348 Mr. F. P. Pascoe 07i new Genera and Species of 



Amarygmus ohtusus. 



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

 versicoloribus, fortiter seriatim punctatis ; tarsis siibtus longe 

 pilosis. 



Hah. Queensland. 



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

 brown without reflections; head slightly concave above the 

 clypeus ; eyes approximate ; antennse 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 ; tarsi slender, with long 

 hairs beneath. Length 7 lines. 



The form and colour of this very distinct species will render 

 it easily recognizable. 



Amarygmus polycliromiis. 



A. late ovaHs, niger, nitidus ; elytris cyaneis, vel purpureis, yel 

 viridibus, coloribus variis resplendentibus, tenuissime seriatim 

 punctatis ; prothorace basi baud 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- 

 tennse rather slender, last joint elongate-ovate; prothorax 

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

 at the apex, minutely and sparsely punctm-ed ; 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 antennaj 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. Hoioittii 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 subtilitcr seriatim
