EXPERIMENT STATION EEPORT. 681 



the thorax is covered with pale brown scales and has a narrow median 

 furrow, obsolete on posterior portion, bounded on each side by scales 

 of a slightly darker color: a lateral line of pale yellow scales begin- 

 ning near the posterior margin and extending to the middle of the 

 lateral margin, also encloses these darked scales. The pleura are 

 yellowish-brown, with patches of whitish scales. The legs are cream 

 colored, the anterior part of all femora and also anterior part of 

 tibia of fore-leg brownish; the apical two or three joints of fore and 

 mid tarsi are also brownish. The claws are equal in size on all feet, 

 each with a single tooth at the middle. The abdomen is unhanded, 

 creamy, with metallic, silvery-gray lustre in living specimens, but 

 darker with grayish shadings when pinned; the genitalia are dark 

 brown. 



Habits. 



This species was taken only in the pupal stage with C. canadensis 

 larvae and pupae and Corethra cinctipes, collected by Mr. Brehme in 

 the Orange mountains, May 19th and May 22d. From the first lot a 

 female emerged May 25th, and out of the second another female 

 issued on the 26th. All remaining larvae were put into alcohol at 

 once, and though numbering hundreds, none could be differentiated 

 from C. canadensis. Another collection was made May 27th, and its 

 entire mosquito contents taken ; but all larvae proved to be canadensis, 

 and none other than that species hatched from the pupae. It is 

 probably one of the early spring forms with but a single brood, since 

 it was not taken in any of the collections later in the season. 



Culex triseriatus Coq. (The Tree-Hole Mosquito). — This mosquito 

 was taken continuously throughout the season wherever tree-holes con- 

 taining water were found. The earliest record of larvae thus far is 

 April 18th, when examples in the first and second stages of develop- 

 ment were found on Garret mountain, Paterson. 



C'ldex serratus Theob, (The Silver-Striped Mosquito).— This 

 species was not taken in any stage. 



Culex punctor Kirby. (The Unbanded-Legged Woods Mosquito). 

 — This is a rather large mosquito with brown, unhanded legs and beak. 

 The thorax is evenly clothed with golden brown hair and the abdomen 

 is broadly banded with white at the base of the segments. In calling 

 this species punctor we are following Dr. Dyar, who says that 

 absermtus F. & Y. is a synonym. Dr. Felt does not admit this, and 

 the description given by Theobald does not cover this species. At all 

 events the form here called punctor is the form described as ahserratus, 

 — so Dr. Felt savs.
