494 NEW SPECIES OF AUSTRALIAN COLEOPTERA, 



Densely punctate, the head and prothorax moderately finely, 

 the elytra coarsely except in the vicinity of the (slightly raised) 

 suture. Metasternum rather coarsely punctate and transversely 

 wrinkled. Abdominal lamellae more coarsely punctured than and 

 terminated considerably before apex of basal segment. Length 5, 

 width 3 J mm. 



ZTa^.— Hobart, Tas. (Griffith & Lea). 



Much larger than the three blue species [cyaneus, cceruleus 

 and eminens) hitherto described and the under surface differently 

 coloured. To the naked eye the elytra appear to be devoid of 

 pubescence in patches, and these patches vary in position as the 

 insect is moved. 



Rhizobius calomeloides, n.sp. 



Rather elongate-elliptic. Dark j^ellowish-red (almost sangui- 

 neous), prothorax with a piceous blotch on each side of middle, 

 elytra (margins and suture excepted) piceous-brown or chocolate- 

 red. Clothed with rather long yellowish pubescence interspersed 

 with longer straggling hairs of a similar colour; pubescence of 

 under surface similarly coloured but unmixed and shorter. 



Head somewhat irregularly but rather feebly punctate. Pro- 

 thorax densely, moderately strongly and somewhat irregularly 

 punctate; scarcely twice as Avide as the length down middle; sides 

 strongly rounded. Elytra densely, coarsely and irregularly punc- 

 tate and with small punctures interspersed, near suture a few 

 large ones causing an apj^earance almost of striation, suture itself 

 feebly punctate. Intercoxal process of prosternum feebly 

 depressed, its sides distinctly carinate. Metasternum almost im- 

 punctate in middle, towards sides becoming rather densely punc- 

 tate. Abdomen densely punctate, the basal segment irregularly 

 so, largest punctures immediately behind lamellae, these small, 

 shining and rather strongly punctate. Length 5, width 3J (vix) 

 mm. 



ZTaS.— Tasmania (Mr. A. Simson, No. 3620), Hobart (Griffith 

 & Lea). 



The piceous blotches of the prothorax (to the naked e^^e) appear 

 to be conjoined and to occupy about one-third of the surface; the
