tatis, utrisque seriebus duabus tuberculorum acutorum instructis. 

 Long. 12, lat. ad med. elytrorum 4 mm. 



Hah. Aden {Yerhurij). 



Almost entirely covered with greyish-white scales. Clypeus 

 prolonged below in a slightly curved and pointed process, the 

 edges of which are raised, so that its surface is concave in 

 front. Prothorax furnished on each side with a prominent 

 tubercle giving off two spiniform processes, the posterior of 

 which is curved backwards ; disk of the thorax slightly 

 raised in the middle, and furnished at the middle of its ante- 

 rior margin with two rather small, closely approximated, and 

 almost vertically raised tubercles. Elytra elongate-ovate in 

 outline, rather strongly and closely punctured ; each furnished 

 with two rows of sharp spiniform tubercles — one row marking 

 the boundary between the deflexed side and the slightly con- 

 vex disk, the other midway between this and the suture.

Hah. Aden and Lahej {Yerhury). 



This species seems to be most nearly allied to M. tentyri- 

 oides^ Pasc, which it resembles much in shape. It is quite 

 glossy on the thorax and elytra ; the latter are strongly but 

 not thickly punctured, and each bears three narrow longitu- 

 dinal costee, of which the outer one is less distinct than the 

 other two. The anterior tibiasof the male are thickened, and 

 in their distal three fourths bear a groove underneath, which 

 is lined with a longish grey-tawny pubescence ; the tarsi are 

 not dilated and are clothed underneath with rather long 

 tawny hairs instead of the pad of short hairs met with in 

 many species of the genus.
