which is the origin of the scientific name, is lost in 

 the long clothes of modern England ; but the sketches 

 given below show sufficiently what is meant. The one 

 is a magnified chrysalis not, perhaps, that in which 

 the likeness to a child in swaddling-clothes is strongest 

 taken from a sketch reproduced in Professor Duncan's 

 book from one by Reaumur, who was as eminent as a 

 naturalist as in other branches of science, and kept 

 insects in his gardens to observe their habits and 



changes the forerunner by a hundred and fifty years 

 or more of Sir John Lubbock and his fellows. 



The sketch at the side of the chrysalis is 'Nurse 

 Gladstone's Baby,' borrowed from Punch's cartoon of 

 the 25th August 1883. 



The name for a Caterpillar larva, a mask is in- 

 tended, of course, to suggest the idea of the perfect 

 insect disguised for a time in a form very unlike its 

 own.
