INTRODUCTION. 



The principal object of the present Catalogue has been to 

 give a complete list of the specimens of Neuropterous Insects 

 contained in the collection of the British Museum, indicating 

 at the same time the peculiarities of each, as regards variation 

 of character, locality, and the source from whence it has been 

 derived. With this view, the different individuals of each 

 species contained in the collection are indicated by the letters 

 a, b, c, &c, following the name of the species and its syno- 

 nymes, and the description, if it appeared to have been before 

 undescribed. 



This part of the Catalogue of Neuropterous Insects has 

 been prepared and the new species described by Mr. Fbancis 

 Walker, so well known for his attention to this order of 

 Insects. 



The continuation is in hand, and will follow as soon as it is 

 ipleted.
