234 NOTES ON SOME AUSTRALIAN TENEBRIOSIDAE, 



The sexual distinction is very similar hut less definite than is the ease with 

 C. walckenaerii. 



T y p e s in Coll. Carter. 



Cardiothoras metallicus, n.sp. fXext-fig. 5.) 



Elongate-oval; above metallic blue, sometimes with violet or brighter sheea 

 towards margins, underside black, antennae fuscous, tarsi clothed beneath with 

 red hair. Head finely punctate, frontal impression sharply angulate, a seta near 

 each angle on epistoma; a round fovea between eyes and a few foveate punctures 

 on forehead, antennal joints pear-shaped, 3rd much longer than 4th, and sub- 

 cylindrie, 11th half as long again as 10th, ovate-acuminate. I'rothorax 3^4 mm. 

 widest in front of middle, arcuate-emarginate at apex, base angulate and nar- 

 rowly marginal, sides moderately rounded, converging to base, anterior angles 

 rounded, posterior obtuse, undentate; lateral foliation narrow, without separating 

 sulcus, and bearing two or three setae ; disc with well marked medial sulcus, and 

 basal impression near angles, sometimes with a few shallow impressions on eacii 

 side of middle. Scutellum convex, elongate, rounded behind. Elytra rather nar- 

 rowly ovate, shoulders obsolete, epipleural fold very narrow, with 9 well-markeil 

 sulci on each (the 9th on the sides), intervals evenly convex, the first two and 

 sixth continuous to apex, 3rd joining 5th on declivity. Underside smooth; legs 

 without sexual charactei's. Dimensions : 13 — 14 ^ 4 — 4J mm. 



Hah. — Bunya Jlouiitains, S. Queensland (INIrs. Ilobler. Jlr R. Illidge and 

 H. .7. Carter)." 



Twenty specimens taken by the author, besides those taken by the shove, 

 during a cainp of the Royal Austsalasian Ornithologists' Union. The species ea!i 

 only lie confused with C. coeruleo-niger Cart., which, however, has a truncate base 

 to the prothorax, with dentate posterior angles, each elytron with only five ciearly 

 defined sulci inter alia. 



Types in Coll. Carter. 



Cardiothorax regularis, n.sp. (Test-fig. 6.) 

 Elongate-ovate, opaque brown-black, antennae and tarsi brown, legs and 

 underside nitid black. Head with epistoma rather sharply produced in front, witfi 

 rhomboidal frontal impression; antennae having joint 3 half as long again as 4. 

 Prothorax arcuate-emarginate at apex, feebly arcuate at base, anterior angles 

 rounded, sides well rounded at middle; posterior angles narrowly dentate, with a 

 small blunt tooth directed downwards and outwards; foliate margins horizontal 

 with narrow nitid border throughout; disc rather flat, with a medial sulcus, two 

 small foveae on each lobe (more or less connected by a depressed line), and a 

 wide depression between disc and foliate margins. Scutellum oval. Elytra sul- 

 cate, with nine regular convex intervals, the lateral three narrow: epipleurae and 

 underside .smooth. Dimensions: 15 — 17 X 5 — 5i mm. 



Hah. — Toronto (Lake Macquarie), 00 miles N. of Sydney (Mr. Deu(iuet). 

 Five specimens examined — showing no marked sexual distinction — of a species 

 very near C. altrrnatu>< mihi Imt clearly differentiated as follows: — - 

 renii/iiris. aUernatm. 



Head. Narrower and more pointed. Wider and squarer. 



.intciiinic. More slender. Stouter. 



Prol/uiyax. Anterior angles rounded. .-Xnterior angles sub-acute. 



Posterior tooth narrow. Posterior tooth wide. 



/ilvlid. Intervals* sub-equal. 1st, 3rd & iith evidently wider than rest.
