Lea — On Australian Coleoptera 279 



Two other specimens from Dalliy ( Queensland 1 combine the small size of 

 var. 1, with the denser clothing of var. 2. 



LIMNICHUS CASTANEUS sp. nov. 



Castaneous. antennae palpi and tarsi iTavous. Rather densely clothed with 

 short, pale, sub-depressed pubescence. 



Head with dense, small punctures. Antennae rather long and thin. 

 Protluira.v about four times as wide as long, sides strongly rounded and much 

 wider at base than at apex, base with a scntellar lobe but otherwise almost 

 straight : punctures much as on head. Sciitclluiii narrow, highly polished and 

 impunctate. P.Iytra with sides gently rounded and continuous with those of 

 prothorax ; punctures about base less crowded than on prothorax, and slightly 

 larger, elsewhere smaller and less crowded. Vitdcr-surface with crowded and 

 small punctures, less distinct on middle of metasternum than elsewhere. 

 Length, 2 -75 — 3 ■25 mm. 



Hab. Queensland: Mount Tambourine (A. M. Lea), Cairns district ( F, P. 

 Dodd), Type. I. 10714. 



An oblong-elliptic species, with elytra about six times the length of 

 prothorax, and imusually narrow scutellum ; some specimens are darker than 

 others, and the abdomen is usually paler than the rest of the under surface, 



LIMNICHUS ATER sp. nov. 



Black, pal])i and ])arts of antennae and of legs more or less reddish. 

 I\Ioderately ckithed with ashen puljescence of two kinds: short and depressed, 

 and slightly longer and semi-erect ; under-surface with dense, depressed 

 pubescence. 



Head with rather small and crowded punctures. Eyes prominent. Antennae 

 thin. Prothorax more than thrice as wide as long, strongly convex in front, 

 sides finely margined and much wider at liase than at apex, middle with an obtuse 

 scutellar lobe, hind angles acute; punctures rather dense and small, becoming 

 subasperate at sides and apex, Scntrlhiiii rather short and triangular. Elytra 

 almost parallel-sided to beyond the middle, outlines subcontinuous with those of 

 prothorax : with dense and small punctures. Undcr-surface with crowded and 

 small punctures. Lc(is long and thin. Length, 2 '5 — 2 '75 mm. 



Hab. Northern Queensland (Blackburn's collection). Type, L 10715. 



About the size and with outlines much as in Liiniiichiis castaneiis. but darker, 

 eyes more pniminent. sinuation of base of elytra more jjronounced (although 

 much less than in Priiiodcs f'ltiictif^ciiiiis ) . and clothing different. ( )n abrasion 

 ihe prothorax and elytra are seen to have larger, but still small, jiunctures, 

 scattered amongst the others, but they are not seriate in arrangement.
