74 Dr. H. Schaum on new Species of Cetoniidce. 



incurvEe. Tarsi lati antici palmati, posteriores compressi, 

 unguibus minutis $ . 



The structure of the tarsi of the male might justify tlie esta- 

 blishment of a peculiar subgenus for this extraordinary insect. 

 As it agrees however in its principal characters with Dtaphonia, 

 I have not thought it convenient to separate it. The hinder tibiae 

 of the male are curved, and the clava of the antennae as large as 

 the clypeus, like in the D. eucnemis, Burm., while the shape 

 of the sternum and of the pygidium is more like in D. dorsalis, 

 Donov. 



Sp. 18. Schizorrhina {Diaphonia) rugosa. (Tab. XI. fig. 6.) 



Crassa, supra nigra, fortiter punctata, clypeo toto, thoracisque 

 lateribus late testaceis, elytris brevibus, bicostatis, lateribus 

 densissime rugulosis, subtus testacea, pilosa, tarsis nigris. 



Long. 7 lin. 



Habitat in Nova Hollandia. Mus. Britan., Parrii et nostr. 



Corpore brevi crasso contracto, abdomine juxta elytra libero, 

 a reliquis hujus generis speciebus valde distincta. Caput 

 nigrum, nitidum, fortiter punctatum, clypeo brevi rotundato, 

 marginato antice subsinuato, hoc et macula annexa frontali 

 triangulari testaceis. Antennae nigrae, clava clypeo longi- 

 tudine. Thorax brevis, a basi ad apicem angustatus, lateri- 

 bus parum rotundatis, fortiter crebre punctatus, linea media 

 longitudinali laeviori, niger, subnitidus, lateribus late testaceis. 

 Scutellum basi punctis paucis impressis. Elytra thorace vix 

 dimidio longiora, postice angustata et rotundata, abdomen 

 non omnino obtegentia, supra disco costis duabus elevatis, 

 exteriore magis obsoleta juxta suturam fortiter crebre punc- 

 tata, extrorsum a costa interiore densissime rugulosa, fere 

 scabra ; costa tertia obsoleta juxta marginem exteriorem ob- 

 servatur. Pygidium valde inflexum, testaceum. Corpus 

 subtus testaceum, pilosum, abdominis segmentorum margi- 

 nibus nigris. Pedes breves testacei, villosi, femoribus anticis 

 supra, tibiis extus tarsisque totis nigris, his glabris. Tibiae 

 anticae fortiter bidentatse ^ . 



This species forms a peculiar division of the subgenus Dia- 

 phonia. The five specimens, which I have seen of it, were all 

 males.
