Peript\-ctus latericollls, n. sp. 



Red; head, scutellum and most of prothorax infust-ated, apical half of an- 

 tennae hlackish. i>ach shoulder with a fiavous spot. Upper surface glabrous, 

 under surface slightly pubescent. 



Head with a small impression near each eye. Antennae moderately long, 

 fii-st joint stout, second slightly longer, and mucii thinner than first, ninth- 

 eleventh foi-miug a rather wide club. Prothorax along middle longer than width 

 of apex, sides thickened, on basal half strongly raisetl and almost parallel, strongly 

 nan-owed and less elevated to apex, which is gently emarginate; punctures 

 sparse and inconspicuous. Elytra wider than prothorax, sides moderately 

 rounded, shoulders rather strongly raised; with rather sparse and small punc- 

 tures, but in places seriate in arrangement. P roster num with chin-piece sub- 

 triangularly advanced, a groove on each side of it. Length, 2.5 mm. 



Hab. — Queensland: Mount Tambourine (C. Wild). Unique. 



Larger than P. russulus, with the sides of prothorax suddenly and strongly 

 elevated in middle, and with the chin-piece more prominent, etc.; it differs in 

 many respects from the description and figure of P. eximius. The hind angles 

 of the prothorax are almost spiniform, and project obliquely outwards; its disc 

 is deeply infuscated, with the sides, especially in front, paler; part of its under 

 surface is also dark; the punctures of the under surface are rather sparse and 

 small on the abdomen, rather large Init sparse on sides of metasternum, and 

 fairly dense and large on parts of the prostemum. 



Idiophtes viridis, n. sp. 



Dark metallie-g^-een, with a coppery gloss; under surface, legs, antennae and 

 palpi more or less castaneous. Upper surface moderately densely clothed with 

 long, subereet pubescence, under surface and legs with much shorter and de- 

 pressed pubescence. 



Head rather wide; with dense, small, and (when not partially obscui-ed by 

 clothing) sharply defined punctures. Antennae moderately long, basal joint 

 stout, about lialf as long again as second, second stouter and slightly longer than 

 tliird, fourth and fifth slightly decreasing in length, sixth and seventh slightly 

 shorter and wider tlian fifth, eighth-tentli fonning a conspicuous club, eighth and 

 ninth each about a-s long as first, but much wider, tenth about half as long again 

 as ninth. Prothorax at base about thrice as wide as the median length, sides 

 strongly rounded, apex much naiTower than base, a conspicuous groove towards 

 each side, becoming wider at base, a narrow impressed line very close to base; 

 punctures crowded and sharply defined. Elytra strongly convex, sides subcon- 

 tinuous with those of prothorax, a small tubercle towards each side near apex; 

 with rows of fairly large punctures in rather shallow striae; interstices with 

 small, dense punctures. Length, 2 mm. 



Hab. — Tasmania: Hobart (A. M. Lea). 



A beautiful little species of which four specimens were obtained from moss. 

 Structurally it is close to I. hrevis, and the antennae are also ten-jointed; but 

 the ujiper surface is green, with longer clothing, and the prothoracic punctures 

 are mucli more conspicuous. 



Idiophye.s dubius, n. sp. 



Reddish-castaneous ; legs, antennae and palpi somewhat paler. Not very 

 densely clothed with moderately long, subereet setae or pubescence.
