the dorsum, at the front angles of the posterior segments. These 

 lateral marks often continue narrowly across the abdomen, espec- 

 ially in the males. 



Habits of the Adult. 



This is another woodland mosquito, and one which has not, up 

 to the present time, been found in towns or even on porches of 

 buildings surrounded by trees. It has never been found indoors, 

 anywhere. The species breeds in some numbers on the ridge back 

 of South Orange, but none of the specimens taken in that place 

 were referable to this species. Outdoor captures were made July 

 2d, at Trenton, by Mr. Grossbeck; July 4th and 5th, at Chester, 

 by Mr. Dickerson; July 13th, at Summit; July 17th and i8th, at 

 Deckertown; July 21st and 22d, at Lake Hopatcong, all by Mr. 

 Grossbeck; August 25th, at Jamesburg, by Mr. Marsh, and Sep- 

 tember 3d, in the Great Piece Meadow, by Mr. Brehme. All 

 these localities are from the more northern section of the State 

 and none are south of the red shale except the Jamesburg locality. 

 All the collectors report that this mosquito is fierce in its at- 

 tack, but not one was really bitten. The insects seemed to 

 tackle low — that is, they rarely came above the knees, Mr. 

 Grossbeck being especially emphatic on this point. The result 

 was that these parts, being protected by the clothing, did not 

 suffer, while the insect yet gave an exhibition of its good in- 

 tentions in the matter. 



Description of the L,arva. 



The larva (plate 90, fig i) is a stout, robust wriggler, 

 measuring 7-7.5 mm., ^.28-. 30 of an inch, to the tip of the 

 ninth abdominal segment. The body is dark gray, with the 

 exception of the head, siphon and anal segment. The head is 

 rather small, one-third wider than long and evenly rounded in 

 front ; in color yellowish with large dark brown blotches which 

 give the predominating shade. From the anterior part of the 

 vertex arise four single hairs, each from a separate pit; the pits 

 so arranged as to form a square, narrower in front ; a small tuft 

 of four or five hairs at the base of each antenna. The antenna 

 (fig. 90, 2) is short, evenly tapered apically. yellow in color, 

 becoming very dark brown toward the apex ; the surface set 

 with rather large spines with very small ones intermingled. 

 The tuft, consisting of eight or ten hairs, is situated on the 

 shaft slightly below the middle and the apex has one long spine,
