ANTHRIBIDAE. 73 



the thorax and the middle of the base there are some tawiiy setae ; knees 

 and tarsi dark red, the tibiae with a patch of fine grey setae above the 

 middle ; antennae shining, ferruginous, the tips of joints 3-7 piceous ; club 

 opaque, finely pubescent, piceous. 



Rostrum subquadrate, angularly emarginate in front ; coarsely, closely, 

 and rugosely punctate, as is the head. Thorax of equal length and breadth, 

 gradually narrowed from behind the middle to the apex ; the carina medi- 

 ally subtruncate, slightly sinuate towards the sides, bent forwards there 

 but not angulate ; its sculpture like that of the head ; there are a few 

 grey setae at the sides. Elytra oblong, a little wider than the thorax ; on 

 each there are 3 conspicuous nodosities or crests in line with the 3rd inter- 

 stices — one basal, another behind the middle, the third on top of the declivity 

 — these appear to be sooty-black, but the basal one has 2 grey specks, on 

 the others a few crimson setae can be seen ; outside the central one there are 

 2 slightly raised spots of the same sooty hue ; they are seriately punctured. 

 Pygidium subquadrate, flat behind, with depressed tawny setae, the apical 

 margin, however, is bare. 



In all structural details precisely similar to 966, A. hullatus.

3146. Anthribus suspectus sp. nov. 



Suboblong, subopaque, pubescence greyish ; coloration variable, usually 

 piceous, posterior declivity greyish, legs pitchy or rufo-fuscous, tibiae with 

 a grey spot above the middle, front and base of thorax wdth some tawny 

 or fuscous setae, near each eye and on the scutellum there are grey specks. 



Rostrum, head, and thorax coarsely, rugosely, and closely punctured. 

 Elytra with irregular series of distinct punctures ; each with 3 nodosities 

 or crests, placed as in A. maurus. 



I found five specimens of this species in different locahties. The descrip- 

 tion of A. bullatus Sharp contains no allusion to sculpture beyond speci- 

 fying the presence of 2 crests on each elytron. A. suspectus may be at once 

 distinguished from that species by its trinodose elytra, and the entire absence 

 of the conspicuous grey confluent patches which cover the greater portion 

 of the rostrum. The generic characters are the same in both species.

3147. Didymocantha cognata sp. nov. Gen., Man. N.Z. Coleopt., p. 568. 

 Elongate, subdepressed, shining, variegate, pubescent ; head and thorax 



piceous ; elytra fuscous, each with 3 large testaceous spots ; antennae and 

 femora ferruginous ; tibiae and tarsi flavescent. 



Head irregularly punctate, more finely behind than on the vertex, with 

 numerous slender yellow hairs. Thorax of equal length and breadth, the 

 lateral post-median tubercle acutely prominent ; on the disc, behind the 

 middle, there is an elongate smooth obtuse elevation, and near each side 

 a flattened angular smooth space, before the middle a pair of distinct shining 

 tubercles, and at each side, a little nearer the front, an indistinct flattened 

 tubercle ; the pubescence on the middle is like that of the head, but at 

 the sides is quite dusky ; the punctation is moderately coarse and irregu- 

 lar. Scutellum triangular, medially impressed, testaceous. Elytra elongate,
