 But many extensive regions are as yet altogether unexplored, and 

 a complete System of Lepidopterous Insects founded on their meta- 

 morphoses is reserved for some future Entomologist provided with 

 more ample materials than have as yet been brought together : my 

 only object in the present work is to contribute the result of my 

 labours in the Eastern Islands. 



Deeply impressed with the importance and necessity of an ac- 

 curate knowledge of Lepidoptera in all stages of their existence, I 

 devoted, during several successive seasons, all the means at my 

 command to the investigation of Javanese Lepidoptera ; and it may 

 be not out of place here to give a brief extract from the Descriptive 

 Catalogue above mentioned, of the method pursued by me. " I 

 lived at this time at Surakarta, a province in the interior, be- 

 longing to the native princes. I was amply provided with every 

 convenience and facility for preserving what I had collected. 

 Several draughtsmen had likewise been trained, under my super- 

 intendence, for botanical delineations ; and the skill they acquired 

 in those, soon fitted them for the annulose department. I was, 

 therefore, enabled to enter upon a history of the Metamorphoses 

 of Javanese Lepidoptera, a design which had long engaged^ my 

 anxious solicitude. Although I did not, at this period, so fully 

 conceive the paramount necessity of an acquaintance with the 

 Metamorphoses of Lepidoptera, towards the establishment of a 

 natural arrangement, as I have been led to do in later periods, 

 yet I was so strongly impressed with its essential importance in 

 attempting a complete history of Insects, that I commenced with 

 a fixed determination to prosecute the inquiry with unremitted 

 industry and zeal, to collect all the larvtc of Lepidopterous Insects 

 which I might possibly obtain, and to trace them through tlie
