long as broad, slightly swollen at the basal third and tapering 

 gradually to the tip. Pecten consisting of two rows of closely set, 

 stout, dentate spines, 20 to 24 in each, with a compound hair just 

 beyond the tip of each and at about the middle of the air tube, each 

 tooth usually with one large and two or three smaller denticulations, 

 basal portion about one half the length of the longer terminal spine. 

 Chitinous ring of ninth segment about two thirds as long as broad, 

 inclosing the entire segment, barred area short. Dorsally there 

 is a long, simple caudal seta. 



This larva presents a striking resemblance to that of the typical 

 C. aurifer larvae from New Jersey. A close examination, how- 

 ever, shows that marked differences are presented by the antennae, 

 the tuft being at the basal third in this form instead of beyond the 

 middle, as in the true aurifer. There are more teeth in the labial 

 plate and an examination of the comb scales reveals a considerable 

 difference between the lateral serrations at the base which, in this 

 form, have the two subapical teeth on either side of the central spine 

 considerably stouter than the preceding ones, whereas in the true 

 aurifer there is no such marked difference. The teeth of the pecten 

 are more closely set and in aurifer the base of each pecten tooth is a 

 little stouter and usually possesses more serrations. The chitinous 

 ring of the ninth segment incloses the segment in this form and does 

 not in aurifer, 



Culex fitchii Felt & Young 



This medium sized species is a very characteristic form and well 

 colored examples may be easily recognized by examining the 

 mesonotum which is ornamented with rich brown submedian vittae 

 bordered laterally by a broad area clothed with loose, curved, 

 silvery scales. It flies from about the middle to the latter part of 

 May, and its larvae occur in association with a number of early 

 spring forms. It, like the adult, is very characteristic and may be 

 recognized by its long, uniformly tapering air tube with the continu- 

 ous, closely placed row of jet-black pecten at its base. This larva 

 appears to be confined very largely to open grassy pools such as are 

 found along roadsides or in meadows, where it may be taken in 

 association with the larvae of C. subcantans, C. abfitchii, 

 C. t r i c h u r u s, C. i m p i g e r, A e d e s f u s c u s, 

 Corethra karnerensis and C. c i n c t i p e s. 



This species is later in appearance than such early spring forms as 

 C. cantans, C. cinereoborealis and C. abfitchii, 

 all of which fly before adults of this species begin to appear. C u 1 i - 

 cada impiger and Aedes fuscus are fully as early, 

 though their breeding period is more prolonged and the two latter
