 posterior tibiae black, with a long apical pale ochraceous annu- 

 lation ; rostrum pale ochraceous, its apex black ; head deeply 

 longitudinally sulcate between the eyes, which are contiguous to 

 the anterior margin of the pronotum ; antennae much longer than 

 the body, basal joint almost as long as the head and pronotum to- 

 gether ; pronotum very coarsely punctate, anterior collar distinct, 

 transversely constricted at about one-third from anterior margin, 

 in front of which are two distinct callosities with a short central

 concolorous, membrane reflecting the dark abdomen beneath ; head 

 beneath and sternum pale ochraceous, abdomen beneath more or

This species is allied to M. antranii by the concolorous cuneus, 

 but differs from it in the different colour of the pronotum and 

 scutellum, the absence of the short carinate line between the pro- 

 notal callosities, &c.
