front tibiae lightly curved, hind ones dilated towards and 

 notched at apex. Length, 1J-2 mm.

 smaller, elytra more parallel-sided, legs shorter, front tibiae 

 straighter, and hind ones not quite so wide at apex. 



Hab.— Lord Howe Island (A. M. Lea). Type, I. 6161. 



A variable species obtained in abundance on the island. 

 On some specimens the ground-colour is black, but on many 

 (especially females) it is not even a very dark brown ; the 

 prothorax is sometimes entirely dark, but usually has the 

 medio-basal portion obscurely paler, on some specimens the 

 only dark part is a median blotch ; on the elytra of the most 

 abundant form there is a single sub-basal flavous fascia, 

 commencing on each elytron near the shoulder, where it is 

 widest, and directed obliquely towards the suture, along 

 which it extends for a short distance ; but frequently a second 

 fascia may be seen at the apical third, it is often distinct but 

 never so sharply denned as the sub-basal one; even when both 

 of the fasciae are absent, however, their positions are usually 

 indicated by paler pubescence than elsewhere ; the legs are 

 frequently entirely pale; but the hind femora, or the four 

 hind ones, are sometimes more or less deeply infuscated; the 

 infuscation of the antennae also varies in extent and intensity. 

 On five specimens (both sexes) the general colour is of a 

 rather deep black, and the infuscation of the legs is extended 

 to the four hind tibiae and tarsi ; the pale pubescence is denser 

 and more conspicuous than usual in places, and forms two 

 very conspicuous elytral fasciae, occupying the positions of 

 the dermal fasciae (these being entirely absent). The punc- 

 tures of the upper-surface are somewhat obscured by the 

 clothing. 



Xylophilus norfolcensis, n. sp. 



d ■ Black or variegated, appendages in parts more or 

 less flavous. Moderately clothed with short, ashen pubescence. 



Head shining and with minute punctures. Eyes promi- 

 nent, widely separated, feebly notched in front. Antennae 

 not very long, second joint subglobular, slightly longer and 

 distinctly wider than third, third-seventh thin, the others 

 gradually increasing in width, eleventh briefly subovate, 

 almost as long as ninth and tenth combined. Prothorax 

 distinctly transverse, sides gently rounded, slightly wider 

 near apex than elsewhere ; with dense and sharply-defined 

 but not very large punctures. Elytra much wider than 

 prothorax, and distinctly wider than head, shoulders strongly 

 rounded, sides very feebly dilated to beyond the middle; 

 punctures about base much as on prothorax, but becoming 

 smaller posteriorly; with a feeble swelling on each side of
