of the tuft. The comb is very similar in the different species and is 

 of comparatively little service in separating the larvae, 



Culex pipiens Linn. Genitalia, male. Basal clasp segment 

 stout broadly roimded to an oblique apex. Terminal clasp seg- 

 ment large at its base, strongly curved and tapering to a blunt point 

 bearing a stout apical spine. Claspette a subapical group of three 

 stout spines, a smaller group of several stout spines and a well 

 developed spatulate organ. Harpes divided, the major limb stout 

 with a large apical group of stout, strong spines, the minor limb 

 weak, about one fourth the length of the major, falcate with a bltint 

 apex. Harpagones long, slender, strongly curved near the apical 

 third. Unci approximate, slender with posterior extremity broadly 

 excavated, one lobe broadly rounded, the other acute. Setaceous 

 lobes moderately well developed, each with about i6 long, moder- 

 ately stout setae. 



Culex fatigans Wied. Genitalia, male. Basal clasp segment 

 stout, broadly rounded to an obliquely trimcate apex. Terminal 

 clasp segment stout, strongly curved and tapering to a rather blunt 

 apex bearing a rather stout apical spine. Claspette a subapical 

 group composed of two large and a smaller spine and another group 

 with one large and two smaller spines arising at the base of the 

 spatulate organ. Harpes short, stout, crowned with a thick group 

 of stout, chitinous spines. Harpagones stout, strongly curved 

 near the apical third and with an acute tip. Unci slender, approxi- 

 mate, with a rounded apex. Setaceous lobes poorly developed, 

 each with about six slender, long setae. 



The harpes and harpagones are both probably divided as in other 

 closely related forms, but the preparation from which the descrip- 

 tion was drawn is such that these points can not be demonstrated. 



Culex restuans Theo. Genitalia, male. Basal clasp segment 

 stout, slightly curved, apex rotmded. Terminal clasp segment 

 rather slender, strongly curved, with a fine obtuse point bearing a 

 small apical spine. Claspette subapical, consisting of three stout, 

 closely set, chitinous processes slightly curved apically, a fourth 

 one with a slender recurved point and a characteristic spatulate 

 organ at the base of which are several stout setae. Harpes rather 

 stout, and crowned apically with a series of thickly set, dark brown, 

 stout, chitinous spines and at its base there is a rather conspicuous 

 curved, chitinous process about one half its length. Harpagones 

 bifurcate, the dorsal limb curving mesally to a blimt point. The 

 ventral limb stout, curving dorsally to an acute tip. Unci broad, 

 convolute, tapering posteriorly to an oblique point. Setaceous 

 lobes median, nearly approximate, broadly roimded, bearing a few 

 rather slender setae. 



Culex territans Walk. Genitalia, male. Basal clasp segment 

 stout, curved, obliquely tnmcate. Terminal clasp segment rather 

 slender, tapering, with a rather long, slender, articulate terminal 

 spine. Claspette subapical, consisting of a pair of stout, slightly 

 curved, chitinous processes, each with an apical filament and a
