310 NOTES ON AUSTRALIAN COLEOPTERA, 



crebre subtiliter, prothorace subtiliter minus crebre, punctu- 

 latis ; hoc quam longiori (et postice quam antice) duplo 

 latiori, lateribus (nisi in parte tertia antica) subparallelis, 

 angulis anticis sat rotundatis, posticis rectis ; elytris sat 

 fortiter striatis, striis (apicem versus profundioribus) punc- 

 turis minoribus crebris instructis, interstitiis subconvexis 

 fere ut pro thorax punctulatis ; abdomine crebre subtilius 

 fere rugulose sat sequaliter punctulato, longitudinaliter vix 

 manifeste rugate. [Long. 10|, lat. 5f lines. 



Probably resembles Amarygimts grandis, Macl., but appears to 

 be still larger. I presume it cannot be identical with that insect, 

 as the sculpture of the elyti-a of the latter is said to be " with 

 regular rows of small punctures * and the interstices minutely 

 and somewhat rugosely punctate." In both these respects the 

 present insect differs, having punctulate-striate elytra, and inter- 

 stitial puncturation not at all rugulose. Moreover, the " under 

 surface " of A. gi^andis is said to be " striolate," but in the 

 present species the striolation on the undersurface (so well- 

 defined in many of its congeners) is only feebly indicated. I 

 think too that Sir W. Macleay could hardly have described the 

 colouring of the elytra of this species as " cyaneous at the suture 

 and showing green, purple, blue, and coppery-red reflections over 

 the rest of their surface," without referring to the fact that the 

 colours are arranged in sharply defined vittae. They run as 

 follows : — suture narrowly golden, interstice 1 externally cyan- 

 eous, 2 green changing externally to golden, 3 golden changing 

 externally to purple, 4 purple, 5 and 6 green, 7 green changing 

 externally to purple, 8 purple changing externally to golden, 

 9 golden-green, external margin narrowly cyaneous. I possess an 

 example from Queensland which I believe to be Sir W. Macleay 's 

 A. grandis, and it is very different from the present species, but 

 as I am not sure of its identity with grandis it would be useless 

 to specify the differences.

♦Another species described at same time is said to have "punctate- 

 striate '' elytra, marking a distinction in this respect.
