Castaneo-rufous, shining, antennpo slender, club pale fuscous. 



Rostrum subcylindric, slightly narrowed behind, finely punctate and 

 shining. Interocular fovea very distinct. Apex of thorax shining, but 

 finely punctured, disc not flattened, with a small basal impression. Elytra 

 very slightly rounded, unimpressed, rather broad.

Tairua. Unique. 



M. remotus, Sharp. 914. Man. N.Z. Coleopt., p. 513. 



Rufo-piceous, club nigrescent. 



Thorax medially impressed near the base. Interocular fovea indistinct. 



(^ . Length, I| fines; breadth, quite j line. 



Tairua. One pair. 



M. frontaUs, Broun. Ann. Mag. Nat. Hist., November, 1893. 



Shining, rostrum and thorax rufous, elytra and legs rufo - castaneous, 

 club dull black. 



Thorax shining and only feebly constricted in front. Literocular fovea 

 indistinct. Elytra indefinitely impressed before the middle. 



? . Length, 1| lines ; breadth, nearly | line. 



Hunua Range. One. 



M. badius, Broun. 920. Man. N.Z. Coleopt., p. 516. 



Broad, testaceous or slightly infuscate. 



Thorax short and broad, unimpressed, abruptly narrowed in front. 



3 . Length, \\ lines ; breadth, nearly f line. 



Whangarei. One pair. 



M. crenatus, sp. nov. 



Subdepressed, moderately nitid, rufo-piceous, the frontal half of rostrum 

 and the humeral area rufescent, antennae clear red and shining, club nigrescent 

 and densely pubescent. 



Rostrum evidently narrowed behind the point of antennal insertion, 

 before the middle, broadly sulcate from thence to the back of the eyes, 

 distinctly yet finely punctate, more finely and distantly in front ; occiput 

 nearly smooth and shining. Thorax hardly longer than broad, considerably 

 narrowed and constricted in front, widest behind the middle, strongly curvate 

 there, the basal margin minutely prominent at the sides ; disc flat, with a 

 more or less evident smooth median line reaching the constriction but distant 

 from the base, its punctuation moderately fine and close. Elytra rather 

 wider than thorax at the base, very gradually narrowed posteriorly, 

 moderately crenate-striate, interstices with fine serial punctures, and some- 

 what rugose. Legs closely punctured, 3rd tarsal joint a little expanded 

 but not lobate. Pubescence scanty, greyish, visible only on the posterior 

 part of the elytra. 



Female. — Rostrum more slender, shining, finely and sparingly punctured, 

 distinctly narrowed behind the middle. 



The rostral canal and crenate-punctate elytral striae will enable this species 

 to ))e recognised. 1308 and 914 most nearly resemble it.

Hunua Range and Woodhill. One at each.
