XXII. On the Australian species q/^ Tetracha. By Edwin 

 Beown. 



[Read 5th July, 1869.] 



Specimens of the Australian species of the genus Tetra- 

 cha have hitherto been very rare in European collections. 

 Baron Chaudoir in his ''Catalogue de la Collection de 

 Cicindeletes," published in 1865, only mentions one 

 species which he possessed from Australia. A recent 

 importation, however, of specimens, has afforded me the 

 opportunity of examining several species, which were 

 previously unknown in this country. Gemminger and 

 Harold, in Vol. i of their " Catalogus Coleopterorum," 

 issued . in 1868, notice the following species of Tetraclia 

 as from Australia. 



Australasice, Hope 

 australis, Chaud. 

 hasalis, McLeay 

 Bostockii, Castel. 

 crucigera, McLeay 

 Hopei, Castel. . 

 humeralis, McLeay 

 scapularis, McLeay 

 Waterhousei, Castel. 



Port Essington. 

 Nov. Holl. 

 Port Denison.

McLeay remarks that of these species, T. humeralis, 

 scapularis, crucigera, and Australasice, resemble each 

 other in being more or less margined with yellow. To 

 this group may also be added, as they are margined in 

 like manner, T. Hopei and BostocMi, and probably also 

 T. hasalis, but of the last-mentioned species I have not 

 yet seen the description. 



The species mentioned in the paragraph, as above, 

 will, therefore, stand as follows : — 



Section I. Elytra margined with yellow. 

 Tetraclia humeralis, . . McLeay.
