longer than broad, tapered on its outer half, with double row of pecten, 

 the teeth two-spined, followed by a small tuft ; dark brown. Lateral 

 comb of eighth segment small, the spines irregularly shaped and 

 digitately spined (PI. II, Fig. i, B) in an irregular double row. 

 Anal segment short, ringed by the plate, tuft and brush normal, the 

 brush without hairs before the barred area from which it arises. Anal 

 processes four, moderate. 



Culex nigritulus Zetterstedt. 



Received only from the salt marshes as noted above. 



Larva. — (PI. II, Fig. 3.) Head rather large, broad through the 

 eyes, narrow before, pale, brown-blotched on the vertex ; eyes black, 

 transverse ; antennae large, long, the outer third narrower, the tuft at 

 the point of narrowing ; black at base and tip, broadly white banded 

 centrally. Body normal, hairs moderate, diminishing posteriorly. 

 Air tube long and slender, as long or longer than in territans, but 

 straight, regularly tapered, not concave; brown, the tip darker; 

 double row of pecten of 3-spined teeth and scattered hairs beyond. 

 Comb of eighth segment a patch of about 40 small spines in three 

 rows. Anal segment about as long as wide, ringed by the plate, tuft 

 and brush normal, the latter confined to the barred area. Anal pro- 

 cesses four, moderate. 



There seems a possibility of question whether this is the true 

 jiigritulus of Europe. Theobald's statement that he had taken the 

 adults about old water butts scarcely suggests the habits of our salt 

 marsh species. 



Culex consobrinus Desvoidy. 



Messrs. J. W. Dupree and H. A. Morgan have very kindly com- 

 municated to me specimens of this species, identified by them in 

 Baton Rouge, La. The mature larva sent seems inseparable from that 

 which I at first supposed to be C. incidens Thomson (Proc. Ent. Soc. 

 Wash., V, 160, 1903). The antennal tuft is at the middle, the air tube 

 about three times as long as wide, slightly inflated and with the peculiar 

 prolongation of the pecten teeth into sette, while the other characters 

 agree. Several young larvje also were sent in the bottle. They differ 

 greatly. The antennal tuft is well at the outer third of the long, 

 completely infuscated joint ; the tube is nearly four times as long as 

 wide, tapered outwardly and with a small row of spinous teeth at base 

 followed by several hair tufts ; the anal segment has a dorsal plate, the
