from the base, but on each side of the base, at a short distance from 

 it, and midway between the suture and the rounded humeral parb 

 there is a round, somewhat small impression in each sex ; the slightly 

 infuscate patch occupies about one-third of the length, and the 

 second antennal joint has no bristly hairs underneath, thus differing 

 from M. dcuatus. 



This species is found in the plains under tufts of the plant 

 Mesemhryanthemum edule, and not on wet moss on mountains or 

 mountain sides as M. dcustus and M. flavus, Thunb., or M. tabuloi.
