The object of the pr&sehfr^atalogue is to give & Complete List of 

 all the genera and species ..of Tlemipt'era' Heteroptera known to 

 exist in the collections of European and American Entomologists. 

 The letters a, b, c, &c, after the species, denote the specimens now 

 contained in the British Museum, followed by the habitat and the 

 mode in which each of them was obtained ; aud the absence of 

 these letters indicates the species which are desiderata, and there- 

 fore desirable to be procured for the collection.
