The opaque coarsely sculptured surface, veiy short apical "tails" 



of the elytra, and the basal joint of the funiculus nearly twice as 



long as the 2nd joint render this species very distinct from its 



described congenere. In some examples the spot of golden scales 



on the elytra is entirely wanting — perhaps owing to abrasion — 



bat I am not sure these do not repi-esent a distinct species, as 



their elytral "tails" are more slender and spine-like and quite 



devoid of hairs.

 This species is distinguished from all the pre\-iously described 

 Australian Rfvodinosomi by its head gradually narrowed from the 

 eyes hind ward. This character, however, approximates it to the 

 Xew Zealand R. acuminatv^^ Fab., from which, however (as 

 reiescribed by 3Ir. Waterhouse, Trans. Ent. Soc. ii), it differs 

 irU^er alia, by the scolpture of its head, which in R. cucuminatv^ is 

 said to have a large shallow fovea between the eyes and to be 

 coarsely punctured in front of the eyes and transversely furrowed 

 on the posterior part, whereas the head of the present insect is 

 not foveate between the eyes and is equally coarsely punctured on 

 its whole gtirface (l€«s closely behind than in front of the eyes), 

 with no transverse sculpture except under a strong lens some fine
