CONNECTICUT GEOL. AND NAT. HIST. SURVEY. 



[Bull. 



Farmington, very modestly made the study of the sawflies, four- 

 winged parasitic flies, and cuckoo or gold wasps his recreation, 

 and found many new species in the state. He furnished ma- 

 terial to Mr. E. T. Cresson, the Philadelphia insurance expert 

 and hymenopterist, and to Henri de Saussure, the great Swiss 

 naturalist. The contributions made to the knowledge of Con- 

 necticut insects by these men were important, and were based 

 chiefly upon material collected by Mr. Norton, who also trans- 

 lated and edited de Saussure's " Synopsis of American Wasps." 

 Professor W. M. Wheeler, Professor of Economic Entomology, 

 Harvard University, a prominent zoologist and an eminent 

 student of ants, has made some of his remarkable investigations 

 on the habits of ants at his summer home in Colebrook. Several 

 type localities in the state have resulted from his studies. 



The best collections of Connecticut Hymenoptera now in ex- 

 istence are that of the American Entomological Society at the 

 Academy of Natural Sciences, Philadelphia, which contains types 

 and paratypes of the species described from Connecticut by 

 Norton, Cresson, and Bassett; and that of the Connecticut Agri- 

 cultural Experiment Station, New Haven, where types of sev- 

 eral of the recently described species may be found. Other 

 material containing some types may be found at the United 

 States National Museum, Washington, D. C. ; the American Mu- 

 seum of Natural History, New York City ; the Peabody Museum 

 of Yale University, New Haven; the Museum of Comparative 

 Zoology, Cambridge, Mass. ; and the Museum of the Boston So- 

 ciety of Natural History.
