MlCROFERONlA AoELAIDiE, Blackb. 



The minute Carabid which I described under this name seems 

 to have been wrongly referred by me to the Feronini, as I find 

 that it has not the oblique sulcus traversing the elytral epipleurse 

 which appears to be an essential character of that sub-family. 

 Removed from the Feronini it must find its place, I think, among 

 the Anchomenini, and is probably related to Lestignathus and 

 Lacordairia, though it has not much superficial resemblance to 

 either of them. 



LOXANDRUS. 



The most salient character of this genus seems to consist in 

 the 3rd interstice of the elytra having only a single puncture, 

 and that placed slightly in front of the middle of the elytra ; 

 further characters may be found (at least for the Australian 

 species) in the total absence of the abbreviated basal stria of the 

 elytra, and the exceptionally conspicuous puncturation of the 

 ventral segments, which are not transversely sulcata. I am 

 unable to regard the presence or absence of wings as an essential 

 character (the Baron de Chandoir, I observe, associates winged 

 and apterous species in Leptojwdus), as I have before me an 

 apterous insect which presents all the above characters, and seems 

 to have no structural difference whatever from winged examples 

 of the genus, except the absence of wings. 



There is a generally distributed species of this genus of which 

 I have examples (apparently quite incapable inter se of specific 

 separation), from very widely divided localities, and which I 

 believe to have been described by the Count de Castelnau and 

 ISir W. Macleay as Pcecilus iridescens, Cast., and Pcecilus suhiri- 

 descens, Macl. It is a small insect (long. 4-4^ lines) of extremely 

 brilliant iridescence, with the parts of the mouth, the antennae 

 and the legs more or less reddish or reddish-brown, with the pro- 

 thorax (by measurement) very slightly transverse, punctulate 

 behind, somewhat quadrate, its greatest width about the middle, 

 its sides slightly arched, its hind angles roundly obtuse, and its
