African PhJebotomic Di'pteva. 355 



margins of band emarginate on third segment (at least in 

 typical specimen) ; anterior extremities of horseshoe-shaped 

 mark visible through hind margin of fourth segment (at 

 least in case of type), so that on a cursory inspection this 

 segment appears to have two small dark blotches on its 

 hind margin; venter shining ochraceous-buff, without 

 markings, clothed with appressed ochre-yellow hair. Wings : 

 markings of same general type as in previous species, but 

 transverse band narrower, and apical blotch reaching 

 posterior branch of third longitudinal vein ; extreme base 

 and costal cells mummy-brown, remaining markings and 

 stigma dark sepia-coloured or clove-brown ; " remaining 

 markings " occupy apex of anal cell, proximal two-fifths of 

 second basal and rather more than proximal half of first basal 

 cell, and also include transverse band and its extension along 

 costa and into second submarginal cell ; first basal cell with 

 usual, minute, hyaline streak at its extreme base ; dark 

 brown blotch in apex of anal cell slightly overflows sixth 

 longitudinal vein into axillary cell ; transverse band starts 

 from hind margin of wing in lower distal angle of fifth 

 posterior cell, passes over posterior transverse vein and is 

 indented in discal cell, then becomes broader and reaches 

 costa, its proximal margin meeting second longitudinal 

 vein slightly basad of distal extremity of auxiliary vein, 

 and its distal margin, which is indented in first submarginal 

 cell, meeting second longitudinal vein slightly beyond level 

 of distal extremity of stigma; from point at which proximal 

 margin of transverse band meets second longitudinal vein to 

 distal extremity of marginal cell latter is entirely dark 

 brown, though (in typical specimen, at any rate) there are 

 traces of an ill-defined paler area in marginal cell immedi- 

 ately above space separating transverse band from apical 

 blotch ; from distal extremity of marginal cell, costal 

 extension of transverse baud is continued downwards to 

 form apical blotch, becoming broader immediately below 

 second longitudinal vein (its proximal margin crossing 

 anterior branch of third longitudinal vein at a point about 

 one-fourth of the length of the branch from its base), and 

 terminating on posterior branch of third vein ; veins orange- 

 ochraceous, costa, auxiliary, and first longitudinal vein, and 

 other veins where covered by dark markings, dark brown or 

 clove-brown. llalteres : knobs orange-buff, stalks buff. 

 Legs buff-yellow or orange-buff ; front tarsi clove-brown, 

 last three joints and tips of first two joints of middle and 

 hind tarsi mummy-brown.
