624 STUDIES IN AUSTRALIAN ENTOMOLOGY, NO. XII., 



the conclusion that Pcecilus iridescens, Ccasteln., (of which the 

 type is lost) was a species of Loxandrus; but subsequent con- 

 sideration convinces me that this is a guess, and that the evidence 

 available, which is very slight, leads to the conclusion that P. 

 iridescens is closelj^ allied to, if not identical with, P. iridipennis. 



Genus CHLiENIOIDIUS. 



There is some synonymy amongst the species attributed to this 

 genus, all of which I have seen, and reduce to three, which ma}" 

 be tabulated as under : — 

 Black. 



Elytral interstices depressed for whole length C. prolixus, Erichs. 



Elytral interstices convex, particularly at apex... C. poeciloides, Chaud. 

 Upper surface green C. herbaceus, Chaud. 



Chl.enioidius prolixus, Erichson. 



Wiegm. Archiv, 1842, i., p. 127; Chaud., Bull Mosc, 1865, ii., 

 p. 110 : C. plcmipennis, MacL, Trans. Ent. Soc. N.S.W., ii., p.l09, 

 1871 : Paecilus sulcatulus, Macl., Proc. Linn. Soc. N.S.W., (2) iii., 



p. 47G, 1888. 



I have examined the types of Macleay's species, C. planijyennis 

 and P. sulcatulus (in the Australian and Macleay Museums 

 respectively), and have found them identical with C. prolixus. I 

 have also seen the type of Feronia (Pmcilas) funehris, Casteln., 

 in the Howitt Collection, and consider it, but without comparison, 

 a large specimen of C. prolixus. 



Hah. — Australia (universal; and Tasmania. 



Chl.enioidius pceciloides, Chaudoir. 



Bull. Mosc, 1878, Iii., p. 57 : Chkenioidius irideomicans, 

 Tschitsch., Hor. Soc. Ent. Ross., xxv., 1891. 



I have already suggested this synonymy {vide these Proceedings, 

 (2) ix., p. 410, 1894).
