Difiers from X. grandis^ Chaud, and suturata, Newm., by the 



much stronger and closer granulation of its eyes. From the 



other (except possibly several which are unknown to me but are 



certainly quite distinct) species having the sides of the pronotum 



widely dilated it is readily distinguished by (in combination) its 



fifth elytral interstice devoid of setigerous punctures, its third 



elytral interstice with only one setigerous puncture, and its 



elytral interstices not particularly closely punctured (much less 



closely than in X. vittata, Dej.).

X. cylindricollis, sp. nov. Elongata, angusta (quam latior fere 



quater longior), sat convexa ; nitida ; glabra; rufa, elytrorum 



apice antennis pedibusque dilutioribus ; capite pone oculos 



fortiter tumido ; oculis magnis, vix manifeste granulatis ; 



prothorace quam caput manifeste angustiori, quam latiori ut 



4 ad 3 longiori, subcylindrico, postice quam antice vix 



latiori, fere Isevi, longitudinaliter profunde canaliculato, 



canali integro), parte laterali minus late sulcata, lateribus 



ante medium leviter arcuatis pone medium leviter sinuatis, 



angulis posticis minus acutis leviter extrorsum directis ; 



elytris profunde striatis, striis crenulatis, interstitiis con- 



vexis subtiliter sparsissime punctalatis (3° puncturas seti- 



geras 3 ferenti). Long., 3 1.; lat., |- 1. (vix). 



It is with some hesitation that I refer this species to 

 Xanthophcea. It certainly does not look congeneric with 

 X. grandis, vittata, and their allies. But it is much more like (in 

 respect of facies) the species that Chaudoir placed in Xanthophcea 

 under the name ferriiginea, with which it might well be con- 

 generic. However, as Mr. Sloane has recently proposed an 

 arrangement of the Australian genera of Lehiides (Pr. L.S., 

 N.S.W., 1898) which seems to me satisfactory (at any rate pro- 

 visionally) and intelligible, that for me settles the matter, and I 

 think it well for workers on Australian Carabidm to follow as 

 much as possible his definitions of genera and so leave him a free 

 hand to improve his work himself if in some instances he should 

 find that his generic definitions 'are of too wide a character. Mr. 

 Sloane's essential characters for Xaidhophcea are " 4th joint of 

 tarsi bilobed, antennae inserted considerably in front of the eyes, 

 tarsi setose on the upper surface," all of which are characters of 

 the present species. He includes in Xanthophcea all the Aus- 

 tralian species that have hitherto been referred to Demetrias. 



The nearest ally known to me of this species is the insect dis- 

 cussed below under the name X. (Demetrias) longicollis, Macl., 

 from which it differs inter alia by its narrower and more convex 

 form, longer prothorax, and especially the well-marked dilatation 

 (behind the eyes) of the sides of its head. The last-mentioned
