556 NEW SPECIK8 OF AUSTRALIAN COLEOPTERA, xui., 



and four depressions at base. Elytra much wider than prothorax, 

 very feebly dilated to beyond the middle, with a feeble swelling 

 on each side of scutellum, and a shallow depression at the side 

 of, and behind, each swelling: with dense and sharply defined, 

 but not very large punctures on basal half, becoming smaller 

 posteriorly. Leys rather long and thin: hind-tibife no wider at 

 apex than in middle. Length, 1 J-2^ mm. 



9. Differs in having the eyes smaller and less close together; 

 antennae much shorter, with several of the joints transverse; ab- 

 domen more convex, and legs somewhat shorter. 



Hab. — Tasm.: Waratah, Swansea, Frankford, Hobart, Mount 

 Wellington, Huon River (A. M. Lea). 



In general appearance, close to X. acacice, but antennse of male 

 conspicuously longer, punctures distinctly coarser, and upper 

 surface without apparent "bloom," owing to the pubescence being- 

 somewhat longer, although still very short. At first glance, the 

 antennae of the male resemble those of the male of X. co7ispicil- 

 latus, but all the joints are distinct. The antennae are consider- 

 ably longer than in X. uiconspiciiiis; they are usually infuscated 

 from near the base, but sometimes are entirely pale; occasionally 

 parts of the femora are lightly infuscated. One specimen has 

 the prothorax quite as black as the head, and the elytra almost 

 as black. The specimen (^) from Waratah has the antennae 

 rather longer than usual, and entirely infuscated; the femora 

 deeply, and the tibise lightly, infuscated; and almost the whole 

 of the body-parts deep black. It certainly "looks" as if it 

 belonged to a different species, and to a thinner and longer male 

 from Frankford; but the differences appear to be varietal only 

 from the normal form. 



Two males from Western Australia (Donnybrook and Karri- 

 dale) are paler than the Tasmanian specimens, with thinner and 

 longer antennae and legs, and more conspicuous, elytral punctures; 

 they appear to represent a variety only. 



Xylophilus micromelas, n.sp. 

 (J. Black, parts of undersurface and of appendages obscurely 

 paler. With rather sparse and minute, ashen pubescence,
