8. S. fraseri, sp. n. q . 



One female from Mpumu Forest, Uganda, July, 1910 (Capt. A. D. Fraser, 

 R.A.M. C), differs in so many small particulars from S. apicoargentea, that it is 

 thought advisable to separate it as a distinct species. A complete description 

 does not seem necessary, but so far as observable all the points of difference 

 between it and the preceding are given : 



Fig. 2. — Stegomyia fraseri, sp. n. Head and thorax, and 

 apex of abdomen ( 9 ). 



Scutellum with the lateral lobes entirely clothed with silvery white scales 

 and a similar large central patch on the median lobe. Scales bordering the 

 bare space in front of the scutellum yellowish. Mid and hind femora in front 

 with the apex white, without any silvery metallic lustre. ' Basal half of hind 

 femora silvery white in front, basal two-fifths yellowish white behind. Hind 

 tibiae with a white mark as in S. apicoargentea, but in this species it is connected 

 with a large yellowish patch at the base beneath. Last joint of hind tarsi almost 

 all white. 



Several of the above characters show that this species is more or less inter- 

 mediate between S. apicoargentea, S. poweri and 6'. pseudonigcria, being at once 

 distinguished from the last two by the abdominal markings, and the shape of the 

 spots on the thorax.

 usually continued as two very fine lines of yellow scales across to the front of the 



* Since writing the above notes, I have found that the female claws of this species are variable. 

 I had inadvertently overlooked Theobald's statement that the claws of S. simpsoni are all simple, 

 but an examination proved this to be quite correct as regards two Transvaal specimens. Some 

 others, however, from Abyssinia, though otherwise indistinguishable from the type of S. simpsoni, 

 have toothed claws. This of course invalidates the genus Howardiua, which must in conse- 

 quence sink under Stegomyia.
