162 NOTES ON AUSTRALIAN COLEOPTERA, 



with nine sulci, the fifth interval rather wider and more raised — 

 especially at base — than the others. Epipleune and abdomen 

 smooth ; legs thin, fore-tibiae slightly curved. Dimensions : 

 15x5 mm. 



Hah. — Townsville, Q. (Ejnar Fischer). 



Two specimens, sent by Mr. Kershaw, after whom I name it, 

 show no sexual distinctions and belong to a species intermediate 

 between C. encephalus Pasc, and C. rotundicollis Cart. It can 

 be distinguished from both by its narrow, subcordate prothorax, 

 with thickened lateral border and posterior tooth directed back- 

 ward. In both the other species this tooth is twisted outwards. 

 In colour, and form of prothorax, there is a likeness to C. cordi- 

 collis Pasc, but it is smaller and narrower than Pascoe's species, 

 and has, moreover, acute anterior angles (rounded in C.cordicollis). 



Type in the National Museum, Melbourne. 



Cardiothorax macleayensis, n.sp. (Plate v., fig.< s ). 



Elongate-elliptic, brilliant violet-bronze, antenna? and tarsi 

 reddish-brown, underside and legs black. 



Head with scattered punctures on frontal area. Prothorax 

 subcordate, widest before middle, little convex, finely bordered 

 at base, apical border obsolete in middle, anterior angles pro- 

 minent but wide; sides widely rounded on anterior half, con 

 tracted at base; the dentate hind angles small and outwardly 

 directed, base truncate; foliaceous margins wide and separated 

 from disc by strong sulcus; disc smooth, medial sulcus well 

 marked throughout, a triangular depression near hind angles, 

 and (in general) one foveate puncture on each side of medial 

 sulcus. Scutellum small, oval. Elytra wider than prothorax at 

 base, elliptic, shoulders very obtusely rounded ; sulcate, each 

 with five well marked sulci and a sixth (external) faintly marked; 

 intervals regular, convex, not connected and obsolescent at apex, 

 sides, epipleurse, and underside smooth; legs thin, without any 

 sexual distinction, tibia' not thickened at apex. Dimensions: 

 15 x 5 J mm. 



ffab. — Macleay River, N.S.W. (S. Jackson).
