concave in front ; eyes moderately approximated ; antennas 

 slender, the two basal joints glossy ferruginous, the last four 

 pubescent, tawny ferruginous, opaque ; prothorax small, not 

 broad at the base, minutely punctured ; scutellum triangular ; 

 elytra striate-punctate, the strife shallow, the punctures rather 

 fine, the interstices of the striae very minutely and sparsely 

 punctured ; body beneath and legs glossy brownish black ; 

 tarsi tawny ferruginous. Length 4 lines. 



This species is allied to the following, but, inter alia, has a 

 broader and less elliptic outline, and is much less convex.

A. breviter elliptico-ovalis, sat fortiter convexus, fusco-niger, nitidus; 

 elytris viridi-nigris, leviter striato-punctatis. 



Hah. Queensland. 



Shortly elliptic oval, rather strongly convex, brownish 

 black, shining ; the elytra greenish black, without reflections ; 

 head scarcely concave in front, a little depressed along the 

 clypeal groove ; eyes not approximate ; antennas glossy ferru- 

 ginous, long, slender, the last joint narrowly oblong ; prothorax 

 small, rather narrow at the apex, very minutely punctured ; 

 scutellum triangular ; elytra striate-punctate, the strife shallow, 

 the punctures rather fine, the interstices obsoletely punctured ; 

 body beneath and femora glossy brownish black ; tarsi slender 

 and, with the tibiae, ferruginous. Length A\ lines. 



Amarygmus suturalis. 



A. breviter ovalis, sat fortiter convexus, aterrimus, nitidus ; elytris 

 purpureo-cupreis in fusca mutantibus, sutura viridi, fortiter

This and the two above are among the very few striated spe- 

 cies of the genus ; and of the striated species they are the most 

 convex and elliptical in outline. Besides the difference of
