512 Mr. D. Sharp's descriptions of nciv genera 



wlio has contributed to our knowledge of tlie genus by the 

 description of two new species belonging to it. 



Articerus hrevipes, n. sp. ? . Rufo-ferrugineus, crebre 

 subtiliter punctatus, subopacus, brevissime setulosus ; 

 antennis brevibus, truncato-ovalibus, latitudine vix duplo 

 longioribus ; capite perbrevi ; prothorace brevi, transverso, 

 basin versus leviter angustato, pone medium impresso. 

 Long. corp. 1^ mm. 



Antenna3 about as long as the head, forming an oval, 

 with an extremely short stalk ; the base of the oval is lami- 

 nate, and its surface impressed, and the truncate apex 

 seen from the front is circular. The head is very short, 

 and the eyes are placed quite close to the hind part ; the 

 portion in front of the eyes is not so long as broad. The 

 thorax is in length considerably less than in width, and is 

 distinctly narrowed behind ; it is dull and opaque, its 

 punctuation indistinct, and it has an impression behind 

 the middle. The elytra are broad and short, a little nar- 

 rowed at the shoulders, their punctuation indistinct, and 

 the set£e even at the extremity very short and depressed. 

 The impression at the base of the hind body is transverse, 

 deep and well defined, the tuft of pubescence on each side 

 of it very small ; it is impunctate, and is furnished towards 

 the extremity with a few very short erect setre. The legs 

 are slender and very short. The sternum is shining in 

 the middle, closely but obsoletely punctured at the sides. 



Though I have seen but a single female individual of 

 this species I have described it, as I believe it wiU readily 

 be recognized from the above characters. 



This individual was ca^ptured in W. Australia by 

 INIr. Du Boulay, probably at Champion Bay. 



Articerus Kingius, n. sp. Rufo-ferrugineus, postice 

 latior ; capite thoraceque fortiter punctatis ; capite modice 

 elongate, antennis cylindricis apicem versus incrassatis, 

 apice truncato; elytris minus evidenter punctatis, nitidulis, 

 evidenter setulosis. Long. corp. 1^ — If mm. 



INIas, antennis capite evidenter longioribus, tibiis 

 anterioribus postice basi excepto laminato-dilatatis, in- 

 termediis latis, extus rotundatis, supra medium ciliatis, 

 intus apice unco acuto armatis ; abdomine apice deflexo ; 

 metasterno valde prominulo. 



Fem., antennis capite paulo longioribus.
