OF NEW ZEALAND. 1409 



2455. H. mandibulare, n.s. Elongate, narrow, shining; 

 the head, mandibles, and thorax red ; elytra darker, infuscate-red ; 

 legs testaceous ; labrum, antennae, and palpi fulvescent ; pubescence 

 yellowish, most conspicuous on the hind-body. 



Head with about six moderately large punctures on the frontal 

 half, the other parts (except the smooth central portion) with 

 numerous finer punctures. Thorax much longer than broad, slightly 

 narrowed towards the base; there is a row of distinct punctures 

 along each side of the middle, some irregular ones near the sides, 

 and interposed between the larger punctures there are some minute 

 dots. Elytra relatively small, but rather longer than broad, with 

 rounded shoulders, their extremity incurved ; their punctures are 

 moderately large, rather shallow, and somewhat serial. Hind-body 

 finely sculptured, the lateral margins of the fifth segment become 

 quite narrow behind, styles moderate. 



Smaller than H. dispersum, Fauvel, differently coloured ; the 

 mandibles with two basal denticles on each, and a large acute tooth 

 between these and the middle ; the head, instead of being widest 

 behind, as it is in H. dispersum, is narrowed there, it is longer, the 

 shape being oblong, and the sculpture differs ; the apical spines of 

 the posterior tibia are longer, and the tarsi are more elongate and 

 slender ; the basal joints of the front tarsi are simple and of nearly 

 equal width. 



. Length, 2-f lines ; breadth, nearly J line. 



Paparoa, near Howick. Unique. 



2456. H. duplicatum, n.s. Shining, red ; legs, antennae, and 

 palpi yellowish-red, tarsi yellow ; pubescence greyish-yellow. 



Eesembles H. mandibulare. T^e head more oblong, scarcely at 

 all narrowed behind, with minute punctures interposed between the 

 larger ones. The thorax is slightly longer, not distinctly narrowed 

 posteriorly, its front and hind angles (as is the case in the preced- 

 ing two species) are rounded, it is attached to the head by a short 

 but obvious neck, and the discoidal series of punctures are more or 

 less duplicated. The last two dorsal segments, though rather darker, 

 are nearly testaceous at the extremity ; the fifth is acutely rounded 

 at the apex, and the styles project beyond it at the sides. Eyes 

 smaller. 



Male. Anterior tarsi moderately dilated ; the fifth segment, 

 underneath, with a deep notch extending two-thirds of its length. 



Female. Fifth segment subtruncate behind. 



Length, 3-3 J lines ; breadth, nearly J line. 



Maketu, Hunua Eange. One pair only. All the species occur 

 on the ground, amongst fallen leaves, and are evidently very rare. 



Group OXYTELID^l. 



CoprostygnuS (Gen., p. 1027, Part V.). 



2457. C. OptanduS, n.s. Elongate, glabrous, glossy, pitchy- 

 black ; the palpi, tarsi, and basal joint of antennae red ; legs rufo- 

 piceous.
