Descriptions of Curculionid.e; by Francis P. Pascoe, F.L.S., 

 &c. Part I. 



The CurcHlionidce described in the followiug pages are selected 

 from a large number of unnamed species in my collection. 

 There are so many forms differentiated by characters so slight 

 and indefinite, that it is a matter of exceeding difficulty to 

 determine, in some cases, even the genera to which they respec- 

 tively belong, and, in other cases, to decide how far they may 

 lie within the range of individual variation. There are, however, 

 a sufficient niimber of fairly well-marked forms to render their 

 publication desirable. Tropical America — so rich in species — 

 is excluded from these pages, as it furnishes the material of a 

 series of papers I am now publishing in the Annals and Maga- 

 zine of Natural History. 



The followiug is a list of the species aud their subfamilies 

 described in the present part.
