Female. — Head light brown with many long light brown upright forked scales ; 

 clypeus grey, antenna? light brown with light and dark hairs. Palpi (Fig. 4) 

 lightly scaled with two white bands, one at the junction of the middle with the 

 upper third and the second at the junction of the middle and lower third. 

 The apex is dark. 



Thorax yellowish brown covered with pale curved hairs and scales. The 

 sides of the meso-thorax are greenish in some lights ; scutellum is brown with 

 a few curved scales. 



Abdomen, greenish with darker patches, is covered with light brown hairs. 



Legs are brown with faint yellow bands at all the joints. 



Wing (Fig. 5), the costa has four black spots, the basal spot being the longest. 

 The sub-costal has one black spot near its termination. 



The 1st long vein has four black spots corresponding to the four on costa. 

 The remainder of the wing field is pale. The wing fringe is dark. There are 

 no pale patches. 



Male is much paler than the female, the upright forked scales on head are more 

 prominent. The palpi are exceedingly pale, there are practically no bands ; 

 thorax and abdomen same as in female. 



Legs are brown with yellow areas at the joints ; fore ungues unequal and 

 uniserrated. 



The wing has the same markings as in the female. 



Genitalia. — Basal segment medium sized covered with light brown hairs, 

 apical segment narrow, much curved and terminating in a point. 



Larva. — Head brown, thorax dark, body almost black with some light 

 mottling. 



Frontal hairs are simple and unbranched. Antennae have a spine on the 

 outer border about midway. 



Cephalic ornamentation same as that of Anopheles tibani (below). Palm- 

 ate hairs extend from 1st to 7th segment inclusive with modified hairs on the 

 thorax. The blade is long with no definite shoulders (Fig. 6) and is serrated 

 more on one side than on the other. The filament is as long as the blade. 



Eq<j (Fig. 7) is boat shaped with a narrow striated frill, it is encroached 

 upon by the floats, which are well marked almost meeting in the middle 

 line. 



Habitat and Observations. — This anopheles was first found breeding in a 

 spring near D'thala. It was never found in any of the wells around D'thala. 

 At Hardeba it breeds in the spring from October to April. It was found in 

 the tents at Sulek in January 1905 and was breeding in the well 50 yards below 



the Camp. 



This anopheles was also found at the new camp at Nobat, which is 1 j miles 

 from the river. It was then biting freely and was, I am sure, carrying the 

 malaria parasite, though this was not definitely settled. Specimens of this 

 anopheles were sent to Mr. Theobald, who informed me it was undoubtedly 

 a new species, bat related to Anopheles nili described in the First Report of
