CANARIAN COLEOPTERA. 305 



ringly so, throughout the intermediate elevations of Tenoriffc and 

 Pahna — occurring amongst dense vegetation, in sylvan and subsj'lvan 

 spots. It is remarkable for its rather elongate, subcjiindrical pro- 

 thorax (which is constricted at the extreme base, and but slightly 

 widened hffore it), for its coarse punctation, which is also remote 

 on the elytra (which are more shining than the rest of the surface), 

 and for its longish rostrum and feet. Its colour would seem gene- 

 rally to be pale — merely the forehead and either side of the protho- 

 racic disc being more or less infuscated ; however, in one of my spe- 

 cimens, from the island of Palma, the suture, as well as the four 

 hinder femora, are likewise darkened. My Teneriffan examples are 

 from Las Mercedes, Souzal, and the Agua Garcia.

In the shape of its prothorax, as well as in its dense pimctation 

 and its not very shining elytra, this Auletes is exceedingly near to the 

 A. maderensis of the Madeiran Group ; from which it appears mainly 

 to differ (apart from its paler hue, on wliich I lay but little stress) in 

 its slightly longer rostrum, and in the rather less abbreviated and 

 somewhat less thickened second joint of its antennjB. From the A. 

 cylimlricollis, of Teneriffe and Palma, it may be known by its punc- 

 tation being altogether rather closer and less coarse, by its pro- 

 thorax being a little more expanded behind (or less cylindrical), by 

 its elj-tra being somewhat less shining, by its eyes being a trifle 

 smaller, by the second joint of its antennae being just perceptibly less 

 swollen, and the basal one of its feet being perhaps a little shorter. 

 Nevertheless, considering the excessive variability of the A. ct/Iindri- 

 colUs, I cannot but feel doubtful whether it is more than a mere in- 

 sular state of that species. As yet I have observed it only in Hieri'o, 

 where I captured two examples during February of 1858.
