 front angles short, obtuse, and somewhat reflexed ; sides well rounded anteriorly, 

 contracted posteriorly, finely and equally bordered ; foliaceous sides rather narrow, 

 obsolete behind, not marked off from the disc by a depression ; disc smooth, median 

 line very faintly impressed, except at the base ; base much narrower than the apex, 

 a little sinuately truncated ; hind angles small but distinct, acute, outwardly directed ; 

 scutellum black, smooth, narrowly rounded behind : elytra oval, brassy-green, 

 brighter and clearer on the sides and epipleurse ; depressed behind the scutellum ; 

 shoulders narrow, very obliquely rounded ; on each elytron six rather fine sulci, which, 

 unite in pairs at the base, the outer one very faint and distinctly punctured, the others 

 fainter and punctate at base and apex ; sides and epipleursB nearly smooth ; intervals 

 not visibly punctured, unequal, 3 and 5 widest : under-side and legs shining black :

New Holland. 



An elegant little species, the jet black head and prothorax con- 

 trasting strongly with the more brightly coloured elytra. A single 

 example obtained from an old French collection and labelled "^J«Z«s 

 ceneus, Dej." 



Cabdiothorax distinctus, sp. n. 



<y . Elongate, slender, shining dark greenish-black, with faint purplish reflections 

 on the prothorax, sides, and epipleuree : prothorax ample, as wide across the middle 

 as the elytra ; apex ratlier feebly emarginate, finely bordered, front angles obtuse ; 

 sides well rounded anteriorly; base much narrower than apex, truncate; hind angles 

 prolonged backwards ; foliaceous sides moderate, widest at the middle (where they 

 equal about one-fifth the width of the disc), much narrowed behind ; disc smooth ; 

 median line very faintly impressed except at the base : elytra elongate-oval ; not 

 depressed behind the scutellum ; each elytron with six rather shallow feebly punctured 

 sulci, the two outer very faint ; intervals sub-equal ; sides and epipleurte nearly 

 smooth ; under-side and legs shining black ; tarsi rxifescent ; antennse fuscous ; legs 

 rather elongate ; hind tibiae a little flexuous. 



$ . More robust, the elytra more broadly oval, the legs shorter, the hind tibifB

Caediothobax ceenulicollis, sp. n. 



Black, glossy on the elytra : head broadly rounded in front ; a depression at 

 each side in front, and a large deep crescent-shaped depression between the eyes ; 

 prothorax ample, somewhat parabolically rounded at the sides ; base much narrower 

 than apex, and strongly bisinuate ; hind angles prominent and outwardly directed ; 

 apex deeply emarginate ; foliaceous sides well developed, broadest at the middle 

 (where they equal one-fifth the width of the disc), narrowest behind, separated from 

 the disc by a strong uninterrupted furrow ; lateral edges finely crenulated and dis- 

 tinctly reflexed ; disc very uneven ; median line deeply and broadly channelled ; at
