a new genus is required for its reception, but, until the male is 

 known, I am content to leave it in Talaurinus. 



Lea (Mem. Soc. Ent. Belg., 1910, p.77) described a single 

 species from Mt. Kosciusko, *S. inconstans, sl member of the 

 vest Uus- group. He also (Deutsch. Ent. Zeitschr., 1910, p.l61) 

 described a species, S. multigranulatus, which I have already 

 referred to Talaurinus * 



Within recent years, a number of species have been described 

 by myself. Of these, S. amycteroides (Proc. Roy. Soc. Victoria, 

 1914, p. 254) is a member of Group ii.; S. 7'egularis, S.neglectus, 

 and S. alhovittatus (Trans. Hoy. Soc. S. Australia, 1914) belong 

 to Group i ; S. Blackburni, JS. alpicola, and >S'. mucro7iipe7inis 

 {loc. cit.) to Group v.; while the descriptions of three other 

 species, S. inornatus, S. Dixoni, and >S'. Goudiei have been sent 

 to the Royal Society of Victoria for publication.! 



In Masters' Catalogue, 54 species of Sderorijius are listed; 

 three {S. carinaHis Boisd,, S. hopei Bohem., S. Spencei Hohem.,) 

 are included under Psalidura; one {S. molossns Pasc.) under 

 Talaurinus, and one (S. nigrospinosus Don.) under II ipporhi7ius. 

 To this number, 18 have been added of recent years. The 

 removal of synonyms, doubtfully valid species, and species re- 

 moved to other genera, reduces the number to 54. To these are 

 now added seven new species, making a total of 61. It is possible, 

 however, that some of the names on the unidentified list will be 

 found to belong to well-known species, in which case the number 

 of species will be further reduced. 



Classification. — In such a comparatively homogeneous genus, 

 there is little difficulty in arriving at a fairly satisfactory group- 

 ing of the species. In Talaurinus, this will always be the great 

 difficulty, and even if that genus- be subdivided, it will always 

 be hard to assign some species to their correct position. In 

 Scleroriiius, on the other hand, the chief stumbling block lies in 

 the great variability of many species, so that it is hard to say
