BY R. H. PETTIT. 



Bulletin No. 251. 



INTRODUCTORY. 



The present bulletin deals with a few of the insects of 1907, either 

 new to our state or of special interest just at this time. 



The writer wishes to emphasize the fact tliat he is always glad to 

 receive specimens of insects or of their work, and in return to name 

 them when possible and to give advice as to methods of control. Send 

 specimens when possible, in tight, tin boxes with few if any holes. 

 Send to the Entomologist of Experiment Station. 



The writer also wishes to express his thanks to Mr. E. J. Kraus, 

 who was student assistant during the summer of 1907 and whose help 

 in the field has been of great value. Some of the photographs were made 

 by Mr. Kraus and some by the writer.
