214 On the Piinida: of the Canary Lslands. 



obsoletis) notato, angustulo, lateraliter compresso ; elytris 

 ovalibus, striato-punctatis ; antennis pedibusque elongatis,

Long. Corp. lin. 2i. 



Habitat sub lapidibus in ins. Palma, rarissima. 



The great size of this species, which is concolorous throughout 

 (being densely clothed with decumbent pale-brown scales) and is 

 quite free from erect hairs, in conjunction with its small, narrow, 

 laterally-compressed prothorax (which has two considerably ele- 

 vated ridges down its disk, but the external ones obsolete), will 

 readily distinguish it from the other members of the Ptinidce here 

 described. In general outline, both of prothorax and elytra, no 

 less than in the bicostate surface of the former, the total freedom 

 of the latter from additional pile, its large bulk, the slight ten" 

 dency which its elytra possess to have obscure subsetulose ridges 

 at their base, and the enormous development of the first-joint of 

 its hinder male-feet, it has much in common with the Casapus sub' 

 calvus from Hierro ; and indeed the fact that the latter insect is 

 somewhat aberrant in its group (having not only indications of 

 minute scales on its elytra, instead of hairs, but likewise the 

 extreme apex of its labial palpi almost entire) would perhaps 

 render this relationship the more striking ; nevertheless, every 

 point duly considered, I think there can be no doubt but that the 

 present species has (despite its unpilose body and swi-obtuse 

 mandibles) more in common with the type of Piotes than it has 

 with the aberration from the type of Casapus ; though, as implied 

 at the commencement of this memoir, it may be said to bring us 

 almost back again to the forms with which we started. 



The P. vestita appears to be extremely rare, the only two 

 specimens which I have seen having been captured by myself in 

 the island of Palma during June, J 858 — one high up in the Bar- 

 ranco above Santa Cruz, and the other in the laurel-woods above 

 Buenavista on the ascent to the Cumbre.
