 half-circular lines extend along caput grooves, conjoined in 

 centre of thorax, curving outwards near base ; clothed with 

 a few stout white lanceolate hairs, long erect black one at 

 base of caput ; oval, laterally compressed at caput, which 

 is upturned, sub-conical, reddish-chocolate colour ; four central
