Culex annulioris, 

 harpe, much enlarged, 

 showing the smooth, 

 basal, arcuate, chitinous 

 process (Original) 



Culex annulioris Theo. Genitalia, male. Basal clasp segment 

 moderately stout, rounding gradually to a somewhat acute apex. 

 Terminal clasp segment enlarged at base, strongly curved at apical 

 third and bearing a short, stout terminal spine. Claspette a sub- 

 apical group consisting of two very stout, chitinous spines with 

 strongly curved acute tips, a more slender one close beside them, 

 and slightly removed another small 

 group of about six spines and a spatu- 

 late organ, the tip of the latter appear- 

 ing unusually acute. Harpes nearly 

 divided, the main branch stout, strongly 

 curved and with a thick apical tuft of 

 stout, chitinous spines. Minor limb 

 strongly curved, sickle-shaped and with 

 an acute apex. Harpagones short, 

 stout, terminating in a series of strongly 

 curved, stout, chitinous spines. Unci 

 slender, probably approximate, gradu- 

 ally rounding to an acute apex. Seta- 

 ceous lobes weakly developed, each with 

 about six slender, curved setae. 



Culex tigripes Grand. Genitalia, male. Basal clasp segment 

 rather expanded at the extreme base, moderate, tapering gradually 

 to a narrowly rounded apex. Terminal clasp segment stout, taper- 

 ing and curving strongly to a slender apex 

 b)earing a short, stout apical spine, Claspette 

 a conspicuous subapical process bearing three 

 stout, chitinous processes and three smaller 

 ones but with no trace of a spatulate organ. 

 Harpes divided, the major limb rather stout 

 with a broadly expanded apex crowned with 

 a thick group of stout, chitinous spines. 

 Minor limb about one fourth the length of 

 the major, strongly curved and with a bltmt 

 apex. Harpagones broadly expanded at the 

 base, terminating in a long, slender, blunt, 

 chitinous spine and with a group of short, 

 stout, chitinous spines near the base of the 

 long one. Unci slender, probably approxi- 

 mate, tapering gradually to a broadly rounded 

 apex. Setaceous lobes weakly developed 

 and with about eight long, slender setae. 



Culex concolor Rob.-Desv. Genitalia, 

 male. Basal clasp segment stout, subconi- 

 cal with a broadly rounded apex. Terminal 

 clasp segment rather stout, somewhat enlarged basally and with a 

 rather long, stout apical spine. Claspette a subapical conical 

 internal process bearing four simple, stout, chitinous spines and so 

 far as can be determined with no trace of a spatulate organ. Harpes 

 divided, the main limb long, slender, crowned with a thick group 

 of stout, chitinous spines. Minor limb rather short, stout and at
