observed that the distinctions just noted distinguish both sexes. 

 of the present species from the female of vittlpennis, but as I do 

 not know the male of that species it is possible that the inter- 

 stices may not be convex in that sex. Apart from the tarsi I do 

 not find any sexual characters in semivittata except the difference 

 of shape. 



N. S. Wales. 



P. ERUDITA, Newm. 



This is a species of dark colour with the head and prothorax 

 red (often more or less marked with blackish \ the legs in some 

 examples reddish, and each elytron with an oblique red blotch 

 which with its fellow on the other elytron forms a V. Its punc- 

 turation is not unlike that of the species described above as P. 

 morio. Fab., but the seriate are a trifle more evidently larger than 

 the interstitial punctures. The size is: long. 44-44 lines. It 

 occurs in N. S. Wales and Victoria. 



P. ELLIPTICA, Chp. 



This species is entirely testaceous or red-brown except that the 

 antennse are infuscate towards the apex and that in most 

 examples the under surface and legs are more or less piceous or 

 blackish; in some examples the hind part of the head is infuscate. 

 The puncturation of the elytra is a trifle stronger than in P. . 

 morio and the seriate punctures are manifestly (though not 

 much) larger than the interstitial, so that the series are quite 

 distinctly marked. The size is: long. 4-44 lines. The species is 

 found in W. Australia. I ha^e an example named by Dr. Chapuis. 



P. BRUNNBA, Marsh, (p. Clotho, Stal). 



I have an example before me which has been carefully com- 

 pared with the reputed type of Marsham in the Macleay Collec- 

 tion. The species is found in Victoria and N. S. Wales and 

 is fairly common. Its upper surface is extremely finely punctured 

 (in some examples scarcely distinctly except on the head) and 

 very nitid, the seriate punctures scarcely (or even not) distinct 

 from the interstitial. In this insect a character is strongly
