my collection under a microscope so as to make sure of correctly 
ascertaining the structure. The two species which I described 
(Tr. Roy. Soc. S.A. 1892, p. 98) as probably members of a new 
genus near Litochrus and which I called Z. (?) alpicola and 
L. (?) wniformis must also stand here and I think that which I 
called Olibrus victoriensis should be added. 
P. torridus, sp. nov. Late ovalis; nitidus; supra piceus plus 
minusve rufescens ; subtus, cum antennis palpis pedibusque, 
brunneo-testaceus ; capite prothoraceque fere levibus, elytris 
parte prope basin levi excepta seriatim distincte punctulatis, 
puncturis in seriebus subtilibus et crebre dispositis, stria 
suturali (hac pone elytrorum medium incipienti) bene im- 
pressa, interstitiis vix manifeste punctulatis; antennarum 
clava sat elongata ; hujus articulis 1° 2° que sat transversis 
intus quam extus multo magis dilatatis, articulo apicali 
quam precedentes 2 conjuncti vix breviori. Long., 1 1.;

This species bears considerable resemblance to P. (Litochrus) 
suturellus, Blackb., from which it differs inter alia by the large 
basal space devoid of sculpture on the elytra and by the sutural 
stria being altogether effaced on more than the anterior half of 
the elytra; also by the interstices of the elytral strie being 
almost impunctulate, only the one or two nearest to the suture 
bearing any defined punctures.

P. discoideus, sp. nov. Late ovalis ; nitidus; supra rufo-piceus, 
prothoracis lateribus et elytrorum macula magna communi 
indeterminata basin attingenti multo dilutioribus ; subtus 
cum antennis palpis pedibusque brunneo-testaceus ; capite 
prothorace que fere levibus, elytris (parte magna prope 
basin levi excepta) seriatim distincte punctulatis, puncturis 
in seriebus subtilibus sat sparsim dispositis, stria suturali 
(hac pone elytrorum medium incipienti) sat bene impressa, 
interstitiis vix manifeste punctulatis ; antennarum clava sat 
elongata; hujus articulis ut precedentis. Long. +1;

Smaller than the preceding and differently colored, also with 
the punctures in the elytral series a little finer and considerably 
less closely placed ; the elytra are of a dark red or piceous color, 
the whole disc being occupied by a common somewhat heart- 
shaped blotch of a testaceous red color; this blotch is not sharply 
defined, touches the base, extends to within a short distance of 
the apex and spreads out laterally so as to be separated from the 
margin on either side by a dark space equa! to about one-third of 
the width of an elytron. In certain lights the elytra of this
