 narrow brown carina above, expanding and ceasing in a 

 small triangular spot between the antennas ; the sides of the 

 head nearly to the level of the upper part of the eyes are 

 black ; face testaceous, a transverse reddish mark in front 

 below the level of the antennas ; palpi reddish brown, the

 eleventh joint and then black, with pale rings towards the 

 base of the twelfth segment, and on the extremity and base 

 of the fourteenth and fifteenth and sixteenth and seventeenth

 second joint, and base of the third are thickened ; the third is 

 nearly as long as the fourth and fifth together, the fifth being the

 is a little shorter than the preceding ; all the joints beyond 

 the second are long and cylindrical. Prothorax and meso- 

 thorax testaceous above, with a median groove; the thorax, 

 below the lateral carinas, and the abdomen are black. The 

 hinder two-fifths of the mesothorax is raised; the front part is 

 bordered on the lateral carinas with a row of short sharp 

 spines, the flat space between being sparingly and irregularly 

 granulated. The tegulas are humped, strongly reticulated, 

 and testaceous yellow inside to the summit of the hump, and 

 black outside. The wings are dark reddish brown on the 

 costal area and greyish brown on the membranous area. 

 The legs are testaceous, the femora black, testaceous at the 

 tips beneath on the first four femora, and wholly so beneath 

 on the hind femora. The trochanters and coxas are wholly 

 blackish. The terminal segments of the abdomen are
