brown, connected by a narrow even line on the occip- 

 ital margin; a dark broad occipital signature showing 

 through the head. 



Prothorax short and wide; two short spines in the 

 anterior margin and a series of four long pustulated 

 hairs and one short spine on each rounding lateral and 

 posterior margin; transverse and longitudinal chitin 

 bars distinct; median portion of the prothorax pale 

 anteriorly, but darker fuscous towards the posterior 

 margin; lateral portions, beyond the longitudinal chitin 

 bars, dark fuscous. Mesothorax narrow; posterior 

 angles distinctly angular, with a long hair and spine; 

 dark transverse band on the posterior margin, dark 

 longitudinal chitin bars extending from the anterior 

 angles across the mesothorax; a second pair of chitin 

 bars extending from the anterior, lateral margins back 

 across the metathorax. Metathorax narrow, appearing 

 like the first abdominal segment; a long hair and two 

 spines in the posterior angle; a dark brown transverse 

 band across the lateral margin. Sternal markings con- 

 sisting of dark intercoxal lines, a median blotch on the 

 prothorax, with the posterior angles produced laterally, 

 meeting narrow dark chitin bars which extend forward 

 to the anterior margin; the posterior margin of the 

 blotch also produced in an angle; a broad brown median 

 band between the second and third pair of legs, also 

 extending onto the first abdominal segments; a few 

 scattered pustulated hairs on this band. Legs large, pale 

 fuscous, with narrow dark borders and scattered hairs. 



Abdomen broadly ovate, the poles broadly truncate; 

 posterior angles projecting, with one or two long hairs 

 and a short spine; segments narrower on the anterior 

 half of the abdomen; a few hairs on the posterior 

 margin of the segments; entire abdomen a dark rich
