REPORT ON MOSQUITOES. 293 



Habits of the Adult. 



This species is rather rare and has not been taken south of 

 Trenton. It occurs among the early species that develop in 

 woodland pools, two examples being bred. May 12th, from pupcC 

 taken in the Great Piece Meadow. .Vdditional specimens were 

 taken July i8th at Trenton, July 21st at Lake Hopatcong, July 

 30th at Chester, September loth and i6th at Chester. 



Both Mr. Grossbeck and Mr. Dickerson say that in its general 

 habits it does not differ from the other woodland moscjuitoes. 

 and while it bites, it is not vicious and causes no unusual pain or 

 swelling'. Of its method of passing the wdnter we know nothing 

 definite; but it is likelv that it is in the egg stage. 



This is the species that was referred to as reptaiis in Bulletin 

 No. 171 of the Experiment Station. It seems, however, that 

 there is doubt whether repfans refers to a species distinct from 

 the common iieinorosus of Europe, and if it does, to which of the 

 American forms the name should be applied. Under the cir- 

 cumstances it was deemed best to give this New Jersey form a 

 distinct name, so that there might be no doubt as to just what 

 species is intended. 



Description of tJic Larva. 



The larva and details are illustrated on figure 92. The full 

 gnjwn wriggler ( the few larvK in hand were undoubtedly full 

 grown) measures 5.5-6 mm.,=.22-.24 of an inch in length 

 excluding the anal siphon, and is pale gray to dark gray in 

 color. The head is one and one-half times as broad as long, yel- 

 lowish, with a large brown blotch on the anterior part of the 

 vertex, similar to C. sylvestris. There are four hair tufts in the 

 center of the vertex, of four or five hairs each, and a larger one 

 at the base of each antenna. The antenna (fig. 92, 5) is rather 

 short, slightly cur\'ed, pale yellow in color, faintly infuscated 

 apically ; thickest a short distance from the base and wdth the 

 surface sparsely set with stout s])ines and numerous small ones 

 arranged in longitudinal rows. The tuft is situated well below 

 the middle and consists of eight or ten hairs which do not reach 

 the apex ; the apex with one long spine, se\'cral smaller ones and 

 a small joint. The rotary mouth brushes are dense, with the 

 hairs of the central part pectinated. The mentum (fig. 92, 2) 

 is triangular in form with fifteen to seventeen small teeth on 

 each side of the apex. The mandible and maxillarv palpus (fig'.
