BY THOMAS G. SLOANE. 363 



Differs from T. bnprestioides by its smaller size, by the absence 

 of the post-humeral maculse of the elytra, and by the fifth stria 

 not reaching the base. It is closely allied to T. bipustulatus^ 

 Macl., from which it differs by having six (not five) strias on each 

 elytron and the striae reaching nearer the base — especially the 

 three inner ones. 



Tachys striolatus, Macleay. 



T. (Bembidiu/n) striolatus, Macl., has been redescribed and 

 placed in Tacliys by the Rev. Thos. Blackburn.* 



Habits : — Riparian, running beside the margins of streams, or 

 on sandy mai'gins of pools, during summer months. 



Hab. : Queensland — Gayndah (Masters); N.S.Wales — Narran- 

 dera and Mulwala (Sloane); Victoria — near Bright (Blackburn). 



Tachys bipustulatus, Macleay. 



T. {Bembidiuin) bipustulatus, Macl., agrees in all points of 

 structural detail and in striation of elytra with T. striolatus, 

 Macl. 



Habits : — Riparian ; two specimens occurred to me on the 

 muddy edge of pools in Houlaghan's Creek near Junee. 



Hab. : Queensland — Gayndah (Masters); IST.S. Wales — Forest 

 Reefs (Lea), Junee District (Sloane). 



Tachys curticollis, n.sp. 



Oval, convex. Prothorax transverse, evidently a little wider 

 across base than apex, posterior angles rectangular and acute; 

 elytra levigate on disc, bistriate on each side of suture, lightly 

 bipunctate near second stria. Black, or piceous black ; each 

 elytron with a dull reddish spot near shoulder and another at 

 beginning of apical declivity; legs pale testaceous.
