punctate, with sulfate medial line, and much less cylindrical in form

 palpi securiform, of labial triangular, eyes large; prominent, in 

 cf close in front, wider behind, in S separated by a space about 

 half the diameter of one, antennae very thin, joints linear, 4-11 sub- 

 equal. Prothorax widest at base, gradually narrowing to apex, 

 sides rounded and a little deflexed anteriorly, posterior angles 

 acute, narrowly margined throughout (not evident from above on
