BV THOMAS G. SLOANE. 165 



Note. — I would delete from the genus, and from the Australian fauna, 

 Homothes emarginatus Chaudoir, which I have recognised from the description as 

 a species of Celebes and Borneo ; it requires a new genus.

HoiioTHE'-; ELEOAN.s Newuian. 



(?^ II. micans Germ.).) 

 ITob.— Brighton, Roseberry, Strahan (Simson. No. 2613); Waratah, Bruni 

 Is. (Lea). Common in S.E. Australia. 



HbMOTHES GUTTiFER Germar. 



iJ(j6.— Launccston, Brighton (Simson, No. 2964). Very widely distributed 

 on the mainland. 



Homothes sericeus Ericlison. 



(= n. jjarricollis Blackburn, = H. vicinus Sloane). I feel confident about 

 this synonym>-. 



Hab. — Strahan (Simson). Ranges from Sydney to Perth on the mainland. 



HoirnTirRs xiOEr;, sp. nov. 



Black, oiiaque; tibiae lurid. 



Depressed. 'Head convex (1.5 mm. across eyes), lightly obliquely narrcwed 

 behind eyes. Prothorax shagreened, wider than head, cordate (1.4 X 1.7 mm,), 

 widest and angulate at marginal seta, obliquely naiTowed to base; sides not situate 

 before base. Elytra oval (5 X 3.3 mm.), suljsinuate-truncate at apes, deeply 

 crenulate-striate; interstices opaque, shagreened, subeonvex, a little transversely 

 wrinkled, especially towards sides; third interstice 5-punctate. Length, 8.2, 

 breadth, 3.3 mm. 



Hab. — Cradle Mountain (Carter). Unique. 



A very distinct species differentiated from all others by colour coal-black; 

 femora black: elytra more strongly striate, etc. Its prothorax resembles that of 

 H. sericeus Erichs., but is wider, and the sides are obliquely angustate to the 

 base with a faint outward curve, not an inward curve as in H. sericeus. 



Tribe Ctenodactylini. 

 This tribe has not hitherto been recognised as entering the Australian fauna, 

 but Plagiotehim opalescens Ollifif, is certainly a member of it, as is also Plagio- 

 telnm iriiiiim Solier: these two species are. from comparison, truly congeneric
