332 A Monograph of Culicidae. 



Habitat. — Livingston Park, New Jersey, U.S.A. (Van 

 Dursen). 



Time of appearance. — May." 



Observations. — The description is taken from Smith (p. 244), 

 ^ts this species has not been received. It is said to closely 

 resemble Culicada cantans, but is smaller, darker in colour, and 

 with a brown line in the centre of the mesothorax, and the 

 abdominal bands are greyer and more diffuse. It seems to me 

 to approach more closely C. abfitchii, Felt. It is a wood mosquito 

 and is an early species. The adults have not been caught, all 

 have been reared. The larva differs from C. cantans in antennal 

 structure, and in the form and armature of the siphon. It is 9 

 to 1 1 mm. long, light grey to yellowish brown with somewhat 

 darker thorax j the antennae are curved, with a few short thorn- 

 like spines and three or four regular rows of minute spines 

 running from the base towards the apex ; lateral tuft well below 

 the middle and consists of three or four long hairs ; three 

 irregular lengthed apical spines and an articulated process. 

 There are 24-30 scales on comb of eighth segment, the apex long 

 with three thick spines, and fine ones along the sides ; spines of 

 pecten of siphon 15-22 in each row of varied form. The larvae 

 occurred in swampy woodland with C. canadensis and a Corethra. 



They occur only in deep pools, and hide amongst leaves at 

 the bottom of them, and amongst which they feed. 



Pupation began on May 7th \ the pupal period lasting from 

 four to five days. The winter is probably passed in the egg 

 stage (Smith, p. 248). 



It is now said that this is only Felt's C. abfitchii. It certainly 

 reads very much like that species.
