CURCULIONIDAE. 465 



the antennae are not straight, nor the claws appcndiculate as in 

 Ilhycerinae. 



After eliminating the types which seem of sufficient importance 

 to be regarded as having family or sub-family value, there still 

 remains this vast complex, which presents no difficulty in cir- 

 cumscription. It nevertheless comprehends so many diversified 

 combinations and representations of a few simple characters, and 

 under each, so many variations in a few definite directions, that 

 much labor, and very careful observation is necessary to devise 

 a scheme which will enable the genera to be naturally grouped, 

 and easily recognized. 



We believe that the following table will be found sufficient for 

 the proper elucidation of our limited fauna, and perhaps with a 

 certain amount of expansion and modification, may serve as a 

 basis for a general arrangement of the sub-family.
