iiot quite half as wide as the space between them. The elytra 

 are very slightly, but continuously, narrowed from the base in 

 their anterior two-thirds and then rounded off to their apex ; 

 their surface strongly scored all over with short transverse 

 impressions, punctured in 17 rows, the second, fourth, sixth, 

 eighth, tenth, and twelfth rows of punctures in rather deep 

 stricT, the rest not in stride ; tbe interstices flat ; the explanate 

 margin quite narrow, about a third the width of that of the 

 prothorax, and not narrowed behind. The elytra are finely 

 and sparingly granulate about the sides and apex. The suture 

 is distinctly elevated to the beginning of the declivous apical 

 portion, which slopes downward more strongly (but still quite 

 gently) at its commencement than behind, so that looked at 

 from the side the longitudinal outline appears sinuate behind. 

 Each elytron is separately pointed at the apex, leaving a wide 

 deep gap between the two apices. (It is just possible that this 

 is abnormal.) The eyes are only moderately separated. The 

 prosternum in my specimen is broken at the end, so I cannot 

 characterize it. The tarsi are ferruginous beneath. 



Eoseworthy. 



P. granulatus, Germ. Plentiful in many places near Ade- 

 laide. It has a kind of purplish bloom upon it that has nat 

 been noticed by its describers. The size varies from five to 

 seven lines. 



P. irisfis, Germ. In Mr. Macleay's Monograph (Proc. Linn. 

 Soc, jy-iS-W.) there is an error in the translation of Germar's 

 Latin description of this South Australian species which might 

 render the identification of the insect more difficult than it is, 

 to persons not possessing Germar's memoir. The learned 

 German says of the thorax, " densely and very finely punctate, 

 with somewliat larger jnmctures interspersed,''' not (as Mr. 

 Macleay has accidentally rendered the words I have italicised) 

 " the punctures rather large and scattered." It is obviously a 

 slip of the pen on Mr. Macleay's part, as wbat he has written 

 turns the sentence into nonsense. The original description is- 

 a very inferior one, so that it is impossible to be quite sure 

 what insect its author had before him ; but there is a species in 

 the South Australian Museum which I believe to be identical 

 with it.* I supply the following particulars concerning it, which 

 (important though they are) are not referred to by Germar. 



Perm narrow, elongate, parallel, and rather depressed (Long. 

 8i 1. Lat. 4f 1.) Thorax at base twice and a half its length 

 down the middle and twice the distance between the apices of 

 the front angles which just pass the front margins of the eyes. 

 Explanate margins of thorax together decidedly less tban half 



* Since this was written tbe Hon. W. Macleay has confirmed the identifi- 

 cation.
