190 COLKOl'TEHA 



giauulute. Elytra four times tlic length of the thorax, not double its 

 width, with rounded, slightly rufescent shoulders; their sculpture rather 

 fine and indistinct, appearing punctate on some parts and granulate 

 on others; near the suture, before the middle, there is a pair of sub- 

 rotundate but not very deep foveae; the lighter pubescence, though 

 unevenly distributed, does not form spots. 



Antennae longer than the head and thorax, basal joint thick, the next 

 almost oblong-oval, shorter but stouter than the elongate 3i'd, the 4th 

 still longer and stouter, joints 5-10 differ but little, eacli rather longer 

 ihan broad, the terminal elongate-oval. 



Underside nitid, fuscous, finely 2:)unctate and pubescent. 



When placed alongside M. tristis, 3073, this species is seen to be 

 smaller, more slender, and less oviform, its surface is more nitid; the 

 thorax is smaller, not in the least explanate or flattened at the sides, 

 which are more finely margined and rounded; the elytral foveae form 

 another distinctive character. 



Lengtli, i^ mm. ; breadth, quite 1^ mm. 



Hump Ridge, Southland. Two individuals found I:»y Mr. A. Philpott 

 in February, 1912. 



3565. Mesocyphon lateralis sp. nov. 



Elongate, subovate, slightly nitid; fuscous, legs and antennae 

 cf.staneous, mandibles and labrum rufescent; covered with slender, de- 

 pressed, dark-ashy, and I'ather thicker, less decumbent, yellowish-grey 

 setae, these latter irregularly distributed and patchy. 



Head moderately closely and finely granulate, the vertex with a more 

 or less distinct depression. Thorax a third broader than long, Avidely 

 bisinuate at the base, its sides almost straight, distinctly flattened but 

 not broadly so, and finely margined, with obtusely rectangular angles; 

 its surface ]ather closely granulate, not at all coarsely, yet moi-e dis- 

 tinctly than the head, and with an abbreviated linear impression along 

 the middle. Scutellum large, not distinctly granulate. Elytra four 

 times the length of the thorax, rather broader than it is at the base, 

 gradually widened to beyond the hind thighs, their shouldei's rounded; 

 along the suture, near the base, there is a depression which is obliquely 

 expanded before the middle; their sculpture is indefinite, on some parts 

 appearing closely but finely rugose-punctate, but nowhere discernibly 

 granular. 



Antennae elongate, with dark pubescence; vai'iable in colour, tlie 

 l)ase of the intermediate joints sometimes obscurely testaeeous; 2nd 

 oblong but evidently shorter than the more slendei- 3rd, the next the 

 longest, joints 7-1 1 elongate and rather narrower than the preceding 

 ones. 



Closely related to the North Island .1/. tn'.'<fis, .'5073, but less opaque, 

 with the sides of the thorax fiattened, and tlie elytra without any per- 

 ceptible granulation. 



Length, 5 mm. ; breadth, 2 mm. 



Mount Hutt, near Methven. Found by Mi-. T. Hall on the 30th 

 March, 1912, at a height of 3,500 ft. Apparently rare. 



3566. Mesocyphon halli sp. nov. 



Oblong-oval, subdepressed, nitid, variegate; rufo-castaneous, head 

 and thorax slightly infuscate, the posterior half of the elytra fuscous 

 but witli the suture there, and the apical margin obscurely fulvescent,
