Colour chestnut-red, banded ; I stout, cylindrical and the 

 longest, with a few short, stout spines ; II stout, cylindrical 

 and the shortest, with a few quite inconspicuous spines; III- 

 XVIII attenuated obconic ; III with one whorl of bristles, 

 rest with two ; joint XIX oval and comparatively small, as a 

 rule as long as III. In the XlX-jointed antenna3, III is 

 longer than II or IV, V shorter and narrower than IV and 

 much shorter than VI. 



Gula a little darker than ventral genge ; lateral sutures 

 brown ; less than one-quarter the width of the head ; sides 

 pai-allel, slightly incurvate. Free apex narrowed with distal 

 margin straight and oblique incurved sides. 



Ventral genee with post-gense represented by pale ochra- 

 ■ceous areas. 



Thorax. — Diffuse ochraceous-brown, each shield with a 

 I)lack outline ; sides of shields somewhat up-bent. 



Pronotum sellate, narrower than head; median cephalic 

 margin bilobed and acutely elevated; cephalo-lateral pro- 

 cesses rather acutely rounded; sides straight converging; 

 caudal margin broadly bilobed ; caudo-lateral corners broadly 

 rounded. 



Mesonotum not quite as wide as pronotum ; sides angled, 

 at first curvate and diverging, then converging and straight 

 or faintly incurvate and merging broadly into caudal margin ; 

 ■caudal margin incurvate, nearly straight. 



Metanotum shorter and wider than mesonotum : sides
