The Pachyrhynchi here described arc mostly due to the re- 

 searches of Dr. Semper in the Philippine Islands, and comprise 

 some of the most beautiful and isolated of the genus. Three 

 species only were found by Mr. Wallace in the Malayan archipe- 

 lago, two of which, derived from Dutch collectors, are described 

 by Van Yollenhoven ; the other, P. cingulatus, is new. The spe- 

 cies vary considerably in colour and the number of spots ; the 

 latter are almost entirely formed by scales more or less densely 

 seated in depressions of the derm ; sometimes, in some individuals, 

 a few scales may be found scattered on the head and prothorax 

 which are absent in others. 



Pachyrhynchus congestus. P. niger j nitidissimus ; prothorax ma- 

 culis quinque, elytra maculis numerosis majoribus (circa 20), quaruui 

 duabus communibus sutura pone medium sitis, e squamis cacruleatis 

 roseo-marginatis effectis; capite pedibusque omnino glabris, rostro 

 apicem versus subtiliter punctulato leviter transversim sulcato, in 

 medio late profunde excavato ; prothorace oblongo, antice fortiter ro- 

 tundato, postice angustiore, maculis minusculis cseruleatis ornato, 

 una basali, una antica laterali, altera supra insertionem coxarum 

 sita ; corpore infra maculis sex similibus et sic ut in praecedente locatis. 

 Long. 7 hn. 



The scales in this species are not close together ; their colour 

 therefore is not so marked to the naked eye. 



Pachyrhynchus cingulatus. P. niger, nitidissimus ; capite inter 

 oculos ad partem inferiorem fortiter sulcato ; rostro basi excepta sub- 

 rude insequaliter punctato, in medio leviter triangulariter impresso ; 

 funiculo articulis duobus basalibus modice elongatis, clava oblongo- 

 ovali; prothorace subtransverso, utrinque rotundato, margine ante- 

 teriore albo-squamoso ; elytris subovalibus, apicem versus paulo pro- 

 duces, apice ipso singulorum subacuto angulato, manifeste seriatim 

 punctato, in medio fascia mediocri, sutura postice macula rotundata 

 et margine posteriore albo-squamosis ; corpore infra cupro-nitente ; 

 pedibus pilis adspersis. Long. 5| lin. 



Hab. Morty. 



Allied to P. morotaiensis, Vollenh., but differs in the character 

 of the rostrum, the longer scape (which might almost place it in 

 Apocyrtus) and funicle, elytra more strongly punctured and pro- 

 duced at the apex, &c. 



Pachyrhynchus inclytus. P. splendide metallice viridis, vittis 

 maculisque e squamis stramineis effectis ornatus ; capite inter oculos, 

 genis rostrique apice utrinque squamosis ; antennis seneis, nitidis ;
