SCLERORRHINUS, 
I believe Sir William has made far too many species of this 
genus from the South Australian specimens he had under ex- 
amination, not having allowed sufficiently for the variation of 
elytral tubercles, which often differ on the right and left sides 
of a specimen. 
SCLERORRHINUS ÅDELAIDÆ, Мас]. 
S. divaricatus and nodulosus at least, and possibly arenosus 
and a number of others, are synonymous. 
SCLERORRHINUS WATERHOUSEI, Macl. 
S. interioris is synonymous. 
SCLERORRHINUS ASPER, Macl. 
S. sordidus and acuminatus are synonymous. 
SCLERORRHINUS ANGUSTUS, Мас]. 
The unique specimen standine under this name in the Mac- 
A 8 D 
leay Museum is probably a male of emilis. 
NOTONOPHES,. 
Mr. Sloane refers but one species (Cubicorrhynchus cich- 
lodes) to this genus. The following species should also be 
referred to it:-—Talaurinus dumosus and spinosus, Macl., 
and lemnus and pupa, Pase. I do not believe, however, that 
all these names will eventually stand. 
ACANTHOLOPHUS CONVEXIUSCULUS, Macl., and HYBORRHYN- 
CHUS MASTERSI, Мас]. 
I have carefully examined the types of the above in the 
Macleay Museum (and also the specimens so named in the 
Sydney Museum), and find them identical. The Species be- 
longs to the same genus as Cubicorrhynchus spinicollis, 
Macl. does. 
AMYCTERUS DRACO, W. S. Macl. 
I have a male specimen (from Killerberrin, W.A.), which, 
on comparison with the type specimen of this Species, appeared 
to agree with it, except that the prothorax had five tubercles 
on one side and six on the other side of the middle. 
A. specimen (probably from the Murchison), which appears 
to be the female of the species (unknown to both the Mac- 
leays), differs in being much larger than the male (34 by 13 
mm.), the prothorax more decidedly flattened at the sides; the 
elytral tubercles much smaller and flattened, and the lateral 
row (except at apex), almost obsolete; the apex is strongly 
mucronate (the mucros fully a millimetre in length), thicken- 
ed, and obtusely granulate (not with a regular series of small
