22 COLEOPTERA 



longish bent groove on each side behind, fading away in front ; elytra 

 with the grooves very deep ; third and fourth, and fifth and sixth con- 

 nected at the end ; between the eighth and ninth a row of impressed 

 points ; tibiae and tarsi sHghtly ferruginous. 



Length, 6| hnes. 



Port Nicholson. 



Note. — As there will be difficulty in determining the species by the 

 above description, I add some remarks by Mr. Bates, who, no doubt, 

 examined the type in the British Museum. 



" A large shining black species (6| lines,) with large ovate thorax, 

 much larger in proportion to the elytra than in any other described 

 species. The hind angles of the thorax are very obtuse, almost 

 rounded ; and the lateral margins are widely explanated and strongly 

 reflexed, of the same width from the anterior to the posterior angle. 

 The elytra are ovate, rather rounded at the shoulders, and strongly 

 sinuate near the apex. The tarsi are grooved only on the sides." 



Mr, Lawson and I found several specimens at Auckland. 



46. A. montivagUS, n.s. This species is intermediate in 

 form between A. elcvatiis and A. polituhis, being less broad than the 

 latter, with a more oviform thorax, which however is decidedly less 

 oviform than that of A. elevatits ; it is of a shining pitchy-black colour, 

 the elytra faintly tinged with red, femora piceous, antennae, palpi, tibiae, 

 and tarsi reddish. Head rather short, very little elongated anteriorly, 

 with two frontal depressions, and faintly strigose ; labrum emarginate. 

 Thorax a little longer than broad, apex only slightly emarginate, sides 

 rounded, and obliquely narrowed posteriorly, with obtuse hind angles, 

 and widely explanated and reflexed side margins ; the disc is convex, 

 with a distinct dorsal furrow ; there is a broad curved line near each 

 side, the usual basal cavities, which are rather large and ill-defined, and 

 the surface is finely strigose. The elytra are broadly oval and sinuate- 

 angustate behind j each bears a short scutellar, seven rather wide dis- 

 coidal, and two marginal, strise, all of which are impunctate ; the inter- 

 stices are convex, the marginal with a row of large, rather transverse, 

 punctures, and the striae are more or less confluent towards the apex. 

 The tarsi are of the orthodox pattern, indistinctly grooved above, and 

 with somewhat spongy soles. 



Length, 5^ lines. 



I found this species near Whangarei Heads. 



47. A. politulUS, n.s. In this species the thorax is scarcely 

 longer than broad, with rounded sides, narrowed towards the base, and 

 indistinct, obtuse hind angles, and explanated and reflexed lateral 

 margins ; the marginal grooves are rather wide, there is a curved impres- 

 sion near each side, the dorsal furrow ends in broad depressions, the 

 basal region is rather uneven, with broad angular depressions, and the 

 disc is finely strigose ; the apex is emarginate. The elyti'a are broadly 

 ovate, with impunctate strise, and slightly convex interstices, and a 

 marginal row of large punctures. The head is rather elongate, with
