12 BRITISH BUTTERFLIES. 



This is called the CHRYSALIS or PUPA state. 



Pupa is a Latin word, signifying a creature swathed, 

 or tied up ; and is applied to this stage of all insects, 

 because all, or some, of their parts are then bound up, 

 as if swathed. 



The term Chrysalis is applicable to butterflies only, 

 and, strictly, only to a few of these Chrysalis 1 being 

 derived from the Greek xpucroe (chrysos), gold in 

 allusion to the splendid gilding of the surface in. certain 

 species, such as the Vanessas, Fritillaries, and some 

 others. 



In the older works on entomology we frequently meet 

 with the term Aurelia applied to this state, and having 

 the same meaning as chrysalis, but derived from the 

 Latin word Aurum, gold. 



Here the reader is again referred to Plate I. for a 

 series of the principal forms assumed by the chrysalides 

 of our native butterflies, and as these for the most part 

 represent the next stage of the caterpillars previously 

 figured, an opportunity is afforded of tracing the insect's 

 form through its three great changes ; the whole of the 

 butterflies in their perfect state being given in their 

 proper places in the body of the work. 



The complicated and curious processes by which 

 various caterpillars assume the chrysalis form, and 

 suspend themselves securely in their proper attitudes, 

 have been most accurately and laboriously chronicled
