show a slightly recurved margin to the thorax, while Pascoe's 

 description of the elytra says " the punctures less regularly 

 arranged near the suture and base."' This is quite difierent from 

 Mr. Blackburn's interpretation of it, " with the seriate punctures 

 of the elytra interrupted only about the base and near the suture." 

 Specimens of /'. vicarius examined — it is the commonest species 

 in the Sydney district — have irregular punctures interspersed 

 with the seriate punctures to a slight degree. Pascoe also gives 

 Victoria as one of the localities for I', vicarius. I have received 

 specimens of it from various parts of Victoria, exactly corres- 

 ponding with Mr. Blackburn's description of P. ater. Of /'. 

 striato-jmnctatas Boisd., I speak with the usual doubt that is 

 associated with Boisduval's species. The description is useless, 

 but De Breme's figure and fuller detailed description are quite 

 consistent with the above synonymy; while many Museums in 

 Europe have Pascoe's species labelled /'. striato-punctatus Boisd. 

 (There is a specimen in the Howitt Coll. of the Melbourne 

 Museum, so labelled). Boisduval's locality was Kangaroo Island. 

 While this doubt remains, it is better to retain Pascoe's name. 

 I have transferred /'. vicarius from Section iii. to Section iv., in 

 the tabulation, which may be readily explained by its synonymy 

 with J', glaber Macl. There are very few species that have not 

 some indication of a linear arrangement in the elytral series of 

 punctures; in fact, P. nitiduloides Cart., is the only species in 

 which this arrangement is not traceable. The gradation between 

 Subsections iii. and iv., of Macleay, are not, therefore, clearly 

 defined; but in all the species tabulated in Section iv. above, the 

 irregular punctuation of the elytra is not confined to the basal, 

 sutural, and lateral regions. 



P. silphoides Breme, may or may not be Cilibe silphoides 

 Boisd. Macleay says that they are not identical, without giving 

 any evidence for his opinion. I have three specimens taken by 

 Mr. Hacker in the Cape Yoi'k district, that exactly corres- 

 pond with the figure and description given by De Breme, 

 but are quite unlike the species labelled P. silphoides Breme, 

 in the British Museum. While resembling many species of 

 S(/ra(/)is in the ovate convex form, my specimens are winged,
