nonnihil attenuatus, deinde fere parallelus, sed ad basim leviter 

 sinuatus, basi apice latior, sinuatus, angulis posticis acutis, promi- 

 nulis, supra antice deflexus, a medio ad basim deplanatus, con- 

 fertim strigillatus ; elytra antice prothoracis baseos nonnihil latiora, 

 ovata, versus apicem acuininata, prothorace duplo longiora, in medio 

 vix quarto latiora, supra deplanata, postice longe dehiscentia, carinis 

 quatuor, secunda breviore, utrinque praedita ; sutura elevata, inter - 

 stitiis verrucis nonnullis indistinctis obsitis ; subtus brevissime 

 pubescens ; pedes rugosuli, pubescentes, $ tibiis intermediis vix 

 sinuatis. Long. 8 mm. ; lat. 4 mm. 



The facies of this and the following species, and also of M. 

 (Solenomerus) agilis, Per., is somewhat different from that of the 

 other South African species owing to their much smaller size and 

 more trapezoidal prothorax.

Allied to M. (Solenomerus) agilis, P6r., but the prothorax is more 

 trapezoidal, and the costae on the elytra are better denned, and 

 more carinate.
