238 XVLIXADES MARMORATUS. 



hairs on the prothorax and especially towards the extremity 

 of the elytra. 



Rostrum somewhat longer and more narrowed between 

 the insertion of the antennae than in the allied species, 

 slightly and transversely depressed at the base, and pro- 

 vided with three deep longitudinal impressions, continued 

 on tlie forehead; the median impression widens out supe- 

 riorly and interiorly, and there surrounds a very short and 

 naked keel ; the naked keel of the inferior widening is 

 attached to the upturned front margin Avhich surrounds the 

 terminal notch. The lateral impressions of the rostrum 

 approach each other towards the middle and are here 

 sometimes interrupted. 



Antennae still more robust than in X. Westermanni and 

 having the basal joints shorter; the two apical joints of 

 the club are velvety. 



The head naked on the vertex and behind the eyes, 

 very finely chagrined. 



Prothorax more long than broad , gradually widening out 

 on the sides of the base up to the anterior third where 

 it is widest. Its base with a narrow upturned edge and 

 a little more forward with a short keel which is some- 

 times interrupted in the middle and does not reach to the 

 posterior angles. The sides of the prothorax provided 

 with two keels somewhat bent inward at the base , the 

 inferior of which is somewhat directed upward at the an- 

 terior angle. The disk has two small impressed lines on 

 the sides of its anterior portion and a small number of 

 shining granulations towards the middle Dark spots form 

 a regular figure on the middle of the prothorax , one spot 

 being in the centre and surrounded by four others , two 

 of which are attached to the front margin , two others to 

 the base. The space between the lateral keels and the 

 anterior angle are also of a dark color. The sides of the 

 prothorax are covered with large punctures. Scutellum 

 hardly visible. 



Elytra of the same shape as those of JC. Westermanni ,
