tnent under which they are concealed : then he is to take the leaf 

 to which they have fixed themfelves, and put it under a glafs until 

 the imago is difclofed, which will be in ten or twelve days. 



I fliall begin with fome preliminary obfervations, that extend to 

 all the fpecies which I have had an opportunity of obferving. 



The larvse of this genus are all furrounded with marginal radii, 

 and thefe radii are ufually ciliated, fo as to give the infect, fub lentey 

 a very fingular and elegant form. They are alfo remarkable for 

 being merdigerous, and for this purpofe are furnifhed with fome long 

 ftifFbriftles juft above the anus, upon which they dcpofit their ex- 

 crement; and thus form a covering, not indeed very delicate, which 

 I imagine ferves to conceal them from the birds, and which I re- 

 member that accurate obferver Reaumur noticed in the C. viridis. 

 This fhield, by means of the above-mentioned briflles, the little 

 animal has the power of elevating or depreflingj fo that fometimes 

 it (lands at a right angle with the body, and at others is fo clofely 

 applied to it, as to conceal the infe£l from any but an entomological 

 eye. 



In the pupa flate, the head of thefe infe6ls is enclofed in a fhield, 

 fringed with marginal radii. The abdomen is radiated like that of 

 the larva, and is furnifhed with iour fpiracula on each fide. It fixes 

 itfelf by means of the exuvia of the larva. The imago, when it 

 difclofes itfelf, makes its way through a tranfverfe fifTure of the 

 .fhield.
