giore ; prothorace basi angustiore, utrinque rotundato, sejunctim 

 puuctato ; scutello minuto ; elytris striato-punctatis, interstitiis 

 4°, 5°, 6° plus minusve albido-squamosis, postice setulis albis 

 raris munitis ; eorpore infra nigro, argenteo-squamoso ; apicibus 

 femorum, tibiis tarsisque fulvo-ferrugineis. Long. If lin. 

 Hah. Champion Bay. 



One of my specimens, which I take to be a female, has a 

 longer unicolorous rostrum. 



Olan^a. 

 Rostrum paulo arcuatum, apicem versus tenuius ; scrobes praemedianae, 

 obliquae, infra rostrum cito currentes. Scopus longiusculus, oculo 

 impingens ; funiculus 7-articulatus, articulo primo majusculo, 

 cseteris breviter obconicis ; clava distineta. OcuU minusculi, 

 tenuiter granulati. Protliorax angustior, postice rotundatus, basi 

 subtruncatus, lobis ocularibus nullis. Elytra oblonga, prothorace 

 multo latiora. Femora clavata, mutica ; tihm subflexuosae, apice 

 mueronatae ; tarsi ai'ticulo tertio bilobo, quarto elongate. Coxce 

 intermediae approximatae. Abdomen segmentis duobus basalibus 

 ampliatis, tribus intermediis ad latera arcuatis. Corpus setosum. 



This genus is trenchantly differentiated by the direction of 

 its scrobes and the absence of scales, except on the under parts. 

 Its affinities are doubtful. 



Olancea nigricollis. 

 0. ovalis, ferruginea, capita, rostro basi, prothorace, elytrisque mar- 

 ginibus suturaque nigris ; rostro prothorace paulo longiore, usque 

 ad medium parce albido-setosis ; antennis ferrugineis ; funiculi 

 articulo primo quam secundo, fere duplo longiore ; prothorace lon- 

 gitudine parum latiore, utrinque rotundato, crebre punctulato, 

 setulis erectis adsperso ; elytris oblongo-subcordiformibus, striato- 

 punctatis, interstitiis uniseriatim setosis ; eorpore infra nigro, 

 albo-squamoso. Long. 1^ Hn. 

 Ilab. Swan River (Albany). 



Antyllis. 

 Rostrum longiuscidum, cylindricum, vel apicem versus paulo attenu- 

 atum ; scrobes submedianaD, laterales, infra oculos desinentes. 

 Scap^cs oculum attingens ; funicidus B-articulatus, articulis duobus 

 basalibus breviusculis, caeteris transversis, Oculi minores. Ccttera 

 ut in Xeda. 



In general appearance like Xeda, but veiy trenchantly dif- 

 ferentiated by its six-jointed funicle. 



Antyllis setosa. 

 A. fusca, pedibus rufo-ferrugineis, unguiculis nigris, supra sat dense 

 griseo-, in medio cervino-squamosa ; rostro griseo-setoso, dimidio
