tinct puncture near inner side of apical striole far back. Length, 2.6; breadth, 

 1.2 mm. 



Uab. — Victoria: Belgrave (Wilson), Mountains of Upper Yarra (Fischer). 

 I owe a specimen to the kindness of Mr. Fischer. Colls. Wilson, Fischer, and 

 Sloane. 



It is probably allied to T. baldieiisis Blackb., which is unknown to me in 

 nature, but is smaller, and does not agree with the description of that species; 

 for one thing, tlie striae are not on the disc "erassissime punctulalis." The male 

 has one setigerous fovea on each side of the apex of the abdomen; Hlackburn 

 has noted that T. baldietisis ? has two large setiferous punctures on each side. 

 The anterior tarsi have the two basal joints dilatate, the posterior tarsi are 

 shorter than usual in the genus, first joint not as long as three succeeding joints 

 together, hardly as long as fifth. 



Tachys carinulatus, n.sp. 



?. Robust, oval. Prothorax transverse, decidedly narrowed to ba.se, a 

 short submarginal carina near each basal angle; elytra bistriate on disc, bipunc- 

 tate on disc at position of third interstice, eighth stria obsolete on basal half, 

 apical striole short, distinct. Piceous, apical declivity and posterior part of 

 lateral declivities of a more or less dull I'errugiuous colour; antennae fuscous, 

 basal joint and leg-s testaceous. 



Head laevigate; front lightly and shortly bi-impressed. Prothorax hroader 

 than long, a little wider at base than apex; base truncate, angles rectang-ular ; 

 a transverse stria near base. Elytra oval, much wider than prothorax; first 

 stria fine, but well marked, a little punctate, second very faint; border wide, 

 reflexed; a puncture beside inner side of apical striole far back, space between 

 apical striole and eightli stria narrow, carinate. Length, 2; Itreadth, 1.1 mm. 



Hab. — Victorian Alps (Hospice, Mt. St. Bernard, Davey). 



I owe a single specimen of this species to the kindness of Mr. H. W. Davey; 

 it is a distinct species, in some ways resembling T. mulivalensis SI., but with a 

 submarginal basal carina on each side of prothorax as in T. atridermis SI., be- 

 side which 1 have placed it in the table above; from T. atridermis it is readily 

 differentiated by size smaller; form less convex; front less strongly bi-impressed; 

 elytra much less strongly striate on disc, eighth stria not entire. 



Tachys mitchelli Sloane (1894). 



Hab. — N.S. Wales: Urana and Muhvala (Sloane); Victoria: Sea Lake 

 (Goudie). Found beside fresh water marshes in muddy situations under logs and 

 debris. 



Tachys mulwalensis Sloane (1899). 



Ilab. — Murray River, Mulwala and Albury (Sloane); Melbourne (Fischer). 



Length, 3 mm. (Melbourne specimens, 2.5 mm.), d with basal joint of an- 

 terior tarsi wide. 



In my description the length was erroneously given as 2 mm. ; a re- 

 measurement of the type specimens shows the correct length to be 3 mm. I 

 obtained this species in great numbers under the bark of redgum trees standing 

 in the flood waters of the Murray River; specimens were also found in the 

 debris washed up by flood waters at Albury. Mr. Ejnar Fischer has sent me 

 very dark coloured specimens from Melbourne, with the information that he 

 finds it not uuconnuon under the bark of trees.
