BIONOMICS. — The adults frequently enter houses and are regarded as 

 troublesome biters by some observers, but they do not rival C qumqiiejasciatiis 

 in this respect. The species reaches its greatest abundance during the late win- 

 ter and spring months in the southern states. Larvae and adults occur through- 

 out the year in the southern portion of its range but are rare in southern 

 Florida (4th Sv. C. Med. Lab. records, 1942-1944, unpublished). Larvae are 

 found in a great variety of breeding places, including ditches, pools in streams, 

 rainbarrels and other artificial containers, and woodland pools.

Ciilcx salinarius Coquillett, 1904. Ent. News. 15:73. 



ADULT FEMALE. — Medium sized species. Head: Proboscis dark scaled; 

 palpi short, dark. Broad dorsal region of occiput clothed with narrow pale 

 golden-brown scales and dark erect forked scales, except for whitish scales 

 narrowly margining eyes; lateral region of occiput with a patch of broad whitish 

 scales. Thorax: Integument of scutum brown, covered with fine golden-brown 

 scales, paler on prescutellar space. Pleura with several small groups of broad 

 pale scales, each group usually comprised of more than six scales. Abdomen: 

 Tergites primarily dark brown to black scaled with bronze to metallic blue- 

 green reflection; narrow dingy-yellow basal bands often present and apices of 

 segments more or less distinctly blended with dingy-yellow scales; seventh and 

 eighth tergites frequently entirely covered with dingy-yellow scales; basal lateral 

 patches rather poorly defined and of similar pale scales. Venter yellowish- 

 white. Legs: All legs dark scaled with bronze to metallic blue-green reflection, 

 except for whitish inner surfaces of femora. Wing: Scales narrow, dark. 



ADULT MALE. — Coloration similar to that of female, but with dorsal abdom- 

 inal pale bands much broader. TERMINAlia (Fig. 140). Apical margin of 

 eighth tergite (VIII-T) bearing numerous rather long setae (longer than 

 those of the lobes of the ninth tergite). Lobes of the ninth tergite (IXT-L) 

 widely separated, only slightly raised, each bearing several slender setae. Tenth 

 sternite (X-S) crowned with numerous short pointed spines; basal arm (XS- 

 BA) long, stout, strongly curved, heavily sclerotized. Phallosome (Ph) formed 

 of two large heavily sclerotized plates connected at base. Each plate with a 

 stout sharply pointed dorsal arm (Ph-DA) bent medially at right angle, and a 

 stout bluntly pointed ventral arjn (Ph-VA) bearing a small projection on its 

 inner margin near middle; a group of several closely set pointed teeth (Ph-T) 

 arising between the prominent dorsal and ventral arms. Claspette absent. Basi-
