Head dark brown or reddish brown in colour, covered with a 

 thin greyish pubescence. Antennae about half as long again as the 

 body, with the fourth joint, which is the longest, distinctly longer 

 than the third or fifth, and the third joint scarcely longer than the 

 first, Prothorax armed a little behind the middle of each side with 

 a, short spine, the posterior face of which stands out almost at right 

 angles, while the anterior face is oblique and continuous with 

 the side of the prothorax in front of it. Elytra rather strongly 

 punctured, with the punctures for the most part irregularly placed, 

 but towards the sides of the disk, having a tendency to be arranged 

 in longitudinal rows ; reddish brown in colour, with a covering of 

 grey pubescence, which is interrupted by a number of dark -brown 

 patches. (In one of two specimens there is a large and conspicuous 

 dark-brown patch placed towards the side on the middle of each 

 elytron). Legs pale testaceous, with the thickened part of the 

 femora more or less infuscate. 



Two examples taken on the north coast of the island ; one in 

 March, the other in December. 



This species resembles ^gocidmis ignarus, Pasc, in colour, but 

 it is smaller in size, and differs from it also in the shape of the 

 lateral spine of its prothorax, and in the relative proportions of the 

 first, third, and fifth joints of the antenna).
