592 COLEOPTERA 



somewhat obtuse point. The head is rather long posteriorly, where its 

 sides are sub-parallel ; the forehead is almost perpendicular, the vertex 

 concave, with a continuous dorsal line, which is most distinct on the 

 occiput. The thorax is moderately convex, sub-quadrate, unarmed, and 

 rounded laterally. Elytra convex, wider and three times longer than 

 thorax ; shoulders prominent ; sides nearly straight towards the middle, 

 immediately behind which they are widest, abruptly deflexed ; apices 

 rounded, with a not very close suture ; they are transversely depressed 

 near the base, and gradually declivous posteriorly. The legs are 

 moderately long and robust, the femora inflated, and the tibiae slightly 

 incurved ; the tarsal joints one to two are sub-triangular ; third bilobed ; 

 claws divaricate. The front pairs of coxce are globose ; the pro- and 

 mesosterna between the coxse moderately broad and almost plane. 

 The above corresponds with examples in my collection.

Antetittce fuscous ; the basal portion of joints four to six is annulated 

 with white hairs, the external fringe corresponding in colour ; occasion- 

 ally the white colour is perceptible on other joints. The head is of a 

 dark blue, almost purple colour, somewhat rugosely sculptured, especi- 

 ally behind the eyes, and bears short yellow pubescence, arranged in two 

 lines, proceeding from the eyes along the occiput, besides many small 

 patches irregularly disposed over the rest of the surface. The thorax 

 is a little depressed transversely near the front and base and transversely 

 wrinkled ; the ground-colour and pubescence are precisely similar to 

 those of the head, but the tomentum does not assume any particular form. 

 Each elytron bears three discoidal longitudinal costse and a less obvious 

 marginal one ; the inner is merely sutural, the second obliterated at the 

 base, and none reach the apex ; the second and third interstices are 

 depressed, and all are more or less irregularly sculptured ; the basal 

 portion granulated ; the general ground-colour is a greenish-brown, the 

 costse are reddish-castaneous, the scutellar pubescence yellow, the 

 remainder mostly white ; the latter is disposed in small patches, but 

 usually becomes linear on the second and fourth interstices behind the 

 middle ; there is an indistinct medial fascia and a spot on the second 

 and fourth interstices fuscous ; the external margins are ciliated with 

 white hairs, the apices most so. The legs are infuscate and pubescent, 

 and the two hind pairs of tibia?, near the extremity, are distinctly pilose. 



Length, 5-8 lines. 



The above description, generic and specific, has been drawn up from 

 two specimens which I had collected at Tairua ; the colour sometimes 

 varies, but the markings seldom differ.

Head prone, antetnicz longer than the body, slender, eleven-jointed ; 

 thorax nearly cylindrical, straight on the sides ; elytra of much the same 

 width as the thorax, convex on the sides, pointed at the end ; legs 

 moderate ; femora swollen at the end.
