the Tenelniniiida' of Australia ifr. 105 



A strongly marked species, its habit suggesting the North- 

 American genus Nosoderma. 



Amarygmus* tyrrhenus. 



A. subobloiigo-ovalis, violacco-purpureus, vel violacco-chalybeatiis, 

 iiilidus; clj^tris parallelis, stri.ito-iniiictatis, j)unctis sultapproxi- 

 nialis, intcrstitiis raodice coiivexLs, vix puudatis; tarsia sat gra- 

 cilibus. 



Hah. Western Australia. 



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

 vif)let tinge, glossy, and more or less varying according to the 

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

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

 verse, minutely and somewhat remotely punctured ; scutellum 

 curvilinearly triangular ; elytra somewhat narrow compara- 

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

 close, the intervals of the striae moderately convex, nearly 

 impunctate, or Avith 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 A. Hovnttu 

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

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

 oi A. suturah's {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 mauruJus. 



A. ovalis, niger, vix nitidus ; elj^ris cyaneo-nigris, leviter striato- 

 punctatis ; pedibus antenuisque ferrugineis. 



Hah. Xew South Wales (lUawara). 



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

 head rather nan'ow, almost impunctate, the clyjoeus distinctly 

 punctured ; antenna' slender, feiTuginous ; prothorax mode- 

 rately transverse, impmictate ; scutellum triangular ; elytra 

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

 approximate punctures, the intervals of the stride 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. tarsah's, but 

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

 ferently coloui-ed.
