Male. — There are many broad upright forked scales on the head, otherwise 

 the cephalic ornamentation is the same as in the female. Palpi (Fig 8) have 

 three, often four white bands, the basal, the smallest is often very indistinct, 

 the central is longer, and the apical the same as in the female, is often divided 

 into two. These are not complete bands as in the female ; antennae have 

 marked club-shaped ends, which are covered with dark bristles. 



Thorax is black with a frosty appearance. The scales are the same as in the 

 female. 



Abdomen is black, the last segment alone has a few flat scales on its sides. 

 Genitalia, medium sized basal segment, apical segment is dark tapering to a 

 fine point. 



Wing same as in female, legs also the same, ungues unequal and uniserrated. 

 Larva. — Head dark brown to black, thorax and abdomen also dark brown. 

 Cephalic ornamentation is shown in Fig. 11. The antennae have a small spine 

 situated on the outer border ; frontal hairs are simple and unbranched. 

 Palmate hairs are present from 2nd to 7th segment inclusive. Blade (Fig. 12) is 

 long with marked serrations on one of the shoulders, the other has generally 

 one notch. The filament is long and pointed. 



Egg (Fig. 13) boat-shaped with long narrow floats which extend almost to 

 both ends. They extend up to the frill which is narrow and not marked. The 

 floats do not approach each other in the middle line. 



Habitat and Observations. — This anopheles is found in all the rivers and 

 springs in the Hinterland as far up as Jehaf (6,800 ft.). It only breeds in 

 running water and pools connected with it. It was never once found breeding 

 in any of the wells. It is a wild species and does not come to human habita- 

 tions. Experiments were made at D'thala to see if the malaria parasite 

 (Benign Tertian) would develope in this species, but a negative result was 

 obtained. Mr. Theobald agreed with me that though it is closely related to A. 

 theobuldi, it is a distinct species. 



The main differences are as follows : 2£-2f hind tarsi are white, while only 

 the last two are white in A, theobaldi, the frontal hairs are unbranched and 

 the palmate hairs are only found 2-7th segments, the terminal filament of each 

 blade being long and pointed. 



Anopheles (Myzomyia) jehafi n. sp. 



Palpi, dark with four bands, thorax brown with many curved hair like scales ; 

 abdomen dark brown, legs brown, pale at all the joints. 



Female. — Head dark, occiput and nape covered with broad upright forked 

 scales, on each side of vertex, there are a group of silvery upright forked scales 

 and scattered all over, there are many narrow curved scales. There are a tuft 

 of dark bristles spreading over the clypeus on each side. Antennae dark, clypeus 

 black. Palpi (Fig. 14) are densely scaled with four white bands, basal band 

 narrowest, central the broadest, the other two are small. The apical band is 

 often very small.
