P. DEPRESSA, Chp. 



Compared with P. II era this species is evidently wider and 



more depressed, with the apical flattening of the elytra somewhat 



lesi* pronounced. Its most notable distinction among its 



immediate allies consists in the fineness of the punctures in the 



elytral series, which are not much different in size from those of 



P. viorio, Fab., (as described earlier in this revision). The insect 



is of a red-brown colour, with the exception of a large suboval 



black blotch on the disc of each elytron immediately in front of 



the middle. Its length is 3 lines. I have seen only a single 



example (female) which is in the collection of Mr. Masters, so I 



cannot say whether the species is a variable one. It occurs in 



Queensland. 



P. TURBATA, Chp. 



This is probably the most depressed species in the genus. It 

 is of elongate-oval form, somewhat suggestive of the Carabid 

 genus Silphomorpha. The apical flattening of the elytra is 

 scarcely less pronounced than in /'. Hera. Its best characters 

 amongst its immediate allies seem to lie in the puncturation of 

 the lateral interstices of the elytra, which is as coarse as that of 

 the adjacent series. It is extremely variable in colour and 

 markings; the typical form is entirel}^ testaceous, except the back 

 of the head, the suture of the elytra (very narrowly), and a blotch 

 on the shoulders, whichfare infuscate. These infuscate markings 

 increase in a variable manner till in the extreme form known to 

 me the back of the head and a wide sutural and a wide sub- 

 naarginal vitta (the vittse uniting close to the apex) are black. 

 The middle part of the prosternum is very narrow and not dis- 

 tinctly sulcate (its lateral carinpe almost non-existent). The basal 

 joint of the 4 anterior tarsi in the male is only feebly dilated. 

 The length is 3i-3| lines. The species is found in W. Australia. 

 I have a specimen named by Dr. Chapuis.

With the two next following this species forms a small 

 aggregate distinguished from all closely allied to it by the strong
