Obiginai, Description of Culex fitchii: 



A long-tubed larva with a comb consisting of about eighteen triangular, stout, 

 spined scales arranged in two or more rows, some ol the scales having a very stout, 

 terminal spine with smaller ones along each side, while others have the tips some- 

 what rounded and the spines more nearly of a size, was taken in a woodland pool at 

 Karner, on May 10, adults emerging on the sixteenth. The air tube Is fully five 

 times as long as its greatest diameter, tapering somewhat regularly and with a 

 slight bend and contraction near the middle. There are two rows of pecten, each 

 consisting of about twenty-two closely-set teeth bearing at their bases usually two 

 larger and three or four fine serrations. This species, Culex fitchii n. sp.. Is close to 

 Oulex squamiger Coq., and may be separated therefrom by the scales of the pleura 

 being white and the posterior cross vein its own length from the one above. The 

 basal segments of the antennae are clothed Interiorly with broad white scales; 

 proboscis dark-brown, long; palpi dark brown, segments narrowly ringed at the 

 base with white; occiput clothed with brown scales, with a row of silvery ones just 

 above the eyes and along the median line. Thorax with a broad, brown, central 

 stripe bordered with a rather well-defined silvery, slightly broader, lateral stripe con- 

 taining a few brown blotches. Pleura rather thickly clothed with patches of silvery 

 white scales. 



Descbiption of Femam;, Maij:, and Labva of Aedes fitchii: 



Female. — Proboscis moderately long and slender, subcylindrieal, flattened, 

 the labellae eonically tapered ; vestiture brownish black with a few whitish scales 

 intermixed ; setae minute, curved, black, those on labellse more prominently out- 

 standing. Palpi rather stout, short, less than one-fourth as long as the pro- 

 boscis, clothed with black scales, tips and bases of joints with yellowish-white 

 scales ; set^e moderate, black. Antennae with the basal joints somewhat shorter 

 than the distal ones, second joint larger and thicker and pale at base, the 

 remaining joints rugose, blackish, pilose; tori subspherical, with a cup-shaped 

 apical excavation, luteous, brown and with a patch of small white scales on inner 

 side; hairs of whorls sparse, black. Clypeus shortly conical, prominent, nude. 

 Eyes black. Occiput blackish, very broadly clothed with narrow, curved, yel- 

 lowish white scales and laterally a diffused patch of brown ones, many slender 

 erect forked black scales on nape ; cheeks clothed with flat white scales, a quad- 

 rate patch of black ones above at eye-margin ; bristles bordering the eyes black, 

 a tuft of pale ones projecting forward at the vertex. 



Prothoracic lobes elliptical, remote dorsally, blackish, clothed with pale yellow 

 scales and black bristles. Mesonotum dark brown, clothed with narrow curved 

 scales, a broad median stripe of golden brown ones, anterior margin narrowly 

 and the whole of the sides of the disk as well as the antescutellar area with pale 

 sordid-yellowish ones, extreme lateral margins golden brown scaled; sides of 

 disk with more or less of brown scales intermixed; bristles moderate, black. 

 Scutellum trilobate, luteous, each lobe with a group of black bristles and 

 clothed with narrow, curved, pale yellowish scales. Postnotum elliptical, short, 

 luteous, pruinose, nude. Pleurae and coxae pale brown, clothed with elliptical 

 white scales and rows of short pale bristles ; prothoracic epimera with golden 

 brown scales. 



Abdomen subcylindrical, flattened, posterior segments tapering ; dorsal vesti- 

 ture of black scales with a few pale ones intermixed, each segment with a broad,
