surface) consists of isolated punctures of very equal size very 

 evenly distributed and not (or but little) larger than the punc- 

 tui-es of the series. The surface of the disc of the pi'othorax is 

 invariably non-rugulose and the puncturation of the same close 

 and fine (or, at any rate, by no means coarse), though in some 

 specimens more or less asperate. Most of the species with the 

 above mentioned characters are decidedly more nitid than those 

 that follow them. 



P. basalis I have identified from Dr. Chapuis' description, 

 where mention is made of the remarkable colouration of the elytra 

 (consisting in the elj^tral series becoming abruptly black at a 

 short distance from the base) to which I have seen no approach 

 in any other species of this subgroup. With the exception just 

 mentioned, the whole insect is of testaceous-brown colour. The 

 antennas are long and slender, the size notably larger (long. 5-5| 

 lines) than that of any of its immediate allies. Dr. Chapuis gives 

 Sydney as the locality where this species is found, but all that I 

 have seen wei-e taken in Western Australia. The punctures of 

 the elytra (both seriate and interstitial) are rather strong as com- 

 pared with those of most allied species, but those of the series 

 are quite as closely packed as in the following species. The 

 striation of the elytra also is better marked than in most of the 

 allied species, and in the female the interstices are distinctly 

 convex.
