of the Canary Islands. 15 



I have taken it at Orotava in Teneriffcj and in the district of 

 El Golfo on the west of Hierro. 



§ II. Palpi maxillares articulo ultimo securiformi, sed ad apicem

5. Xyletinus excavatus, n. sp. 



X. piceus, sat crebre punctulatus et pube longiuscula suberecta cinerea 

 dense tectus ; elytris obsoletissime subseriatim pubescentibus ; an- 

 tennis gracilibus, rufo-testaceis ; pedibus rufo-ferrugineis, tibiis 

 latiusculis, tarsis subgracilibus.

Well distinguished from the other Xyletini here described bv 

 its darker and more piceous hue, rather more erect and paler 

 pubescence, and somewhat broad tibise. Its tarsi also are a little 

 longer and slenderer than is the case in the allied species, and 

 have their basal joint (in proportion to the rest) more perceptibly 

 thickened. 



6. Xyletinus brevis, n. sp. 



X. rufo-brunneus, sat crebre punctulatus et pube longiuscula sub- 

 depressa flavo-cinerea tectus ; elytris breviter ovatis, ventricosis ; 

 antennis pedibusque rufo-testaceis. 



Long. Corp. lin. 1^. 



Habitat in ins. Palma, mense Maio 1858 repertus. 



The short-ovate outline of this interesting little Xyletinus, the 

 elytra of which are subventricose, and not at all parallel at their 

 sides, will at once distinguish it from the other species here 

 described. In the apically scooped-out terminal joint of its 

 maxillary palpi it agrees with the X. excavatus ; nevertheless the 

 emargination is somewhat less deep than in that insect, whilst 

 its totally different shape and paler hue will still further separate 

 it therefrom.
