No. 22.] HYMENOPTERA OF CONNECTICUT. 1 3 



reproduced in Part I of this work,* the state of Connecticut is 

 chiefly in the areas designated respectively as AUeghanian, or Hu- 

 mid Transition, possessed of vegetation and animals such as pre- 

 vail in New York, Massachusetts, Rhode Island, and similar reg- 

 ions ; and Carolinian, or Humid Upper Austral, possessed of veg- 

 etation and animals such as prevail in southern New Jersey. The 

 latter area includes only the coastal margin of the state and the 

 region extending for some distance up the valleys of the rivers. 

 Besides these, there is in the more elevated northern sections of 

 the state a touch of Canadian life, which is to be found at its 

 best where the spruce tree flourishes. The distribution of the 

 different species in the following pages is in some cases given 

 in the above terms for the sake of brevity. 



Finally, the succeeding pages are an endeavor to present to 

 the people of Connecticut the ants, wasps, bees, etc., or Hymen- 

 optera of their state, in such a way that those who so desire may 

 find out the name of any species so far known to occur in the 

 state and such facts about the same as are of general interest. 



It must be remembered that this is the first attempt along these 

 lines ; and, considering that every day's systematic collecting in the 

 state is almost sure to reveal a species new to the state, and quite 

 likely to furnish a species entirely new to science, the short- 

 comings of this treatise are certainly inevitable. It is to be 

 hoped that this treatise will stimulate an interest in these insects 

 that will accomplish what is still to be done. 



Most of the species considered were first placed on record for 

 Connecticut by Norton, de Saussure, Bassett, Cresson, and Pat- 

 ton, all pioneers of entomology in America. Since these men 

 gave their attention to Connecticut Hymenoptera, Wheeler, Ash- 

 mead, Brues, and others have added to our knowledge. 



This introduction would be incomplete if no reference were 

 made to certain of these investigators who have made Connecti- 

 cut famous in the annals of their respective departments. Mr. H. 

 F. Bassett specialized on the four-winged gall-flies as a recreation 

 after his work as librarian in Waterbury, and made his town, as 

 well as other localities in the state, the type localities of numerous 

 species. Mr. Edward Norton, a dairyman and cattle-raiser of
