OF NEW ZEALAND. 737 



ate, basal joint ob.conical, largest ; second slightly longer than third ; 

 club oblong-oval, densely pubescent, as long as the funiculus. Prothorax 

 sub-triangular-ovate, considerably narrowed in front, rounded laterally. 

 Scutellum distinct. Elytra sub-parallel, more or less depressed. Legs 

 stout, moderately long ; tarsi stout, apical joint as long as the first three, 

 third more or less bilobed. Under-side plane ; mesosternum not abbre- 

 viated, metasternum moderate ; the two basal segments of the abdomen as 

 long as the metasternum, the suture between them indistinct or fine ; the 

 next two short, with deep sutures. COXCB small, nearly equidistant, the 

 anterior rather less separated than the others, yet far apart. Metasternum 

 finely grooved ; basal segments of abdomen broadly impressed. 



The primary character of the genus is the elongate antennal club, 

 equalling the funiculus in length. 



1308. M. laticollis, n.s. Shining, very finely clad, piceo-rufous, 

 antennal club blackish ; robust, sub-depressed, not parallel. 



Rostrum stout, nearly as broad as the head in front, narrowed behind 

 the middle ; finely punctured, the punctuation coarser behind, terminating 

 abruptly in line with the hind margin of the eyes, indistinctly impressed 

 along the middle ; the head with an inter-ocular punctiform impression. 

 Prothorax not very much longer than broad, rather abruptly narrowed 

 in front, a good deal rounded laterally; the anterior constriction con- 

 tinuous, causing the front to appear curvedly depressed ; there is a more 

 or less distinct dorsal impression most obvious near the base, and its 

 punctuation is moderately close but not coarse. Elytra truncate, or 

 nearly so, at the base, just appreciably narrowed anteriorly, appearing 

 broadest in line with the posterior femora, apex rounded, slightly 

 depressed transversely before the middle, rather fiat ; distinctly punctate- 

 striate, interstices rather broad, with a row of minute punctures on each ; 

 the sutural striae are most deeply impressed behind, the third and outmost 

 unite in a broad apical groove. Legs robust, the tibial hook well 

 developed. The clothing consists of very fine short greyish hairs. The 

 antennce are placed just before the middle of the beak.

Habitat, Parua. 



OBS. Dr. Sharp's Pentarthrum remotum belongs to this genus ; so do 

 Nos. 915 and 920. 



1309. M. rilSSUluS, n.s. Sub-depressed, rather narrow, glossy, 

 chestnut-red; tarsi and antennae yellowish, club obscure-red; sparsely 

 clothed with minute grey hairs. 



Rostrum moderate, shining, finely punctate. Head more distinctly 

 punctured, with a small fovea on its vertex. Prothorax constricted in 

 front, its broad part rounded laterally, impressed near the base, 

 moderately punctured. Elytra transversely depressed near the base, 

 punctate-striate, interstices punctulated. Somewhat resembling the female 

 M. remotum.
