2323. M. rugipenne, n.s. Pitchy-black, shining ; legs and 

 antennae pitchy-red. 



This, no doubt, is nearly related to M. monilifer, but the head 

 is more or less uneven and wrinkled. The eyes are prominent. 

 The mandibles are elongate, and are marked with wrinkles and 

 punctures. The antenncz reach the middle of the thorax, the second 

 and third joints are evidently longer than the following ones, and 

 the fine pubescence is almost entirely conAied to the four terminal 

 joints, being scanty even there. The thorax is about one-fifth 

 broader than long, is widest near the front, though only very little 

 narrowed for about two-thirds of its length, beyond which the pos- 

 terior contraction is generally rather abrupt ; the basal angles are 

 thick ; the margins are explanate and somewhat rugose, with six or 

 seven setigerous punctures along each side ; the dorsal furrow 

 becomes obsolete near the base and apex, the latter is more feebly 

 incurved than the former ; the basal fossae are large, and the sur- 

 face generally is finely wrinkled. The elytra are slightly narrowed 

 towards the shoulders, the striae are tolerably deep and regular, 

 they touch the base, but become confused or rugose near the apices, 

 the punctures in the grooves are much coarser near the sides than 

 they are near the suture ; the interstices are rugose, so much so in 

 some examples that the punctures in the striae are less apparent 

 than the interstitial rugosities. The external apical prolongation of 

 the anterior tibia is thick and oblique, that of the intermediate pair 

 is well developed, the posterior pair are only slightly produced. The 

 last segment of the abdomen is transversely wrinkled, and has four 

 setigerous punctures. There are two oblique and one median de- 

 pressions on the prosternal process. Underside glossy. 



M . tersatum is another nearly-allied species ; it has, however, 

 only four hispid punctures on the labrum, instead of six as in this 

 species. 



? . Length, 8 ; breadth, 2f lines. 



Ashburton, Canterbury. Mr. W. W. Smith has been kind enough 

 to send me three examples which he found under cakes of dry 

 manure near the side of the river.
