Austndidn (ind Tasmanian Coleopteva. 167 



Head short, Hat, densely punctate and without longitudinal 

 ini]iression. Antennae short wide and flat, about as long as 

 head, narrow at base, then strongly inflated, and then feebly 

 diminishing in width to apex, widest portion with a feeble im- 

 pression in middle. Froihorar widest at apical third, where 

 the width is almost twice as great as the length, with a feeble 

 medio-basal impression, punctures as on head. Elytra w^ith 

 dense punctures, rather sparser on disc than elsewhere, sutural 

 stria distinct. Ahdoinfii with basal fovea strongly transverse, 

 and not encroaching on second segment, its sides parallel, near 

 each side with a feebly elevated ridge almost parallel with the 

 margin and behind the fovea becoming narrower and more 

 distinct; under surface largely excavated, each side of middle 

 of fourth segment with a small acute tooth, similar but smaller 

 teeth on first, middle of fifth with a loose facicle. Metasternum 

 obtusely ridged along middle, the ridge terminating in a feeble 

 tooth. Femora fairly stout ; tibiae inflated towards apex, the 

 middle pair strongly mucronate at apex. Length If — 2 mm. 



? . Differs in having under surface of abdomen simple, meta- 

 sternum edentate, less convex along middle and the middle 

 tibiae not mucronate.

Seen from behind and the side each antenna appears to be 

 placed in the middle of a semicircular emargination, to be thin 

 with the apical third suddenly thickened. The apex itself is 

 somewhat oval in outline. From some directions the sides of 

 the protliorax appear to be obtusely produced at the apical 

 third, with the produced portion obtusely serrated,

<?. Reddish castaneous, greater portion of each elytron some- 

 what paler. Clothed with fine depressed setae, but becoming 

 longer and denser at apex of elytra ; abdomen with fine more 

 or less erect setae, and fasciculate on each side of base. 



Head short, flat, densely punctate and without longitudinal 

 impression. Antennae slightly longer than head, wide and 

 flat, base narrow, then strongly inflated to middle, and thence 

 very feebly diminishing in width to apex. FrothorOnV about
