African Phlehotomic Diptera, 293 



pnrtly incomplete light border to anal angle ; discal cell with 

 two transverse light marks (the more distal one interrupted) 

 across middle third, and a small and rather indistinct light 

 fleck close to distal extremity ; stigma mummy-brown, well 

 marked and elongate, dark blotch below it not darker than 

 ground-colour; at proximal end of stigma a distinct light 

 mark (process from proximal rosette) running up to costa, 

 and a small light loop (upper extremity of distal rosette) in 

 marginal cell immediately beyond stigma. Halteres : stalk 

 cream-coloured, knob dark sepia. Legs : front tibite scarcely, 

 middle and hind tibiaj not incrassate ; basal half or three- 

 fourths of first joint and extreme base of second and third 

 joints of middle and hind tarsi cinnamon. 



Angola : Benguella, November-December 1904, from the 

 same locality as the following species (JDr. F. Creighton 

 Wellman). 



H(E77iatopota desidiosa is a dusky, although not very dark 

 species, without conspicuous markings on the body ; the 

 coloration of the antennae, simple apical sinuous mark in 

 the wing, widely separated from the distal rosette, and 

 obscurely banded tibiie will help to distinguish it. 



Hmnatopota moJesta, sp. n. 



? . — Length (3 specimens) 8*25 to 9*5 mm. ; width of head 

 2*25 to 2"5 mm. ; width of front at vertex 1 mm. ; length 

 of wing 7*4 to 7"8 mm. 



Dorsum of thorax dark olive-brown, with sides and usual 

 titree longitudinal stripes grey ; dorsum of abdomen olive- 

 brown, sides of segments more or less olive-grey, third and 

 follovAtig segments each usually with a pair of more or less 

 distinct though not sharply defined yelloivish grey or grey 

 admediun spots, often fused or partially fused ivith the grey 

 lateral borders, of which they form an extension tovxirds the 

 middle line ; wings sepia, light markings with a faint yelloivish 

 tinge, usual three rosettes present, rather coarse and sometimes 

 largely fused together, apical sinuous mark slender, not bifur- 

 cate ; legs dark brown, bands on tibia often hardly distinguish- 

 able, front tibia slightly lighter {mummy -brown) close to base, 

 but scarcely banded, middle and hind tibia each with a pair of 

 dull cinnamon bands, sometimes obsolete or nearly so in case 

 of hind iibice. 



Head : front olive-grey, an olive-brown roughly triangular 

 spot on vertex on each side of middle line, face and jowls 

 light gi'cy ; lateral frontal clove-brown spots conspicuous, 

 narrowly separated from eyes, nsedian frontal spot fairly
