326 COLBOPTERA. 



yellowish pubescence ; fusco-testaceous, terminal joints of antennae fuscous ; 

 elytra at the base nigro-fuscous for a third of their length but leaving the 

 shoulders yellowish, the hind part of this dark mark irregular ; fi'om the 

 middle of each elytron a broad blackish mark extends along the suture, but 

 at some distance from tiie apex is bent outwards, and at the side is slightly 

 prolonged forwards ; there are no othei' spots. 



Head finely punctured ; the sharply defined margin just behind the eves 

 denotes the limit of i-etraction. Thorax a third broader than long, curvedly 

 narrowed anteriorly, with defiexed and rounded angles there, the base 

 broadly rounded in the middle and sinuate towards the subrectangular 

 angles ; the disc without definite punctation but with numerous irregular 

 transverse marks ; midway from each side and the middle there is a rather 

 large, angular basal depression. Scutellum broad. Elytra closely adapted 

 to the thorax, four times its length, very little wider near the dark posterior 

 maik than at the base, gradually narrowed behind, with stiongly rounded, 

 dehiscent apices ; their sculpture, near the base especially, is rather coarser 

 and more punctiform than that of the thorax. 



Antennae and tibiae similar to those of H. acuttiivala : the eyes, how- 

 ever, are smaller. 



The coloration and marks most nearly reseml)le those of the northern 

 //. hifasciata, 716. 



Lengtli (head inclusive), 3 mm. ; breadth, 1 mm. 



Mount Hutt. I am indebted to Mr. T. Hall for mv specimen, found bv 

 him on the 15th March, 1913. 



Ohs. — From the same source 1 possess a pale straw-coloured individual 

 of H. nmhdata, 711, in which the elytra are feebly striate, and their apices 

 sharply rounded, but I do not consider it sufficiently distinct for separation 

 as a species.

Zenagraphus gen. no v. 



Body oblong, moderately convex, densel}' squamose. Rostrum thick, 

 not quite as broad as the head, shorter than thorax, somewhat pterygiate, 

 the triangular apical portion without well-marked lateral grooves, with a 

 single median carina. Mandibles vertical in front, curved at the apex, 

 strongly and subacutely bidentate at the inner extremity. Scrobes sub- 

 apical, deep and open above, extending obliquely towards but not reaching 

 the lower and front part of the eyes. Scape inserted near the apex, gradually 

 thickened, attaining the centre of the eye. Funiculus also stout, 7-arti- 

 culate, basal two joints nearly equal, not twice as long as board, joints 3-6 

 raoniliform and subtransverse, 7th rather larger. Club densely pubescent, 

 as iong as the terminal three joints of funiculus, closely articulated, ovate 

 and subacuminate. Eyes quite free from thorax, slightly convex, obliquely 

 oval. Thorax truncate in front, without ocular lobes, base feebly rounded. 

 Scutellum small. Elytra oblong, somewhat arcuate-emarginate at base. 



Legs stout, moderately elongate ; tibiae slightly fle.xuous and mucronate ; 

 posterior corbels with duplicate cilia and very narrow external truncature. 

 Tarsi with dense brush-like soles, not elongate, their penultimate joint some- 

 what expanded and bilobed. 



Mentum large, occupying the buccal cavity and concealing the palpi. 

 Prosternum only slightly emarginate. Front coxae prominent and con- 

 tiguous, intermediate slightly, the posterior moderately widely separated. 

 Metasternum short. Basal ventral segment rather longer than meta-
