110. Sclerorinus stewarti, Macl. ( ?) — South Australia: 



Blinman. Nearest to S. stewarti, but smaller than 

 type. The last three species are undoubtedly close 

 to one another, but differ in the relative size of the 

 tubercles and to some extent in the clothing. S. 

 tceniatus, Pasc, appears to be synonymous with S. 

 stewarti, Macl. 



111. Sclerorinus sublineatus, Germar. — South Australia: 



Moonta, Peterborough, Blanchetown, Adelaide, 

 Balaklava. A large series of specimens showing con- 

 siderable variation in size, comparative width, and 

 in the size of the elytral tubercles. S. marginatus, 

 Pasc, is synonymous. One specimen was labelled 

 "Northern Territory,'' probably an error. 



112. Sclerorinus pilularius, Macl. — South Australia: Mus- 



grave Range (R,. T. Maurice), Wilgena (L. C. Staple- 

 ton), Ouldea. Close to the last species but larger, 

 more ovate, and with somewhat different clothing. 



113. Sclerorinus, sp. ( ?) — A single 9 without locality, 



possibly a variety of S. sublineatus, Germar. 



114. Sclerorinus tuberculosus, Macl. — Victoria. 



115. Sclerorinus germari, Macl. — South Australia. Speci- 



mens agree with types ( ?) in Macleay collection. In 

 addition to these typical specimens were a number of 

 others which I prefer to regard as varieties rather 

 than as distinct species. 



1. d • No locality. Differs in having the median 

 ventral vitta of a dark-brown colour. 



2. 6 , $ • Wilmington. The S is a much longer 

 and narrower insect than the type of germari. 



3. d 5 $ • Kangaroo Island. Differs in having the 

 elytra somewhat longer in proportion to the pro- 

 thorax, and in the setae being of a yellowish colour. 



116. Sclerorinus parvulus, Macl. — South Australia. Speci- 



mens sent agree with the type ( ?) in the Macleay 

 collection. It is, however, doubtfully distinct from 

 S. germari, differing merely in the prothoracic- 

 granules being more rounded and less obsolescent. 



117. Sclerorinus mucronipennis, n. sp. 



118. Sclerorinus inconstans, Lea. — New South Wales: 



Mount Kosciusko. 



119. Sclerorinus alpicola, n. sp. 



120. Sclerorinus dilaticollis , Macl. — South Australia. 



121. Sclerorinus horridus, Macl. — South Australia : Fow- 



ler Bay, Port Lincoln, Ardrossan, Blanchetown,
