P. nig vita. Clip. — This species belongs to subgi'oup i. The 

 description does not indicate the characters necessary for that 

 determination, but I have recently obtained a specimen from 

 Chapuis' locality (S. Australia) which is evidently his insect. In 

 my tabulation (P.L.S N.S.W., 1898) the name should stand on 

 p. 226 under " B. General colour black or brassy or bluish-black,'' 

 but as my specimen is a female I cannot say whether it belongs 

 to the aggregate " C " or " CC." It, however, differs, inter alia, 

 from irirm by its very much finer elytral series of punctures, from 

 circumdata and subseriata by the very much closer puncturation 

 of its elytral interstices, and from all three by its much greater 

 convexity and entirely black colouring (except the under surface 

 of its tarsi and of the base of the antennae). 



P. cassidoi les, Boisd., puitctulata, Boisd., testacea, Oliv., and 

 vicina, Boisd. — The descriptions of these are such that it is 

 impossible to connect them with any insect unless the types could 

 be examined. 



/'. nshdaUt, Oliv. — This is in almost the same condition of 

 uncertainty as the preceding four. The description of the colours, 

 however, suggests the possibility of its being founded on a variety 

 of the insect that Germar described as P. suturaHs. This is little 

 more than a guess, but varieties of suturalis are the only Paropses 

 I have seen agreeing with the colours attributed to ustulata. 



P. cemida. Ch^)., tnitis, Chp., macidicoUis, Clk., and venusta, Er. 

 All these are names that I cannot associate with any insect, and 

 the descriptions do not furnish the necessary information for 

 placing them in my subgroups. All are small species (long. 2^ 

 lines or less) and they appear to me likely to be members of my 

 subgroup iv. 



In dealing with Group vi. I have enumerated 191 names which 

 have been applied to its species. Of these I have recognised and 

 tabulated 133 as representing valid species known to me, have 

 indicated 32 as more or less certainly synonyms, and have been 

 unable to furnish definite information concerning 26. The species 

 of my own naming are 42.
