. STENOTARSUS. 
The following two species may I think be attributed to this 
genus, which has not been previously recorded as Australian. As 
however they are both unique in my collection I have not been 
able to make a complete examination of their mouth organs. In 
respect of the other characters they agree well with Dr. Chapuis’ 
lengthy diagnosis, the only discrepancies I observe being that the 
surface of the prothorax is not marked with longitudinal furrows 
(there is a wide deeply concave space on either side immediately 
within the sub-lateral carina, but I do not think this is what Dr. 
Chapuis refers to) and that the basal ventral segment is (though 
fully as long as the following ¢hree segments together) scarcely as 
long as the following four together. 
S. arithmeticus, sp. nov. Ovalis; sat nitidus; pilis subtilibus 
erectis sat dense vestitus ; rufus, capite prothorace antennis. 
pedibus (tarsis exceptis) et in elytris notis binis (sc. macula 
discoidali figuram 2 simulanti mox ante mediam posita et 
macula ovali subapicali) nigris ; prothorace quam longiori 
plus quam duplo latiori, sparsissime punctulato, sat longe 
intra marginem carina longitudinali instructo et intra 
carinam profunde longitudinaliter concavo ; elytris sparsim 
sat fortiter punctulatis et marginem versus foveis sat magnis 
(his seriatim positis et prope apicem deficientibus) impressis; 
antennis sat crassis, quam corporis dimidium paullo brevior- 
vous:; Long. 14.13 lat.i1 4.1. 
The mark resembling on one elytron the figure 2 (on the other 
the same reversed) immediately in front of the middle of each 
elytron renders this species easy to recognise. 
Victoria. 
S. commodus, sp. nov. Breviter ovalis; sat nitidus; pilis sub- 
tilibus erectis sat dense vestitus; rufus, prothorace meta- 
sterno antennis (basi excepta) femoribus et in elytris notis 
nonnullis (sc. macula magna communi subrotundata mox 
pone scutellum posita et macula sublaterali magna difformi 
paullo ante medium posita) nigris; prothorace fere ut 
preecedentis sed quam longiori triplo latiori ; et antice inagis 
angustato ; elytrorum puncturis ut preecedentis sed Jaceribus 
magis rotundatis; antennis ut precedentis. Long., 141. 
(vix) >, lat. 14 1. 
Apart from the very different coloring and markings this in- 
sect differs from the preceding by its very evidently shorter and 
broader form as well as by its considerably more transverse pro- 
thorax which is more narrowed in front. 
Australia. I do not know-the exact habitat.
