis Dido (Fig. 4), will show how great are the 

 differences between these pupae as compared with the 

 close form-relationship of all the Maracuja butterflies, 

 and with the no less close resemblance of their larvae. 

 A family which comprised three such dissimilar pupae 

 would also be capable of including that of* Acrcea 

 i).
