 longer, nearly equal; anal still longer. Segments 2, 3, 5, 6, 9, 

 11 and 13 black, except the anterior and posterior edges of 3 

 which are narrowly yellow; the black of these segments continues 

 on the venter, but is supplemented with yellow on anterior and 

 posterior edges; 4, 7, 8, 10 and 12 yellow with orange-colored 

 chaetiferous tubercles, while the black segments have shining 

 black tubercles, with a steel bluish or purplish luster. All the 

 segments except head bearing long black bristly hairs from the 

 tubercles, the head with a few hairs along edge and several very 

 short ones on dorsum. Three thoracic segments with six dorsal 

 tubercles, all the other segments except anal with twelve; 2 with 

 six black tubercles; 3 with the two median and one lateral on 

 each side black, and the one sublateral on each side orange; 4 

 with all six orange; tubercles on other segments are all concol- 

 orous with those segments. The posterior median pair of tuber- 

 cles on 5 to 12 each bears a dense brush of short bristles of same 

 color as the tubercle from which they spring, in addition to the 

 long bristly hairs. Anal segment with six anterior, and six 

 smaller posterior black tubercles, the posterior three on each side 

 not in a transverse row like the anterior ones, but arranged in a

 edges of venter. Length, 28 mm.; greatest width, 8 mm.
