closely set distal group of about three shorter, stout setae. Harpes 

 long, rather slender, curved apically and adorned with a series of 

 long, fingerlike teeth. Harpagones fused ^to form a somewhat 

 keel-like organ with the lateral portion prolonged distally, broadly 

 roimded and tipped with a series of short, stout spines. Unci 

 approximate, slender, excavated posteriorly, with acute dorsal and 

 ventral prolongations. Setaceous lobes small, abruptly rounded, 

 bearing a number of rather fine setae. 



Culex tarsalis Coq. Genitalia, male. Basal segment of clasp 

 stout, curved, nearly obliquely truncate at apex. Claspette sub- 

 apical, composed of three stout, closely set, tapering spines with 

 recurved tips and a well defined, spatulate organ, the latter with 

 two curved bristles arising from near its base. Apical segment 

 rather stout, curved, tapering, with a small terminal articulate 

 spine. A rather inconspicuous lobed process bearing short, stout, 

 chitinous teeth, appears to be the basal portion of this organ. 

 Harpes stout, broad, bearing apically a thick mass of stout, nearly 

 black, chitinous spines. Basal portion with a strongly curved, 

 tapering process. Harpagones short, stout, with a prominent 

 ventral, somewhat folded lobe, its apex rounding to a somewhat 

 acute tip, the main portion bearing at its apex two long, stout, 

 dark brown, chitinous teeth and a shorter, intermediate spur. 

 Unci approximate, slender, tapering to acute points. Setaceous 

 lobes slightly developed, rounded, bearing a series of rather long, 

 curved setae, 



Culex cylindricus Theo. Genitalia male. Basal clasp segment 

 rather stout, rounding gradually to a rather acute apex. Terminal 

 clasp segment stout, tapering gradually to a blunt point bearing a 

 pair of rather stout apical spines. Claspette represented by a 

 subapical group composed of two stout spines with recurved points, 

 a slightly longer, more slender one with a smaller group of three 

 smaller, slender spines with recurved points and a well developed 

 spatulate organ. Harpes stout with a thick, tran verse apical 

 group of stout, chitinous spines, the inner blunt, the outer acute. 

 Harpagones stout, recurved, acute. Unci and setaceous lobes 

 indeterminate in the preparation. 



Culex annulirostris Skuse. Genitalia, male. Basal clasp seg- 

 ment stout, gently rounded to a rather acute apex. Terminal 

 clasp segment much enlarged at base, tapering rapidly near the 

 midcls to a rather acute tip bearing a pair of stout apical spines. 

 Claspette a subapical group composed of three large and three 

 smaller spines and an acute tipped spatulate organ. Harpes 

 divided, the main limb stout with its apex crowned with a thick 

 group of itout spines. Minor limb smaller, strongly curved, fal- 

 cate with an acute apex. Harpagones slender, divided into a 

 series of about four more or less curved, acute, stout, chitinous 

 processes. Unci slender, approximate, prolonged in a bifurcate 

 Y-shaped apex, the outer limb stout, acute, the inner linear. Unci 

 indeterminate in the preparation.
