veloped. Prothorax(6 x 9 mm.) strongly transverse, apical margin 

 with rather large, flattened granules irregularly arranged in two 

 rows, basal margin with suialler, more rounded ones; median space 

 wide, convex in michlle, smooth; sublateral spaces strongly longitn- 

 dinally strigose; mesial row of tubercles with seven on eacli side, in 

 single series with a tendency to duplication near base and apex, the 

 individual tubercles transverse, depressed, flattened, the central 

 tubercle being the largest; with a lateral row of five tubercles or 

 dentations on each side, tubercles of same size and appearance as 

 tiie mesial row. in single series as viewed from above (l)ut not so 

 widely explanate as in M. draco) ; as viewed from the side, ar- 

 I'anged in a cluster; sides strongly granulate, size of granules 

 diminishing from above downwards. Elytra (17 x 9 mm.) elong- 

 ate, apical margin with a flange of small tubercles, emargination 

 feeble; disc subgranose between tubercles, suture with granules 

 subobsolete, confluent; flrst. row of tubercles from near base to 

 apex, consisting of four or five elongate, flattened tubercles, and 

 two or three larger conical ones on declivity : second row from base 

 to edge of declivity of about seven elongate tubercles, somewhat 

 larger than in first row, last one rounded, hardly conical; fourth 

 interstice with two elongate tubercles anterior to middle; third 

 row of five rounded, ^ubeonical ones extending from middle; 

 fourth row with about twelve, the first six. large, rounded, the 

 I'emaining ones becoming progressively smaller. Sides with rows 

 of somewhat flattened subcontiguous tubercles. Beneath subnitid, 

 a]iical segment with a narrow transverse impression. Prosternal 

 tubercles rather strong. Anteri(n' tibia? with a small group of 

 teeth one-third of the length from apex. Penis strongly emargi- 

 nate at apex, angles produced into subparallel horns. Dinienf^iovs: 

 (J, 27 X 9 mm.

A single male under examination, readily distinguished froni all 

 its congeners by the flattened appearance of both prothoracic and 

 elytral tubercles. It comes nearest to .V. //?.s/_r/>y/.s, ])ut the difference 

 in the tubercles is too great to allow of my considering it as a 

 variety of that species.
