in the species tabulation are obviously nothing but members of 

 Group iii. in which the verrucse are wanting The remainder, 

 however, have no connection with those six except by the acci- 

 dental circumstance of having on their elytra rows of punctures 

 which are not 10 in number; they are undoubtedly simply mem- 

 bers of Group V. in which the 10 series are either so much 

 interrupted or out of symmetry or so much obscured by interstitial 

 punctures as to be untraceable (indeed one or two of them — e.g., 

 M. )uscum, Boh. — might almost as well stand in Group v. as 

 Group iv., inasmuch as with careful attention the 10 series can 

 be made out scarcely less distinctly than in several — e.g.,jncnnda, 

 Chp. — which Dr. Chapuis placed in the other group). Nearly 

 all of them are small nitid species with brightly coloured sharply 

 defined markings. 



In Group iv. I place 27 species. Of these it is not clear 

 whether inidliseriata, Chp., belongs to the allies of Group iii or 

 of Group V. Of the remainder 7 belong to the former aggregate 

 and 19 to the latter. Of the 7 two are new species described 

 below ; one [P. ohscurella, Chp., from Central Australia) I am 

 confident I have not seen; and the other four I have been able to 

 identify confidently, though I have not seen an authentic type of 

 any. Of the 19 species forming the aggregate allied to Group v., 

 there are three that I am confident I have not seen — viz., 

 spectahilis, Chp.; paUidula, Chp.; and livida, Chp.; three ai^e 

 new species described below; three are represented in my collec- 

 tion by authentic types ; one is a species I have previously 

 described myself; and the i-emaining nine I have been able to 

 identify confidently by means of the descriptions. As in the 

 previous tabulations, the names of the species identified by com- 

 parison with descriptions are printed in italics. 



There may of course be some species belonging to this group 

 among those of Boisduval, I'c, which Dr. Chapuis considered to 

 be so insufiiciently described that they could not be referred to 

 any group, and which I have previously referred to. 



In most of the species of this group the markings are sufficiently 

 well-defined and constant to allow of their being used as reliable 

 characters in tabulation.
