Coleoptera from New Zealand. 163 
Thorax with four setigerous punctures on each side, the 
last ventral segment with one; scutellum more or less striate 
at base. 
When compared with its nearest ally, No. 1469, it will be 
seen that it is narrower, the thorax is longer and narrower 
and much less contracted near the base, and the elytral striz 
are not so deep. In P. pellax the grooves of the elytra are 
quite deep and rather broad. 
Female.—Thorax of equal length and breadth, appearing 
elongate, its sides very slightly curved; elytra with more 
feebly impressed strie; legs rather slender; last segment 
with two punctures near each side.

Ligar’s Bush, Papakura. 
Pterostichus obsoletus (No. 1469, var.). 
This is very much like P. hybrida. The shoulders are not 
dentiform, there being only a slight thickening of the margins 
there; the transverse line which marks off the base of the 
elytra from the striz in allied species is here quite obsolete ; 
the scutellum is only indistinctly striate; the elytra are 
narrowed towards the base. The thorax is only about one 
sixth broader than long, and its sides are only moderately 
curved; its anterior angles are rounded, the posterior are 
rectangular. The elytral strie are somewhat irregularly 
punctured, some of the punctures are much smaller than the 
others, so that the striz themselves appear interrupted in 
some parts.

Hunua Range. Two males. 
Pterostichus Sharpianus, sp. n. 
Oblong, very slightly convex, shining, black; femora 
piceous; the antenna, palpi, tibie, and tarsi pitchy red. 
Head much narrowed behind, the frontal impressions broad 
and shallow; labrum usually quite transverse. yes large 
and moderately prominent. Antenne rather slender, reaching 
the intermediate femora, their three basal joints glabrous, the 
fourth not longer than the third. Mandibles reddish, smooth. 
Thorax nearly one fourth broader than long; its sides regu- 
larly curved from the front angles to behind the middle, 
slightly but not sinuously narrowed behind, posterior angles 
rectangular, not at all projecting; the surface faintly striate 
transversely, the central furrow well-marked but sometimes 
indistinct near the apex; basal fovex elongate but not sulci-
