THE CRANE-FLIES (TIPULIDAE) OF NEW ENGLAND: FIRST 

 SUPPLEMENTARY LIST. 



BY CHARLES P. ALEXANDER. 



The appearance in press of Mr. C. W. Johnson^s monumental 

 work on the Diptera of New England (Occas. Papers Boston Soc. 

 Nat. Hist., vol. 7, no. 15, p. 1-326, 1925) has proved a great in- 

 centive to further detailed work on this fauna. In this paper Mr. 

 Johnson lists 1 Tanyderid, 3 Ptychopterids and 9 Anisopodids, in 

 addition to the main list of 264 species of Tipulids. During the 

 season of 1925, the writer collected intensively in western Massa- 

 chusetts, in Area 23 (the Berkshire Area) and Area 24 (the Con- 

 necticut River Valley Area). As a result of this detailed collecting 

 with certain definite groups in view, 13 species of Tipulidae may 

 now be added to the basic list. In the present small paper the 

 writer wishes to record these additions, discuss briefly the collec- 

 tions made at Lake May in the Berkshires, and describe two 

 novelties that are included in the list of additions.

 Hanover, in southern Indiana.
