have a marginal fascia of snow-white scales ; in the centre the 

 bands are formed of single scales placed longitudinally, at the 

 sides the bands are much widened and are continued beneath, both 

 above and below usually more or less interrupted ; the abdomen is 

 rufo-testaceous beneath ; the superior plate of the apical segment 

 gradually narrows to a point, has a short carina towards the apex, 

 and a white spot on each side about the middle ; the lower plate 

 is nearly twice the length of the upper, gradually tapering and 

 notched at its apex. 



The male only differs in the apical segment of the abdomen 

 which is armed with eight spines, a short acute one on each side 

 at the base, four short acute ones in a row at the apex above, and 

 two longer ones beneath ; there is also a very minute one on the 

 apical margins of the fifth segment at its extreme lateral angles.
