10 COLEOPTERA 



20. M. alternans, Castelnau; Trans. Roy. Soc. Viet., vol. viii.,/. 161. 

 This insect is very nearly allied to M. impressum, and has the same 

 punctiform impressions of the elytra, but they are very different, being 

 disposed so as to leave alternately broad and narrow spaces between 

 them ; the broad spaces number four, having two punctated striae 

 between each ; the colour is rather darker than in imp res sum, and the 

 elytra rather broader and of a more oval form. 



Length, 1 1 J lines. 



This insect was brought from the neighbourhood of Otago, and is in 

 Dr. Howitt's collection. 



NOTE. The above species have all the same facies, being rather 

 depressed, with the thorax more or less cordiform ; the latter has a 

 longitudinal sulcate in the middle, and two transverse impressions one 

 in front and the other behind, with others at each angle. 



21. M. crenaticolle, Redtenbacher ; Reise d. Novara, Zool. Sub- 

 tus nigra, supra obscure cupreo-senea; thorace cordato, lateribus crenatis; 

 elytris intus serie-punctatis, extus irregulariter punctatis et variolosis.

22. M. Splnifer, n. s. Elongate, moderately convex, glossy, 

 bronzy-black, with the legs, palpi, and antennas a little reddened. Head 

 large, with two elongate, shallow, frontal depressions, longitudinally 

 rugose near the eyes, with fine transverse wrinkles in front, and trans- 

 versely impressed behind the eyes. Thorax cordate, its sides very 

 slightly rounded as far as the middle, from thence narrowed and 

 sinuated to the obtuse hind angles ; the dorsal furrow terminates in the 

 transverse frontal impression, and is deepest behind ; the basal foveae 

 are rather small and situated close to the angles, with a few shallow 

 punctures extending inwards ; the lateral rims are thick, and along the 

 marginal channel, there is a row of coarse punctures with bristles pro- 

 ceeding from them, and there are a few aciculate impressions on the 

 disc. The elytra are oviform, widest behind ; each has eight striae, the 

 outer far more deeply impressed than those near the suture, their punc- 

 tuation corresponding, id est, fine near the suture but coarse else- 

 where ; the interstices are flat on the middle, the outer convex, the 

 seventh bears two punctures near the base, and three behind in the 

 stria ; the space between the external stria and margin is smooth and 

 convex, with the channel beyond more or less punctate ; the sculpture 

 becomes much less obvious, and confused, towards the apex, and the 

 surface bears more or less distinct transverse, aciculate impressions. 

 Legs moderate ; the trochanter of the middle with a stout spine, directed 

 backwards.

I have one mutilated example of this fine species from Mr. Smith, of 

 Waitakerei, near Auckland.
