428 GNATS OR MOSQUITOES — CHAPTER XIII 



ber of species included, it will be more convenient to deal with 

 each category separately. Of the eight types of abdominal mark- 

 ing, all are represented except the fifth, vii^., that in which the 

 abdominal segments have pale bands, both at base and apex. 



The group is accordingly subdivided as below : — 



i. Abcloininal segments with pale basal bands and more or less 

 distinct lateral spots. 

 ii. With basal pale bands and longitudinal stripes, median or lateral. 

 Hi. With basal pale bands only. 

 iv. With apical pale bands. 

 vi. Unhanded, but witli lateral spots. 

 vii. Unhanded, but with a pale median line. 

 via. Quite unadorned. 



It must be understood that it is not necessarily implied that 

 ALL the segments are thus marked, but that, in each case, a 

 greater or less number of them conform to the description. 



Subdivision i. — Culices luith unhanded tarsi and the ahdomoi 

 ornamented with pale basal hands together loith lateral spots. 

 Four species only conform to this description. 



70. C. univitatiis, Theob. The tibiae have broad white apical bands, 



especially well marked on the hind legs. Head brown, with 

 one white patch. 



71. C. quasiunivitatus, Theob. Closely resembles the above, but 



has two black patches on the head. 



72. C. restuans, Walker. Tibiae without apical pale band. Two 



pale round spots on the mesonotum. Tarsal claws of $ , 

 equal and simple. 



73. C, australis, Erichson. Tibiai without apical band. Meso- 



notum clothed with golden scales, arranged more or less in 

 lines. Tarsal claws of $ , equal, but with extra tooth. 



70. CULEX UNIYITATUS, Theobald (Monog. II, p. 29). 



Legs with the tarsi uniformly coloured, but with broad white 

 apical bands on the tibia;, most marked on the hind legs. 

 Thorax deep brown, with scattered golden curved scales ; 

 Bcutellum with three patches of pale, sometimes silvery, scales. 

 Abdomen brown to purplish-black, with more or less basal white 

 banding, sometmies rather yellowish, and with triangular basal 

 white lateral spots. 



Head brown, with creamy linear curved, and dark erect forked scales ; 

 the lateral flat scales creamy-white, with a bare hne ua the middle ;
