 Description. presented in different positions to the light, 



giving them the appearance of being 

 coated in silk. This easily distinguishes it from both 



obesus and Hoplocerambyx 

 with which forest officers are liable lo 

 confuse it. The head has a straight or 

 very feebly bisinuate furrow beneath be- 

 f.vcen the cheeks, this distinguishing it 

 from . A . indiita. The prothorax is 

 rounded at sides and irregularly wrinkled 

 above, with a smooth space on disk.
