others is replaced by red-brown, and others are entirely of a dark 

 brown colour which has a reddish tone in the sutural region. 

 P. suturalis is a common insect in South and West Australia. 



P. PiCTiPENNis, Bohem. 



This species is very easily recognisable among its immediate 

 allies by its comparatively large size and the conspicuously 

 explanate lateral parts of its prothorax, which bear an elongate 

 feebly impressed fovea-like furrow (in some examples scarcely 

 traceable) at the inner margin of the explanate portion. It is so 

 well and fully described by its author that it will be sufficient 

 here to say that it is a strongly convex insect of subovate form 

 and of testaceous or reddish colour with (in a typical example) 

 the elytra somewhat darker except the lateral margin and two 

 inconspicuous fasciae, the one a little in front of, the other a little 

 behind, the middle. Varieties have the general colour of the 

 elytra lighter, so that the fascise are scarcely traceable ; and 

 others have the general colour of the elytra darker, but in these 

 the dark colouring is much reduced in area, so that the elytra 

 would be best described as testaceous, with the seriate punctures 

 blackish and three very irregular sinuous and interrupted fasciae 

 of blackish colour. The antennte ai'e black (except near the base), 

 elongate and filiform, but somewhat robust, with all the joints 

 considerably longer than wide and but little compressed. The 

 basal joint of the four anterior tarsi of the male is strongly 

 dilated. This species was sent to me from Dr. Chapuis' collec- 

 tion as P. minor, Marsh., but it does not agree with Marsham's 

 description or with Marsham's reputed type in the Macleay 

 collection, It is found in N.S. Wales and Victoria. Its size is 

 long. 3-3| lines. 



P. iENEiPENNis, Chp. (? (fnea, Blkb.). 



I have considerable hesitation in placing this species here; in 

 fact it is intermediate between Subgroups i. and iv., its almost 

 absolutely non-carinate elytral suture associating it with the 

 former, while its small size and non-foveolate prothorax refer it
