OF NEW ZEALAND. 1 7 



apice rotundatis, margtne vix reflexo ; elytris oblongis, nitidis, fortiter 

 punctulato-striatis, interstitiis alternis magis elevatis. 



Long., 5 Jin. 



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 striae are 

 punctulate, and the interstices 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. 



NOTE. This species also occurs at Auckland, where I found a few 

 specimens some four or five years ago. 



38. D. OVicollis, Mots.; Bull Soc. Imp. Nat. Mosc., xxxvii.. ii., 

 316. Statura Platyni scrobiculati, sed elytris angustioribus, thorace 

 latiore ; oblonga, sub-depressa, nitida, nigra, palpis, antennis, tibiis tar- 

 sisque plus minusve ferrugineis ; thorace capite fere duplo longiore, 

 ovali, sub-convexo, reflexo, postice arcuatim angustato, medio canalicu- 

 lato, basi truncato, angulis posticis obtusis, anticis rectis apice rotun- 

 datis ; elytris thorace dimidio latioribus, subellipticis paulo opacis, 

 profunde striatis, interstitiis convexis, sutura elevatiore ; humeris mar- 

 ginatis, rotundatis, apice utrinque sinuato, medio prominulo. 



Long., 5 lin. ; lat. elyt, 2 lin. 



Nouvelle Zelande. 



NOTE. Mr H. W. Bates remarks : " By its elytra paulo opacis ; 



this may possibly be our D. subopaca ; but the description of the 



thorax cannot possibly be intended for that species (' capite fere duplo 



latiore, ovali.') There is not the faintest approach to the oval form in 

 the thorax of D. subopaca" 



39. D. limbata, n.s. The head is very similar in form to that 

 of D. subopaca, but is rather concave in front ; it is quite smooth, with ' 

 the exception of one or two punctures near the eyes, and is piceous. 

 Thorax transverse, with the sides rounded in front of the middle, and a 

 little narrowed behind, with distinct, but not acute, hind angles ; it 

 bears a very indistinct dorsal line, is depressed near the posterior angles, 

 and faintly strigose ; its colour is a brownish-black, the lateral margins 

 being testaceous. Elytra oblong, a little narrowed and rounded in 

 front, and obliquely and obtusely rounded, but not sinuated apically ; 

 they are a little convex, and sharply but finely striated, the external 

 striae being more or less confluent behind ; the only visible punctation 

 consists of two punctures on the third interstice, and a marginal row ; 

 the interstices, owing to the narrow striae, are rather broad ; the disc is 

 of a somewhat shining bronzy brown colour, the side margins testaceous. 

 Legs dull fuscous, antennae and palpi fuscous with the extremity of 

 each joint paler. The second and third antennial joints, taken together 

 are not longer than the fourth.
