mens as beyond determination. But still the writing of de- 

 scriptions continued, and it had to^in fact, for the smaller chestnut 

 weevil had not yet received a name. 



In 1909 Chittenden, after publishing the 1904 Yearbook paper 

 and studying what Brooks had found out, as well as the great 

 accumulation of material in Washington, discovered and pointed 

 out Casey's error in regard to nniformis and named five, to him, 

 definite forms mostly among the short-beaked acorn species, 

 each associated with its food plant. Unfortunately he followed 

 Horn in misapplying Say's rectus to the smaller chestnut weevil 

 so that it once more escaped being named ; and his orthorhynchiis 

 becomes nearly a synonym of rectus. His Floridian parvidens 

 also seems uncomfortably close to Casey's Floridian hiimeralis, 

 to which he seems to have paid little attention. He named how- 

 ever haculi for the gray, and pardalis for the spotted, short- 

 beaked acorn weevils to join Hamilton's confusor, with its 

 fasciate elytra, as names for the short-beaked acorn weevils. 

 One result of Chittenden's paper was to stimulate Casey to 

 another attempt and in 19 10 the Canadian Entomologist published 

 Casey's descriptions of no less than twenty-two new species and 

 subspecies. The smaller chestnut weevil was named this time 

 not once but four times, for algonquinus, setosicornis, macilentus, 

 and perexilis, all appear from the characters given to be closely 

 related and however distinctly separable as taxonomic units by 

 Casey's description, to be all possessed of the characters ascribed 

 to rectus by preceding authors, in their erroneous endeavor to 

 fasten that^ name on the smaller chestnut weevil. Algonquinus 

 being the first given is here used for that species. 



In this paper of Casey's, names for the short-beaked acorn 

 weevils are as greatly multiplied as are those for the smaller 

 chestnut weevil. From his standpoint, that of dealing with 

 taxonomic units as exemplified by cabinet series of one or more, 

 this course is not only justifiable, but the only course consistent 

 with the recognition of Chittenden's names as valid. The short- 

 beaked acorn weevils cover all the United States as far as
