34 REMARKS ON THE LINNiEAN GENERA 



the Sinodendron with the Lucanides ; but in the third 

 volume of the Regne Animale, and more especially under 

 the article Lamellicorries in the Dictionnaire d'Histoire 

 Naturelle, he appears to think that the Cetoniidcc come the 

 nearest to the Lucanida of all the Petalocera. " Dans 

 quelques especes les mandibules des males sont beaucoiip 

 plus gra7ides que celles de femelles ; c'est ce qu^on ob- 

 serve dans les Lucaiies et dans phtsieurs Cetoines exoti- 

 ques; d' mitres males de ce dernier genre ainsi que ceux de

 rapports et de quelques autres fen ai coiwlu que les 

 Cetoines et les Trichies etoient de tons les Scarabees 

 de Linnaus, ceux qui se rapprochoient le plus de ses 

 Lucanes." But though the genus Cetonia does indeed 

 always with this author immediately precede Lucanus, I 

 cannot but think that, after having so acutely pointed out 

 the affinity which Sinodendron bears to both Oryctes and 

 Lucanus, he must have given the above reasons for uniting 

 this last to Cetonia, more from an experience of the diffi- 

 culty of placing them otherwise, according to our modern 

 systems, than on any very evident grounds of affinity. If 

 I may be allowed to differ in opinion ^vith an entomologist 

 of such celebrity, and to whom the science is so much in- 

 debted, I should say that the Cetoniidcc are of all the Pe- 

 talocera the most unlike to the Recttkera, and that their 

 membranaceous mandibles can never be assimilated to the 

 immense corneous mandibles of the Lucanida. '^ On the 

 other hand, I hope to prove that no insects in either co- 

 lumn of the Petalocera resemble the Recticera so much, 

 in general form and construction of the moutli, as the Ge- 

 otrupidce and Di/nastida. And with respect to the June-
