DESCRIPTION OF A NEW CULEX. 



BY JOHN A. GROSSr. ECK, PATERSON, N. J. 



Culex siphonalis, sp. nov. — 9 . Head brown, occiput covered with 

 pale' yellow scales ; antennpe brown, basal joint and two following ones 

 testaceous ; proboscis pale brown, with dark brown scales scattered over 

 the surface, covering the apical fourth ; palpi dark brown, with minute 

 terminal joint oval in form, pointed at the apex and slightly spiny. 

 Mesonotum covered with pale yellow and brown scales at the sides and 

 with a median vitta wholly of brown scales, the pale yellow scales some- 

 times forming a narrow border to this vitta ; scutellum brown, with 

 yellowish-brown bristles on the posterior margin ; metanotum evenly 

 brown ; pleura brown, clothed with patches of dirty white scales ; halteres 

 yellowish-white, black at the apex. Abdomen blackish-brown, with pale 

 yellowish basal bands and extremely narrow apical ones on the posterior 

 three segments, irregularly merging into the brown, becoming diffused at 

 the sides until beneath are mixed brown and white scales, the latter 

 predominating. Legs with coxte yellowish-white ; femora with mixed 

 black and white scales, wholly yellowish beneath and with a white dot at 

 the knee ; tibiae blackish-brown, sprinkled with whitish scales ; tarsi black, 

 except the first tarsal joint, this like the tibiae, narrowly white banded at 

 the base in the anterior and mid feet, save the fifth joint in the anterior 

 one, posterior feet broadly white banded basally ; claws slender, uniser- 

 rated ; wings hyaline, petiole of first submarginal cell about half as long 

 as this cell. Length, 5 mm. 



(5 . — Palpi brownish, with a pale band in the centre of the basal 

 joint and at the base of the two terminal joints. Claws all uniserrated. 

 The bands of the abdomen very broad, mixed with brown scales and 

 tending to cover the entire surface in the apical segments. Petiole of first 

 submarginal cell almost as long as this cell. Length, 6 mm. Otherwise 

 as in the female. 



This species closely resembles Culex canians, but differs in the 

 median thoracic stripe, the much more slender claws, its darker colour 

 and smaller size. The larvae are obviously different from those of 

 cantans, possessing a very long anal siphon, which has suggested the 

 name. 



Described from two females and five males bred from larvae collected 

 at Livingston Park, New Jersey.
