LITOCHRUS. 
As explained above, I am obliged to refer to Litochrus provi- 
sionally, all the Australian species known to me presenting the 
characters of the group that M. Guillebeau has called “ Olibrinz.” 
Nevertheless three of them (the first three described below) 
might with some reason be separated generically from the rest on 
account of the great slenderness of their hind tarsi, the great 
elongation of the basal joint of the same, and the greater projec- 
tion beyond the intermediate cox of their metasternal lobe; the 
basal joint of their hind tarsi is longer than all the other joints 
together. None of the species previously described by me as 
Litochri exhibit these characters, but two of them (LZ. sutwrellus 
and lateralis) appear as noted below to fall into M. Guillebeau’s 
new genus Parasemus. 
L. coloratus, sp. nov. Ovalis; nitidus; rufus, prothoracis basa 
(anguste) elytrisque (apice sanguineo excepto) nigris ; supri 
fere levi (elytrorum stria suturali antice abbreviata excepta); 
metasterno medio sparsim setoso; tarsorum posticorum 
articulo basali quam ceteri conjuncti longiori. Long., 1,8; 1.; 
late 1

The conspicuous coloring of this pretty species renders it easily 
recognisable. It is all but devoid of sculpture even near the apex 
(the sutural stria excepted). There are however some faint 
transverse scratches on the elytra visible only from certain 
points of view. 
N. Queensland ; taken by Mr. Koebele near Cairns. 
L. pulchellus, sp.nov. Ovalis; nitidus; supra rufus, capite pos- 
tice prothoraceque (lateribus exceptis) obscuris, elytris 
(lateribus anguste apice late et macula communi magna 
transversa rufis exceptis) nigris ; capite prothoraceque sat 
levibus; elytris fere levibus (stria suturali antice abbreviata 
excepta) sed apicem versus obsoletissime punctulato-striatis ; 
corpore subtus lete brunneo; metasterno medio rufo, 
sparsim punctulato, vix manifeste setoso (? exempli typici 
abraso) ; tarsorum posticorum articulo basali quam ceteri 
conjnncti longiori. Long., ,°,—12 1 lat., +—3 1. 
The conspicuous elytral markings render this also a readily 
recognisable species. The elytra may be thus described :—Red, 
bearing a large common black ring which touches the base, nearly 
touches the lateral margins and is considerably separated from 
the apex. The enclosed central space (owing to irregularity in 
the shape of the black ring) presents the appearance of two 
roundish spots confluent for some distance along the suture. The 
elytra are not marked with transverse scratches.
