Resembles C. eremda in sliape and in the structure of the 

 eyes, but differs widely from it in other i-es)3ects. The true 

 margin of the prothorax is exceptionally strongly rounded, but 

 although the true margin is not quite so bent dt)W)i (it is more so 

 than in C. eremitaj as to be quite invisible from above, its sti'ono- 

 curve is not apparent when the segment is viewed from above. 



W. Australia ; taken by E. Meyrick, Esq. 



N.B.— A somewhat larger example (long., 6| L),more attenuated 

 behind, and having tiie puncturation of the underside a little less 

 obsolete, and the colour a little more obscure, is probably the other 

 sex of this species. It was taken on the Elder Expedition by 

 Mr. Helms, in the Victoria Desert. I have founded this descrip- 

 tion on the example taken by Mr. Meyrick because I had already 

 applied to it and used the name C. Meyricki, altJiough no descrip- 

 tion has yet been published. 



-MORDELLID.t;. 

 MORDELLA. 



M. exilis, Germ. ? Several specimens of tlie insect which I take 

 to be this species were captured by Mr. Helms at the Eraser 

 Range. I believe M. exilis to be very variable and widely 

 distributed, but it is possible that some of the forms which 

 T refer to it may prove to be good species. The examples 

 from the Eraser Range are identical inter se, and are larger 

 and differently coloured from the type. It will perhaps be 

 advisable to give them a name even as a variety of exilis. 

 Tliis form might be characterised as follows : — 



Var. 'I ohscurior. Quam exemplum typicum major (Ion"., '1 



2-1- 1.), supra tota nigro-brunneo-pubescens. 

 I take this opportunity of characterising another insect which 



I hesitate to separate from M. exilis specifically, although to a 



casual ghmce it looks very distinct ; but I Iiave seen specimens 



that seem more or less intermediate. 



Var. 1 rufimanus. Quam exemplum typicum major (long., l-L . 



2 1.); supra Itete pallide brunneo-pubescens, certo adspectu 

 aurantiaco-micans ; subtus argentea, certo adspectu auran- 

 tiaco-micans ; capite antice femoribus anterioribus 4 et tibiis 

 anticis rufis. Hab., S. Australia (Port Lincoln).

ZONITIS. 



Z. Ih'Xinsi, sp. nov. Eusca, antennis tibiisquo obscurioribus ; 

 capite elongate, crebre rugulose sat ci'asse punctulato, anten- 

 narum articulo 3° quam 2'" triplo longiori; prothorace 

 sparsim minus fortiter punctulato ; elytiis pubescentibus, 

 crebre minus fortiter sat crasse punctulatis. Long, 3 J 1. ;
