Lamellicorn Genus Popillia. 39 



and also a var. testaceipes of P. deplanata, Ohaus, both 

 described in the course of the same work. 



Having separated Popillia Q-guttata, Fairmaire, from the 

 genus Popillia, and formed for it the new genus Spilo- 

 popillia, figuring the species upon his plate, Kraatz, upon a 

 later page of his monograph, has described a very closely 

 related insect with all the same generic features as a Popillia 

 under the name of 6-maculata. This is a broader form, with 

 almost the same pattern, but nearly black ground-colour, 

 and the pronotum is smooth, with tine and scanty punctu- 

 ration. It should be called Spilopopillia Q-maculata. 



I have long ago recorded my opinion that Kraatz's genus 

 Poecilosticta must be for the present merged in Anomala. 

 The same applies to IJadropopillia, which is synonymous 

 with the subgenus Spilofa. 



The four species placed together as Ischnopopillia are not 

 naturally associated together. The description applies best 

 to ruyicollis, Newm., and moorei, Kr. (the female of the 

 latter was redescribed by Kraatz as andreicesi), of which the 

 former may be considered the type of the genus. 7". exarata 

 and erythroptera I consider species of Anomala. 



P.Jimbnata, Newm., does not belong to the genus. It 

 will be described in the 'Fauna of British India.' 



P. gemma, Newm., is not the species described by Kraatz 

 under that name. It is the same as P. metallicoliis, Fairrn. 

 Dr. Kraatz's species is named P. pndchra later in this paper. 



P. perotteti, Kr., is P. chlorion, Newm., of which P. cceru- 

 lea, Boh., is not a variety. The form from Szechuen called 

 perotteti, var. chrysitis, Kr., is a var. of P. inconstans, Fairm., 

 and not of perotteti. P. straminipennis, Kr., is ^-guttata, F., 

 and P. chinensis. var. sordida, Kr., is a form of the same 

 species and identical with P. castanoptera, Hope. The 

 so-called varieties of chinensis, purpurascens, and frivaldskyi 

 belong to yet another species distinguished by the smooth 

 pronotum and the quadrate clypeus of the male, which sex 

 was overlooked by Kraatz. 



P. andamanica, Kr., has been pronounced by Ohaus to be 

 only a variety of P. marginicollis, Hope, but it is a very 

 distinct species, marked, amongst other features, by the 

 absence of a mesosternal process. 



P. marginicollis, Hope, is the type of a group of species 

 all distinguished by a peculiar type of elytral striation, but 

 differing greatly in the form of the sternal process and other 

 features. As all those hitherto known have been confused 

 with P. marginicollis, I have tabulated and named here those 

 known to me. They differ from all other Oriental species in
