Two specimens from Tasmania (Mount Wellington) may repre-

Head rather large. Eyes rather small, distant, finely 

 faceted. Ilostrum rather short, stout, feebly curved : scrobes 

 considerably widened posteriorly and partially visible from

 forming portion of club. Prothorax transverse, apex narrow and 

 subtubular. base bisinuate, ocular lobes almost rectangular. 

 Scutellum distinct. Elytra subcylindrical. baise trisiuuate. 

 Pectoral canal deep and wide, terminated before middle coxae.

 which Cryptorhynchus sirius. Er. belongs. Init with the mesos-
