the Teiiebrionidffi of Anstralia &c. 105 



A stronglj marked species, its habit suggesting the North- 

 American genus Nosoderma. 



m Amaryginus^ tyrrhenus. 



A. suboblongo-ovalis, violaceo-purpureus, vel violaceo-cbalybeatus, 

 nitidus ; elytris parallebs, striato-pimctatis, pimctis subapproxi- 

 matis, interstitiis modice couvexis, vix punctatis ; tarsis sat gra- 

 eilibus. 



Hah, Western Australia. 



Moderately oblong-oval, violet-purple, or steel-blue with a 

 violet tinge, glossy, and more or less varying according to the 

 light ; head not closely punctured, a little convex between the 

 eyes ; antennae black, rather short ; prothorax rather trans- 

 verse, minutely and somewhat remotely punctured ; scutellum 

 curvilinearly triangular; elytra somewliat narrow compara- 

 tively, the sides parallel, striato-punctate, the punctures rather 

 close, the intervals of the striaj moderately convex, nearly 

 impunctate, or with a very minute puncture here and there ; 

 body beneath glossy, black ; legs dark steel-blue. Length 

 4-5 lines. 



A striated species, with rather narrow elytra, especially in 

 the male — a character by which it appears to be well dif- 

 ferentiated. Mr. Masters sends me a specimen of ^. Howittii 

 {ante^ vol. iii. p. 348) from Port Lincoln, much more coppery 

 than the two I received from Dr. Howitt ; also two individuals 

 of ^. snfuralis {ante, vol. iii. p. 350), one of which is destitute of 

 the rich colour (bright golden green in the other) which adorns 

 the type specimen. 



Amarygmus ynauruJus. 



A. ovalis, niger, vix nitidus ; elytris cyaneo-uigris, leviter striato- 

 punctatis ; pedibus antennisque ferrugineis. 



Hob. New South Wales (Illawara). 



Oval, or in one sex narrowly oval, black, scarcely shining ; 

 head rather nan-ow, almost impunctate, the clypeus distinctly 

 punctured ; antennte slender, fen'uginous ; prothorax mode- 

 rately transverse, impunctate ; scutellum triangular ; elytra 

 dark blue-black, finely striate, the striaj with elongate, slightly 

 approximate punctures, the intervals of the strife rather broad, 

 not convex, with a very delicate scattered punctation ; body 

 beneath blackish brown ; legs ferruginous, the femora glossy, 

 tarsi slender. Length 3-3^ lines. 



A small dull-looking insect, approaching A. tarsalis, but 

 with a more approximate punctation on the elytra, and dif- 

 ferently coloured.
