not perceptibly broader at the base than the thorax, very slightly bulging in 

 the middle, and gradually narrowed and prolonged at the apex, where they are 

 slightly divaricate; the surface has rows of very large punctures, from the 

 suture to the sides and extending to the middle. 



Several examples sent from Auckland by Mr. Lawson. 



Xylotoles rugicollis, n. sp. 



X. fusco-niger, subseneus, nitidus j thorace elongato-quadrato, supra passim 

 transverse rugato; elytris ellipticis, apice utrinque productis, acutis, supra 

 striatis interstitiis elevatis, f ulvo-guttatis ; antennis pedibusque castaneis. 

 Long. 4—6 lin. M, F. 



Distinguished by the thorax being elongate-quadrate in outline, a little 

 dilated immediately behind its anterior angles, where it is widest, and 

 covered with irregular transverse wrinkles. The sides have some patches or 

 lines of tawny pubescence, as well as the front of the head. The elytra have 

 no distinct shoulders, and are dilated in the middle, whence they taper 

 gradually to the pointed apices, most prolonged in the male, but not 

 divaricate ; their surface is coarsely sculptured, deeply striated almost to the 

 apex, and marked with large punctures. The underside is very glossy, with 

 spots of tawny tomentum on the sides of the breast and abdomen. 



Auckland {Mr. Lawson) ; a few examples. 



Xylotoles Icetus, White, Yoy. Ereb. and Terr., Ins. p. 22. 



This species (if I refer it correctly to White's X. Icetus) is shorter and 

 much more ovate than its allies, the apices of the elytra not being produced, 

 but somewhat obtusely rounded together. The colours are more gaily metallic. 

 White describes the thorax as violet, and the elytra green j but in a larger 

 series many varieties are seen, some being wholly brassy green, others coppery 

 or violaceous; the thorax and elytra concolorous or not. The elytra are 

 narrow and rounded at the shoulders. The thorax has a few coarse rugae on 

 the sides ; but is nearly smooth on the disk. 



Auckland (Mr. Lawson) ; several examples, measuring from 2 J to 4 J lines 

 in length. 



Xylotoles nanus, n. sp. 

 ? Xylotoles parvulus, White, Voy. Ereb. & Terr., Ins. p. 22. 



Similar in form to X. griseus, but much smaller and more densely clothed 

 with spotty or lineated griseous pubescence, with darker spots on the elytra, 

 forming in well-preserved examples a somewhat tessellated pattern, the dark 

 colour often concentrating in a patch on each side of the elytra. The thorax is 

 very similar in form, but the two transverse impressed lines are less marked. 

 The elytra are very nearly of the same width at the shoulders as the base of 

 the thorax, their apices are not prolonged but singly rounded, and they have
