928 COLEOPTERA 



Like H. picea (No. 1173) ; more glossy, the two fovea-like depres- 

 sions on base of thorax less obvious, the elytra not depressed before 

 the middle, more strongly punctured, and with narrower, slightly- 

 raised intervals. 



Length, i-^- lines ; breadth, \. 



Taieri: Mr. S. W. Fulton. (Sent as No. 124.) 



1665. H. obsoleta, n.s. Shining, black, claws castaneous; 

 covered with very short, cinereous (sometimes greenish) hairs. 



Head indistinctly bi-impressed, finely punctate. Prothorax finely 

 and distantly punctated, with more minute punctures between the 

 larger ones, slightly uneven, but with only two well-marked depres- 

 sions, near the base. Elytra rather deeply impressed before the 

 middle, with some rows of fine punctures on their anterior portion 

 and but little more than mere indications of striae behind. 



Larger than the typical form (No. 1173), elytra more evidently 

 depressed before the middle, but without any distinct punctation 

 beyond that point.

Ceratognathus (P. 252). 



1666. C. gibbosus, n.s. Oblong, convex, black, densely 

 clothed with white and pale greyish-brown, depressed, roundish 

 scales ; legs and antennae pitchy-red. 



Head elongate, much narrowed anteriorly, middle of vertex 

 nearly smooth, most closely punctured at the sides ; mandibles not 

 broad, without distinct protuberances ; eyes small, scarcely convex, 

 distant from thorax, truncate behind. Antenna elongate, basal arti- 

 culation long and curved; second rather longer than broad; joints 

 3-5 elongate, about equal ; sixth and seventh a little angulated : 

 club moderate, the leaflets separate. Prothorax widest behind the 

 middle, narrowed towards the front, base deeply sinuated, apex 

 deeply emarginated, anterior angles prominent yet remote from the 

 eyes ; coarsely and closely punctured, the disc with two crests, the 

 sides somewhat flattened. Elytra short, sub-parallel, sutural region 

 much elevated, shoulders raised ; their punctation coarse, concealed 

 in some places by blackish scales. Underside with scales and 

 greyish hairs. Legs squamose and hairy ; tibiae finely crenulated, 

 the anterior with one median tooth. 



The small, depressed, posteriorly-truncated eyes, narrow conical 

 head, and gibbose elytral suture are characteristic. 

 5 . Length, 4^ lines ; breadth, 2^. 



I am indebted to Mr. Crisp, of Parua, Whangarei Harbour, for 

 this curious form. 



OBS. Lacordaire treats Mitophyllus as but another name for 

 Ceratognathus : had it been otherwise I would have placed this species 

 and C. macrocerus in that genus.
