Culex azymus sp. nov. 



9 . Palpi, proboscis and antennae black ; head white behind, with a 

 patch of black, forked scales in the middle, black on the sides below, setae 

 black. Thorax black, golden-brown scaled, uniform, without spots, setae 

 black ; pleurae whitish, with a black band above bases of legs and another 

 below wings. Abdomen black, with narrow whitish basal segmental 

 bands, widening laterally, venter grayish white. Legs black, the femora 

 pale below, tibiae and the first two tarsal joints appearing whitish on lower 

 side in certain lights, unbanded. 



Allied to Culex pleuristrialus Theobald, but lacking the thoracic spotting 

 and any trace of the white tarsal bands. 



The larva is allied to pleuristrmlus (Journ. N. Y. Ent. Soc., xiv, 205, 209, 

 1906), but the pecten of the air tube has two detached teeth, which exceed 

 the two basal hair tufts. 



One specimen, bred from larvae in Bromelia water at Arima, Trinidad 

 by Mr. F. W. Urich. 



Type. Cat. No. 10,020, U. S. Nat. Mus. 



Culex basilicus sp. nov. 



9 . Proboscis black with a broad, dull white ring ; antennae and palpi 

 black ; head with light golden yellow scales behind. Thorax black with 

 brown-black scales centrally; along the sides of disk a band of light yellow 

 scales with a narrow square central projection into the disk ; a square 

 patch of same color behind, and on scutellum; pleurae whitish, marked, 

 with black above, centrally and on the bases of the legs. Abdomen black 

 with central basal white spots on the first four segments, pale terminal 

 hairs on all the segments ; venter w r ith short, broad white basal segmen- 

 tary bands. Legs black, femora pale beneath, tips of femora and tibiae white, 

 tips and bases of the tarsal joints very narrowly white. Wings with nar 

 row scales. 



The larva falls in the table with janitor and lactator (Journ. N. Y. Ent. 

 Soc., xiv, 205, 1906), but differs in having the ring of the anal segment 

 broad ; pecten of eight spines reaching to the middle of the air tube ; one 

 tuft within the pecten, three beyond it, not in line, two tufts on the dorsal 

 aspect of the tube, all the tufts 2-haired only, thick and coarse. 



Five specimens, bred by Mr. Urich from larvae in a tub near the kitchen 

 at Arima, Trinidad. 



Type. Cat. No. 10,021, U. S. Nat. Mus. 



Culex consolator sp. nov. 



The larva is very close to Culex rejector Dyar & Knab, unbred (Journ. 

 N. Y. Ent. Soc., xiv, 221, 1906), found in Bromelia water at Cordoba, Mex 

 ico. It differs in having the hair tufts on the tube long, the anal segment 

 with a lateral rosette of spines. A single male was bred by Mr. Urich 

 from a larva in Bromelia water at Arima, Trinidad. 



cT. Head black, with narrow, curved whitish-gray scales behind and 

 black setae. Proboscis black, palpi black, very hairy, with white rings at
