323 Transactions. — Zoology. 



The shape of the body is elongate-elliptical, the elytra at the shoulders being 

 scarcely wider than the base of the thorax. The colour of the integument is 

 coppery brown, but veiled with a laid ashy pubescence, never dense enough 

 wholly to conceal the ground-colour — fresh examples showing, besides, a few 

 condensed white linear spots, placed some on the anterior disk and others as 

 an oblique macular fascia behind the middle ; but these spots are sometimes 

 wanting. The elytra are faintly striated (except the sutural stria), and have 

 a number of large punctures arranged in irregular rows near the base. The 



antennse are pitchy red, with the bases of some of the joints paler. 



Xylotoles humeratus, n. sp. 



X. griseo proxime affinis ; magnis nitidus ; elytris ad humeros thoracis basi 

 distincte latioribus, humeris rectangulatis, maculis pubescentibus fulvis ; oculis 

 pilis fulvis marginatis. Long. 3 — 5 lin. M. P. 



Difficult at first sight to distinguish from X. griseus, but certainly distinct. 

 The difference in general form first strikes the eye — a difference which arises 

 from the thorax being much shorter and more narrowed at the base, and from 



the elytra at the base being much wider, with wide outstanding rectangular 

 shoulders. The colour is also constantly different, being more brassy greenish 

 and shining, especially on the thorax. The general laid pubescence is greyish, 

 and the striae and punctures are nearly the same as in X griseus ; but the 

 denser pubescent spots are always orange-tawny and conspicuous, arranged 

 in two groups — one near the base (some of them forming an obliqbe line), and 

 the other behind the middle (forming a line oblique in the opposite direction 

 to the former). The orbit of the eyes has also a dense fringe of the same 

 tawny-coloured hairs ; and there is a patch of the same on each side of the 

 thorax. 



Many examples from Mr. Lawson of Auckland, mixed with X. griseus. 



Xylotoles subpinguis, White, Toy. Ereb. and Terr. p. 22. 

 One example from Mr. Fereday, Christchurch, agreeing well with White's 

 description. 



The species much resembles X. griseus, but has a more spotty pubescence 

 and the elytra are more prolonged and pointed at the apices (M.) 



Xylotoles nudus, n. sp. 

 X. elongatus, angustus, cuprascenti-niger, glaber, nitidus ; elytris basi 

 thorace vix latioribus, apice utrinque productis et paulo divaricatis, basi 

 grossissime lineatim punctatis ; antennis pedibusque castaneis ; femoribus 

 obscurioribus. Long. 4^ — 5 lin. 



Body entirely destitute of pubescence, except spots on the sides of the 

 ventral segments j antennas and legs finely griseous pubescent. Colour glossy 

 coppery black ; head and thorax impunctate and smooth. Elytra elongated,
