Habitat in Canaria, Teneriffa, Gomera, Palma et Hierro, passim. 



The Canarian specimens of this common European Latridius (which 

 has an excedingiy wide geographical range) have theii' elytra perhaps 

 a trifle more deeply punctate-striated (causing the interstices to ap- 

 pear rather more convex) than is the case in the ordinary ones and 

 in those from Madeira, and their humeral callus is more evidently 

 rufescent ; but I can detect nothing about them to warrant the suspi- 

 cion that they are specifically distinct. It is not a very abundant 

 insect in these islands, but widely distributed over them. I have 

 taken it in the region of El Monte in Grand Canary ; at the Agua 

 Garcia, the Agua Mansa, and Ycod el Alto, of Teneriffe ; in the Bar- 

 ranco da Agua of Palma ; and in Hierro. And it was captured, in 

 considerable numbers, by Dr. Crotch in Gomera. I have but little 

 doubt that it has been naturalized from more northern latitudes. 



255. Latridius opacipennis, n. sp. 



L. oblongo-ovatus, rufo-ferrugineus, opacus ; capite prothoraceque 

 profunde rugoso-punctatis, in medio canaHculatis, hoc latiusculo, 

 transverse, angulis anticis obtuse rotundato-ampliatis, postice 

 paulo angustiore, ad latera minute crenulato ; elytris subdepressis, 

 leviter substriato-punctatis, interstitiis latis planis ; antennis bre- 

 vibus, testaceis, clava minus abrupta. — Long. corp. lin. ^. 



Habitat Teneriffam sylvaticam, ad Agua Garcia semel tantum re- 

 pertus. 



Amongst many examples of the L. minutus taken at the Agua 

 Garcia, in Teneriffe, I find a single one which differs to a very re- 

 markable extent (in some measure indeed even structurally) from the 

 remainder ; and from this the above diagnosis has been compiled. It 

 differs from that species in its bright rufo-ferruginous hue, opalce and 

 less convex surface, in its verj' much broader prothorax (which has 

 the anterior angles largely and obtusely rounded, and its edges mi- 

 nutely crenulated), in its very Hghtly sculptured elytra (the striae of 

 which are scarcely at all impressed, and the interstices wide and 

 flattened), and in the less abrupt club of its rather shorter antennae.
