PREFACE. 



The object of the present Catalogue is to give a complete 

 list of all the genera and species of Tortoise Beetles 

 (Cassididce) which have been described in various works, 

 and the descriptions of those, not previously noticed in 

 the Author's " Monographia Cassididarum, Holmise, 

 1850-1855," have been added. 



The letters B.M. in the margin show the species now 

 contained in the British Museum, and their absence in- 

 dicates those which are desiderata, and therefore desirable 

 to be procured for the Collection.
