ON THE CETONIID^ OF SOUTH AFRICA.

spelling, which certainly ought to be Coryphe or Coryphaa. I prefer the former word, as it 

 appears to be what M. Gory was aiming at ; and, besides, means a lady's ornament, for which 

 purpose, in fact, some of the brilliant species of this sub-genus serve in the Phillippine islands.* 

 It is true that Dr. Leach gave this name " Corypha" to a groupe of Staphylinida ; but it has 

 never been adopted, so far as I know ; and Gory has certainly the right to name a groupe of 

 which he first pointed out very nearly the true hmits. It is distinguished from Schizorhina by 

 the porrected mesosternum diverging from the prothorax, by its often carinated vertex, and 

 clypeus always entire in front. From the sub-genus Goliathus, to which it is exceedingly 

 close, this sub-genus may be known by the maxillee having the terminal process shorter and in 

 a line with the base, and by the mentum being more truncated, but, above all, by the horny 

 part of the mandibles being much longer than the square membranaceous part. The males 

 scarcely ever have any teeth on the external side of their anterior tibise, and when they possess 

 such teeth it is merely because they belong to aberrant species.

I have named one of these sections after a prominent species. Mr. Kirby indicated another 

 under the name of Clilorocala, as did Mr. Hope another under the term Rhomborhina. The 

 second section in the above list is what MM. Gory and Perch eron term their genus 

 " Dicheros.'' And as for the first, M. Dupont has some right to name it, since one of the 

 insects he calls " Narycius" appears to belong to it. 



59. With respect, then, to the section Naryci^ of Dupont, I would observe, that it is 

 remarkable for its brilliant green colouring, whicli is sometimes rendered still more vivid by 

 spots of some different hug. The groupe is entirely Indian, and the Coryphe MacLeaii (the 

 Cetonia MacLeaii of Kirby) seems to be its best type. Here I may remark, that the Gnatho- 

 cera MacLeaii of Gory is not the Cetonia MacLeaii of Kirby. In the latter species the black 

 discal spot of the thorax does not touch its hinder margin, and besides the clypeus of the 

 male has not two parallel horns proceeding from its sides, but only one short vertical horn, 

 something like that of the well-known insect Coryphe flavomaculata, Fab. The Gnathocera 

 MacLeaii of Gory ought therefore to retain the trivial name it originally received from its disco- 

 verer Eschscholtz, and be henceforth called Coryphe pretiosa. But this species, together with 

 the insect called Narycius olivaceus by Dupont, and the beautiful Cetonia guttata of Ohvier,
