Bibliographical Bulletin, 203 



tic index to Mr. Cuitis's British Entomology, a reference being given 

 to every genus illustrated in that valuable and splendid work, which 

 now contains more than 700 beautiful and accurate coloured repre- 

 sentations of insects, and nearly as many of indigenous plants. The 

 numerous additions that have been made to our British collections 

 of late having been embodied in the present edition, it is far the most 

 complete catalogue of the present day, comprising nearly 15,000 

 British species, and cannot fail to be highly serviceable to those for 

 whose use it is designed.
