of Petalocerous Insects, 153 



Genus. Cymophoiius. 



Nasus apice rotundatus, reflexus. 



jintennce decemarticulatae : scapo incrassato trigono ; pedi- 

 cello articulo sequent! aequali ;* articulis intermediis brevissimis 

 cylindricis ; capitulo longo admodum, triphyllo. 



Palpi articulo extimo oblongo obtuso. 



Labrum sub rhinario penitus absconditum. 



Labium subquadratum, verticale. 



Mentum pone labium latitans horizontale. 



Oculi hemisphaerici : cantho carinato. 



Prothorax subquadratus, antice angustatus : lateribus obtu- 

 sangulis. 



Scutellum triangulare, aequilaterale. 



Mesosternum antice truncatum verticale, supra canaliculatum. 



Elytra lacunosa, longitudinaliter elevata, utrinque sinuata: 

 humeris fere lobatis, ut in quibusdum Gymnetidis & Cetoniadis»X 



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



Unguiculi simplices, aequales, breves, 2, 2, 2. 



Abdomen ano tricorni : cornubus lateralibus basi intus spiracu- 

 liferis. 



Corpus subdepressum squamulosum. 



This remarkable genus appears nearly related to the preceding, 

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

 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. Hisirioy 

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

 Cetoniadce, the scapular forming a fulcrum between the elytra 

 and prothorax : its place is probably between Cremastocheilus 

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

 more nearly related to the Cetoniada^, 

 Undatus. C. 



* Introd. to Ent. iii. 366. C. :}: I allude to a genus of that family which 

 contains Cetonia mannorea, 6^ Graculus, Lanius, S^c. F, which in my cabinet is 

 named Marmarina, and likewise to one containing Cetonia Ilisirio, ^quinocti- 

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