thorax (almost twice as wide as long), by the sides of the 
pronotum extremely flat and dilated, by the reduction of 
all the carine of the pronotum except the middle two to 
mere small tubercles, by the third and fifth systematic series 
of the elytra being entire сагіпе, by the all but absolute 
disappearance of the median external tooth of the front 
tibiæ and by the strong free projection hindward of the pro- 
sternal process. 
T. asperatus, Macl.—Two specimens stand in the Macleay 
Museum as this species. They both appertain to the species 
that Harold named Crotchi. The latter is the older name. 
T. dilaticollis, Macl. 'Two specimens in the Macleay Mu- 
seum bear this name. They represent a species closely allied 
to T. Auguste, Blackb., but differing from it in having on 
its elytra well-defined rows of small setose tubercles (scarcely 
less defined than those of T. fenestratus, Har.). 
T. asperrimus, Macl. Two specimens in the Macleay Mu- 
seum are pinned into the ticket bearing this name. I can- 
not find any difference between them and the specimens 
(from the same locality) pinned into the next label (bearing 
the name wtreamaculatus } except that the two of the former 
name are more deeply covered with the indumentum usually 
obscuring the sculpture of these insects, and therefore seem 
to have less defined carinæ on the pronotum, etc. As the 
name asperrimus is evidenily founded on the presence of the 
indumentum and vitreomaculatus is a good descriptive name 
I propose retaining the latter, the two being of same date. 
T. salebrosus, Macl. Two specimens in the Australian 
Museum and one specimen in the Macleay Museum stand as 
this species. One of them has the carine of its pronotum 
blunter than the corresponding сатіпе in the two others, 
and there is some variation in the brilliance and conspicuous- 
ness of the nitid spaces on the elytra (which, however, might 
not be the case if the specimens were effectually cleaned). T 
am unable to find any good character distinguishing them 
from vitreomaculatus, Macl., and I consider them identical 
with that species. 
T. semicostatus, Macl. Two specimens attributed to this 
name are in each of the Sydney Museums. The species is a 
very distinct one, allied to Crotchi, Har., but very much 
smaller, and having'all the alternate elytral series continu- 
ously costiform in their basal half. 
T. nodicollis, Macl. Two specimens pinned into the tic- 
ket bearing this name in the Macleay Museum are somewhat 
closely allied to fenestratus, Har., but, inter alia, are much 
smaller and have the intervals between the systematic series 
of the elytra much more roughly sculptured.
