of abdomen with very large, round, deep punctures or foveaj, 

 suture between 1st and 2nd deep at the sides but not traceable 

 across middle; intermediates each with a very feeble transverse 

 setose row of punctures. Length 4 J, rostrum 1^; width 2h mm. 

 Hab. — W.A. : Donnybrook. 



Allied to the following species but may be distinguished by its 

 larger abdominal fovese, larger punctures of rostrum and smaller 

 elytral punctures. 



Decilaus distans, Pasc; Mast. Cat. Sp. No. 5468. 

 (Acalles distans, Pasc.) 



Upper surface with a few whitish scales, not (to the naked eye) 

 affecting the general colour, except near apex of elytra where a 

 small distinct but somewhat irregular spot is condensed towards 

 each side. Coxaj and sterna rather densely squamose. Pectoral 

 canal with sparse setose scales. 



Head with large punctures between eyes, becoming much smaller 

 on vertex. Rostrum densely and strongly punctate, with or 

 without several irregular impunctate spaces, very feebly incurved 

 to middle. Scape shorter than funicle, inserted about two-fifths 

 from apex of rostrum and passing apex. Prothorax ti'ansverse, 

 apex not half the width of base; with large round punctures 

 smaller at apex and middle than elsewhere. Elytra subcordate, 

 wider than prothorax at base and widest just before middle; 

 striate-punctate, punctures large, elongate-oblong, open posteriorly; 

 interstices almost flat, considerably wider than punctures; densely 

 and minutely granulate, each granule punctate in the middle. Two 

 basal segments of abdomen with very large round and rather 

 shallow punctures or small foveje, suture between 1st and 2nd 

 deep at sides and sufficiently distinct across middle; intermediates 

 depressed posteriorly, each Avith a moderately distinct row of 

 squamose punctures. Length 3^, rostrum 1; width 2|^; variation 

 in length 3^-4|^ mm. 



Hab. — W.A. : Swan River, Rottnest Island.
