444 REVISION OF THE AUSTRALIAN AMARYGMIDES, 



breviori, articulis 8-10 nuUo modo incrassatis quam prse- 

 cedentes haud brevioribus ; prothorace quam longiori (et 

 postice quam antice) fere tribus partibus latiori, subobsolete 

 sat crebre vix subtiliter punctulato (exempli typici utrinque 

 ante basin sulco oblique impresso), antice leviter sinuatim 

 emarginato, lateribus (superne viso) fere rectis a basi 

 antrorsum convergentibus, angulis anticis obtusis posticis 

 (superne visis) acutis ; elytris minus subtiliter seriatim 

 punctulatis, interstitiis planis obsoletissime vix perspicue 

 punctulatis ; prosterno medio concavo ; corpore subtus fere 

 Isevi, abdomine leviter rugato ; tarsis subtus nigro-setosis, 

 posticorum articuio basali quam ceteri conjunct! parum 

 breviori. [T^ong. 5^, lat. 2| lines. 



The prothoi'ax small and with its sides (viewed from above) 

 almost straight in their whole length, distinguishes this species 

 from all but a very small number of its congeners. The remark- 

 able obliquely placed furrow on either side of the prothorax a 

 little in front of the base is very likely to be merely accidental in 

 the typical specimen. The eyes (in the typical specimen) are too 

 much drawn back into the prothorax for the space dividing them 

 to be measured, but I can see that it is Just about half as wide as 

 in C. cujjrijyennis, Hope. The seriate punctures of the elytra are 

 not much diflferent from those in the middle part of the discal 

 series in cupripennis ; but their size does not vary noticeably in 

 the series towards the suture or lateral margins, and this, 

 together with the interstices being scarcely punctured, makes the 

 seriate punctures appear to a casual glance very much stronger 

 than in that species. The outline curve of the elytra (viewed 

 from the side) is very strong, its summit being almost behind the 

 middle of its length.
