338 NOTES ON AUSTRALIAN COLEOPTERA, 



B. Elytra variegated with a distinct tesselated 

 pattern; prothorax in front moderately con- 

 stricted. 

 C. This pattern includes a conspicuous white 



mark crossing the suture about its middle... alhosignata. 

 CC. This pattern consists mainly of an irre- 

 gular common dark blotch on the basal 



half umhrosa. 



CCC. This pattern consists of small feiTuginous 



patches dispersed over an ashy ground. 



D. Rostrum distinctly arcuate in both sexes. 



E. Eostrum of male much shorter than of 



female assimilis. 



EE. Rostrum of male scarcely shorter than of 



female munda. 



DD. Rostrum almost straight in both sexes, notata. 

 BB. Elytra devoid of pattern ; prothorax in 



front strongly and suddenly constricted... gravis. 

 AA. Presternum not (or scarcely at all) concave 



in front of the anterior coxse B. scolopax, &c. 



CYDMiEA. 



I am morally certain of the correctness of my identification of 

 an example of Cydmcea htctuosa, Pasc, (a species with well- 

 defined and peculiar mai'kings), which was taken at no great 

 distance from Gawler — the locality of the type ; this example 

 agrees well with the generic description in all respects. I have 

 in my collection, however, several species that I am satisfied can- 

 not be separated generically which differ in some structural 

 characters, some having the mesosternum a little narrower 

 (though considerably wider than in many allied genera : e.g., 

 Olancea), and some having it wider still than in C. luctuosa, — 

 these latter, moreover, having the anterior coxse not quite con- 

 tiguous ; certainly none of them can find a place in any other 

 described genus. 



The species which I regard as Cydmtea have the following 

 characters in common : — Rostrum not very slender, arched,
