Extremely like 0. muticus, Macl., differing fVoni it cliietly by 

 the well-detined triangular emargination of the front of the 

 clypeus. There is no trace whatever of transverse carina- on the 

 head, and the prothorax (except under a high power) appears 

 quite devoid of punctui-es. On either side of the prothorax 

 there is a tubercle, but scarcely a fovea. The smaller examples 

 nave the front tibiae more slender than the larger ones, and less 

 strongly toothed ; they are no doubt the males. 0. inermin, 

 MaoL, also resembles the present in.sect, but it also differs in tlie 

 lont of the clypeus being entire, and moreover it is a more 

 nitid species.
