each other. Thuiux a tliird bioadt-i- tliau long, a good deal, and some- 

 what abruptly, narrowed anteriorly; its [)unetati(tn proportionally 

 coarse, not very close, and rather irregular, along the middle there is 

 aji abbreviated smooth line. Elytra cordit'orm, oblique towards each 

 si(K at the base, whi ii' tlioy sc-arccly exceed that of the thora.x in width, 

 thev arc broader iirar the middle, much nariviwed and nearly, but not 

 abruptly, pei-iienditiilai behind ; eaeli with ."i deep and broad distinctly 

 piinctuied striae neai- the suture from base to apex, tlie others nearer the 

 side are less evident; interstices without nodosities. 



Legs robust and elongate; anterior tibiae obliquely truncate from 

 the middli' to the actiminate inner extremity. Tarsi triarticulate, basal 

 two joints strongly transverse, the terminal not quite as broad, slightly 

 excavate at the apex, l)ut without claws. 



Seajie medially inserted, olavate at the extreniity, and extending 

 backwards to the centre of the eye. Funiculus much longer than the 

 scape, basal joint of about the same length but much thickci- than the 

 slender 2nd, both narrowed towards the base, 3rd and 4tli slightly longei- 

 than l.]u,i(l, joints .")- 7 moniliform ; club elongate-oval, its 1st joint 

 obviousl\ smaller than and distinctly marked off from the large quadrate 

 2nd. the terminal acuminate. 



Coxae widely separated. Prosternum plane, without any trace of 

 rostral canal. Scutellum absent. 



In form and structui'c it most nearly a])proaches G. rugulosus, 1672, 

 which, howevei-, is a brighter insect, a large portion of the elytra being 

 chestnut-red; the tiioracic line is more obvious; the elytra are not 

 distinctly sulcat-e, the interstice nearest the suture is somewhat elevated, 

 a]id the surface generally is more or less transversely rugose. G. setJger 

 is also somewhat similar, l)ut it is shining, its thorax is nearly smooth, 

 and the setae borne ])y the elytra are distant from each othei-, slender, 

 and curled. 



This is the fifteenth species now on record, and, all l)eing small, their 

 discrimination is not an easy matter. 



Length (rostrum inclusive), 1§ mm. ; breadth, 1 i 



Great Barrier Island. A single individual was picked out of a small 

 bagful of leaf-mould sent to me by Mr. F. Flynn. 



3451. Geochus inorosus sp. nov. 



Subopaque, fusco-nigcr, antennae and tarsi rufo-castaneous, elub 

 piceous. 



Rostrum minutely as^jcrate, with a slight carina separating the 

 shallow grooves, which are broadest in front. Thorax bi-oader than 

 long, not abru])tly jiarrowed in front; a little uneven, broadly obli(iuely 

 impressed before the middle, with a slightly raised median line not 

 reaching the base, the punctures are distinct b\it irregular, some ^)eing 

 closer tlian others, many are filled with pale scale-like matter, and there 

 is a sliort basal fringe fornie(l ef a similar substatice. Elytra nearly 

 Iwict' as long as thorax, not Inoader than it is at the base, but quite 

 a third broader in line with the posterior feniora, obliquely narrowed 

 apically; their suiface uneven, eacli elytron having 3 basal elevations, 

 the humeral shortei- than that on the 3rd inter.stice, the central not 

 touching the basal margin; an oblique series extends inwardly from 

 beliind the middle, the lateral is not prominent, the next is round and 

 ]>i-ominent, the innermost is largest and seems dui)licate, tliei-e being a 

 •lividitig row of suiall jtunetures, it is situated on tlie top of the apical 

 declivity on the 3i-d interstice; just bflow the last, but nearer the suture, 

 another narrower elevation proji-ets backwards; the pujictures are dis-
