Head rugulose-striolate, deeply channelled between eyes; front, 

 clypeus and sides beneath eyes glabrous. Antennae as in C. 

 ypsilori Dej. {i.e., four basal joints metallic, other joints blackish, 

 stout). Prothorax broader than long (1 - 8 x 2*3 mm.), lightly 

 rounded on sides; pronotum sparsely covered with white hairs 

 over the whole surface; anterior and posterior transverse impres- 

 sions not deep. Elytra oval (7 x 4 - 7 mm.); base with some white 

 hairs on each side of scutellum; apex roundly emarginate with a 

 short conspicuous spine at sutural apex of each elytron (at apex 

 of apical emargination). Under surface, except middle of 

 abdomen and metasternum, beset with white hairs. Legs albido- 

 pilose. Length 1.1 "5, breadth 4"7 mm. 



Hab. — S. W. Australia : Colls. French, Sloane (received by Mr. 

 C. French as from the Norseman District, Norseman being 120 

 miles north of Esperance; approximate position lat. 32° S., 

 long. 122° E ). 



It comes nearest C. scetigera Horn, among described Australian 

 species. Only the male of C. scetigera is known to me, from 

 which G. blackbumi presents the following nonsexual differences: 

 antennae with basal joint glabrous (only one long white seta), 

 clypeus, front and head beneath eyes without any white hair; 

 cupreous groundcolour of elytra overspreading far more of the 

 surface (extending to within 1 mm. of apex); the white margin is 

 narrow at the humeral angles and has a width of 0'5 mm. just 

 before and 07 mm. just after its median branch; this branch is 

 0*7 mm. in width and extends inward to within 8 mm. of the 

 suture. Mr. French obtained two specimens (g), one of which he 

 kindly gave to me. 



ClCINDELA S^TIGERA Horn. 



In his "Index" (1905) Dr. W. Horn places G.jungi Blackb., as 

 a synonym of C. scetigera Horn; and he has informed me by letter 

 that, after seeing Rainbow's figure of C. jungi, he has no doubt 

 of its identity with C scetigera Horn. I may add that one has 

 only to compare Horn's figure with Rainbow's to be convinced 

 that they represent the same species.
