The elytra of this form are a little longer than in M. vmiszechi Thorns. ; the legs 

 of the male are moderately elongate; the tip of the hind femora extends only a little 

 beyond the apex of the abdomen. 



In colour of the pubescence and shape and colour of the band of the elytra it 

 reminds one very much of a species of Longiconis {Enmimefes haroldi Qued.) which 

 occiu-s in the same locality.

In one specimen the postmedian black patch of each elytron is much more 

 conspicuous than it is in others, as the rest of the elytra of this example is almost 

 uniformly pubescent grey.

The mate differs from M. inermis Thoms. especially in ha\ ing the presternum 

 granular, the first joint of the antennae shorter, and the third to seventh er eighth
