{€) parasites, etc., of the si^ecies under consideration, 



(/) lengtli of pupa stage, colour description of pupa, 

 the changes in the aspect of the pupa, when near- 

 ing maturity, etc., 



(g) specimens of the pupa for detailed study, 

 (/i) formation of cocoon and habits of pupation, 

 while every specimen, be it larva, pupa, cast skin or para- 

 site obtained from, say Breeding Cage Xo. 1, will be 

 labelled B.C. Xo 1 and dated. 



Later on, if we are so fortunate as to obtain the imago, 

 the species can be determined and thus all notes, draw- 

 ings, descriptions, etc., can be transferred to a file de- 

 voted to that particular species. 



Even if the name of the species remains for the present 

 unknown, the record will be of great value, as supple- 

 menting observations made by another breeder of the 

 same caterpillar, who may have obtained the larva in a 

 later stage, and has been successful in rearing the adult. 

 Also the time is not so far distant when Ave will be able 

 to determine the famil}^, genus, or even species, from (he 

 cateri)illar, which is one of our aims in this study of the 

 pre-adult stages. 



For the description of the colour pattern, Eidgway's 

 Standard of Colours and Xomenclature should be used.
