ibus, crebre fortiter punctulatis (quam P. carnose, paullo 
magis crebre), interstitiis sparsim fortius punctulatis modice 
elevatis, angulis humeralibus (a latere visis) vix rotundatis 
deorsum nullo modo productis; prosterni parte mediana 
modica, longitudinaliter suleata. Long., 44 1; lat., 4 1. 
A very distinct species owing to its strongly ovate form re- 
calling to mind the Tenebrionid genus Byrsax (figured in Journ. 
inte bev ple tia.,) fie. <7): 
The absence of a sinuation on the margin of the elytra behind 
the shoulder is also a notable character.

P. convexa, sp.nov. Fem. Ovata; minus nitida; valde convexa, 
elytris ante medium (ut P. consimilis, Baly) subgibbosis ; 
rufo-testacea ; capite prothoraceque ut precedentis sculp- 
turatis; antennis quam corporis dimidium  brevioribus, 
articulo 3° quam 1" vix longiori; prothorace quam longiori 
duplo latiori, cetera ut precedentis ; elytris quam latioribus 
vix longioribus, fere ut P. reticulate, Marsh., sculpturatis 
set etiam magis fortiter verrucosis, angulis humeralibus (a 
latere visis) vix rotundatis, deorsum vix productis ; pro- 
sterni parte mediana sat lata, longitudinaliter sulcata, sulci 
fundo longitudinaliter convexo. Long., 54 1.; lat., 41. 
With the form and elytral sculpture of P. reticulata, Marsh., 
this species has the prothorax closely and on the disc evenly 
punctulate with its sides strongly bisinuate, and the elytra 
subgibbous behind the scutellum as in P. consimilis, Baly. The 
last-named character distinguishes it from all the allied species, 
with which it is otherwise capable of confusion. 
S. Australia ; Fowler’s Bay. 
P. latissima, sp.nov. Mas. Subcircularis; sat nitida; sat con- 
vexa; sordide flavescens elytrorum disco infuscato ; capite 
crebre subtilius punctulato, longitudinaliter vix manifeste 
impresso ; antennis quam corporis dimidium sat longioribus, 
articulo 3° quam 1" vix longiori ; prothorace quam longiori 
paullo plus quam duplo latiori, antice sinuatim fortiter 
emarginato, postice bisinuato, in disco acervatim sat crebre 
sat fortiter (ad latera crasse) punctulato, interstitiis sparsim 
subtilius punctulatis, lateribus sat arcuatis sat fortiter 
bisinuatis, angulis anticis mucronatis posticis fere nullis ; 
elytris quam longioribus multo latioribus, grosse sat crebre 
punctulatis, interstitiis ineequaliter valde elevato-rugulosis, 
angulis humeralibus (a latere visis) rotundatis deorsum vix 
productis ; prosterni parte mediana modica, longitudinaliter 
sulcata. Long., 42 1.; lat., 41. 
Remarkable for the extreme coarseness of its elytral sculpture,
