SCYDMAEMUAE. 



Scydmaenus r/ientulus, n.sp. 



Dark reddish — or brownish — castaneous, under surface darker, 

 appendages somewhat flavous. Clothed with rather sparse, 

 straggling hair, or fine setae, but becoming fairly dense on 

 sides of prothorax. 



Head smooth, with small prominent eyes. Antennae just 

 passing base of prothorax ; with a distinct four-jointed club, 

 which is about equal in length to the six preceding joints com- 

 bined. ProtJiorar slightly longer than wide, apex and apical 

 sides rounded, base scarcely narrower than greatest width ; 

 with four deep l)asal punctures, and a slightly oljlique longi- 

 tudinal impression on each side towards base. Elytra oblong- 

 ovate, siomewhat flattened, sides gently rounded, with a shallow 

 depression on each side of base ; with sparse, indistinct punc- 

 tures. Front tibiae rather strongly inflated to apex. Length 

 1 mm. 



Hab. — -Tasmania : Burnie, in a nest of a small variety of 

 Ectatomrna metallicum amongst stones close to sea beach (A. 

 M. Lea). 



The front tibiae are dilated somewhat as in gulosus (this, 

 however, appears to be a masculine character only), but the 

 elytra and antennae are darker, and the antennae are some- 

 what shorter. The whole upper surface is of an almost uniform 

 shade of colour. 



Scydmaemis coJohnpsix, n.sp. 



Reddish-castaneous, appendages, paler. Clothed with pale 

 and rather sparse, straggling hair or fine setae, becoming dense 

 on sides of prothorax, and almost or quite absent from its disc. 



Head and antennae as described in preceding species. Pro- 

 thorax scarcely longer than wide, outlines much as in preceding 

 species, base with four deep punctures, feebly connected by a 

 shallow transverse impression, which on each side becomes a 

 short deep groove. Elytra depressed, oblong ovate, sides gently 

 and regularly rounded ; basal impressions feeble ; with sparse 

 indistinct punctures. Front tibiae in one sex rather strongly 

 inflated to apex. Length 1 mm.
