 separated; femora stout: tibise granulate, the front pair rather 

 strongly denticulate on lower surface. Length, 5h nun.

In the latest talkie of the genus,* would be associated with 

 M. granulatus and M.faligiiieus, but readily distinguished from 

 these by the abdomen. In general appearance, it is something 

 Mke JJ. piliventris, M. caviventris, and some specimens of M. 

 ventralis, but with the abdomen carinate: the only other de- 

 scribed species having the abdomen ti-ansversely bicarinate is 

 il/. bicarinatus, but, on that species, the carina on the first .seg- 

 ment is much more distinct than on the second, the front coxje 

 are much closer together, and the size is very much less. The 

 excavation on the undersurface is very conspicuous, but less so 

 than on M. fovedtus. On the prothorax, there is a depressed 

 seta on each granule; on the elytra, the sette are in single rows 

 on the interstices, but the four lateral ones, except at the tip, 

 are non-setose. A few inconspicuous gi-anules are present on 

 the elytra.

UrACANTHUS GLABRILINEATUS, n.Sp. 



(J. Dark piceous-brown, becoming black in places; elytra with 

 apical two-thirds light castaneous. Densely but somewhat 

 irregularly clothed with stramineous pubescence, very dense 

 along undersurface of middle femora. 



Head with median line deep and narrow, base rather densely 

 punctate. Antennte almost extending to tip of elytra, fourth 

 to tenth joints dilated on one side of apex, eleventh about one- 

 third longer than tenth, slightly notched on lower side near 

 apex. I'rothorax much longer than wide, base about one-fourth 

 wider than apex, sides bisinuate: transversely corrugate through- 

 out, and with two small nodes in middle. Elytra moderately 

 narrowed from shoulders to basal third, thence parallel-sided 

 almost to apex, each strongly emarginate and acutely bispinose
