And rat kin. and Tasnianlan Coleoptera. 185 



Hab. — Tasmania : Parattali, in a nest of Colobopsls yasseri 

 (A. M. Lea). 



A short, pale, highly polished species. 



Sri/dtiKif'inix /nirroj/s, n.sp. (Fig. 10.) 



Pale reddish castaneous, appendages slightly paler, some- 

 what infuseated at junction of prothorax and elytra. Elytra 

 with sparse and very short pubescence, rest of upper surface 

 with somewhat longer clothing. 



Head smooth, regularly dilated from a strong basal con- 

 striction to between antennae ; eyes minute and invisible from 

 above. Antennae thin, none of the joints ti'ansverse, distinctly 

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

 the joints of which are much thinner than usual. Prothorax 

 longer than wide, sides distinctly rounded, and widest slightly 

 nearer apex than base ; base with four distinct punctures. 

 Elytra oblong-ovate, at base scarcely wider than base of pro- 

 thorax, but at widest (just beyond the middle) about twice as 

 wide; basal impressions feeble; punctures rather sparse and 

 indistinct. Leys long ; femora clavate. Length 1^ mm. 



Hah. — W. Australia : Swan River, in a nest of Pwuera hitea 

 (A. M. Lea). 



Readily distinguished from all previously described Aus- 

 tralian species by the shape of its head, small eyes and thin 

 antennae. The second joint of the antennae is as long as the 

 third and fourth combined, but this proportion is much as in 

 all the preceding species. In size and appearance, except for 

 shape of head, much like optatux, but the clulj also is very 

 different. Both front tibiae and tarsi are missing in the type. 



Sryd mac till >i su/i /jI irirorii /■'<, n.s)). 



Deep shining black, antennae, abdomen and base of femora 

 piceous, or diluted in parts with red, palpi and tarsi flavous. 

 With rather sparse pale pubescence. 



JJ (ad transverse; eyes suuill and fairly prominent; clypeal 

 sutures distinct. Antennae long and thin, fully four of their 

 joints passing base of prothorax, not clubbed, first joint partly 

 concealed from above, almost as long as second and third com-
