112 SUBANTARCTIC ISLANDS OF NEW ZEALAND. [Cvleoptera. 



Catodryobius grandis, sp. nov. (Plate IIT, fig. 15.) 



R()J)i(.'<t. slightly nitid, piceo-niger, legs and antennae piceo-rufous. somewhat 

 unevenly covered with slender brassy squamae, and on the el\i:ra with some erect 

 yellowish setae. 



Rostrum one-fifth shorter than thorax, nearly plane above, nude ; irregularly, 

 moderately finely, yet distinctly punctured. Clijpeus rather convex, finely punctate, 

 with erect yellow setae at the apex. Head similarly sculptured, with a well-marked 

 elongate interocular fovea, the slender sc^uamae congregated near the eyes. Thomx 

 nearly glabrous on the middle, rather broader than long, widest near the middle, 

 obtusely rounded laterally ; the discoidal punctuation rather fine but close and 

 slightly rugose, near the sides the punctures are larger and much more distant from 

 each other ; it is slightly uneven, on the middle of the apex there is a minute angular 

 excision. Elytrn ample, widest behind the middle, rather wider than thorax at the 

 base, apices divergent and slightly though definitely protuberant ; their whole sur- 

 face minutely granulate or rugose ; they are relatively rather finely striate-jiunctate, 

 with a very few larger but not deep impressions behind ; 3rd interstices obtusely and 

 slightly elevated from base to apex ; the 5th also raised, though only from the middle, 

 and becoming plane near the extremity ; the sides slightly prominent ; on all these 

 the erect setae are more or less concentrated. Femora sparingly clothed with slender 

 scales, the tibiae setose. Scape subclavate and reddish at the extremity, distinctly 

 punctured, and bearing some yellow setae. Funiculus similarly setose, joints 5 and 6 

 moniliform, 7th transverse. Club rufo-fuscous, elongate. 



Underside glossy piceous, nearly nude, rather finely and irregularly punctured ; 

 basal ventral segment evidently medially incurved behind, the suture between it 

 and the 2nd well marked, 3rd and 4th deeply transversely depressed at the base, 

 5th emarginate at apex. 



This, the largest of the series, may be readily identified by a glance at the sub- 

 costate elytral interstices. The deciduous supplementary mandibles are present in 

 the specimen submitted to me. 



Length (rost. incL), 11^ lines : breadth, 4j- lines. 



Disajipointment Island. 



The type is unique, and was returned to Mr. Hudson. 



Inocatoptes, Broun, 1901. 



Allied to Catodryobius, but diftering therefrom as follows : — 

 Eyes transversely oval, not acuminate, their greatest bulk from above down- 

 wards. Mentum transversely quadrate, curvate and depressed in front. Ocular 

 lobes distinct, though not strongly developed. Anterior coxae quite contiguous, and 

 extending to the raised and thickened hind margin of the prosternum ; there is no 

 such margin in Catodryobius, and the coxae are more distant from the base of the 

 prosternum. The mesosterncd process is broader, and between the intermediate coxae 

 distinctly separated from the obtuse apex of the metasternum ; in Catodyrobius the 

 metasternum is cariniforni there. The mesostermim. itself is abbreviated so that 

 the middle coxae are almost in contact with the hind margin of the prosternum, 

 whereas in Catodrybius it is as long as the metasternum ; the intermediate, there-
