on the belly, all of them thickly furnished with long 

 radiating hairs curved a little upwards at their tips. 



The head is black and lustrous, the ground colour 

 of the back a bright primrose yellow, which appears 

 but little on the second segment, being there merely an 

 edging and fine dorsal division to a blackish-grey mark ; 

 this yellow is a little more seen on the third and fourth 

 segments, where the large pairs of tubercles in front 

 are black, the smaller ones behind them bright orange, 

 the space between these on the fourth segment trans- 

 versely barred with black, which more or less tinges 

 the dorsal stripe, and produces a conspicuous central 

 triangular or cruciform black spot ; the complex broad 

 dorsal marking widens a little (diamond-like) on the 

 middle of each following segment, and is composed of 

 a fine broken grey outline, followed within by a line- 

 like interval of the yellow ground, and then with 

 freckles of bluish-grey edged with darker grey, and 

 having a middle delicate thread-like interval of the 

 yellow; near the subdorsal region, run double fine 

 broken lines of grey freckles, which on the front of 

 the fourth segment are absent, but only interrupted 

 on each of the other segments as they approach the 

 bright orange tubercles placed in twos, i. e. a very 

 small roundish one in front, and a large one trans- 

 versely oval just behind it.* Besides the thoracic black 

 tubercles mentioned, others occur on the eighth, 

 twelfth, and thirteenth segments, as follows : — The 

 small front tubercles on the eighth are black, and just 

 there the dorsal region is also more or less black, 

 together forming a conspicuous trilobed spot ; on the 

 twelfth is a greater suffusion of the black, in which 

 both large and small tubercles are dyed ; the tubercles 

 on the front of the thirteenth segment are also black, 

 the anal flap is dark brownish-grey, blotched with 

 blackish and sparingly freckled with yellow ; the 

 yellow ground of the back is very effectively relieved 



* In the females these tubercles are deep orange-red, and the dorsal 

 markings more decidedly of a diamond shape on each segment. — W. B.
