of Petalocerous Insects. 153 



Genus. Cymophorus. 



Nasus apice rotundatus, reflexus. 



Jntennw decemarticulatae : scapo incrassato trigone ; ped'i- 

 cello articulo sequent! aequali ;* articulis intermedlis brevissimis 

 cyliiidricis ; capitulo longo admodum, triphyllo. 



Palpi articulo extimo oblongo obtuso. 



Lubrum sub rhinario pcuitus absconditum. 



Labium subquadratum, verlicale. 



J\Ic>i(um pone labium latitans horizontale. 



Oculi hemispha?rici : cantho carinato. 



Prothorax subquadratus, .antice angustatus : lateribus obtu- 

 sangulis. 



Scutelliim triangularej aequilaterale. 



Mesosiernum antice truncatum verticale, supra canaliculatum. 



Elytra lacunosa, longitudinaliter elevata, utrinque sinuata: 

 humerls fere lobatis, ut in quibusdura Gymnetidis & Cetoniadis.X 



Pedes. Tibice calcaribus 1, 2, 2. Cubitus edentulus. 



Un gutculi s\mp\\ces^ squales, breves, 2, 2, 2. 



Abdomen ano tricorni : cornubus lateralibus basi infus spiracu- 

 liferis. 



Corpus subdepressum squamulosum. 



This remarkable genus appears nearly related to the preceding, 

 and makes an approach, in some respects, to those Gymiietidce 

 whose elytra are lobed at the shoulders, yet the prothorax is not 

 porrected behind, so as to cover the scutellum ; it however most 

 resembles those Cetoniadce that are remarkable for their lobed 

 shoulders, and have an uncovered scutellum, such as C. Jlistrioj 

 versicolor, variegata, &c. but it wants the prominent character of 

 Cetoniadte, the scapular forming a fulcrum between the elytra 

 and prothorax : its place is probably between Cremastocheilus 

 and Gemichus +, which last exhibits the above character, and is 

 more nearly related to the Cctotiiada'. 

 Undutus. C. 



* Introd. to Ent. iii. 3G6. C. J I allude to a gpiuis of tliat family vvliicli 

 contains Cetonia marmorea, is Graculus, Lanius, i^c. F, which in my cabinet is 

 named Marniarina, and likewise to one containing Cetonia Ilistrio, Aiquinocti- 

 alis, F. &c. which I call Polybaphes. t Linn. Trans, xiv. 569.
