Habitat Gomeram, in fungis putridis a DD. Crotch parce lectus. 



Four examples of this fine Xestus were taken by the Messrs. Crotch 

 in Gomera, from within a dead fungus on the sylvan mountains above 

 Hermigua ; and it is extremely interesting, as supplying us with a 

 second member of this curious genus. It is a little smaller, narrower, 

 and more shining than the Teneriifan X. throscoides, its anterior 

 portion being less evidently alutaceous ; its prothorax is relatively 

 longer, convexer, and more square, (instead of being conical) having 

 its sides equally (though very slightly) rounded before and behind, 

 with the anterior and (more especially) the posterior angles less pro- 

 duced ; its elytra are a little more convex, or laterally- compressed ; 

 its limbs are perhaps a trifle shorter ; and the last joint of its max- 

 illary palpi is somewhat less broadly securiform.
