570 COLEOPTERA 



supra grosse discrete punctate ; thorace tuberculis duobus acutis' latera- 

 libus, anteriori minuto instructo. 



Long., 3-5 lin. 



Tairua, near Auckland (Capt. Broun). 



Differs from the typical species in the proportions of the antennal 

 joints three to five, but agreeing in the double armature of the sides of 

 the thorax ; the third to seventh joints are linear and nearly equal in 

 length, the fourth being a little the shortest. The surface of the thorax 

 is free from tubercles, and is covered with large punctures, except along 

 the dorsal line. The body is glabrous, except for the scattered long 

 hairs ; the antennae are densely pilose. 



998. D. brevicorne, n.s. Rather short, moderately convex and 

 shining, sub-parallel. Head short, rugosely punctate and pilose. An- 

 tenna rufo-testaceous, fourth joint short, the first seven hispid, remaining 

 joints finely pilose. Thorax rufous, sub-quadrate, rather short, the 

 sides unevenly rounded, armed with an acute tubercle behind the 

 middle and an obtuse one in front ; the disc is uneven, not distinctly 

 tubercular, but with two obtuse elevations in front ; it is sparingly 

 punctured, the elevated portions and a central spot smooth, and bears a 

 few pale yellow hairs. The elytra are parallel-sided, with rounded 

 apices and prominent shoulders ; they are not much wider than the 

 thorax and scarcely narrowed behind ; their surface is punctured 

 throughout, and they bear many short depressed griseous hairs ; there is 

 an indistinct pallid longitudinal line about mid-way between the suture 

 and margin ; the colour is testaceous, the sides, base, and a narrow 

 sutural line infuscate. The legs are rather short, of a pale rufous colour, 

 and clothed like the antennae. 



Length, 4f lines. 



I have only seen one example of this species, which I found at 

 Tairua ; it is well differentiated from D. sublineata, by its shorter thorax, 

 comparatively broader apex of elytra, which is not attenuated, and by 

 the remarkably short antennae.

Appearance of Clytus ; head scarcely prone, immersed in the pro- 

 thorax almost up to the eyes, elongated in front ; eyes reniform, dilated 

 behind ; antenna scarcely longer than the body, filiform, eleven-jointed, 

 third and fourth joints somewhat shorter than the following; thorax 

 without spines, longer than wide, the sides nearly parallel, transversely 

 wrinkled on the disc ; elytra flattened on the back, gradually attenuated 

 towards the tip, the tip itself rounded ; legs somewhat elongated; femora 

 simple.
