golden brown; clypeal signature very pale brown but 

 distinct, anterior margin slightly concave; antennal 

 bands interrupted at the suture, darker chestnut-brown 

 at the posterior extremities, which are turned almost at 

 a right angle with the anterior half and lie half way 

 between the mandibles and base of the antennae; dis- 

 tinct, angularly contorted, inner bands paler than the 

 antennal bands; occipital bands pale anteriorly, grow- 

 ing darker and more sharply defined near the occipital 

 margin. 



Prothorax quadrangular, with rounded posterior an- 

 gles, with one long hair; sternal markings showing 

 through as dark bands near the lateral margins, bend- 

 ing inwardly before the posterior margin, and separated 

 by a distinct, uncolored median line. Metathorax with 

 convex, divergent sides, a long slender hair and a 

 prickle on the lateral margin, near the posterior angle, 

 three long hairs in the posterior angle; a series of hairs 

 along the rounding, posterior margin. Legs pale 

 brown, with a few scattered spines. / 



Abdomen broadly elliptical, narrowing at both ex- 

 tremities; a few long hairs in the posterior angles of 

 the segments; a transverse series of hairs on the poste- 

 rior margins of the segments; segments 5, 6 and 7 

 narrowed in the middle; last segment narrowly round- 

 ing, pointed, with two long hairs on the posterior mar- 

 gin; ground color very pale golden brown; transverse 

 lateral blotches indistinct, separated by a broad un- 

 colored median space, except on segment 5, where 

 the transverse band extends across the entire segment; 

 segments 6, 7 and 8 with a broad median blotch of 

 darker golden brown; segment 9 entirely brown; there 

 are but slight indications of defined lateral marginal 

 bands; genitalia distinct, dark golden brown, broad 

 and complex.
