•wider than prothorax, considerably wider about the middle : 

 striate-punctate, punctures comparatively small; interstices much 

 wider than punctures, each with a distinct row of small punctate 

 and rather distant granules. Abdomen as in two preceding species. 

 Length 4^, rostrum 1;^; width 2§; variation in length 3^-6 1 mm. 



£l(ib. — W.A.: Geraldton and Swan River. 



This species is exceedingly abundant under a spiny thick-leaved 

 beach-growing plant about Geraldton ; at Fremantle I have 

 only taken three specimens. It may be distinguished from the 

 preceding by its much paler scales, wider elytra, denser prothoracic 

 punctures and more regular elytral granules ; these in fresh 

 specimens are very distinct and cause the elytra to appear regu- 

 larly dotted with small black spots; in old or abraded specimens, 

 however, they are less distinct. From nquamosus it ma}" be 

 distinguised by its much wider elytra, carinate head, &c. 



Decilaus xanthorrhoe^, n.sp. 



Head feebly, the prothorax very feebly squamose; elytra rather 

 densely squamose, the scales mostly black but with small spots of 

 whitish scales irregularly distributed and more numerous towards 

 apex than base. Under surface (except apical segment of abdomen 

 where they are dense) with sparse greyish scales; legs with rather 

 long white scales, femora feebly ringed. Pectoral canal not 

 scaly. 



Read depressed and with moderately strong punctures between 

 eyes, becoming very small on vertex. Rostrum shining, feebly 

 punctate, feebly but regularly and distinctly dilating to base and 

 apex. Scape long, but shorter than funicle, inserted about two- 

 fifths from apex of rostrum and passing apex. Prothorax slightly 

 transverse, apical third not half the width of base; with dense, 

 large, round, deep punctures. Scutellum present, but small and 

 indistinct. Elytra subcordate, wider than prothorax at base and 

 widest at about one-third their length from base; striate-punctate, 

 punctures large, oblong, contiguous; interstices rather strongly 

 convex and varying from a little narrower to a little wider than 

 punctures ; 9th interstice wide, flat, shining, impunctate and
