6. Anopheles [MyzorhyncTius) hancroftii^ Giles. 

 Appears to be common. 



I leave the name, as these specimens are not in the best 

 condition, but for my own part I am convinced there is no 

 difference between this species and A. barbirosfris, V. de 

 Wulp. The spots in the fringe are not merely variable in 

 this and otlier species of the subgenus, but also they depend 

 to some extent on the angle from which the ligiit is 

 reflected. 



7. Anopheles {Nyssorhynclius) annulipes^ Walker. 



This specimen has been compared with those in the 

 British Museum (Nat. Hist.) and differs only in having 

 scales on all the abdominal terga. Scales are extremely 

 scanty on the first tergum, slightly more numerous on the 

 second, still more numerous on the third, and fairly abundant 

 on all the rest. If the artificial classification of Theobald 

 were adopted this specimen would be included in the 

 " genus '' NeocelUa. There seems good reason to suppose 

 that in the subgenns Nyssorhynchus, using the term in a wide 

 sense, to include all the forms catalogued by Theobald under 

 Nyssorhynchus, NeocelUa, and Cdlia, the amount of the 

 scaling on the abdomen is often a fluctuating and inconstant 

 character.
