 "Auckland." 



A large species (9| lines), of which I have seen no specimens from New 

 Zealand. The description and figure agree pretty well with a Chinese species, 

 and there may be an error in the locality. 



Dicrochile subopaca, n. sp. 

 D. oblongo-ovata, subdepressa, nigra, palpis et tarsis rufo-piceis ; elytris 

 alutaceis, subopacis ; capite parvo ; thorace quadrato, postice modice angustato. 

 Long. 4| — 5 lin. 



Shorter in form than the common Australian D. goryi, and the elytra 

 more ovate ; distinguished also by the alutaceous and subopaque surface of the 

 elytra. The head is relatively small, as in D. goryi. The thorax is quadrate, 

 moderately narrowed behind, with explanated and reflexed margins ; the hind 

 angles obtuse and rounded at the tip, the middle of the base broadly sinuated. 

 The elytra are elliptical-ovate, obliquely and strongly sinuate near the tip, 

 with the suture produced ; the lateral margins are somewhat explanated and 

 reflexed, the striae sharply impressed, the interstices scarcely convex. 



Apparently abundant near Christchurch. 



Dicrochile aterriina, n. sp. 



D. oblonga, nigra, nitida; capite majore ; thorace breviore, trans verso, 

 quadrato, postice paulo angustato, angulis posticis obtusis, apice rotundatis, 

 margine vix reflexo } elytris oblongis, nitidis, for titer punctulato-striatis, 

 interstitiis alternis magis elevatis. Long. 5 lin. 



Same size as D. subopaca, but distinguished at once by its deeper black 

 colour and shining surface, by its larger head (owing chiefly to the much 

 more prominent eyes), and much shorter, more transverse thorax. The palpi 

 and tarsi are also shining black. The elytra are much less sinuate truncate, 

 and the sutural apex less produced ; the strife are punctulate, and the inter- 

 stices more convex, especially the third, fifth, and seventh. 



Taken by Mr. C. M. Wakefield in some numbers at Lake Coleridge, under 

 stones in a dry lagoon.
