LAIUS. 
L. eremita, sp. nov. Subopacus ; haud setosus; coccineus, an- 
tennis nigris, elytrorum maculis binis (his marginem latera- 
lem nec suturam attingentibus, altera minori basali altera 
majori subapical1) piceis, pedibus infuscatis ; capite elytrisque 
(his sat brevibus) creberrime rugulosis vel potius coriaceis ; 
prothorace valde transverso, inzequali, subnitido, puncturis 
sat magnis leviter impressis ; oculis fortiter convexis. 
Maris antennarum articulo 2° valde compresso-dilatato, obovato, 
ad apicem subtruncato ; capite trans oculos quam prothorax 
fere latiori. Femina latet. . 
Hone, tb? 1.5 lat., = 1. 
A very distinct species owing to the uniform red color of its 
body with the exception of the two dark spots on the elytra ; its 
unicolorous black antenne are also characteristic. 
Central Australia ; near Oodnadatta. 
PTEROHELEUS. 
P. fraternus, sp. nov. Late ovalis; sat nitidus ; piceus antennis 
tarsisque dilutioribus; capite subtiliter obsolete minus 
crebre punctulato; prothorace fere levigato, quam longiori 
(et postice quam antice) fere triplo latiori, ad latera late 
explanato, marginibus lateralibus vix recurvis, angulis an- 
ticis obtusis sat productis posticis sat acutis, basi sat fortiter 
trisinuata; elytris subtiliter seriatim punctulatis, vix 
striatis, ad latera late explanatis, margine explanato ante 
medium intus dilatato apicem versus angustiori. Long., 7 1.; 
lat., 43 1. 
This species in its broad form with wide lateral margins of 
prothorax and elytra resembles P. picews, Kirby, near which it 
should be placed in the first group of the genus as subdivided by 
Sir W. Macleay (P.L.8., N.S.W., 1887, p. 520). Its compara- 
tively small size will distinguish it from all the other members of 
that group. Placed beside P. piceus it differs from the latter 
chiefly by its head and prothorax being even less distinctly punc- 
tured and its elytral sculpture consisting of mere rows of fine 
punctures becoming very faint near the apex, the interstices be- 
tween which are perfectly flat; while the elytra of piceus are 
distinctly punctulate-striate with distinctly convex interstices. 
Central Australia ; in my collection ; specimens taken by Mr. 
Zietz near Lake Callabonna scarcely differ. 
HELAEUS. 
H, interioris, Macl. Among the Coleoptera brought from 
Lake Callabonna by Mr. Zietz are a series of specimens which I 
attribute to this species, although Sir W. Macleay’s description
