3223. Ulonotus wallacei sp. nov. 



Oblong, elongate, transversely convex, opaque; fuscous, variegated 

 with yellowish-grey, obscure rufous, and black; the thoracic lobes, legs, 

 and antennae fusco-rufous, the middle of the tibiae often fuscous. 



Head narrowed anteriorly, with rather coarse brassy setae and 

 granular sculpture, the antennal prominences distinct. Thorax a third 

 broader than long, its frontal lobe largest and extending to beyond the 

 eye; the 2nd, just behind the middle, is much smaller, deeply and 

 rather widely separated from the 1st; 3rd barely half the size of 2nd, 

 and nearly forming the basal angle; disc uneven, with a large angular- 

 depression on the middle, a much smaller one at the base, the other, at 

 the apex, is not always distinctly angulate ; the setae are very irregularly 

 distributed, greyish-yellow, some are squamiform, others finer. Elytra 

 oblong, parallel, and as broad as the widest part of thorax; the series 

 of nodules nearest each side of the suture form almost continuous ridges; 

 their basal part is most elevated, so that the scutellar region seems de- 

 pressed ; the suture is much more finely nodose, and the series nearest 

 the sides are more or less rufescent ; the setae are greyish, some are 

 coarser than others, and those on the sides, like those of the legs, are 

 more or less erect. 



Antennae with rather dark slender setae; 2nd joint thick and usually 

 as long as the exposed portion of the 1st, these often bear coarse yellowish 

 setae; 3rd slender, and evidently longer than the contiguous ones; joints 

 4-8 decrease in length; club large, dark, its basal joint about as broad 

 as the other two. Basal three joints of the tarsi, together, rather shorter 

 than the terminal one. 



Underside nigrescent, opaque, with numerous distinct pale brassy 

 setae; it is closely granulate; the 5th ventral segment, however, is much 

 less so; metasternum, behind, grooved half-way along the middle. 



Its nearest ally is 1708 (U . rufescens), which may be distinguished by 

 the very short transverse basal joints of the club, less-convex eyes, and 

 different coloration. 



Length, 5— 5| mm. ; breadth, 2-2J mm. 



Wairiri, Seaward Kaikouras. Several specimens found under bark 

 by Mr. W. L. Wallace, whose name has been given to the species. 



3224. Notoulus demissus sp. nov. Notoulus Broun, Man. N.Z. Coleopt., 



p. 183 (Ablabus). 



Oblong, convex, subopaque; obscure fusco-rufous, the depressed 

 scutellar region and a large median spot across each elytron dark fuscous ; 

 legs ferruginous, antennae and tarsi somewhat fulvescent, thoracic lobes 

 testaceous; sparingly clothed with short, slender, more or less curled 

 flavescent setae. 



Head large, nearly as broad as the thoracic disc, with indistinct 

 granular sculpture. Thorax about as broad as long, excluding the 

 lateral lobes; uneven, with a large median impression which seems to 

 extend to the sides, distinctly and irregularly granulate; its sides 

 broadly explanate and bilobed ; the frontal lobe is large, with its anterior 

 angle projecting almost as far as, yet distant from, the centre of the 

 eye, the 2nd is cylindrical and situated between the former and the 

 base, posterior angles indistinct. Elytra twice the length of the thorax, 

 with obtuse shoulders, so that, at the base, they are no wider than the 

 thorax; their sides are studded with granules, and appear subserrate;
