An isolated species standing alone in this subgroup in having 

 well-defined black markings on the elytra. Structurally it is near 

 P. Icesa, Germ., but is much smaller and more nitid, with pro- 

 thoracic puncturation non-rugulose, interstitial puncturation of 

 elytra much less close, ifec. 



Australia; I do not know its exact habitat. 



P. BIMACULATA, OHv. 



This species has much superficial resemblance to the ordinary 

 form of P. agricola, Clip., and as both of them are variable in 

 colouring it is difficult to specify any sharply defined colour differ- 

 ence. In the present species, however, judging from the some- 

 what numerous examples before me, the dark marks on the pro- 

 thorax are only two (a vitta abbreviated at each end, on either 

 side of the middle), while in agi'icola the dark marks are almost 

 invariably more numerous often occupying almost the whole 

 surface of the segment. The under svirface and legs moreover in 

 the present species are rarely so dark in colour as in agricola. 

 P. bimaculata, however, is a manifestly less convex species than 

 P. agricola; with elytra less nitid, notably less distinctly striate, 

 and having the seriate punctures much more symmetrical [i.e., 

 running in single file, the regularity of the lines not (or scarcely 

 anywhere) disturbed by two or three of the punctures being placed 

 in a transverse row]. Long. 4-4 1 lines.

P. IRRISA, Newm. 



The Victorian Paropsi.n which I have little doubt is the subject 

 of this name is extremely like P. variicollis, Chp.; indeed, I know 

 not how to distinguish it from that species except by the sculpture 

 of the elytra, which are distinctly less strongly striate and especially 

 have their seriate punctures running in single file without (or
