Table of Species, 



A. Metepisterna not broader than long. 



B. Metepisterna and basal segments of abdomen punctate 



C. australis Dej. 

 C. convexus Cast, 



BB. Metepisterna impunctate ; ventral segments finely longitudinally 

 strigose, impunctate, except a transverse row of fine punctures on 



basal segment C. cAawrfoiVi Macl. 



AA. Metepisterna (with epimera) broader than long. 



C. Mesepisterna smooth (only a row of punctures at bottom of femoral 

 channel); metepisterna and ventral segments not punctate 



C. doddi SI. 

 C. nitidus Macl. 



CC. Mesepisterna, metepisterna, and ventral segments punctate. 

 D. Elytral interstices, after first, equal, depressed; striae light. 



Form oval C. gibhts Chaud . 



DD. Third and fifth elytral interstices evidently narrower than 

 fourth and sixth. Form elongate C. impar SI. 



Note. — Oodes fuscitarsis Blanchard, has been considered by 

 Chaudoir (Monograph, p. 509) as synonymous with C. australis 

 Dejean; but I am doubtful as to the correctness of this. Oodes 

 thoraciciis Qa.ste\n&\x, -which is placed by Chaudoir (Monograph, 

 p.5r2) as a Coptocarpus, is unknown to me. 



CoPTOCARPUS CONVKXUS Castelnau. 



Oodes convexus Castehiau, Trans. Roy. Soc. Victoria, viii., 

 1868, p,151; Coptocarpus convexus Chs^wdo'iv, Ann. Soc. Ent. Fr., 

 1882 (6), p.510. 



DiflFers from G . australis Dej., by shorter, more oval shape; 

 prothorax more strongly angustate to apex; head smaller; met- 

 episterna shorter. It is more polished and nitid; antennae, tibia?, 

 and tarsi of a clearer ferruginous colour. I ha\ e identified it 

 from the descriptions. Length 85 mm. (after Chaudoir). 



Hah. — W.A.: Mount Barker and Beverley (Lea), Roebuck 

 Bay(received from Mr. French). 



Var.1 C. championensis Chaudoir. — I have identified, from 

 comparison with Chaudoir's description, specimens collected by 

 Herren Michselsen and Harmeyer at Eradu, near Champion Bay.,
