longer. Prothorax rather small, parallel-sided to near apex 

 and then strongly diminishing in width to apex; with dense, 

 partially-concealed punctures, and with a feeble, semidouble 

 median depression near base. Elytra much wider than pro- 

 thorax; parallel-sided to near apex; with dense and fairly 

 strong punctures about base (especially in a shallow depression 

 behind a feeble subscutellar elevation), but becoming smaller 

 posteriorly. Legs rather long and thin ; hind femora stout, 

 hind tibiae thin and parallel-sided almost throughout. 

 Length, lf-2 mm. 



9 . Differs in having much smaller eyes, much more 

 distant from each other; antennae much shorter with third 

 joint distinctly separated from fourth, and the eleventh joint 

 larger in proportion; prothoracic depression more conspicuous; 

 elytra larger and less parallel-sided ; abdomen more convex 

 and legs shorter, with hind femora thinner. 



Rah. — Lord Howe Island; New South Wales: Sydney 

 (A. M. Lea), Hornsby (C. Gibbons). 



The third joint of the antennae in the female is very 

 short, but in the male it is still shorter, and so closely applied 

 to the fourth that except on close examination the two appear 

 as but one, and consequently the antennae appear to be ten- 

 jointed. On each elytron there is an infuscate-elongated O, 

 each O enclosing an elongated spot of similar colour to the 

 other parts of the elytra; each commences at the basal fourth, 

 and ends slightly beyond the middle, it almost touches the 

 suture and near the base is connected with the side (so that 

 as viewed from the side on one elytron the appears like a 

 Q). The specimens from Sydney agree in structure with the 

 types, but differ in being considerably paler; on the male 

 the O on each elytron is traceable, although not very deeply 

 infuscated, and the four hind femora are moderately infus- 

 cated ; on the female the O on each elytron is paler and 

 not complete, and only the hind femora are infuscated. The 

 specimen from Hornsby agrees well with the type in colour 

 as well as in structure. 



Xylophilus leucosticttjs, n. sp. 



<5 . Blackish, parts of under-surface and of appendages 

 obscurely paler. Clothed with dark pubescence, but becoming 

 paler on head and parts of under-surface, and forming dis- 

 tinct spots on prothorax and elytra. 



Head with dense, partially-concealed punctures. Eyes 

 large, moderately separated, deeply notched. Antennae 

 moderately long and rather stout, second joint short, trans- 

 verse, and closely applied to third, third longer than first 

 and second combined, slightly dilated to apex and almost
