This is an extremely distinct species, and cannot well be 
confused with any other Australian member of the genus. 
The sculpture of the middle tibiæ (consisting of two well- 
defined teeth about the middle of the external margin and 
smaller teeth above and below) in itself distinguishes it from 
all its known Australian congeners. Also the fringe of elon- 
gate, hair-like setze on the lateral margins of the elytra are 
unusual, as well as the 16 longitudinal rows of sete on each 
elytron, many of which sete аге fasciculate on tubercles in 
the first, fourth, seventh, tenth, and thirteenth rows (in the 
sixteenth they are somewhat obscure and confused with the 
long marginal sete). Other unusual characters are the ex- 
ceptional feebleness of the inequalities on the pronotum and 
the width of the scutellum. The species is in some respects 
suggestive of the European T. hispidus, Laich., but very 
distinet, inter alia multa, by the strong convexity of its pro- 
notum, and the deep emargination of the base of that seg- 
ment on either side, which is almost as in T. Australasie, 
Er. The strong convexity of the humeral callus and the 
strong projection of the tubercles of the ninth sys- 
tematic series cause the true lateral margin of the 
elytra to be hidden in the front part, when the in- 
sect is looked down upon from above (from the 
point whence the two sides are seen symmetrically), so 
that the lateral margins from that point of view appear 
jagged, as in candidus, Har., and some other species.

1. sabulosus, Fab. I have found an example of this Euro- 
pean species among some Australian Coleoptera, given to 
me by Dr. Pulleine some years ago, and there is every reason 
to believe that it was taken somewhere near Adelaide.
