Coleoptera.] SUBANTARCTIC ISLANDS OF NEW ZEALAND. 109 



peduncle transversely quadrate, slightly incurved at sides and apex so that its front 

 angles are acute. Palpi minute and rigid. Scrobes quite open above, extending 

 from near the apex, where they are deep, towards but not reaching the eyes. 

 Scape very gradually and only slightly incrassate, attaining the back of the eye. 

 Funiculus 7-articulate, basal 2 joints of equal length, 3rd rather shorter than 2nd, 

 joints 3-7 decrease in length, each longer than broad, all obconical. Cluh elongate, 

 triarticulate, oval, the intermediate joint transverse. Eyes very slightly convex, 

 distinctly faceted, quite lateral, free from thorax, obliquely truncate in front, sub- 

 acuminate. Thorax subquadrate, base and apex truncate, ocular lobes altogether 

 absent or scarcely appreciable. Scutellum proportionally small. Elytra very 

 slightly wider than thorax at the base, oviform, much narrowed and sometimes 

 subacuminate at apices. Femora simple, moderately inflated medially. Tibiae 

 flexuous, inwardly mucronate at the extremity, the anterior subserrate along the 

 inner face. Tarsi with dense brushlike soles, their 3rd joint appearing spongy when 

 examined directly from below, the slender basal portion of the first 2 and the ter- 

 minal one almost glabrous, 3rd moderately expanded and cleft almost to the base, 

 the 4th elongate, arched, its claws thickened at the base. Prosternum only slightly 

 incurved in front ; the coxae large and prominent, situated about midway between 

 the base and apex, almost contiguous, their cavities confluent. Intermediate coxae 

 moderately separated by the cuneiform mesosternal process ; the posterior widely 

 distant. Metasternum relatively short. Abdomen elongate ; basal segment nearly 

 double the length of the 2nd in the middle, its intercoxal suture strongly rounded ; 

 2nd not as long as the following 2 combined, its frontal suture nearly obliterated 

 in the middle, in reality, however, extremely fine and broadly outwardly curved 

 there ; 4th a little shorter than 3rd ; 5th elongate, subtrigonal, but truncate at 

 extremity. Epipleurae extremely narrow throughout. The mandibular scar is pre- 

 sent. The corbels of the posterior tibiae are simple, without any truncature at the 

 outer extremity. The whole structure, indeed, seems primitive. 



After prolonged study I fail to find any very salient characters. The rostrum 

 is much less pterygiate than the European Oliorhynchus. The Malayan Rhinoscapha 

 is somewhat similar in form, but one-half of the posterior corbel is truncate. Some 

 of the Polynesian genera have similar slender scales, but differ otherwise, Elytrurus, 

 for example, having prolonged elytral apices. Its systematic position must be in the 

 first section of the group, according to Lacordaire's classification. Catoptes is its 

 nearest ally here. 



Catodryobius vestitus, sp. nov. (Plate III, fig. 10.) 



Nigrescent, slightly nitid, antennae and tarsi rufo-piceous ; squamosity slender, 

 metallic, chiefly yellowish, but intermingled on some parts with green. 



Rostrum carinate along the middle, broadly grooved at each side of the middle, 

 finely rugosely punctate near the almost-nude apex, the other sculpture concealed by 

 the squamae. Thorax of equal length and breadth, its sides nearly straight behind, 

 a little narrowed anteriorly, slightly wider before the middle than elsewhere ; its 

 punctuation very irregular, near the sides the sculpture consists principally of short 

 irregular rugosities, it is nearly bare along the middle and on an elongate space near 

 each side, the rest of the surface bears numerous small scales. Scutellum squamose. 

 Elytra only moderately curvate at the sides, striate-punctate, interstices slightly
