Concerning Culex perturbans at Dublin, New 



Hampshire. 



By JOHN B. SMITH. 



In the Proceedings of the Entomological Society of Wash- 

 ington, Vol. XI, pp. 145-149. Dr. Harrison G. Dyar writes in- 

 terestingly concerning the mosquitoes at Dublin, New Hamp- 

 shire, and particularly on the occurrence of Culex (Mansonia} 

 perturbans. The article is not only interesting from what it 

 contains, though there is nothing new concerning perturbans; 

 but much more interesting because of its omissions, some of 

 which I feel moved to supply to the end that the remainder of 

 the entomological fraternity may enjoy it as much as I did. 

 Dr. Dyar records the failure of the combined efforts of 

 Messrs. Busck, Caudell, Howe, Stowell and himself to locate 

 the breeding places of perturbans at Dublin in 1908 and prior 

 to August, 1909. It may be added to this, that Mr. Howe came 

 to New Jersey in 1908, received all the information we could 

 give him and went into the field with Mr. Grossbeck, who 

 showed him exactly where and how to find the larv;r. 



Mr. Howe evidently failed to profit by the instruction suf- 

 ficiently to enable him to locate the insects at Dublin, and Dr. 

 Stowell himself came to New Brunswick in October, 1908. He 

 also received full information and was taken into the field
