})uuctiircd ; body beneath, legs, and antenna? jet-black, glossy, 

 abdomen finely punctured. Length 6-7 lines. 



A very variable species as to the colour of its elytra, but 

 readily distinguished, except from the next, by the fineness of 

 its seriated punctures, which are scarcely to be discriminated 

 from the interstitial punctures, together with its greater breadth 

 and convexity. A. Ilowittii is a still broader species, with its 

 dark-green colour varying principally from darker to lighter 

 shades. 



Amarygmus Howittii. 



A. late ovalis, nitidus ; prothoraco nigro ; elytris subtiliter seriatim 

 punctatis, interstitiis subtilissime punctatis, xneo et cuprco vcrsi- 

 coloribus. 



Hah, Victoria. 



Broadly oval, smooth, shining; head glossy black; eyes 

 not approximate ; clypeus rather narrow ; antenna? black, ex- 

 tending but little beyond the prothorax, thicker outwards, the 

 last four joints shorter than the preceding, opaque, the rest 

 glossy ; prothorax small, broad at the base, the apex narrow, 

 the anterior angles not produced, glossy black, finely and 

 rather remotely punctured ; scutellum small, triangular, black; 

 elytra rather strongly convex, the sides nearly parallel or but 

 very slightly rounded, very finely seriate-punctate, the punc- 

 tures very close, the intervals of the rows wide and veiy 

 minutely punctured, the colour dark greenish, shaded from 

 brassy to copper according to the light ; body beneath . and 

 legs jet-black and very glossy. Length 7 lines. 



Dr. Howitt says of this very distinct species, " common 

 everywhere ;" but the two specimens he has sent me are the 

 only ones I have seen. It approaches the following in outline, 

 but is very different in colour and sculpture. 



Amarygmus semiticus. 



A. late obovatus, subnitidus, flavo-cuprcus ; elytris subtiliter seriatim 

 punctatis, interstitiis vage ct subtilissime punctatis ; corpore sub- 

 tus viridi-nigro. 



Hah. Port Denison. 



Broadly obovate, slightly nitid, colour above an unvarying 

 yellowish copper; head black; eyes approximate; clypeus rather 

 naiTOw; antennas black, thicker outwards, fourth and succeeding 

 joints of nearly equal length, the third not much longer than the 

 fourth ; prothorax much narrower at the apex, anterior angles 

 somewhat produced, very minutely punctured ; scutellum small, 

 curvilinearly triangular, black ; elytra broadest nearly at the
