African Phltlotomic Diptera, 113 



occupied by an upAvard prolongation from proximal rosette. 

 Halteres as in H. stimulans. 



Nyasaland Protectorate : type and five other specimens 

 from the B Ian tyre District, May 1905 (Dr. J. E. S. Old) • 

 an additional specimen forwarded in 1905 by Major F. B. 

 Pearce, with the following note : "Especially virulent species; 

 complained of by natives as injuring, if not actually killing 

 their cattle." 



In fades, conspicuously spotted abdomen, and the faint 

 colour and markings of the wings, H. noanalis agrees with 

 H. brunnescens, Rioardo, a species which is common in 

 Uganda, but also occurs in the Nyasaland Protectorate ; the 

 new species, however, is distinguished by the shape of the 

 antennae, and by the absence of a broad mummy-brown bar 

 between the eye and antenna on each side, and of a median 

 grey stripe on the dorsal surface of the abdominal segments. 

 From both H. stimulans and H. insidiatrix the present species 

 is distinguished at once by the breadth of the pale band on 

 the front tibiae; while it differs from H. malefica, apart 

 from the paleness of the wings and other characters, in the 

 wing-markings being much less broken up, the broader 

 front, much shorter first antennal joint, shallower frontal 

 callus, &c. 



Hcematopota furtiva, sp. n. 



? . — Length (4 specimens) 9 to 9 - 4 mm. ; width of head 

 3 to 3\2 mm. ; width of front at vertex just over 1 mm. ; 

 length of wing 8 mm. 



Dark olive-brown ; markings of dorsum of thorax and abdo- 

 men olive-grey, as in 11. stimulans, Austen, though median 

 stripe on abdominal segments usually broader, and admedian 

 spots generally larger ; wings sepia-coloured, light markings 

 closely resembling those exhibited by the wings of H. stimulans, 

 except that loop and zigzag mark in axillary cell are not 

 connected ; legs as in H. stimulans, except that middle and 

 hind femora are paler (buff-coloured), that band on front tibia 

 is pater (cream-coloured) and slightly broader, and that distal 

 two-thirds of front tibia are distinctly swollen. 



Head: front yellowish grey, its sides nearly parallel, face 

 and jowls smoke-grey; frontal callus clove-brown or black, 

 about 0"5 mm. in depth, extending from eye to eye, upper 

 and lower margins straight or nearly so, though upper 

 margin sometimes apparently curves slightly downwards at 

 sides ; a dark seal-brown median spot below and in contact 

 with callus ; lateral frontal clove-brown spots rather small,
