CULICES WITH FEET BANDED ON THE ARTICULATIONS 421 



55. CULEX GELIDUS, Theobald (Monog. II, p. 20). 



Tarsi dark, with three pale bands on the fore, and four on the 

 mid legs, the upper ones on the articulations, the lowest basal 

 only ; hind legs banded in the same way as the middle pairs, but 

 iudistinctly. Thorax dusky yellowish-brown to brown, with the 

 front two-thirds covered with frosty-white, curved scales ; the 

 hind portion with almost black scales and long dark bristles. 

 Abdomen brown with basal creamy-white bands and pale lateral 

 spots. Ungues of the $ equal and simple. The proboscis has 

 a broad black band on the apex, so that there is a tendency to 

 pale banding. 



$ . — Head with frosty-white curved scales in front, and upright white 

 ones at the back, sides clothed with ochreous scales, with apparently 

 two yellow bristles at the edge projectmg forwards from, the middle ; 

 palpi with black scales, slightly ochreous towards the base on the inner 

 side. Pleurae pale reddish, with a few black hairs. Legs ferruginous, 

 witli scattered dark scales. Venter yellowish. Halteres with white 

 stem and black scaled knobs. Length — 4"5 mm. 



Habitat. — Straits Settlements and Travancore. Mr. Theobald des- 

 cribes a variety of this species, C. gelidus, var. cuneativs, from the same 

 localities, in which the pale abdominal bands show a median wedge- 

 shaped extension.
