some of whicli, although they Avoiild be called " evidently 

 distinct," are apparently so nearly allied to others already 

 published that they could not be satisfactorily differentiated 

 without a larger suite of specimens than I possess. The varia- 

 bility of some of them (e. g. A. 2'>urpureus) has probably led 

 to more than one being split up into so-called species. All 

 here described are, I venture to think, either more or less 

 specialized or are distinguished by very strong characters 

 from those to which they may be considered most approxi- 

 mate. 



Amarygmus ccelestts. 



A. ovalis, niger, nitidus ; elj-tris Icete cyaneis, sat leviter seriatim 

 pimctatis, interstitiis impunctatis ; tarsis tenuiter elongatis. 



Hah. Brisbane. 



Moderately oval, black, shining ; the elytra bright indigo- 

 blue, with slight violet reflections ; head flat between the an- 

 tennary tubers, separated from the clypeus by a deep broad 

 groove ; eyes approximate, entirely concealed by the prothorax 

 in repose ; antennae rather slender, the last joint irregularly 

 oblong-obovate ; prothorax small, not very broad at the base 

 or apex, the punctures almost obsolete ; scutellum small, tri- 

 angular ; elytra moderately convex, seriate-punctate, the punc- 

 tures rather fine, but well-marked, intervals of the striae im- 

 punctate ; body beneath and legs glossy black, with a brownish 

 tinge ; abdomen finely striated longitudinally ; all the tarsi 

 slender, elongate. Length 5^ lines. 



A handsome species, allied to A. ametliystinuSj Fab.* ; the 

 latter, however, has a dark-blue prothorax and red femora. 



Amarygmus vinosus. 



A. ovalis, viridis, nitidus ; elytris purpureis in virides mutantibus, 

 sat leviter seriatim punctatis, interstitiis subtiliter punctatis. 



Hah. Sydney. 



Moderately oval, green, shining, the elytra purple changing 

 to green according to the light ; head black, very slightly 

 convex above the clypeus ; eyes moderately approximate ; 

 antennas gradually thicker outward, the last joint ovate ; pro- 

 thorax minutely and sparsely punctured, broad at the apex ; 

 scutellum small, triangular, black ; elytra moderately convex, 

 seriate-punctate, the punctures rather fine, but well marked, 

 the intervals of the rows minutely punctured ; body beneath 

 and legs glossy brownish black, the abdomen finely striated 

 longitudinally ; anterior and intermediate tarsi sliorter than in 

 the last. Length 5^ lines.
