segments very narrowly yellow ; pygofer pitch black, anal tube brownish-yellow ; 

 styles pitch-brown, passing into yellow beyond the middle. 



Pygofer : upper notch large and wide, forming about four-fifths of a circle, 

 lower notch as in the other species, outline in the cephalad aspect suborbicular, the 

 aperture square, with rounded angles, but contracted at about half its height by 

 reason of the projection inwards of the sides, hind margin in the lateral aspect 

 straight. Styles slightly sinuate, gradually narrowed from the base to the truncate 

 apex, where the inner angle is produced into a long sharp tooth. Anal tube : 

 aperture suborbicular, lower margin much widened, the lower corners forming two 

 wide, somewhat acute, angles, owing to the wide angular notch of the lower edge, 

 the teeth invisible in the cephalad aspect of the pygofer.

$ . Abdomen above black, its sides narrowly yellow, the hind margin of the 

 last segment narrowly white. 



Pygofer dark brownish-yellow, the upper and lower notches as in C. dorsata, 

 the hind margin, when viewed from the side, rounded ; the periphery, in the cephalad 

 aspect, transversely elliptic. Anal tube brownish-yellow, its aperture suborbicular, 

 somewhat contracted below, its lower edge scarcely perceptibly widened, the lower 

 angles blunt, somewhat rectangular. Styles pitch-brown, yellow at the apex, nearly 

 straight, gradually narrowed from the base to the apex, where they are slightly 

 produced into a short blunt lobe on the upper-side only. Teeth of the anal tube 

 not visible in the cephalad aspect.
