Female. Head brown, clothed with rather dense pali' narrow-curved scales 

 whicli lie uniforndy pointing forwards, a few still [)aler \ery small Hat scales

 brown according to the niys of light ; palpi thick, thrc'e distinct small basal 

 segments dull testaceous, tlie fat apical segment as long as the three basal ones and 

 black scaled; there may be a minute nipple-like apical segment, but if so it is 

 hidden in scales; proboscis and clypeus deep brown. 



Tiiorax dark brown, ornamented with dull golden and deep rich brown 

 uarrow-cm'\ed scales ; the dark scales form two prominent o\al areas, one in 

 front of the base oi each Aving, the dull golden scales bordering them : the 

 latter arc also more ov less placed in lines along the middle of the thorax and 

 othei-s at the sides abo\'e the pleune, others, almost creamy, in front of the 

 scutellum : scutellum paler brown than the mesonotum, with pale uarrow-cm'\-ed 

 scales and black border-bristles, se\"en to the mid lobe ; metauotum black :

 cousitlerably longer and slightly narro^ver than the second posterior cell, its 

 base much nearer the base of the wing than that of the latter, its stem short, 

 rather less than one-fourth the length of the cell : stem of the second posterior 

 about two-thir<ls the length of the cell: ju/sterior cross-vein rather more than 

 its own length distant behind the mid cross-vein : halteres with n-ddish-browu

Habitat. Senuar, Blue Xile. 



Ob.servation.'i. — Described from a -ingle female. it resembles at lirst sight 

 C. fatiyans but the i)aler scaled head and the numerous long ui)right forked- 

 scales separate it. the thorax too is distinctly ornamented, the two dark ocellate 

 areas being most noticeable. The palpi may be fiAX'-jointed, but are heavily 

 scaled so that a small apical segment caimot be seen, the three small basal segments 

 are very distinct. Thi' last tarsals are gone so that the characters of the 

 uugues cannot Ije given.
