82O COLEOPTERA 



stices a little raised, impunctate. Legs rather stout; anterior tarsi 

 simple, their first joint oblong and narrowed behind, the next two 

 decrease and have rounded hind angles ; fourth cordate ; the three . 

 basal joints of the other pairs grooved at the sides. 



The above characters will enable it to be easily recognized ; all 

 the New Zealand and foreign species I have seen are dissimilar. 



$ . Length, 8J lines ; breadth, nearly 3 lines. 



I took my specimen from under the bark of a large kauri log near 

 the Waitakerei Bail way- station. 



OBS. No. 42 is not a Calathus; it must be placed at the head of 

 the Anchomenii, so as to become A. deformipes. The front tarsi of 

 the male are narrow, but of the orthodox pattern : the description of 

 the feet at p. 19, " Man. N.Z. Col.," applies to the female. 



Tropopterus (p. 27). 



1456. T. oxygonus, n.s. Convex, ovate-oblong, somewhat 

 contracted medially ; shining, brownish-black, the sides of the thorax 

 and elytra and the femora testaceous, antennae and tibiae testaceous- 

 red, tarsi and palpi fulvescent, mandibles dark-rufous. 



Head smooth behind, the inner grooves rather broad and shallow, 

 the spaces between them and the sharply-defined ocular grooves 

 broad and rather flat ; labrum rufescent and slightly emarginated ; 

 eyes large, but not convex. Prothorax sub-quadrate, transversal, 

 base and apex nearly truncate, anterior angles almost acute but not 

 protuberant, the sides well rounded, moderately sinuate-angustate 

 behind, the posterior angles rectangular and just perceptibly project- 

 ing ; disc impunctate, but with several aciculate marks, dorsal groove 

 not attaining the apex, basal foveee narrow, almost sulciform. Elytra 

 broader than thorax and twice its length, humeral angles rounded, 

 sides regularly but not strongly curved, their margins distinct and 

 explanate ; each bears eight rather distantly and finely punctured 

 striae (besides the marginal), but becoming deeper posteriorly; inter- 

 stices plane, the seventh a little elevated behind and curvedly pro- 

 longed to the apex. 



The first three antennal joints are nude ; the terminal joint of the 

 labial palpi is almost as acuminate as the maxillary. The sutural 

 striae of the elytra are not recurved behind. The insect is less con- 

 vex and more oblong than No. 61. 



? . Length, 2f lines ; breadth, nearly i J. 



Mr. S. W. Fulton sent me one individual which he caught on 

 Mount Maungatua, Otago.

 Trichosternus (p. 3 1 )- 



1457. T. OpulentUS, n.s. Sub-oblong, moderately convex; 

 shining ; tibiae, tarsi, and palpi red, femora blackish, antennae 

 pitchy-red with the pubescent joints paler; head black, some- 

 what rufescent ; thorax black tinged with brilliant green, red, 

 and yellow, the aureate tints chiefly confined -to the margins ancj
