fortiter longitudinaliter granuloso-punctulatis et tuber- 
culorum nitidorum seriebus circiter 10 instructis (serierum 3*, 
5", 7, 9* tuberculis quam ceterarum majoribus nec magnis, 
ceterarum quam granuli parum majoribus), latera versus 
plagulis nitidis planatis nonnullis ornatis; tibiis anticis 
externe quadridentatis, dente subapicali quam apicalis haud 
minore; processu prosternali fere truncato, in medio vix 
acuminato. Long., 6—6}1.; lat., 41. 
This species is remarkable for the very strong external teeth 
of its front tibize ; the tooth next above the apex is quite as large 
as the apical one (which is bitid) ; the next above that is smaller 
but, nevertheless, quite a strong tooth (larger than that in most 
species of Z’ros; which is next above the apical one); the upper- 
most is very small. The front tibize are thus very much as in 
the West Australian species, which I believe to be 7’. stellatus, 
Har., in which, however, inter alia the elytra are very differently 
sculptured.

T. Euclensis, sp. nov. Ovatus ; opacus; niger, indumento griseo 
vestitus ; capite fortiter minus crebre punctulato, tuberculis 
distinctis 2 instructo ; prothorace quam longiori tertia parte 
latiori, antice quam postice tertia parte angustiori, postice 
trisinuatim lobato, ut caput punctulato, supra costis tuber- 
culisque gracilibus inequali (costa 2" in medio interrupta, 
parte interrupta tuberculo nitido instructa), lateribus trisin- 
uatim rotundatis, angulis posticis sat rectis; elytris sub- 
serlatim sat crebre granulatis et tuberculorum parvorum 
seriebus circiter 7 ornatis (tuberculis his hic illic plus 
minusve in costis brevibus conjunctis), plagulis nitidis hic 
illic sparsim dispersis ; tibiis anticis externe trisinuatis vel 
obtuse tridentatis. Long., 5—7 1.; lat., 34441. 
This species is characterised by the following in combination ; 
frontal tubercles very well defined, ‘‘second” prothoracic costa 
widely interrupted behind the middle, the centre of the gap being 
occupied by a small shining tubercle, “fifth” prothoracic costa 
represented by a small shining tubercle, all the prothoracic cost 
very slender, sides of prothorax gently and somewhat trisinu- 
ately rounded, rows of tubercles on the elytra rather numerous, 
the alternate ones containing tubercles more or less larger than 
the intermediate ones (those of the second and fourth rows the 
largest); anterior tibie variable externally, in some examples 
somewhat obtusely tridentate, in others merely trisinuate. The 
prosternal process is sharply pointed behind.
