have previously described. M. Fauvel’s two species are very 
differently coloured, and no doubt differ in other respects, but the 
proportions of the segments, inter se, are not precisely stated. 
The shape of the anterior femora is peculiar, and would pro- 
bably justify generic separation ; it is not sexual. The outline 
of the under surface is emarginate on the apical half and is 
angular at the inner limit of the emargination ; the apex of the 
femur projects forward in a little spine or tooth. 
N.S. Wales ; Blue Mountains. 
S. latebricola, Blackb. 
S. dubius, Blackb. 
S. obscuripennis, Blackb. 
The front legs of the above three species are shaped as in 
S. femoralis. I regret that this character escaped my notice at 
the time I described them. 
AMPHICROUM. 
A. Adelaide, sp. nov. Rufo-testaceum, elytris dilutioribus (non- 
nullis exemplis plus minusve, presertim juxta scutellum 
maculatim infuscatis), nonnullis exemplis abdomine plus 
minusve infuscato; antennis modice elongatis, articulo 4° 
quam 3° breviori 5° zquali, 6-11 multo latioribus, 7-10 
modice transversis, 11° quam 10" longiori ; capite utrinque 
vix manifeste impresso, crebre equaliter sat fortiter punc- 
tulato; prothorace quam longiori fere duplo latiori, antice 
sat angustato, fere ut caput (sed minus crebre) punctulato, 
lateribus modice arcuatis, angulis posticis obtusis explanato- 
elevatis ; elytris quam prothorax circiter duplo longioribus, 
vix aliter punctulatis, apice truncatis angulis externis 
rotundatis ; abdomine crebre subtiliter punctulato; tibiis 
haud spinosis. 
Maris (?) abdomine sat lato retrorsum gradatim angustato, 
segmento ventrali penultimo quam antepenultimus fere 
duplo longiori, apicali conico ad apicem anguste truncato. 
Femina (?) abdomine magis parallelo, -segmento ventrali 
penultimo quam antepenultimus sat longiori, apicali pro- 
funde inciso, parte interna protrusa subspiniformi subtus 
longitudinaliter canaliculata. Long., 13—21.; lat., 31 
Differs from A. australe, Fvl., inter alia by its evenly punc- 
tured head, from A. spinipes by its non-spinose tibie, from 
A. cribriceps, Fvl., by its longer antenne, the ante-penultimate 
joints of which are less transverse. 
S. Australia ; near Adelaide, &c.; on flowers. 
A. cribriceps, Fvl. I have a short series (all males) of a species 
taken on flowers in the Blue Mountains, N.S.W., which agrees 
very well with M. Fauvel’s description of this insect except in
