North American Rhynchophora. 



231 



a vastly greater number of described species than that of North 

 America. If, therefore, we consider the probability that the 

 family is equally well represented in the two continents, it should 

 not be wondered at if every independent collection made in our 

 south-western territories for some time to come consist for the 

 most part of nondescript material. 



The family having been recently reclassified and its component 

 parts conveniently described, the task of interpolating these new 

 forms becomes a comparatively easy one. 



Several Mexican species before me are not included in the 

 present memoir, as the family will shortly be treated of in the 

 Biologia Centrali- Americana by Dr. Sharp, and any such de- 

 scriptions would only tend to increase the diflSculty of this great 

 undertaking.

The following is a list of the new species here described. The 

 measurements in the Rhynchitidae are taken from the anterior 

 margin of the eyes to the extremity of the body, while through- 

 out the Otiorhynchidae and Sitoninae they include the entire body 

 from the tip of the beak in its natural position.
