88 COLKOPTERA 



eleventh ovate, about as long as ninth and tenth. Head shining, 

 blackish red, with a punctiform impression on the vertex, and many 

 punctures along the inner side of each eye but not encroaching on the 

 smooth median space. Pivtlwrax transverse, a little convex, finely 

 margined, widest in front, rounded towards its base ; there are two 

 smooth longitudinal spaces on the disc and three punctate linear spaces, 

 each consisting of two or more almost regular rows of punctures ; it is 

 shining dark brownish red in colour, and, like the head, destitute of 

 pubescence. Elytra broader than thorax, moderately punctured, their 

 pubescence cinereous ; they are a little glossy, dark chestnut red, with 

 the hind and side margins more or less piceous. Abdomen oblong, 

 castaneous-brown, not perceptibly punctate, and very sparsely pubes- 

 cent. Legs reddish. 



Length, i-| ; breadth, nearly J line. 



I have only one mutilated individual, which I found at Tairua. The 

 punctation of the thorax is distinctive. 



i6o. G. Sternale, n.s. Antenna ferruginous, the eleventh and the 

 two first joints paler ; joints four to ten gradually incrassated, the terminal 

 joint twice the length of the tenth. Head brownish-red, shining, seem- 

 ingly impunctate. The prothorax is transversal, rounded laterally, 

 distinctly punctated, wath a few pallid hairs ; it is of the same colour 

 as the head, and shining. Elytra rather dull ; each with a large space 

 extending from the shoulder to the suture castaneous, the remainder 

 blackish ; they are moderately finely punctured, and clothed with ash- 

 coloured hairs. Abdomen castaneous, more glossy than the elytra, the 

 fourth and fifth segments piceous, punctate and pubescent. Legs of a 

 yellowish chestnut colour. Metasternum castaneous ; lower surface of 

 the abdomen rather darker and clothed with greyish pubescence. 



It may be easily recognized by the thoracic sculpture, chestnut- 

 coloured breast, and hairy abdomen. 



Length, i line ; breadth, nearly \. 



I found two specimens near Whangarei Harbour. 



i6i. G. nug'ax, n.s. Antennce rather elongate, not much 

 thickened apically ; their three basal joints testaceous, third slender, 

 shorter than second ; joints four to ten duller in colour, eleventh fuscous. 

 Head glossy, reddish-black, apparently without sculpture. Prothorax 

 shining, brownish-red, without definite sculpture ; it is rounded laterally, 

 and, like the head, quite nude. Elytra bright reddish-brown, shining, 

 a good deal sinuated near each hind angle, closely punctated, 

 sparingly pubescent, with an obvious lateral impression on each near 

 the middle. Abdomen somewhat glossy, its three basal segments cas- 

 taneous, the others pitchy, punctate, and clothed with cinereous 

 pubescence. Legs infuscate, the tip of the femora and the tarsi testa- 

 ceous. Under-side shining ; the metasternum and abdomen smooth 

 and black. 



The species may be identified by the glossy black metasternum and 

 abdomen.
