The adults are medium sized, the legs and beak black, the abdomen 

 with white lateral patches basally on the distal segments, and the 

 thorax with the lateral areas covered with long, silvery, grayish 

 scales. The species is too rare to be of economic importance. 



Aedes abserratus Felt & Young. One specimen doubtfully 

 referred to this species was taken at Lake Bluff July 1 5th, presum- 

 ably in a swamp inhabited by Aedes aurifer and A. 

 abfitchii. 



House mosquito (Culex pipiens Linn.). Larvae and pupae 

 of this common species were found during June, July and August, 

 being taken mostly in dirty or stagnant water, and particularly in 

 water barrels, in one instance being found in a tree hole which was 

 also inhabited by the tree hole mosquito, Aedes triseriatus 

 Say. 



The house mosquito breeds so generally in artificial collections 

 of stagnant water near human dwellings that it should be com- 

 paratively easy to prevent its occurrence in great numbers. 



White-dotted mosquito (Culex restuans Walk.). This 

 common species is closely related to the house mosquito and, like it, 

 breeds in artificial collections of water. Adults and larvae were 

 taken in July and August, though at no time in such abundance 

 as to warrant ranking this form as a pestiferous one. 



Little Black mosquito (Culex territans Walk.). This is 

 a small, black species which may be easily recognized by the white 

 bands at the apex of the abdominal segments. The larvae are 

 found almost everywhere in running or stagnant waters, though 

 usually not abundant in that which is foul. Larvae and pupae 

 were taken during June and July, adults being found the last of the 

 latter month. Breeding appears to occur as in the related house mos- 

 quito and whitedotted mosquito, throughout the warmer part of 

 the year. 



The collections of the past season failed to demonstrate an unusual 

 abundance of the adults, though larvae were frequently taken. 

 Statements regarding conditions of earlier years, however, indicate 

 that this species is frequently sufficiently abundant to constitute 

 a real nuisance. The dark color of the adiilts in connection with 

 their ability to make their way through ordinary mosquito netting, 

 leaves little doubt that this species is "occasionally exceedingly 

 numerous and troublesome. 



Dyar's mosquito (Culex dyari Coq.). This rare species, 

 first taken at Center Harbor, N. H., was met with in the larval 

 form June 8th near Second creek, only one specimen being taken. 

 It is apparently an early spring form which rarely becomes abundant 

 and is therefore of very little economic importance.
