 Upright forked scales of 

 a Mansoftia major 

 b MansoHia itni/ormis 



The specimens show great variatiou iu size. Tlie large 

 ones look very like Mamonia luajoi; Theobald (Mono. 

 Culicid. III. p. 270) Init the forked cephalic scales have 

 mostly only one median spine, Ijut may ha\-e two as in 

 J/. maj(>i\ but the lateral spines are equal not unequal. This 

 character I neglected to point out before. For figures of 

 wing, vide Plate II., Fig. 3, and Plate IV., Fig. 1. 



Dr. Balfour writes that this species "becomes common 

 and remains so shortly after i^assiug Wad ]\Iedaui on the wav 

 South." 



It is widely distributed i>\er Central, Xorthern, East 

 and \Vestern Africa, and also in India and the Philippine 

 Islands. I have had none from the Transvaal, Orano-e 

 River Colony or Cape Colony.

 No fi'esh specimens have been received since the one sent me by Capt. 

 Cummins taken in the Bahr-El-Ghazal. 



It is larger than the largest of the preceding species reaching fi.5mm. in 

 length. It can be told by the upright forked cephalic scales hax'ing the thin 

 lateral spines unequal and by their irregular form and the " border scales " 

 on the wing being all dull yellow Avhilst iu J/, unifonnis they are in alternatino- 

 patches of dull yellow and black.

To'iitiifhi/nchus aurites, Theobald 

 Mono. Culicid. II, p. 209 (1901) and III, p. 269, (1903). 

 This species occurs in fair numbers on both the Blue and White Niles. 

 Dr. Balfour took thein between Roseires and Sennar on the Blue Nile, at Bahr-El- 

 Jebel North Sudd country on the White Nile 



It also occurs in Uganda and on the West Coast at Bonny and iu the 

 Federated Malay States.

 Mono. Culicid. II, p. 205 (1901) 

 A single female with body gorged with blood and denuded of scales thus 

 appearing black. Tlie sixth dusky scaled long vein is prominent and clearly 

 defines it from the former species. 



Taken at Lake No, White Nile. Dr. Balfour adds a note ■ " femora spotted 

 black," I cannot detect the spotting in the specimen he sends. This beautiful 

 species has also been taken in Old Calabar.
