Sp. 8. Sclerostomus Neotragus, Westw. (Plate XI. fig. 3.) 



Niger, opaciis ; capite transverso, utrinque pone oculos dente 

 parvo armato ; mandibulis porrectis, fere rectis, apice auri-

 prcsso, tuberculo elevato utrinque prope basin mandibula- 

 rum, angulis anticis oblique truncatis ; lateribusque pone 

 oculos spina parva utrinque porrecta armatis. Oculi cantho 

 dimidiatim incisi, antennarum clava 3-articulata. Mandi- 

 bulge porrectae fere rectas, capite paullo longiores ; supra 

 acute carinattC, apicibus dilatatis crassis auriculatis, dentibus 

 apicalibus intus extensis. Maxillee maris lobis duobus 

 longe ciliatis, interno simplici. Mentura transversum, angulis 

 anticis rotundatis ; laciniarum labii apicibus, articuloque 

 ultimo palporum labialium tantum expositis. Pronotum

Plate XI. fig. 3, Sclerostomus Neotragus, magnified; 3a, natural size; 3 6, 

 head and front of protliorax seen sideways ; 3 c, maxilla ; 3 d, mentuni seen 

 within, showing the labium and labial palpi. 



This remarkable species is unique, in the Collection of M. Dey- 

 roUe, of Paris, who has on all occasions allowed me an unlimited 

 use of any of his unique and interesting species. It agrees with 

 the Chilian species Dorcus cucullatus of Blanchard, in the cucul- 

 lated front of the pronotum, but differs in the form of the man- 

 dibles, unicolorous surface of the body, &c.
