Head about two-fifths again as broad as long; front regularly 

 convex, with erght short prickles: antennae in a narrow, shallow 

 emargination with second joint longest: eye not noticeable, without 

 a prickle; from the antennal sinuses the temporal margins diverge con- 

 siderably and then converge most abruptly forming prominent angles 

 at which are located a short prickle and a long hair: between the 

 angle and the occiput another long hair, and a prickle at the inner 

 end of posterior temporal border; the occipital border is strongly 

 emarginate immediately before the lateral margins of the prothorax 

 with a resulting strong convexity between these. Head color pale; 

 with darker, broad marginal frontal bands, produced posteriorly on 

 each side as a much darker bar, which terminate opposite the hind 

 borders of antennal sinuses: temporal bands interrupted across the 

 bases of antennae but extending from the dark ocular blotches, in- 

 creasingly fainter, to the temporal angles; mandibles and oesophageal 

 sclerite amber-colored: a rather narrow, brown band along the con- 

 cave and convex portions of the occipital margin: broad, conspicuous 

 occipital bands extend nearly to the antennal bands. 



Prothorax trapezoidal, with lateral margins converging somewhat 

 anteriorly, and posterior margin nearly straight; the latero-posterior 

 angles are narrowly truncate, and each bears a strong hair; broad, 

 dark lateral borders. Metathorax in outline resembling an acorn 

 cup. with posterior-lateral regions rounded, and each bearing a long 

 and a shorter hair: posterior margin produced on abdomen as a prom- 

 inently rounded lobe, and bearing a group of six strong spines; an 

 amber-colored yoke-like blotch involves the entire segment, and a 

 broad curving band extends along each side into the first abdominal 

 segment. Legs very pale, with somewhat darker marginal borders. 



Abdomen elliptical, widest on fourth and fifth segments; middle 

 region of abdomen imcolored: faint lateral bands and trigger-shaped, 

 faint lateral blotches on segments three to six, inclusive, which en- 

 croach slightly onto the segments ahead: segments two to six, in- 

 clusive, also with a tad-pole-shaped blotch at each lateral posterior 

 angle; segment one bare of hairs; segments two and three with a 

 prickle at each angle: segment four with two shortish hairs at angles; 

 segment five with two spines and a long hair at each angle, and a 

 strong hair on each side nearly half way to the middle; segment six 

 with two strong hairs at the angles, and a strong hair on each side 

 nearly half way to the middle: segment seven with about eight hairs 

 along the rounded posterior margin.
