PLATYPHiEUS. 



Caput parvum ; rostrum subulatum, ai'cuatum, apice latius ; scrobes 

 postrnedianae, paruin obliquoe, ad oculum currentes. Scapm cla- 

 vatus, oculura haud attingens ; funiculi's 7-articulatus, articulo 

 basali longiusculo, eaeteris sensim brevioribus, ultimo solo trans- 

 verso, in clavam continuatis. Oculi modice angusti, fortiter 

 granulati, infra contigui. Prothorax latus, depressus, apice tubu- 

 latus, basi bisinnatns, lobis ocularibus haud prominulis. Elytra 

 depressa, prothorace haud latiora. Pyyidium tectum. Pectus am- 

 pliatum, integrum. Coxce antiee approximates. Pedes brevi- 

 usculi ; femora clavata, obsolete dentata ; tibice rectse ; tarsi bre- 

 viusculi. Abdomen segmentis duobus basalibus conjunctis, sutura 

 in medio arcuata. 



A genus allied to the Brazilian Parallelosomus, but differing 

 in its broader outline, very coarsely faceted eyes contiguous 

 beneath, more subulate rostrum, and scrobes commencing 

 behind the middle. In habit it is like Lyterins complanatus, 

 but longer. This is one of the most interesting discoveries 

 of Mr. Masters. 



Platyphceus lyterioides. 



P. rufo-castaneus, subnitidus, setulis albis valde adspersus ; rostro pro- 

 thorace longiorc, basi subseriatim punctato ; prothorace ampliato, 

 subtransverso, ante medium utrinque fortiter rotundato, apice 

 valde constricto, supra sat crebre leviter punctulato ; elytris 

 sulcato-punctatis, interstitiis subplanatis, rude punctatis ; corpore 

 infra punctis adsperso, singulis setam albam gerentibus. Long. 

 4 lin.
