at the shoulders. The thorax lias a few coarse rugae on the 

 sides ; but is nearly smooth on the disk. 



Auckland (Mr. Lawson) ; several examples, measuring from 

 2f to 44 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 concen- 

 trating 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 an 

 irregular number of punctures near the base arranged in rows } 

 they are destitute of impressed strice, except the usual sutural 

 one. 



A. further distinction from X. griseus, even the smallest ex- 

 amples, is the colour of the antennas, the apices of the joints 

 being always distinctly fuscous or black. 



The general ground-colour is extremely variable, from 

 brown with a scarcely perceptible brassy tinge to dull tawny 

 or pale testaceous. Long. 2-2f lin. 



Auckland. Mr. Lawson has sent home a very large number 

 of this small, variable species. 



White's description (!) of his X. parvulus consists of the 

 following words : — " Testaceous, covered with a greyish pu- 

 bescence ; base of elytra with several dots and four rows of 

 small punctures in two lines, extending to the middle of 

 elytra." No size is given ; and the description applies equally 

 well to our X. aigrotus. 



Xylotoles cegrotus, n. sp. 



X. elongatus, angustus, omnino fulvo-testaceus, subtiliter griseo- 

 pubescens ; elytris <$ apice dehiscentibus, singulatirn prolongatis, 

 perparum divaricatis, 5 acute conjunctim rotundatis. Long. 

 2|-2| lin. 



Similar in form to X. nanus, but always of a tawny testa- 

 ceous colour, with fine scant grey pubescence, arranged more 

 or less in lines on the elytra. The antennas are not ringed 

 with dark colour, but pallid like the rest of the body, or at 

 most a little browner at the extreme tips of some of the joints. 

 The elytra arc relatively much longer and are narrowed and
