Widely spread in Eastern Australia, and also oecuning in Tasmania. It is 

 usually found in very damp situations under stones or drift, but Mr. II. J. 

 Carter finds it commonly in tussocks of grass in his grounds at Wahroonga, near 

 Sydney. It is a species of Motschulsky's genus Elaphropus, which has the 

 claws of the tarsi minutely sen'ulate (as recorded by Motschulsky and 6. H. 

 Horn). I do not recognise Elaphrupu)< as of more than subgeneric rank. In 

 this group (which is numerously represented in the Oriental Region) only one 

 diseal non-setiferous puncture occurs on the disc of the elytra, behind the 

 middle, at the position of the third interstice; there is, also, a puncture at the 

 inside of the apical stride far back from its anterior extremity, but no setiferous 

 ]>ore high up on tlie apical declivity. 



Tachys blackburni, n.sp. 



Oval, convex. Black; legs testaceous; antennae infuscate, with basal joint 

 testaceous. 



Head convex; front lightly bi-impressed, impressions short, wide apart, 

 l^rothorax small, laevigate, widest a little before middle; sides rounded anteriorly, 

 lightly suhsinuately narrowed to base; basal angles rectangular, not prominent; 

 base bifoveate; a light transverse impression between basal foveae. Elj'tra oval, 

 rather convex, bistriate on each side of suture; first stria well marked, entire, 

 punctate on disc, simple towards apex, second stria only present on disc, punctate, 

 eighth stria obsolete on middle of sides, distinct towards apex; apical stride well 

 developed; marginal channel distinctly punctate on middle of sides; disc bipunc- 

 tate outside second stria. Lengfh, 2 ; lircadth, 0.75 imii. 



liab. — Victoria: Beaconslield ("in muss,"' Wilson), Mooroolbark (under a 

 stick in a muddy place, Sloane). 



A distinct species resembling T. olliffi SI., and T. habitans SI., hut with 

 elytra only bistriate, it is more allied to T. carinulatus SI. 



Taciivs australicus Sloane (189(5). 



I lab. — Eastern coastal districts from Cooktown to Sydney; found in very 

 damp situations beside fresh water marshes and pools under drift or debris. 



Note. — In thi; description of T. australicus, 1 have said the elytra are with- 

 out discoidal punctures, but this is erroneous, two flue punctures are present on 

 the disc at position of tliird interstice; the elytra have only the two inner striae 

 present. 



Tachys doddi Sloane (1903). 



Ilab. — Queensland: Townsville (Dodd); Victoria: Lakes Entrance (Wil- 

 son). Common on sandy margins of tidal lagoons near Townsville. 



Note.—l have in my collection a Malayan species which cannot be differen- 

 tiated fi-om T. doddi, though the basal angles of the prothorax are a little less 

 acute; it seems to vary a good deal in size, and may be conspeeific with Putzey's 

 T. plar/iatus, or his T. pictipennis, which may be forms of one species, but I 

 liave not felt able to be certain on this point. Length, 2.5 — 3 mm. 



J/ab.— Philippines, Celebes, Sumbawa.
