374 Snarp—On New Zealand Coleoptera. 
scarcely at all sinuate behind; the base a little rounded on each side, so that the 
hind angles would be quite obtuse except that they are a little prominent ex- 
ternally, finely punctate across the basal portion, with fine median channel, but 
without lateral impression. Elytra with the sutural strize rather deep, the external 
finer ; their punctuation of a rather peculiar nature, so that it is intermediate be- 
tween crenation and punctuation. 
This species has a very Trechoid appearance, and will be distinguished by its 
small, smooth eyes. Although I have seen only two females, I do not detect 
anything to distinguish it from this genus.

Tacuys. 
Tachys latipennis, n. sp.—Testaceus, plus minus ve picescens, nitidus, antennis 
palpis pedibusque testaceis ; prothorace cordato, angulis posterioribus rectis ; elytris 
striis duabus ad suturam sat profundis, striaque tertia minus distincta. Long. 
2-25 m.m. 
Antenne feeble, second joint elongate, longer than third. Eyes small, head 
bimpressed between them, the impressions rather widely separated. Thorax a 
little curved at the sides, narrowed and sinuate behind, the hind angles sharply 
defined, exactly rectangular. There is a rather fine channel along the middle, 
and a fovea at the base on each side. The elytra are broad and short, with the 
shoulders perfectly rounded. The sutural stria is deep, and extends to the apex. 
The second stria is also rather deep, but does not extend on to the apical portion ; 
and there is a third indistinct stria. The strize external to these are almost entirely 
obliterated. The apical plica is very distinct, and there are two obsolete seti- 
gerous punctures on the third interstice. The oblique truncation of the anterior 
tibia is excessively slight.

CILLENUM. 
Cillenum batesi, n. sp.—Oblongo-ellipticum, convexum, politum, pallido- 
testaceum, capitis vertice elytrorumque disco vix infuscatis ; thorace cordato, 
basi depresso, subplicato; elytris substriatis, margine laterali crassiusculo, inter- 
stitio tertio tripunctato. Long. 41 m.m. 
This is very closely allied to C. albescens, though easily distinguished by the 
almost complete absence of the dark variegation of the upper surface. The margin 
of the elytra also is less prominent at the extremity. 
Mr. Bates has discussed at some length the points of resemblance and contrast 
between the New Zealand and European Cillenum, deciding on considering them
