3340. Anthribus wairirensis sp. nov. 



Oblong, subopaque, variegate ; piceo-fuscous, legs and antennae 

 testaceous, the tibiae and tarsi with dark spots ; pubescence greyish, 

 unevenly distributed. 



Rostrum broad, shorter than thorax, flat in front, transversely impressed 

 between the antennae and eyes, closely punctate. Thorax slightly broader 

 than long, its basal portion abruptly, the anterior gradually, narrowed ; 

 it is moderately coarsely and closely punctured ; the carina is distant from 

 the elytra, obtusely angulate in the middle, bent, but not forming sharp 

 posterior angles, and extending forward only about a fourth part of the 

 length of the sides. Elytra oblong, irregularly and rather finely seriate- 

 punctate, each elytron with a large basal and post-median nodosity, and a 

 smaller contiguous pair in line with the others on the summit of the 

 declivity. 



Antennae evidently elongate, their 5th joint reaching backwards to the 

 middle of the elytra, the others broken off, 3rd joint distinctly longer 

 than 4th. 



Allied structurally to A. laetabiUs (2231), but much darker, less brightly 

 variegated, and smaller. The eyes less prominent in front and with a 

 small semicircular notch there. The thoracic carina a little farther from 

 the true base. The hind legs are shorter. The nodosity behind the middle 

 of each elytron is more prominent. A. impar is perhaps the nearest species, 

 but it, too, is prettily variegated, and its antennae are shorter.

3341. Didymocantha media sp. nov. Didijmocantha Newman, Man. 



N.Z. Coleopt., p. 568. 



Elongate, moderately nitid, very sparsely clothed with pale slender 

 hairs ; head and thorax testaceous, elytra, legs, and antennae much paler. 



Head impressed between the antennae, rather more closely punctured 

 there than it is behind ; it is distinctly angulate, or produced in front of 

 each eye. Thorax of equal length and breadth, but only a fifth of the 

 length of the elytra, with distinct median lateral tubercles, the frontal 

 small or obsolete ; its discoidal punctures rather coarse, irregularly dis- 

 tributed and rufescent, but becoming finer near the apex ; behind the 

 middle there is an almost smooth space, another elongate slightly raised 

 one near each side, and a pair of smaller ones near the front, but none of 

 these are definitely marked, and there are no discoidal tubercles. Elytra 

 subparallel, very gradually narrowed backwards, with separately rounded 

 apices ; they are rather coarsely but not closely or quite seriately punctured 

 as far as the hind thighs, more sparingly behind these, the punctures are 

 reddish, there are no vein-like marks, but a pair of very oboslete costae 

 may be detected on each elytron. 



Antennae distinctly pubescent throughout, basal joint punctate, 4th of 

 about the same length as the contiguous ones, the 9th attains the apex. 



The greater length and rufescent punctures differentiate this from 

 D. aegrota, whilst the double armature of the sides of the thorax and ivory- 

 like lines on the elytra distinguish my D. pallida.
