Head with dense and round but (for the genus) small 

 punctures. Rostrum densely punctate between antennae and 

 apex, without distinct punctures behind antennas, but with 

 five very distinct carinas, the median one of which is perfectly 

 straight, but the others slightly waved. Prothorax with dense, 

 short, shining ridges of unequal lengths; the sides punctate. 

 Elytra, subcordate, base almost perfectly straight, sides scarcely 

 inflated behind shoulders ; punctate-striate, the striae wide and 

 rather shallow, the punctures (except towards sides, where they 

 are rather large) small, distant, and comparatively indistinct \ 

 interstices feebly shining and with small (almost seriate) punc- 

 tures, the second and fourth not quite continuous to base, but 

 the second feebly raised near base and the fourth very dis- 

 tinctly raised about summit of posterior declivity, the others 

 there being but little raised ; declivity itself abrupt and almost 

 inwardly oblique. Sterna irregularly and not coarsely punc- 

 tate. Mesosternal receptacle with very thin walls. Two basal 

 segments of abdomen with (for the genus) small and not at 

 all foveate punctures, those on the second in two very irregular 

 series. Legs (especially the posterior) longer and thinner than 

 usual ; femora edentate, with shallow punctures, the posterior 

 strongly arcuate; tibiae with eight distinct grooves, with a 

 feeble subapical tooth below but a very distinct one above, 

 posterior very decidedly curved both longitudinally and out- 

 wardly; third tarsal joint wider than second and rather deeply 

 bilobed. Length, 1\ mm. ; rostrum, 2J mm. ; width, 5 mm. 



Hab. — Northern Territory: Port Darwin (type in 

 Macleay Museum). 



A remarkable species : the elytra without granules, the 

 fourth interstice very decidedly raised, the posterior declivity 

 very abrupt, the punctures of the two basal segments of abdo- 

 men comparatively small, long and crooked hindlegs, etc. Only 

 the sides of the prothorax are distinctly punctate, the disc 

 being covered with numerous short shining ridges of unequal 

 lengths (becoming granules towards apex), but with a more 

 or less inwardly oblique trend, the whole being reminiscent 

 of N eomelanterius carinicollis . The length given is that of a 

 straight line from apex of prothorax to apex of elytra, but 

 along the curve of the back the distance between the same 

 points is 13 \ mm. 



Anilaus costirostris, n. sp. 



& • Reddish-brown, antennae and tarsi paler. Moder- 

 ately densely and uniformly clothed with short, stout scales, 

 interspersed with longer and suberect ones, varying from 

 dingy-grey to sooty, but giving the surface a dingy-brown 

 appearance.
