MOSQUITOS OR CULICIDAE OF NEW YORK STATE 303- 



Culex annulatus Schrank. 



This mosquito may be easily separated from others having 

 banded tarsi, by the broad band on the posterior tarsi. 



Distribution. Dr Howard has recorded this insect from New 

 Bedford Mass., Lincoln Neb., Santa F6 N, M., Stanford Cal., and 

 Logan, British Columbia. It has also been recognized by Mr 

 Ludlow at Fort Baker Cal. It appears to be widely distributed 

 in this country, specially a® it has also been reported from 

 Mexico'. Theobiald statesi that this species is common through- 

 out Europe, from Scandinavia to Italy, and also occurs in India. 



Giles states that this large gnat is believed by Ficalbi, to feed 



only on the juices of plants, and he thinks that it does not attack 



man or animals.

This comparatively large, rather handsome mosquito may be 

 easily recognized by the last segment and each extremity of the 

 other segments of the tarsi on the posterior legs being white. The 

 petiole on the first submarginal cell is about two thirds its length, 

 a character readily separating this species from C . a t r o p a 1 - 

 pus, which according to Coquillett has the petiole less than 

 one half the length of the cell. The claws are all unidentate in 

 specimens received from Theobald. This mosquito is at no time 

 very abundant. 



Description. The eggs according to Dr Dyar are laid singly, not 

 adherent, fusiform, with ends rounded, black. The full grown 

 larva has a pale brown head, with antennae brownish throughout, 

 though darker on the outer third, a slight tuft a little before the 

 middle. The air tube is conical, tapered, about two and one half 

 times as long as wide, with two rows of pecten at the base. The 

 comb consists of a triangular patch of small scales over three rows 

 deep. Dr J. B. Smith states that the larva of this species is asso- 

 ciated with that of C . c a n t a n s , which it resembles so closely 

 that the two are not easily separated. We have bred this 

 species, from woodlaind pools where it was assoeiated with C.
