Oblong-oval, rather convex, Llack and shining; the heac] 

 is smooth, with the frontal stria complete and nearly straight 

 anteriorly and somewhat lightly impressed ; the thorax is 

 slightly ciliate on the lateral edges, the two lateral strife are 

 parallel to each other and well marked, the inner stria con- 

 tinues, and is rather fine, behind the head; the elytra, striae, 

 inner humeral apical and dimidiate, 1-3 complete and strong, 

 with the edges feebly crenulate, 4 short, apical, and almost 

 obsolete, sutural fine, shortened apically, and scarcely reaches 

 the middle; the pygidia are densely punctured ; the presternum 

 has two striffi between the coxas, which widen out behind, but 

 do not reach the base, and apparently join base anteriorly ; 

 the mesosternum is emarginate and the stria is complete and 

 rather fine, and it does not follow the outline of the emargina- 

 tion ; the anterior tibia are strongly 3-dentate. 



In outline this species agrees with M. intrepidus, Lew., 

 but the dense punctuation of the pygidia and the prosternal 

 stria are good distinguishing characters.

Breviter ovatus, convexiusculus, niger, nitidus ; stria frontali 

 Integra antice subrecta ; pronoto stria lateral! externa brevi, 

 interna Integra ; elytris striis validis, 1-3 dorsalibus integris, 

 humerali interna dimidiata, caeteris nullis ; propygidio pygidioque

L. 8 miU. 



Shortly oval, somewhat convex, black and shining ; the 

 head impunctate and very feebly impressed on its vertex, 

 stria complete and strong, almost straight in front ; the 

 thorax smooth, outer lateral stria is short and confined to the 

 anterior angle, inner complete, somewhat deep and a little 

 sinuous, continued and somewhat crenulate behind the head ; 

 the elytra, inner humeral stria strong, apical, and dimidiate, 

 1-3 dorsal similarly strong but complete, 4 is represented by 

 an apical puncture, all the strise have crenulate edges ; the 

 propygidium and pygidium are moderately punctured ; the 

 prosternum is smooth ; the mesosternum is emarginate in 

 the middle, with a rather fine marginal stria; the anterior 

 tibia are strongly 3-dentate. 



This species is considerably larger than H. sikorce, Lew., 

 also from Madagascar
