June, 1929] MOSQUITOES OF NEW HAMPSHIRE 17 



The author's records are from the southeastern part of the state, the 

 other distribution records being taken mostly from published reports. 

 The late H. G. Dyar, who was our foremost national authority on mos- 

 quitoes, has collected in the state, principally at Center Harbor, and 

 many records are taken from his publications. August Busck also col- 

 lected in the state. C. W. Johnson, of the Boston Society of Natural 

 History, has done much collecting in New Hampshire and has published 

 a "List of the Diptera or Two-winged Flies'' of New England which 

 contains many records for New Hampsphire mosquitoes. We are also in- 

 debted to Mr. Johnson for permission to examine the mosquitoes in the col- 

 lection of the Society. Under each species we have given the localities 

 where it has been found, the date collected and the name of the col- 

 lector. In the case of the three men named above, we have used their 

 initials. Where no collector is given, the record is that of the author. 

 All records are for adult mosquitoes unless otherwise stated.
