OF NEW ZEALAND. 819 



1454. M. obtusum, n.s. Black, not very glossy, legs piceous ; 

 the tarsi and three basal articulations of the antennae dark-red, the 

 remaining joints ferruginous ; palpi rufescent, paler apically ; body 

 elongate, medially contracted, somewhat convex, with a few scattered 

 hairs. 



Head constricted and punctured behind the eyes, not quite smooth, 

 with one or more curved impressions near each eye ; the base of 

 each jaw with a fovea-like depression encroaching on the edge of the 

 epistome ; eyes prominent. Prothorax about as long as broad, its 

 margins entire, regularly but not strongly rounded laterally, pos- 

 terior angles obtuse ; basal fossae deep and narrow, dorsal groove 

 abbreviated ; the surface has a few fine striolae, most obvious on the 

 middle ; the front is more or less punctated, as is also the space 

 between the basal foveae. Elytra rather broadly oval, punctate- 

 striate, the eighth striae obsolete, the spaces beyond almost smooth, 

 having only about six punctures on each. Underside black, tro- 

 chanters rufous; head smooth, prosternum nearly so, mesoternum 

 punctated. 



The form of the thorax is peculiar, not cordate, almost quadrate, 

 its sides regularly rounded, with a slight notch behind to indicate the 

 position of the angles, which otherwise might be said to be obtusely 

 rounded or even obsolete. The outer apex of the intermediate tibiae 

 not at all produced, posterior smooth. Its nearest ally, so far as 

 can be determined at present, seems to be M. dyschirioides. 



Length, 5^-6 lines ; breadth, if-2. 



I have seen four individuals, all taken by Mr. S. W. Fulton on 

 Mount Maungatua, Otago.

 Anchomenus (p- 20). 



1455- A. lucifugUS, "•••>^ Broad, sub-oblong, sub-depressed; 

 head and thorax shining black, hind-body smoky-black, legs rufo- 

 piceous ; three first articulations of the antennro piceo-rufous, the 

 remaining joints, as well as the tarsi and palpi, ferruginous. 



Head oviform, slightly constricted behind the eyes, and, except 

 the frontal foveae, quite smooth ; eyes conspicuous ; mandibles mode- 

 rately elongate, rufescent ; labrum nearly square, a httle, but widely, 

 incurved. Prothorax about as long as Ijroad, apex slightly arched, 

 base truncate, sides strongly and regularly rounded, gradually nar- 

 rowed behind, posterior angles obtusely rounded ; the median groove 

 extends beyond the angulated frontal impression, and seems uncom- 

 monly broad; the depressed space near each hind angle is large, and 

 from each proceeds a curved impression inside the marginal channel ; 

 lateral margins explanated and reflexed, disc with many transverse 

 undulating striae. Scutcllum small. Elytra not greatly exceeding the 

 thorax in breadth, but twice its length, widest before the middle, 

 shoulders rounded, sides with reflexed rims and not much curved, 

 rather abruptly sinuate-angustate behind, apices somewhat produced 

 and, individually, olDliquely emarginated at the extremity ; each with 

 eight almost crenate-punctate striae besides the lateral groove ; inter-
