U. insignis was originally described by Pocock as a distinct species 

 but was subsequently regarded by him as a melanistic subspecies of 

 lineatus. U. insignis is not, however, more blackened than the 

 ■darkest specimens of lineatus from the Cape Peninsula, except on 

 the vesicle and inferior surface of the cauda, and it differs in colour 

 from such specimens principally in the following points : (1) The 

 yellow >< -shaped marks are as distinct on the anterior as on the pos- 

 terior abdominal tergites, whereas in lineatus these marks are always 

 more or less resolved into a pair of irregular yellow blotches in the 

 anteriormost tergites at least ; (2) the anterior caudal segments are 

 provided with a pair of longitudinal black stripes below divided by a 

 fine median yellow line (in lineatus the under side of the anterior 

 segments is yellow with a fine median black line, which generally 

 extends over the last abdominal sternite as well) ; (3) the vesicle is 

 deeply blackened on the sides and below, and provided below with 

 two narrow, and on each side with a broader, lateral, yellow, longi- 

 tudinal stripe, the upper surface more lightly infuscate in the middle 

 part (in lineatus the vesicle is always ochraceous, with a narrow 

 inferior median line and the anterior lateral angles darker or lightly 

 infuscate, the sides also often with faintly infuscate stripes, two such 

 stripes when distinctly marked corresponding on each side to the 

 single broad infero-lateral black area of insignis). 



In insignis the tubercle below the aculeus, although always dis- 

 ■tinct, is, as already noticed by Pocock, smaller and weaker than in
