Elytra Ijlack on disc, with wide testaceous margin 



G. lateralis, Casteln. f 



B. Prothoiax c<jrdate, liorder narrow, basal angles not promi- 

 nent C. peryphoides, Blkb. % 



C. Prothorax short, border not wide, basal angles rectangular. 



Elytra with the stri* formed of rows of punctures becoming 

 obsolete on apical declivity ; median line of prothorax 

 lightly impressed C. fortis, Blkl j. 



Elytra with strong punctate stria? extending to apex ; median 

 line of prothorax deeply impressed C. curtus, SI. 



II. Disc of prothoi'ax entirely covered with a strong punctura- 

 tion, size very small C. panctatus, 81. 



Cyclothorax curtus, n.sp. 



Oval, robust, convex ; elytra strongly punctate-striate. 



Black ; legs and antenna? reddish. Head short, convex, im- 

 pressed on each side between eyes ; impressions divergent behind. 

 Prothorax transverse (1 x 1-4 mm.); base and apex equal in 

 width ; sides evenly rounded ; base wide, lightly oblique on each 

 side to basal angles, these strongly marked, rectangular ; lateral 

 border narrow, reflexed, very shoi-tly sinuate just before the base, 

 meeting the base at right angles ; median line strongly impressed ; 

 a broad deep punctate fovea on each side of base ; the space between 

 these fovese convex, impunctate. Elytra wide (2-2 x 1-75 mm.), 

 convex, 9-striate ; strise deeply impressed on disc, extending to 

 apex, not i-eaching base (seventh lightly impressed), strongly 



t A species of Cydofhorax which I have taken in New South Wales at 

 Mulwala, on the Murray, and near Urana, agrees so well with the descrip- 

 tion of Phorticoxomw^ lateruli'i, Cissteln., that I have no hesitation in 

 regarding it as that species. C. rinrfipimuin, Blkb., seems to me certainly 

 the same species. 



:;: Specimens of a Cyclothorax are in my collection M'hich apparently 

 cannot bo differentiated from C. peryphoides, Blkb., unless by the testaceous 

 colour of the legs, a chara(;ter that is not likely of specific value ; a variety 

 with the apex of the elytra testaceous also occurs It is a widely distri- 

 buted species ; I have specimens from the following localities :— Victoria : 

 Ferntree (iully, Lillydale. N S.W. : Mulwala, Urana district, Windsor 

 (jl.ea), Clarence River (Lea).
