Australian and Tasmanian Cryptocephalides. 437 



Head with sparse and moderately large punctures ; feebly strigose 

 at base and sides of eyes. Antennse somewhat shorter than body, 

 second joint rather more than half the length of third, third and fifth 

 subequal. Prothorax densely and coarsely punctate, punctures 

 smaller and sparser on disc than elsewhere ; oblique impressions 

 moderate ; margins very narrow. Scutellum triangular, base feebly 

 notched. Elytra rather briefly oblong, subhumeral lobes not very 

 small ; densely and coarsely punctate, punctures becoming subseriate 

 in arrangement, with irregularly convex interstices posteriorly. 

 Pygidium densely and rather coarsely punctate and with a fairly 

 distinct median carina. Apex of prosternnm widely subtriangular. 

 Abdomen with the third and fourth segments strongly incurved to 

 and just traceable across middle, fifth with a very distinct and fairly 

 deep median impression. 



Length 2^ mm. 



$ . Differs in having the legs, except the coxae, entirely black and 

 only the anterior angles of the pronotum flavous ; the antennae are 

 shorter and thinner and the punctures sparser and smaller. Ab- 

 domen with fourth segment not traceable across middle ; fovea large, 

 slightly encroaching on third segment. 



Length 2J mm. 



Hab. W. Australia : Swan River (A. M. Lea). 



From the sides the apical impression of the abdomen in 

 the male appears to be margined by small tubercles, a 

 character which alone should distinguish it from the allied 

 species. In the only female I have seen the fourth seg- 

 ment appears to be very slightly sinuous, but this may be 

 accidental. 



The female (except that it is not entirely dark above) 

 is not unlike a small specimen of Lox. atramentarius, Chp., 

 but the scutellum is smaller and the punctures are differ- 

 ent. The male of Lox. obhtsus, Chp,, has coarser punctures, 

 longer scutellum and the body with a bluish gloss. 



LOXOPLEURUS MICROSCOPICUS, n. sp. 

 (Plate XXIV, fig. 91.) 



^ . Black ; sides of prothorax and of elytra, muzzle, middle and 

 front of prosternum, intercoxal process and apex of abdomen flavous ; 

 legs testaceous, tarsi infuscate ; four basal joints of antennae 

 testaceous, the rest infuscate. 



Head with large but rather sparse punctures. Antennae shorter 

 than the body, second joint more than half the length of third, third
