Atenii that I have described except A. goyderensis (of the Horn 
expedition); the latter differs from it by its black color and much 
less coarsely punctulate prothorax. The species described by Sir 
W. Macleay as Ammuecii (some at least of which seem to be 
Atenii) all have either cariniform elytral interstices, or very 
deeply punctulate elytral striz or differ greatly in size from the 
present species, and are all from parts of Australia very far distant 
from Lake Callabonna.

TROX. 
T. Crotchi, Har. I have lately received an example from the 
collection of M. Thomson under this name, which agrees very 
well with Harold’s description and I have no doubt is correctly 
named. It is clearly identical with specimens from Central Aus- 
tralia which I had attributed to 7’. Crotchi and is very close to 
T. eremita, Blackb., but I think the latter is a good species, as it 
differs from the type of Crotchz in having the larger tubercles on 
its elytra less large and of more elongate form also more 
numerous than the corresponding tubercles in Crotchi and also 
differs in the external teeth of its front tibize considerably smaller 
and more obtuse. 
T. strzeleckensis, sp. nov. Sat late ovatus; opacus ; niger, 
indumento sordido vestitus; capite minus crebre nec rugulose 
punctulato, bituberculato ; clypeo antice fortiter angulato ; 
prothorace quam longiori fere duplo latiori, postice in medio 
fortiter lobato, ut caput punctulato, supra costis tuberculis- 
que nitidis sat angustis ineequali, lateribus sat fortiter trilo- 
batis, angulis posticis obtuse rectis; elytris seriebus 10 
tuberculorum elongatorum (his costas fractas simulantibus) 
inter se equalibus insignibus, tuberculis majoribus vix 
elevatis nitidissimis per superficiem totam hic illic inter- 
mixtis, serierum interspatiis seriatim minute granulatis ; 
tibiis anticis extus dentibus 2 (mediano et apicali) permag- 
nis armatis ; prosterno postice vix prominulo. Long., 6—7 
l.; lat., 4—42 1. 
The sculpture of the elytra is the strongly distinctive character 
of this species ; it consists of eight opaque rusty-looking carini- 
form lines on each elytron which are similar inter se except that 
the second and fourth are less broken near the base than the rest, 
each of which is broken into short pieces (about 15 in number), 
and besides which there are on each elytron a somewhat similar 
but less defined line close to the suture and two ill-defined ones 
between the eighth and the lateral margin, a number of scarcely 
elevated somewhat star-shaped nitid spaces scattered confusedly 
over the elytra, and a row of very minute granules between each
