204. THE MOSQUITOES OF NEW JERSEY 



little on each side of fork with media three, and again at margin ; media 

 three, black at both ends ; cubitus one, black, beginning short distance 

 from base and extending to fork with cubitus two, white for short dis- 

 tance, then black to cross-vein, and again at margin; cubitus two, 

 slightly black at tip and anal vein black at apical fourth. Black at 

 forks at radius two and radius three, and at media one, two, three so 

 close together they appear as distinct spots ; others not so obvious. 



Abdomen apically banded with yellowish white, bands prolonged for- 

 ward in middle and intersected irregularly with dark brown of basal 

 part ; in some specimens this intersection carried further, so that brown 

 predominates, giving abdomen mottled appearance. Sometimes brown 

 carried across base of segment almost dividing band in two. Whitish 

 beneath in most central part which merges into brown of sides. 



We know nothing of the habits of this mosquito nor whether it bites. 

 The adult has never been taken by any of the collectors, and from the 

 practical standpoint it need not be considered at all, in New Jersey. 



DESCRIPTION OF THE LARVA 



Yellowish brown when full grown. Measures from 7—8 mm. (.28— .32 

 inch) in length including anal siphon, rather short and stout. Head al- 

 most as large as thorax, one and one-half times as broad as long, exca- 

 vated immediately before antenna, square in front ; pale yellow, without 

 markings of any kind ; from center of vertex arise four hairs, each from 

 separate pit ; tuft of four or five hairs at base of each antenna. Antenna 

 large and white, partly covered with small stout spines, almost as long 

 as head is broad, thickest centrally, with out and in curve, terminating 

 almost to point. Tuft well below middle, consists of about dozen hairs. 

 Two long spines, midway between tuft and apex, represent two of four 

 spines which usually crown apex ; apex with two short articulated spines 

 and small joint. Eyes occupy sides of head, and are crescent-shaped, 

 with small detached portion at posterior margins. Hairs composing 

 rotary mouth brushes simple. Mentum triangular, broader than long, 

 very constant in form, with eight teeth on each side of apex. 



Mandible of usual form, but peculiar by possessing only single dorsal 

 spine. Maxillary palpus scantily clothed with hair, apical tuft rather 

 large and of long hair. Basal joint small with number of very small 

 spines at apex. 



Thorax wider than long, with rounded margins and moderately long 

 hair tufts. When larva about to change into pupal condition, thorax 

 becomes shriveled, dorsal surface depressed, and large prominences 

 form on anterior margin, giving impression of entirely different species.
