408 GNATS OE MOSQUITOES — CHAPTER XIII 



the antennae are one-fifth shorter than the proboscis, which is distuictly 

 spatulate beyond the ventral white patch. The palps are subulate and 

 greatly exceed the proboscis in length, and though not distinctly banded, 

 show paler patches at the bases of the joints, and the last two joints have 

 tufts of pale yellow hairs. In both sexes there are small pale knee-spots 

 and apical tibial dots, and the venter is elaborately marked, especially 

 on the hinder segments, with central fawn spots, separated from nearly 

 pure white lateral patches by a narrow black streak curvmg backwards 

 and outwards. The anterior and mid ungues are large and unsymmetrical, 

 each claw being provided with a strong accessory tooth. A variety of 

 this species, C. Mombaensis, having the thorax adorned with paler lines 

 as in Plate xvi, fig. 4d, is distinguished by Mr. Theobald, in his mono- 

 graph. 



Habitat, — Southern and Central Africa, and also Queensland, accord- 

 ing to Bancroft, who calls it the " long-lived mosquito," havmg kept it in 

 captivity for five months.
