SUBFAMILY LEPTOPSIDES. 



Onesorus squamosus, n. sp. 



Black, densely clothed with soft, pale-brown, round 

 scales; interspersed with fine setae. 



Head with small dense concealed punctures; inter-ocular 

 fovea minute. Eyes narrowly ovate, finely faceted. Ros- 

 trum stout, not much shorter than prothorax, rather strongly 

 dilated at apex; with a strong central carina, but rest of 

 sculpture hidden. Scape about half the length of funicle, 

 the latter with first joint slightly longer than third, but 

 distinctly shorter than second. Prothorax moderately trans- 

 verse, sides strongly rounded, base and apex almost equal; 

 ocular lobes strong and rounded; with large, deep punctures 

 or foveas occupying most of the surface. Scutellum distinct. 

 Elytra very briefly ovate or subcordate, much wider than 

 prothorax, sides strongly and regularly rounded; with regu- 

 lar rows of very large, partially concealed punctures; inter- 

 stices regularly convex. Legs rather robust; tibiae apparently 

 not denticulate below. Length (excluding rostrum), 10|-11 

 mm. 



//a6.— North- Western Australia: Onslow (C. French). 



The scales are almost uniformly distributed, but are 

 slightly paler on the under surface and legs than elsewhere; 

 they are almost perfectly circular, very closely applied to 

 derm, and have a peculiar velvety appearance. The setae, 

 especially on the elytra, are very fine and hair-like. The 

 triangular apical plate is almost hidden by setae, as in the 

 description of Obesus, but that species (amongst other dis- 

 crepancies) is said to have three sordid ochraceous vittse on 

 the prothorax. 



Some specimens in the Macleay Museum have the cloth- 

 ing almost white. 



Catastygnus densus, n. sp. 

 Reddish-brown or black. Densely and almost uniformly 

 covered with scales of a very light-brown colour, but in places
