REPORT ON MOSQUITOES. 281 



grown larv?e were found August 9th by Air. J. H. Voorhees, and 

 on the 15th mature larvae and pupa^ were taken. September 3, 

 1903, a few more parth^ g■ro^^•n larvae were found at Livingston 

 Park by Mr. Van Duersen, and on the 9th Mr. Grossbeck found 

 a few nearly full grown larvae in a woodland pool in the Great 

 Piece Meadow, from which adults were obtained September 17th 

 and 2 1 St. The latest collections were made September 30th at 

 Livingston Park, and adults from this lot were all out before 

 the middle of October. 



From this record a continuous breeding is indicated, the num- 

 ber of existing pools determining the number of broods. Though 

 there was an abundance of rain near New Brunswick during 

 the summer, the woods were, nevertheless, unusually dry, a result 

 of the very severe, continuous winter which kept moisture out of 

 the ground and allowed the water to run off or to evaporate in 

 the spring before the surface was in an absorbent condition. The 

 result was that when rains did come they were completely ab- 

 sorbed and not enough was in the ground at any time to allow 

 standing surface pools.

Description of the Adult. 



This is a small blackish mosquito, the body measuring 2 to 3 

 mm., =.8 to .12 of an inch in length, exclusive of the beak, 

 which is about 1.5 mm. long. The occiput of the head is covered

 which sometimes mixes with the scales of the occiput. The 

 proboscis is uniformly blackish, and the palpi in the female are 

 normal, dark brown, with the terminal joint extremely small, 

 circular in outline and covered with fine short hairs. The male 

 palpi are brown, shaped like those of C. canadensis, save that
