204 Arthur M. Lea : 



The flavous portion of the elytra varies from about one-fifth to 

 about one-third; although very distinct, it is not sharply limited. 

 The prothoracic foveae from some directions appear to be con- 

 nected by a strong transverse impression ; from other directions, 

 however, the impression seems rather feeble, although it is always 

 traceable. 



Numerous specimens differ in having the head and protliorax 

 almost or quite black, and such specimens sometimes have tlie 

 apex of elytra scarcely flavous; but, as I can find no differences in 

 clothing or structure, I presume they represent varieties only. 

 They are coloured much as ne.miniger , except that the under sur- 

 face is not dark; but their size is very slightly, although consis- 

 tently, smaller than that of that species, and are also somewhat 

 narrower. 



Scydtyiaenus flauipes, n.sp. 



Bright castaneous ; elytra (suture excepted) somewhat paler ; legs 

 and palpi flavous. Clothing as in two preceding species. 



Head (excluding neck) almost as long as wide, bilobed between 

 antennae. Eyes small and moderately prominent. Antennae long 

 and thin; club conspicuously four-jointed. Prothorai slightly longer 

 than wide; depressed; base with two small deep foveae. with a 

 conspicuous connecting impression. Elytra fiat and comparatively 

 narrow; widest about, middle ; basal impressions rather small. 

 Legs long; hind coxae moderately separated. Length 1^ mm. 



Hah. — W. Australia : Swan River. (A. M. Lea.) 



A small, depressed species, narrower thau most of those having 

 glabrous elytra. Except for the glabrous elytra, which, however, 

 are rather wider, it is much like atroph'us. 



Scydmaetius si/hr/labrij)e/i/i/s, n.sp. 



Castaneous. elytra (suture excepted) somewhat i>alef : legs and 

 palpi flavous. Upper surface glal)r(ius. cxrcpt toi' numerous 

 stramineous hairs at sides of protliorax, a few ahout Ijase (including 

 sides) of elytra, a few at sides of head, and a fascii'le on each side 

 of its base. 



//ead moderately transverse, rather strongly rounded between 

 antennae. Eyes (foi- the genus) lather large. Antennae rather 

 long and thin; club four-jointed. I'rotliora.c al)out as long as 

 wide, moderately convex; base Avith two small deep foveae. Elytra 

 rather short and wide; at base distinctly wider than prothorax,
