510 Mr. D. Sharp's descriptioiis of new genera 



sion. Thorax short, not so long as broad ; in front of the 

 base it has a deep curved impression, which is indistinctly 

 expanded in the middle and on each side, and in fl'ont of 

 this there is a longitudinal impression on the disc. Elytra 

 longer than the thorax, with a distinct sutural stria and a 

 fine abbreviated discoidal stria, these strias bemg deeply 

 impressed or foveolate at their commencement. Legs 

 rather short. 



Auckland. A single specimen (probably a female), 

 sent by Mr. Lawsou. 



Articerus Weshvoodi, n. sp. Rufo-ferrugineus, antice 

 fortiter punctatus ; antennis capite paulo longioribus, 

 latis, basi gracilibus ; prothorace subquadrato, dorso im- 

 presso. Long. corp. 1^ — 1^ mm. 



Mas, antennis extus paulo magis dilatatis ; tibiis ante- 

 rioribus basi gracilibus, apicem versus leviter dilatatis, 

 extus curvatis, intus infra medium vix visibiliter angulatis ; 

 tibiis intermediis extus medio spina parva, intus apice 

 unco valido ; posterioribus apicem versus leviter dilatatis ; 

 abdomine breviori, apice abrupte deflexo, pygidio apice 

 summo foveolato, segmento primo basali brevi, apice, 

 cumque segmentis sequentibus, medio impresso ; meta- 

 sterno medio apicem versus prominulo. 



The inner margin of the antennae is nearly straight in 

 the female, but a little concave in the male, and the apex 

 is broad and truncate, so that its two angles are right 

 angles in the female, while in the male the inner angle is 

 acute, the outer a little obtuse. The thorax is rather 

 longer than broad, very nearly straight at the sides, and 

 has along the middle a broad deep impression. 



West Australia: five specimens collected by Mr. Du 

 Boulay. 



I judge from description that this species is allied to A. 

 curvicornis, Westwood, but as it is smaller, and does not 

 quite agree with Westwood's description of the antennae, 

 and the $ characters, and as it comes from a different 

 locality, I have no doubt it will prove a distinct species. 



Articerus tumidus, n. sp. Rufo-ferrugineus, antice 

 fortiter punctatus, elytrisque evidenter setulosis; antennis 

 brevibus, capite paulo longioribus, intus extusque simila- 

 riter rotundatis ; prothorace quadrato, dorso foveolato. 

 Long. Corp. 1^^ mm.
