very wide and feebly triangularly produced in middle. Fourth 

 segment of abdomen strongly incurved to and very narrow across 

 middle. 



Length 3 mm. 



Hah. W. Australia : Swan River, Darling Ranges 

 {A. M. Lea). 



The sutural marking appears as an elongate triangle 

 just touching the apex, the dark lateral markings do not 

 extend quite so far. A second specimen differs in having 

 the apical third of head, the apex base and sides of pro- 

 thorax and the entire abdomen reddish ; its elytral mark- 

 ings consist of a triangular patch (no longer than wide) 

 about scutellum and the shoulders greenish-black, and an 

 infuscate blotch on the sides about the middle. 



In appearance resembling the preceding species to a 

 certain extent but antennae shorter, scutellum distinctly 

 notched, prothorax partly dark and elytral markings of 

 different shape. From virgatus, n. sp., to which it appears 

 to be closer, it differs in its more distinctly notched 

 scutellum, partly dark prothorax, rather denser punctures 

 and smaller sub humeral lobes. 



LOXOPLEURUS ABSONUS, n. sp. 



(Plates XXIV, XXVI, figs. 100, 101, 201.) 



1^ . Suboblong, subopaque. Chocolate-brown, pygidium, apex 

 of abdomen, base of antennae and legs (tarsi excepted or not) 

 paler. 



Head with small but moderately dense punctures. Antenna 

 thin, the length of body, second joint almost as long as third, third 

 and fourth subequal and distinctly shorter than fifth. Prothorax 

 not twice as wide as long ; with dense and clearly cut but small 

 punctures ; regularly and rather strongly convex ; oblique impres- 

 sions absent ; margins narrow. Saitellum fully twice as long as 

 wide, base entire and not much wider than apex. Elijtra briefly 

 oblong, subhumeral lobes small ; densely and rather finely punctate, 

 punctures becoming smaller and seriate in arrangement posteriorly. 

 Apex of prostenmm widely rounded. Abdomen with the second 

 segment very narrow and the third and fourth just traceable across 

 middle. 



Length 2^ mm. 



$ . Differs in being entirely of a dingy flavous or testaceous — 

 except at the junction of the prothorax with the elytra and scutellum, 

 the metasternum, a subapical elytral fascia and the outer half of
