This Work, which is intended to contain systematic Descriptions of all the Insects collected 

 by Dr. Horsfield in Java, will be published in Numbers. The Species will be arranged, as 

 nearly as possible, according to their natural affinities; and in order to make this, the 

 important part of the Science, more clear, the Descriptions will be interspersed with such 

 leading observations on the economy and anatomical structure of the Families, as may, it is 

 hoped, render the work interesting to Naturalists in general, as well as to the Entomologist. 



The plan of the Author, however, will be best understood on a perusal of the first Number. 

 The second Number is now in progress for publication, and will contain the whole of the 

 Coleoptera having Iuliform Larvae. 



The Insects described are arranged in the Museum of the Honourable East-India Company, 

 where they may be inspected under the regulations established at their Library.

In this Work will be given Figures and Descriptions of the more remarkable new or imperfectly known 

 Plants, contained in a Herbarium of Two Thousand Species, collected in the Island of Java, by Dr. Hors- 

 field, and deposited by him in the Museum of the Honourable East-India Company. 



The size of the Work will be a large Quarto. Each Plant will be figured on a separate Plate ; the 

 subjects selected will not exceed One Hundred ; and the Work will appear in Numbers, containing 

 Eight Plates. 



Both the Engravings and Descriptions are in a state of forwardness, and it is proposed to publish the first 

 Number early in the course of the present season.
