African Phlebotomic Diptera. 295 



Angola: three specimens (co-types) from Benguella, 

 November-December 1904- (Dr. F. Creighton Welbnan). 

 The collector writes with reference to this species : — " Six 

 specimens taken in thick bush, 125 miles from coast." 



Hcematopota molest a is not closely allied to any other 

 species at present known to me. From H. inflaticornis, 

 Austen (the original series of which was taken by Dr. 

 Creighton Wellman in Bihe, Angola, 1/5 miles further 

 from the coast, at about the same time as the specimens of 

 H. molesta, and to which the latter presents a certain slight 

 resemblance owing to the abdominal markings), the new 

 species may at once be distinguished, inter alia, by the much 

 narrower head and narrower abdomen, much smaller, shorter, 

 and less swollen first joint of the antennse, darker wings, 

 much larger and more conspicuous stigma, and obscurely 

 banded tibiae. 



H&matojjota virgatipennis, sp. n. 



?. — Length (3 specimens) 10*25 to 12 mm.; width of 

 head 2'6 to 3 mm. ; width of front at vertex 1 to 1*4 mm. ; 

 width across base of second segment of abdomen 2"25 to 

 2*6 mm. ; Avidth across base of seventh segment of abdomen 

 1 to 1*25 mm. ; length of wing 8'5 to 9*5 mm. 



Elongate species, with tapering abdomen, and a conspicuous 

 pale longitudinal streak in middle of wing. — Dorsum of thorax 

 dark olive-brown, with usual three longitudinal stripes olive- 

 grey or yellowish grey ; dorsum of abdomen yellowish grey, 

 second and tivo following segments each with a pair of very 

 conspicuous, bachwardly directed, admedian dark sepia blotches; 

 wings sepia, usual three rosettes present, but partly obscured 

 by the pale longitudinal streak, which extends from either base 

 or distal extremity of first basal cell to apical sinuous mark, 

 where latter meets lower branch of third longitudinal vein ; 

 legs pate mummy-brown to cinnamon, front tibial ivith a single 

 more or less indistinct pale band close to base, middle and hind 

 tibice each with two pale bands. 



Head : front dark brown, lateral borders (which expand 

 on vertex), a ring surrounding each lateral frontal spot, and 

 a median stripe extending from median frontal spot to 

 occiput yellowish grey or olive-grey ; face and jowls light 

 grey, a more or less distinct small dark spot below each 

 antenna and sometimes indications of a horizontal dark 

 brown streak between lower inner margin of eye and antenna 

 on each side ; lateral frontal clove-brown spots large, con- 

 spicuous, not in contact with eyes, median frontal spot small 

 but distinct ; frontal callus mummy-brown in centre, dark 

 sepia at sides, of moderate depth or somewhat narrow from
