394 A Monograph of Culicidae. 



three preceding segments, pale testaceous, black at the apex and 

 with a black basal ring and black spot, a row of small bristles on 

 its basal half and a line of fine hair-tufts on the apical portion, 

 these are four in number ; at its base three tufts of bristles on 

 each side and a group of spines ; anal segment with a few long 

 black dorsal bristles and pale ventral fan ; gill plates long and 

 narrow. 



Length. — 8'b to 9 mm. 



This species was bred by Dr. Grabham from larvae with long 

 siphons. Five males and one female were sent me, but some of 

 the (J 's are smaller than the type, one only 4 mm. long. 



Culex tarsalis. Coquillett. 1896. 

 Culex. n. sp. Williston. 1893. 

 Culex w'dlistonu Giles. 1900. 

 Culex affinis. Adams. 1903. 



Canad. Entomo., p. 43 (1896) (tarsalis) ; North Ameri. Faun. 7, p. 253 (1893) 

 (n. sp.), Williston; Hndbk. Gnats, 1st ed., p. 281 (1900) (ivillistoni) , 

 Giles; Kansas Uni. Sc. Bull, p. 25 (1903) (affinis), Adams. 



The above is the synonomy given by Coquillett of this species 

 in the " Canadian Entomologist" for 1904 (p. 261). 



With regard to affinis of Adams, this seems correct, and 

 Coquillett's description of tarsalis, which is the same as "Williston's 

 n. sp., antedates Giles' Culex willistoni. 



I have not seen Coquillett's type of tarsalis, if it answers the 

 description of kelloggii then, I suppose, the latter must sink 

 as a synonym ; if it is the same, Coquillett missed out the 

 most marked character, namely, the very prominently spotted 

 legs, and no one could ever identify the species from his description. 

 If the legs are spotted in tarsalis then it is doubtful to place 

 Adams' affinis as a synonym, in which no mention is made of the 

 spotted legs. 



These are probably two species, and unless one has a full 

 description of tarsalis it is best to leave kelloggii distinct. 



This is recorded from British Columbia (Dr. Dyar) and Fort 

 Baker, California (Miss Ludlow) ; Mississippi (Glenn Herrick).
