Owing to the feebleness of its sculpture, the plece of this 
species in a tabulation is not very obvious without careful 
consideration. The nitid (and slightly elevated) spaces on 
the third, fifth, etc., systematic series are so much more con- 
spicuous than the ill-defined pubescent tubercles between 
them that at first sight the latter (which are the true tu- 
bercles of the series) might almost be overlooked, and the 
subsutural carina is so nearly obsolete that it is not very 
satisfactory to have to attribute to it any character at all. 
But in all genera of numerous species such cases of difficulty 
are to be expected where characters that serve well for identi- 
fying most of the species are less available in the case of 
occasional feebly developed species. The second, fourth, 
etc., systematic series of the elytra are sub-obsolete, but not 
(as they are in Brucki, Har.) absolutely wanting. The 
species, however, is easy to recognise, if in good condition, 
by the peculiar colouring, on which I have founded the 
name. The elytra present the appearance of being chequer- 
ed with patches of three colours: the nitid black squares in 
the alternate interstices, the dark brown derm, and the cin- 
ereous sete on the tubercles that are alternated with the 
nitid black squares. ts structural characters also render 
T. tricolor incapable of confusion with any of its described 
Australian congeners, as it is the only one ‘of those not hav- 
ing defined tubercles or granules in the second, fourth, etc., 
systematic series, having conspicuous nitid black spaces in 
the first, third, ete., series.
