long. Protliora.c at ba.se about tbrice as wide as the median length, ba.se bisinuate, 

 apex gently incurved to middle, margins very narrow; punctures rather dense 

 and small, but sharply defined. Elytra with outlines continuous with those of 

 prothoras, widest at about basal fourth; with dense and moderately strong punc- 

 tures, more or less seriate in arrangement. Abdomen with coxal lines distinct, 

 and marking the outer edge of a plate, on each side of which the punctures are 

 larger than elsewhere. Length, 2.25-2.75 mm. 



Hab.— New South Wales: Forest Reefs (A. M. Lea). 



An evenly elliptic, moderately convex species, with the general outlines of 

 mainland specimens of E. tasmaniae, but elytra with rather dense pimctures, 

 many of which are in regular lines, but not in impressed striae, whereas on that 

 species the striatiou is conspicuous and the punctures much less in evidence; on 

 the pronotum, however, the punctures are alike on both species. Structurally it 

 is extremely close to and is certainly congeneric with the New Zealand Triplax 

 brouni Pasc, but with stronger punctures and slightly different antennae, at first 

 glance the two species appear to be identical. There are twelve specimens of 

 the typical form before me. 



Var. I. Six specimens from Forest Reefs (Lea), and one from Blue Moun- 

 tains (Dr. E. W. Ferguson), differ in having an obscurely reddish fascia (inter- 

 rupted at the suture) at the base of the elytra, more of the apex reddish, and the 

 under surface reddish but with the metasternum infuseated. Compared with E. 

 bivulneratus these specimens differ in being narrower and less convex, in having 

 the basal markings more obscure, more of the apex reddish, the punctures much 

 stronger, and the coxal lines more distinct. 



Edxestus ateRj n. sp. 



Black; parts of under surface obscurely diluted with red, legs antennae and 

 palpi castaneous. Glabrous. 



Head with small but sharply defined punctures; a small fovea on each side 

 of clypeus. Antennae short, basal joint large; club slightly wider than long. 

 Prothorax not thrice as wide as long, base bisinuate and much wider than apex, 

 the latter gently incurved to middle, sides very finely margined ; punctures' sparse 

 and small. Elytra with sparse and small punctures, some of which appear to be 

 in feeble lines towards base. Abdomen with coxal lines enclosing a distinct plate 

 on each side. Lengfh, 2-2.25 mm. 



Hob. — Queensland: Brisbane (A. J. Coates). 



The outlines are intermediate between those of E. bivulneratus and E. 

 ventralis; from the former it is also distinguished by the absence of basal mark- 

 ings on the elytra, from the latter by the considerably smaller and sparser punc- 

 tures; it is slightly more convex than E. medioniger. The muzzle is not as dark 

 as the base of the head, but at first glance the whole of the upper surface ap- 

 pears to be of a polished black; the joints preceding the club are slightly darker 

 than the rest of the antennae, but this appears to be the case with most species 

 of the genus. 



El'xestus atropolitus, n. sp. 



Black, highly polished ; legs antennae and palpi castaneous, tips of elytra 

 obscurely diluted with red. 



Head with sparse and minute punctures, sharply defined only on clypeus. 

 Antennae short, club slightly wider than long. Prothorax about thrice as wide 

 at base as the median length, apex gently incurved to middle, sides and base very
