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

 lon^ 'rather slender, curved apically and adorned with a series of 

 loni; fingerlike teeth. Harpagones fused Lto form a somewhat 

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

 rounded and tipped with a series of short, stout spines. Lnci 

 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 

 <;tout c^a^^'ed, nearlv obHquelv truncate at apex. Claspette sub- 

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

 recm^-ed tips and a well defined, spatuiate organ, the latter with 

 two cur^'ed bristles arising from near its base. Apical segment 

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

 spine \ rather inconspicuous lobed process bearmg short, stout, 

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

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

 black chitinous spines. Basal portion with a strongly cur^'ed, 

 tapering process. Harpagones short, stout, with a promment 

 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 pomts. Setaceous 

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

 cur\'ed setae. 



Culex cylindricus Theo. Genitalia male. Basal clasp segment 

 rather ^tout rounding ^raduallv to a rather acute apex. Terminal 

 clasp segment stout, tapering graduaUy to a blunt pomt bearmg a 

 pair of rather stout apical spines. Claspette represented by a 

 subapical group composed of two stout spines with recuived pomts, 

 a sli^htlv longer, more slender one with a smaller group of three 

 «;mafier 'slender spines with recur^-ed points and a weU developed 

 spatuiate organ. Harpes stout with a thick, tranverse apical 

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

 Harpagones stout, recur%^ed, acute. Unci and setaceous lobes 

 indeterminate in the preparation. 



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

 ment stout, gentlv rounded to a rather acute apex. Temunai 

 clasp segment much enlarged at base, tapermg rapidly near the 

 midcl- to a rather acute tip bearmg a pair of stout apical spines. 

 Cla^^pette a subapical group composed of three large and three 

 smaller spines and an acute tipped spatuiate organ. Harpes 

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

 CTOup of stout spines. Minor limb smaller, strongly cur\-ed, tal- 

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

 series of about four more or less cmv^ed, acute, stout, chitinous 

 proce=;ses. Unci slender, approximate, prolonged ma bifurcate 

 Y-shaped apex, the outer limb stout, acute, the inner Imear. Lna 

 indeterminate in the preparation.
