with the front angles of their prothorax rather more strongly 
directed outward which may possibly represent a distinct species. 
S. Australia. 
P. eyrensis, sp. nov. Precedenti (P. impressipenni) atftinis ; 
diftert elytris multo minus fortiter striatis, striis multo minus 
crebre punctulatis, interstitiis planis (latera apicemque 
versus vix convexis). Long., 1,5, 1.; lat., 21. 
Remarkably like the preceding but with very differently sculp- 
tured elytra. In- zmpressipennis these have deep strie witl 
crowded punctures giving them a catenulated appearance, while 
in the present species the strize are slight so that the sculpture is 
not very much more than rows of punctures on the surface, the 
several punctures in the rows being well isolated from their 
fellows. The very slight convexity of the interstices even near 
the apex and lateral margins further distinguishes this insect 
from the preceding. 
S. Australia ; near Lake Eyre. 
P. quadraticollis, sp. nov. Elongata; subparallela; minus 
convexa; sat nitida; eneo-picea, antennis pedibusque 
fulvescentibus, illis apicem versus piceo-tinctis ; capite lato, 
subtiliter strigoso et puncturis sat magnis leviter minus 
crebre impresso, sulcis interocularibus obsoletis, oculis inter 
se valde distantibus; antennis gracilibus quam corporis 
dimidium sat longioribus, articulo 1° quam 2" 3" que 
conjuncti (his inter se sat equalibus) vix  breviori ; 
prothorace quam longiori plus quam duplo latiori, crebre 
fortiter punctulato, quadrato, quam caput vix latiori, 
margine antico quam posticus latiori, lateribus fere rectis, 
angulis anticis incrassatis sed vix extrorsum directis ; elytris 
leviter striatis, striis crebre minus fortiter punctulatis 
(striz prime puncturis sat confusis), interstitiis vix (apicem 
versus nullo modo) convexis vix manifeste punctulatis. Long.,

Seems to be ailied to P. Waterhousei, Baly and Jaticeps, Baly 
(both from W. Australia) and to differ from them inter alia by 
the peculiar sculpture of its head, also by its prothorax being at 
at its widest across the front. 
S. Australia ; Quorn, &e. 
P. pallidior, sp.nov. Precedenti valde affinis; differt statura 
majore, colore toto (antennis apicem versus infuscatis 
exceptis) brunneo-testaceo, capite haud strigoso crebre sat 
equaliter punctulato, prothorace paullo minus fortiter minus 
crebre punctulato, elytrorum interstitiis subtiliter distincte 
punctulatis omnibus (extermis 2 vix convexis exceptis) 
planis. Long., 141; lat., 41.
