BRIEF NOTES ON MOSQUITO LARVAE. 



By Harrison G. Dvar, A.M., Ph.D., 

 Washington, D. C. 



Correction of the account of Culex consobrinus Desy. — I 

 described this larva from specimens sent by Messrs. Dupree and Mor- 

 gan (Journ. N. Y. Ent. Soc, xi, 24, 1903), and expressed some doubt 

 both there and at another time (Proc. Ent. Soc. Wash., vi, 39, note, 

 1904), whether the young larvae were correctly associated. We have 

 lately received from Dr. Dupree a full set of specimens of all stages, 

 and it shows that the first ones were wrongly associated. There is no 

 such remarkable change as those specimens indicated. 



The eggs are laid in curved, boat-shaped masses, as in pipiens. 

 The first-stage larvae have the antennae longer than the mouth brushes 

 with a single hair at the middle ; tube thick, about two and a half 

 times as long as wide, with the outer half weakly infuscated, the pecten 

 of four branched teeth with the usual tuft, composed of one hair, at 

 about the middle of the pecten, very near the base of the tube. Anal 

 segment with a dorsal plate and dorsal tuft of four hairs and one 

 smaller side hair. Lateral comb of the eighth segment of five long, 

 sharp spines. In stage ii the antennae are as long as the mouth 

 brushes only, with a tuft at the middle ; the tuft of the air tube con- 

 sists of two hairs, situated at the base of the posterior incision of the 

 chitin, the pecten of seven branched teeth and two remote, longer, 

 unbranched ones. The comb of the eighth segment is three rows
