370 Snarp—On New Zealand Coleoptera. 
utrinque fovea elongata lineare, angulis posterioribus exacte rectis; elytris 
regulariter sat profunde striatis, striis fere impunctatis, interstitio tertio bi vel 
tripunctato. Long. 13 m.m. 
Antenne slender, with the fourth joint rather longer than the third. Head 
short, with prominent eyes, and with two fovez near the front. Thorax flat, 
about one-fourth broader than long, the sides a little narrowed, and slightly sin- 
uate behind; the central channel deep, extending from base to the front margin, 
half-way between it and the side with an elongate channel-like fovea. Elytra 
with slightly rounded shoulders, destitute of denticle, the striation regular and 
rather deep, with two or three large punctures placed on the third interstice touch- 
ing the third stria. The male has the hind femora simple, and one seta on each 
side of the last ventral segment. 
This is, no doubt, allied to Haptoderus maorinus Bates, which, however, is 
only 7 or 8 m.m. long, and is almost destitute of frontal impressions. Although 
no doubt the type of a distinct group, or sub-genus of New Zealand Pterostichi, 
I somewhat doubt the propriety of associating this insect with the European Hap- 
toderi, though no doubt the structural characters of the New Zealand and European 
species, so far as yet observed, are very similar. The labrum in the New Zealand 
insects is very short and broad, the mandibles short and stout, smooth, not striate 
above, the left one with slender and elongate incurved apex, the fourth joint of 
antenn longer than the third, the thorax with a front margin, two lateral setze, 
and the scutellum estriate. 
Dunedin and Otago. Sent by Professor Hutton in 1876 and 1877, two male examples. 
Pterostichus ovatellus Chaud.—(Scutello basi striato). Nigerrimus, femoribus 
piceis ; prothorace evidenter transverso, basi utrinque unifoveolato, angulis pos- 
terioribus subrotundatis ; elytris profunde fortiterque striatis, strus punctatis, 
interstio tertio bi vel tripunctato. Long. 17 m.m. 
This is a peculiar species, with thorax only three-fourths of its width in 
length ; a single deep fovea on each side the thorax, without any trace of external 
plication; only two lateral setae on the thorax. The elytral strize very deep, and 
with two or three punctures (placed variably and irregularly) on the third interstice, 
and the shoulder and basal margin of the elytra formed as in P. constrictellus and 
elongellus. It quite agrees with those two species in appearance, but departs 
greatly from them by the number of the thoracic sete, and by the interstitial 
punctures on the wing-case. The male has the front tarsi much dilated, the hind 
femora a little thickened in the middle, but not angular, and two punctures on 
each side of the hind margin of the last ventral segment. 
New Zealand; Castlenau. Chaudoir was not acquainted with the male, and I have not seen the 
female. Chaudoir’s examples, like my own, came from Castlenau, and I feel little doubt of the correct 
identification.
