DASCII.LII'AK. 107 



fore, are obsplete; its surface is destitute of perceptible sculpture. 

 Scutellum large. Elytra oblong, incurved at the base, very slightly and 

 gradually dilated posteriorly, so that their sides are nearly straight; 

 they are feebly impressed before the middle, but the sculpture is so fine 

 and ill defined that it cannot be accurately described. 



Antennae moderately elongate, their 1st joint short and tliick, the 

 next oblong, 3rd more .slender and shorter than tlie elongate but 

 nioderately stout 4th, joints 5-10 finely and densely pubescent, each 

 rather longer than broad and nearly similar to one another, the terminal 

 rather longer than its predecessor. 



Underside subopacjue, fuscous, very finely and closely sculptured, 

 and bearing fine greyish pubescence. 



The almost uniform coloration and evenly pubescent surface, as well 

 as that underneath, ally it to M. pallidus, 2024, which, however, is 

 easily separable by its oval contour and distinct thoracic liind angles. 



Lengtli, 4^ mm. ; breadth, fully lA^iiim. 



Hump Ridge, Okaka. Found at an elevation of 3,500 ft. by Mr. A. 

 Philpott, who sent me a pair of specimens. 



3422. Mesocyphon longicornis sp. nov. 



Subdepressed, oblong-oval, subopaque; thickly covered with de- 

 cumbent greyish-yellow jiubtscence ; castancous, Iri^s ami antennae 

 paler. 



Head narrower than the thorax, prolonged, and truncate in front of 

 the antennae, with rather indistinct fine granular sculpture. Thorax 

 twice as broad as long, subtruucate in front, with obtuse angles there, 

 its sides nearly straight, base bisinuate, with rectangular angles, the 

 surface minutely granulate. Scutellum large. Elytra with rounded 

 shoulders, so that the base seems to be but little wider than the thorax; 

 they become broader behind the middle, and are of the usual length; 

 they are somewhat flattened or longitudinally impressed along the basal 

 half; there is an oblicjue, but not conspicuous, dark mark on each elytron 

 from the hind thigh towards the suture, which beais finer ashy pube- 

 scence; their ill-defined sculpture is obscured by the vestiture. 



Antennae elongate, filiform but not very slender, basal joint thick 

 and a little longer than broad, the slender 3rd not twice the length of 

 the 2nd, 4th slightly longer than adjacent ones, joints 3 to 11 unusually 

 elongate, each nearly thrice as long as broad. 



Underside finely pubescent, the abdomen irregularly maculate with 

 blown. 



There need be no difficulty in identifying this species, the antennal 

 structure of itself being distinctive. 



Length, 6 mm.; breadth, 2| mm. 



Otira Gorge; January, 1911. Two examples from Mr. H. W. 

 Simmonds, of Wellington. 



3423. Cyphon deterius sp. nov. Ci/phon Paykull, Man. N.Z. Coleopt., 



p. 318. 

 Oblong-oval, rather narrow, slightly convex, nitid; pubescence 

 slender, yellowish-grey, evenly distributed on the elytra; the head, a 

 broad median space near the base of the elytra, and the thoracic disc 

 fuscous; the rest of the elytra fusco-testaceous; the sides and basal 

 margin of the thorax obscurely rufescent; the tibiae and basal five 

 joints of the antennae testaceous; remaining joints of the latter, and 

 the femora, infuscate.
