Oregus. 



This genus is allied to Mecodema and Metaglymma. 



Mentum not very deeply emarginated, with a broad, scarcely bilobed 

 tooth. Palpi rather short, with the apical joint a good deal dilated and 

 truncated at apex, so as to be securiform. Labrum transverse, truncate 

 in front. Head large and elongate. Thorax cordate, the sides regu- 

 larly rounded, without the posterior sinuation observable in Mecodema, 

 and the hind angles indistinct. Elytra sub-cylindrical. External apex 

 of anterior tibia simple. 



The above characters have been taken from a specimen of O. 

 cereus.
