Coleoptera from New Zealand. 303 



with fine punctures ; it is nearly smooth behind ; the lateral 

 rug£e, as well as those in front, are neither numerous nor deep • 

 on the forehead there are six deep longitudinal strise, near 

 each eye there is a puncture with four or five seta3. Lahrum 

 smooth, broadly rounded in front, with six setigerous punc- 

 tures. Eyes distant from thorax, rather small, very promi- 

 nent, the gense swollen below them. Mandibles elongate 

 wrinkled. Antennce stout, the basal four joints nude, the 

 others pubescent. Thorax slightly broader than long (7x6 

 millira.), widest near the front, very gradually narrowed 

 backwards, a good deal but not abruptly narrowed near the 

 base, the posterior angles obtusely rectangular, apex slightly 

 and widely incurved, base subtruncate ; the lateral margins 

 are entire, somewhat dilated and rounded in front, with eight 

 or ten setigerous punctures along each ; basal fossae not laro-e 

 close to the sides but not reaching the base ; there is a slight 

 impression between them, the central groove hardly extends 

 beyond the frontal curvate impression, the short longitudinal 

 stride near the front and base are scarcely discernible, and the 

 transverse striolse on the disk are rather fine and do not reach 

 the sides. Elytra elongate, a little narrowed towards the 

 shoulders ; they are punctate-striate, the punctures are rather 

 close and moderately fine throughout ; the seventh and ninth 

 interstices are slightly elevated, the former have about four 

 punctures; the sculpture of the lateral channels is shallow 

 and indefinite, but several irregularly-placed punctures are 

 visible ; there are two large punctures behind the scutellum, 

 the base itself is rather depressed and smooth ; there are very 

 few setae behind. Legs elongate; front tibice simple, the 

 middle pair somewhat angulate at the outer extremity. 



Underside shining black, nearly smooth. Head with six 

 setigerous punctures in a transverse series on the raised part 

 behind the mentum. Last ventral segment with one punc- 

 ture near each side. 



In M. simplex, Castelnau, the outer striffi of the elytra have 

 large square punctures ; there are several other difiereuces, 

 but, on the whole, it is the nearest ally.
