parallel-sided for three-fourth of the length, and rounded at the 

 posterior angles, with the base much narrowed and shortly lobed, 

 the median line is strongly marked from near the apex, and there 

 is a very marked depression near the base at the posterior angles. 

 Elytra narrower than the thorax and twice the length, slightly 

 narrower at the base than behind, depressed a little on the suture, 

 rather faintly but distinctly striate-punctate with an impressed 

 punctui-e near each shoulder, another towards the apex, and a 

 regular series of strong punctures in the lateral margins. Beneath 

 black, the anterior tibiae very strongly bidentate externally. 



Long. 9 lines, lat. 2| lines. 



This insect has much the appearance of an Eutoma, but the less 

 securiform palpi, the short moniliform antennae, and less notched 

 anterior femora seem to mark its approach to the next group 

 which I have named Carenoscaphits. In fact the resemblance to 

 C. quadripunctatus, Macl., is very striking. 



57. Calliscapterus viRiDiiENEUS, n.sp. 



Oblong-oval, brilliant metallic green on the upper surface with 

 a purplish tinge on the apex of the thorax, and the sides and disk 

 of the elytra. Head large, transverse, the frontal grooves 

 diverging a little behind. Thorax transverse, wider than the head, 

 the anterior angles prominent, the lateral margins reflected and 

 narrowed to a short lobe at the base, the basal impression on each 

 side shallovv, and the median canal deep. Elytra shortly oval, about 

 the width of the thorax at the widest part and about twice its 

 length, faintly striate-punctate, the base a little emarginate and 

 punctate, the humeral angles thick, prominent and a little 

 recurved, the disk flattish, the lateral margins with a row of deep 

 punctures and a large puncture on each elytron about the apical 

 fourth. Beneath black, the anterior tibiae tridentate externally. 



Long. 5\ lines, lat. 2^ lines. 



Except for its much smaller size and acutely shouldered 

 elytra, this species might almost be taken for C. coruscus, Macl., 

 a species from some part of Northern Australia, and unique in my 

 collection.
