702 HKTKROMERA, ifcc, FROM TROPICAL AUSTRALIA, 



The whole surface is less nitid and more strongly sculptured 

 than in F. victoriense. It is wider than, and easily distinguished 

 from, P. tetraspilotnm Hope. Type in Coll. Carter. 



I append a Table of the Australian species of this cosmopolitan 

 genus. 



Table of Platydema. 



1-7. Elytra unicolorous. 



2-4. Upper surface nitid-black. 



3. Form widelj^ oval and convex striatum Montr.; kanalense 



Perr, ; or itica Vase; ChamjjioniBla.ckh.; oJ)scurum Blackh. 



4. Form narrow and depressed deplanatum Champ. 



5. Upper surface opaque black (Typhohia) fulujineum Pasc. 



6. Upper surface piceous-brown laticoUe Macl. 



7. Upper surface metallic violet or Ijlue metaUicwm Cart. 



8-17. Elj^tra not unicolorous. 



9. Elj^tra black, with shoulder-spot and margins more or less 



luteous limacella Pasc. ; fossulatum Blackb. 



10. Elj^tra black with basal parts Bufous rufibast, n. sp. 



11. Upper surface piceous-brown, prothorax and elytra with 



pale margins ahdominale Geb. 



] 2. Elj' tra red, with large, discal, black macula rictoriense Blackb. 



13-17. Elytra more or less fasciated. 

 14-1(3. Form narrow and subparallel. 



lo. Prothorax black (sometimes with narrow red margins) 



tetraspilotnm Hope. 



Elj^tral intervals convex Pascoei Macl. ; tasmanicum Mass. 



16. Prothorax red, with black discal markings, elytra! intervals 



Hat hicinctum Champ. 



1 7. Fovea ovate, ely tral fascije pale yellow aries Pasc. 



]\'ote. — P. novicnm Motscli., has been omitted, as unknown to 

 me; moreover, if the dimensions stated in the description are 

 correct {Z^x\\.) it is most probably not a Platydema. The 

 width, as printed, is probably an error for 141. If this be so, it 

 is an evident synonym of Cei'opria peregi^ina Pasc. 



The species in which the $ has the head more or less horned 

 are P. aries Pasc, P. Hmacella Pasc, P. striatum. Montr., and 

 P.fuli(jineam Pasc, (in the last, it is only a slight tuberculous 

 elevation).
