348 Mr. F. P. Pascoe on new Genera and SjJecies of 



Amarygmus obtusus. 



A. oblongo-subovalis, niger, nitidus ; elytris fusco-purpureis, hand 

 versicoloribus, fortiter seriatim punctatis ; tarsis subtus longe 

 pilosis. 



Hah. Queensland. 



Oblong-suboval, black, shining, the elytra dark purple- 

 brown without reflections ; head slightly concave above the 

 clypeus ; eyes approximate ; antennas short, slender, the last 

 four joints with a brownish pubescence, the last shortly ovate ; 

 prothorax short, gradually rounded from the base, broad and 

 obtuse anteriorly, minutely punctured ; scutellum triangular, 

 black ; elytra rather elongate, convex, the sides very slightly 

 rounded, seriate-punctate, the punctures rather coarse, the in- 

 tervals of the rows almost obsoletely punctured ; body beneath 

 and legs brownish black, subnitid j tarsi slender, with long 

 hairs beneath. Length 7 lines. 



The form and colour of this very distinct species will render 

 it easily recognizable. 



Amarygmus polychromus. 



A. late ovalis, niger, nitidus ; elytris cyaneis, vel purpureis, vel 

 viridibus, coloribus variis resplendentibus, tenuissiine seriatim 

 punctatis ; prothorace basi haud lato. 



Hah. South Australia. 



Broadly oval, black, shining; the elytra blue, purple, or 

 green, with metallic reflections of various colours ; head very 

 slightly convex in front ; eyes moderately approximate ; an- 

 tennas rather slender, last joint elongate-ovate ; prothorax 

 black, with greenish reflections, not broad at the base, narrow 

 at the apex, minutely and sparsely punctured ; scutellum equi- 

 laterally triangular ; elytra rather strongly convex, very finely 

 seriate-punctate, the intervals of the rows broad and minutely 

 punctured ; body beneath, legs, and antennas 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. Howittii is a still broader species, with its 

 dark-green colour varying principally from darker to lighter 

 shades. 



Amarygmus Howittii. 



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