60 Mr. F. P. Pascoe on new Genera and Species of 



punctatis, interstitiis punctulatis ; subtus pedibusque pallide fer- 

 rugineis.

 mate ; antennae pale ferruginous, the last five joints gradually 

 thicker and very little longer than the three preceding ; pro- 

 thorax chestnut-brown, finely punctured, well rounded at the 

 sides, broad at the base ; scutellum triangular, brown ; elytra 

 brownish black, rather glossy, strongly striate-punctate, the

 2^ lines. 



Amarygmus ohtusus. 



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-

 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.

 tennae 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-
