number and some of them rather long but thin, being placed at the distal (or 

 apical margin). The ninth sternite is very unlike that of every other known African 

 species. Its horizontal arm strongly widens apically, the ventral margin remaining 

 nearly straight to the apex, while the dorsal margin gradually runs upwards, 

 forming an acute, bnt slightly rounded, angle with the gently conve.x distal 

 margin. The ventral angle is produced downward into a sharp tooth. The 

 segment has only short bristles, a row of seven or eight being placed at the 



ventral margin and a patch of about sixteen dorsally near the apex. ? . The 



seventh sternite (text-fig. 26) bears on the two sides together in our single 

 specimen an interrupted row of thirteen bristles, and in front of the row twelve 

 additional bristles. The segment is deeply divided by a very large sinus into a 

 broad upper lobe and a short lower one. The upper lobe is truncate-sinuate, with 

 the upper angle strongly rounded, the ventral angle produced (much as in Ct. enqis), 

 and the ventral margin horizontal. The lower lobe is much shorter than the upper

one, and its upper margin is strongly slanting, being dilated into a very small, 

 obtuse additional lobe near the uj)per lobe. The eighth tergite has no bristles 

 above the stigma. There is a ventral row of six bristles on this segment (VIII. t.), 

 of which the first is small and the last two, which are long and differ but sligiitly 

 in size, are placed -close together at the apical margin, which is incurved. Above 

 the row there is one long bristle accompanied by two or three smaller ones, while 

 the inner surface bears one or two short but fairly strong bristles and two or three 

 exceedingly small ones. The anal sternite has eight bristles on the two sides 

 together. [The receptaculum seminis has accidentally been destroyed in mounting 

 the specimen.]

 The nieso|)lcnra of this example bear nine or ten bristles, and the seventh alidoniinal 

 tergite lias three antepygidial bristles on one side and four on the other; the 

 seventh sternite also being slightly different on the two sides of the body. The
