African Phlehotomic Diptera. 1J3 



occupied by an upward prolongation from proximal rosette. 

 Halteres as in H. stlmulans. 



Nyasaland Protectorate : type and five other specimens 

 from the Blantyre 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, conspicuovisly spotted abdomen, and the faint 

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

 H. hrunnescens, Ricardo, 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 

 antennse, 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 tlie pale band on 

 the front tibise; 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. 



Hamatopota furtiva, sp. n. 



9 . — 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 H. stimulans, Austen, though median 

 stripe on abdominal segments usually broader, and admedian 

 spots generally larger ; icings sepia-coloured, light markings 

 closely resembling those ej;hibited by the wings of H. stimulans, 

 except that loop and zigzag mark in axillary cell are not 

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

 hind femora are paler [buff-coloured), that band on front tibice 

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

 two-thirds of front tibice 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,
