174 ON THE PSELAPIIID^E OF ATTSTRALIA, 



have now to describe. It was first found by Mr. Masters in an 

 entomological excursion among the Bkie ^Mountains ; and after- 

 wards it was captured by the same indefatigable collector in the 

 neighbourhood of Petersham. In both localities it was living 

 vmder bui'nt logs, half buried in the ground— a favorite habitat, 

 let me observe in passing, for other members of this family. Our 

 insect must be arranged under a new genus, for which a remark- 

 able peculiarity in the last joint of the antenna) has suggested a 

 name. 



Cyathiger. 



Paljn maxillares 3-articulati ai'ticulo 1™° elongato clavato, 2""*° 

 brevi cyathiformi, 3"" acinaciformi truncato. 



Aiitennce ad bases approximatas, capitatse, 7-articulatfe, articulo 

 1"*° longo, 2 — 6 suba^qualibus, 7"^° magno convexo-coucavo. 



Oculi parvi. 



Thorax brevis. 



Elijtra couvexa iutegra. 



Abdomen sutura unica. 



Tarsi 3-articulati. 



Gorjms setosum, alatum. 

 This genus appears to occupy a station midway between the 

 Fselapliides verce and the Clavigerides. It has the trophi of the 

 former and an abdomen more nearly allied to that of the latter 

 sub-division ; while the antennis have less joints than are found 

 in the former, and more than are found in the latter. It evidently 

 makes the transition from the true Pselapliidce to the abnormal 

 group less abrupt. The presence of eyes is no criterion, for 

 Articerus, which belongs to the Clavigerides has eyes, though 

 Claviger itself has none ; while though eyes are the rule in the 

 Fselajjhides verm, Amaurops is blind. 



CvATniGER PUKCTATUS. PI. xiv. 



Piceo-castaneus parce setosus, alte punctatus ; antennarum 

 articulo ultimo intus concavo extus convexo ; elytris linea 

 atque emargiuatione nulla; femoribus tuberculis armatis. 



Long. 0.05 poll. 



Loc. The Blue JMouutains and Petersham. Mr. Masters.
