following it. It is possible that the species I call ruficollis in the 

 following tabulation may be wrongly identified. 



Scutellaris is a good species. 



Apicalis (from Northern Queensland) is a good species. 



Sericeus, its author states, resembles aiistralis, Boisd.; but no 

 difference from that species is pointed out, and the description 

 applies perfectly to the species named australis in the Macleay 

 collection. I have not seen the type of sericeus, which is not in 

 the Macleay Museum, but is doubtless in the " Australian '' 

 Museum. 



Variicollis I think I know ; the type specimen is no doubt 

 with that of sericeus, and I have not seen it, but I have an ex- 

 ample from the neighbourhood where variicollis was taken, 

 which agrees well with the description. It seems to be a good 

 species. 



Vittatus is an extremely isolated species from tropical Queens- 

 land. 



The remaining three species (occidentalis, Meyricki, and dispar) 

 are of my own nomenclature. 



It will thus be seen that after all necessary weeding out 

 eighteen species remain which may be regarded as at present 

 forming the genus Phyllotocus. The following tabulation shows 

 satisfactory structural characters for distinguishing most of the 

 described species. There are however two (apicalis, Macl. and 

 marginijjeniiis, Macl.) which I am unable to place in the tabula- 

 tion owing to the vagueness of their descriptions. 



A. Elytra glabrous (ornearly so) except along their lateral margins. 

 B. Elytra nitid, not velvety, with interstices similar inter se and not 

 (or scarcely) convex. 

 C. Maxillary palpi elongate, their apical joint narrow and cylindric or 

 nearly so. 



D. Front tibiae in both sexes externally tridentate (including the 

 apical process). 

 E. Prothorax rectangular at base . . . Macleayi, Fisch. 



EE. Hind angles of prothorax strongly 



obtuse... ... ... ... bimaculatus, Er. 



DD. Front tibipe with only one tooth above 

 the apical projection. 

 E. Head testaceous ... ... ... occidentcdis, Blackb. 



EE. Head black ... ., ... Meyricki, Bl&ckh. 



CC. Maxillary palpi much shorter, their apical 



joint somewhat oval ... ... mcestus, Boisd. 



BB. Elytra more or less opaque, often velvety, 

 with convex unequal interstices. 

 C. Hind femora black or nearly so. 



D. Prothorax strongly lobed in the middle 



of base ... ... ... ... scutellaris, Macl. 



DD, Prothorax not (or scarcely) lobed in 

 middle of base. 

 E. Puncturation of prothorax faint and 



obscure (as usual in the genus) .. ustulatus, Blanch*
