This species differs from M. barbatus, King, by the shape of 

 the body, which is more elongate and more attenuate in front, 

 and by the prothorax, which is opaque and has a dense and rugose 

 punctuation.

Closely allied to M. barbatus, King, but larger; the antenna? 

 are thicker and the club is stronger. 



I have much pleasure in naming this insect after Mr. Masters, 

 to whom I am indebted for it.
