1496 FURTHER NOTES ON AUSTRALIAN COLEOPTERA, 
The basal two joints of the antennas are entirely flavous, the 
following two are more or less infiiscate or piceous towards the 
apex, the rest black ; the fourth joint is a little longer than the 
third The hind body is infuscate to a variable extent, in some 
specimens the infuscation being confined to the middle part of the 
basal two or three segments while in others it suffuses the whole 
of the ventral segments except the last, leaN-ing, however, a flavous 
margin down either side.

Flava ; antennis mandibulis tibiLsque (basi excepta), et tarsls 
totis piceis vel nigris; elytris singulis (marginibus suturali laterali 
a]>icalique exceptis) cyaneo-nigris ; capite postice longitudinaliter 
canaliculate, inter oculos transversim impresso, obscure suberasse 
punctulato; prothorace quam longiori minus duplo latiori, inseqaali, 
crebre sat fortiter punctulato, antice et postice transversim, et 
alibi, impresso ; elytris crebre subtilius punctulatis.

The antennae are coloured as those of 0. Teppen ; the third and 
fourth joints are of equal length, the second very evidently shorter. 
The blue-black colouring on the elytra occupies the whole surface 
except a narrow border running entirely round each of them 
except at the base where it is wanting. 
Several species of Oides more or less resemVjling this insect have 
been described from Australia and elsewhere, from all of which 
the combination of characters mentioned above will, I think, 
distinguish it. Of Australian species it is no doubt nearest to 
0. dr(r*j,mflata.^ Paly, in which, however, the second joint of the 
antennae is as long as the third, and the prothorax is Jiriely punc- 
tulate ; 0. IcdahiU, Clark, has the hind body black and the lateral 
yellow margin not reaching the apex.
