Genus Culex. 415 



in New Hampshire and in a cold stream in the woods in British 

 Columbia. The latter pupated on May 29th. 



Dr. Dyar is of opinion that there is only an early spring brood. 



The larva has a pale brown head and stout antennae, a tuft 

 on the outer third and the part beyond smaller. Siphon four 

 times as long as broad, tapering rather abruptly beyond the 

 middle. Comb of over eighty scales in about ten rows. Professor 

 Felt figures the labial plate with eleven teeth on each side of the 

 apical one, the third and fourth from the base the largest and 

 furthest apart. He places this species in a new genus, Culicella 

 (Mos., N. Y., Bull. 79, Ent. 22, p. 391, c. (1902)). It is a 

 typical Culex in all respects. The characters he gives for this 

 genus are merely specific, and they are even variable ones, except 

 those of the <J genitalia. 



Culex corniger. Theobald (1903). 

 Mono. Culicid. III., p. 173 (1903). 



A male recently given me by Dr. Lutz shows a variation in 

 the thoracic adornment ; the pale golden scales form a mass on 

 each side in front from the inwardly projecting pale scaled area ; 

 the anterior pale areas have a brown central region. 



The palpi are acuminate, brown, with large pale apex, then 

 two narrow pale bands and a larger basal one ; the last two 

 segments and one side of the anterior part of the antepenultimate 

 with prominent hairs, those on the apex pale, some pale ones at 

 the first small pale band, rest deep brown. 



Locality. — Santos, Brazil (Dr. Lutz), taken in June. 



This species will probably have to be excluded from Culex. 



Culex quasilinealis. n. sp. 



Head with yellowish-brown scales, darker on each side. 

 Thorax pale brown with two dull yellowish median parallel 

 lines, dull yellowish scales laterally, and sending a dull yellowish 

 curved line on each side to the median parallel lines, and thus 

 enclosing two darker areas in front. Abdomen deep brown, 

 with basal white bands and pallid border-bristles. Legs deep 

 brown, unbanded. 



9 . Head brown with narrow-curved pale creamy scales and 

 pale flat lateral ones, deep brown upright forked scales behind,
