346 REVISION OF THE CICINDELID^E OF AUSTRALIA, 



Fabr., with which 0. semicincta Brulle, has been confused, must 

 be restricted to an African species from Senegal. C. semicincta 

 is remarkable for the long prominent white hairs on the upper 

 side of the fifth joint of the tarsi; these are present, but far less 

 developed, in other species of the group There are two forms 

 of C. semicincta in Australia, namely, one with the elytra greenish 

 (cT> 9) an( ^ with a white marginal stripe from shoulder to apex 

 (fig. 89); the other (I have only the £) with two decidedly 

 divided white marginal marks, one apical, the other lateral and 

 extending forward beyond the triangular dilatation that is always 

 found at about one-half the length of the elytra (fig. 88). Mr. 

 F. P. Dodd has sent me both these forms from Kuranda, Queens- 

 land; but I have not sufficient material to be able to give any 

 opinion on the value of the differences between the two forms. 



Range in Australia. — Sydney to Nickol Bay. It is also found 

 in New Caledonia, New Hebrides, New Guinea, and Java 



C. discreta Schaum, var. froggatti Macl. 



C. discreta Schaum, seems to range over the whole of the 

 Malay Archipelago, and to be differentiated into several sub- 

 species or varieties. Dr. W. Horn, to whom I sent specimens 

 (from the collection of the late Sir William Macleay) of C. frog- 

 gatti Macl., identified these as a form of C. discreta Schaum, for 

 which he had also proposed a separate name, var. sub/asciata* 

 I would index the Australian species as C. discreta Schaum, var.. 

 froggatti Macl. ( = var. sub/asciata Horn). 



C. master si-Subgroup . 



I do not know the extra- Australian affinities of the master si- 

 subgroup. It is not easy to tabulate the three closely allied 

 species which I recognise as composing this subgroup. 



G. plebeia SI., is differentiated from C. mastersi Cast., and 

 C. catoptriola Horn, by prothorax less rounded on sides; pro- 

 sternal episterna blue, almost smooth; elytra of a much blacker 



*This variety was described from specimens from Sumatra.
