Sab. North America, New Mexico \ Texas 2 .— Mexico, Nuevo Laredo in Tamaulipas, 

 Villa Lerdo in Durango (Edge), Monclova in Coahuila {Dr. Palmer). 



Allied to P. Jimbriatus, Burm., from S. Brazil and Uruguay. The elytra are shorter 

 and more rounded than in the typical Phileuri, and very coarsely striate-punctate. The 

 head bears no trace of horns, but is transversely carinated. In the male the pygidium 

 is conically convex, in the female plane. The size varies from 14 to 16 millim. 



2. Phileurus simplex. 



Oblongus, nigro-nitidus, sternis breviter vulpino-rufo pubescentibus pedibusque piceis : capite tenuiter arcuatim 

 strigoso, clypeo acute reflexo, fronte bituberculata extus nullo modo carinata, cantho oculari subito 

 rotundato-dilatato ; thoracis lateribus cum angulis posticis sat rotundatis, sulco dorsali punctate- nee 

 apicem nee basin attingente, antice nee tuberculato, disco anteriore sparse punctato, csetero leevi ; elytris 

 regulariter sat grosse punctato-striatis, apice confuse grosse punctatis. Tibia? anticse tridentatse, 4 posticse 

 carinis et apice breviter spinoso-setosis nee dentatis, apice extus tantum obtuse producto ; tarsi postici 

 articulo basali extus longe spinoso. § . Pygidium medio transversim valde gibbosum, sparse grosse 

 punctatum.

Two female examples. The species is closely allied to P. vervex, Burm., but differs 

 from it in the head above being nearly plane and without carinse connecting the frontal 

 tubercles with the sides and apex of the clypeus. The pubescence beneath is also 

 much shorter and thinner. 



II. Outer apical angle of the posterior tibiae sjpiniform. 

 A. Anterior tibiae trident ate. 



3. Phileurus laBvicauda. (Tab. XXI. fig. 3, e .) 



P. depresso proxime affinis, differt ventris segmento apicali fere laevi pygidioque grosse punctato. Oblongus, nigro- 

 nitidus, subtus pronoti lateribus solum rufo-hirtis ; capite grosse punctato, clypeo acuminato-reflexo, fronte 

 tuberculis compresso-conicis duobus, cantho oculari lobiformi capitisque lateribus ante canthum acute 

 angulatis ubi carina a basi tuberculi desinit ; thorace grosse punctato, disco utrinque et basi lsevibus, sulco 

 dorsali multo abbreviato punctato ; elytris regulariter punctato-sulcatis, striola scutellari nulla ; pectoris 

 lateribus coxisque posticis grosse umbilicato-punctatis. Pygidium grosse punctatum, c? mediocriter con- 

 vexum, $ planum ; segmento ultimo ventrali basi solum punctato. Tibiae 4 posticas medio et apice spina 

 elongata et valida.
