TWO NEW SPECIES OF AFRICAN FRUIT-FLIES. 75 



tijpical specimen at any rate, there is a median burnt-umber-coloured streak on 

 termincd segment; icings hyalijie, with four separate dark hrown markings 

 (occupying much less of icing -surface than in case of dark markings on wing of 

 foregoing species), and not speckled with clove-brown near base ; tibice and tarsi 

 buff-yellow, femora, base of middle tibice and rather less than proximal half of 

 hind tibice clove-brown. 



Head : occiput clove-brown, with exception o£ sharply defined and relatively 

 broad posterior orbits, which are very conspicuous when head is viewed from 

 behind ; front with clove-brown transverse band immediately below ocellar 

 trianole, sides of which it encloses ; face and area below eyes clove-brown, 

 except an extremely narrow whitish streak in each antennal groove, an 

 equally narrow yellowish line next the eye on the lower facial orbit on each

side, and a narrow, ill-defined, yellowish, transverse line, interrupted in 

 middle, across centre of face ; ^xt/jt^i and proboscis clove-brown ; antenjice 

 uniformly clove-brown, arista pubescent, cream-bufF at base ; cephalic bristles, 

 like macrochset^e on body, black ; postorbital bristles on upper third of 

 posterior orbits conspicuous against the straw-yellow ground. Thorax : dorsum 

 clothed with minute black hairs, and with a single transverse band of similar 

 yellowish hairs in front of transverse suture ; humeral calli and oblique stripe 

 on mesopleurse clothed with Naples yellow hair ; scutellum uniformly Naples 

 yellow, entirely without dark markings. Abdomen : hair on dorsum entirely 

 black, except on hind border of first segment, which is thinly clothed with 

 whitish or pale yellowish hairs. Wings hyaline at base, as also throughout 

 greater portion of their surface ; starting from costa where it is joined by 

 humeral transverse vein^ a dark brown transverse band runs down into lower 

 angle of anal cell ; next dark brown mark is also a transverse band (wider 

 than previous one ])ut much narrower than corresponding band on wing of 

 C.pulchella), base of which also rests on costa, fills distal portion of third costal 

 cell (stigma), and extends into distal extremitv of second costal cell, on
