Prothorax with lateral angles narrowly rounding, 

 with one long hair and a short spine, a series of long 

 hairs on the rounding posterior margin; lateral blotches 

 but little darker on the margins; transverse cliitin bar 

 distinct, but little darker than the fuscous ground color 

 of the prothorax. Metathorax short, lateral margins 

 slightly divergent, a little concave, a short prickle near 

 the posterior angles and a long hair and one short spine 

 in the angle; a series of hairs along the weakly convex 

 posterior margin; lateral blotches distinct, meeting on 

 the median line; darker brown to black on the lateral 

 margins, a pale band on the posterior margin. Legs 

 robust, pale fuscous with darker marginal markings. 

 Sternal markings consisting of a distinct median 

 blotch, with rounded anterior margins, posterior angles 

 projecting backward, posterior margin also produced 

 into a distinct angle. 



Abdomen broadly elliptical, segments with short 

 spines on the lateral margins and a few long hairs in 

 the posterior angles; a series of dorsal, spiny hairs on 

 the posterior margin of each segment; general color of 

 the abdomen dark fuscous; lateral blotches distinct, 

 black on the lateral margins, paler and fading out med- 

 ially on the segments before segment 7; segments 7 and 

 8 with continuous transverse bands; segment 9 wide, 

 with two lateral blotches meeting narrowly on the 

 median line and a paler band on the lateral margin; 

 the last segment flatly rounding; two short hairs on the 

 posterior margin ; ventral markings very similar to 

 those of the dorsal surface, also a similar series of hairs 

 on the posterior margins of the segments.
