318 Mr. T. V. Wollaston on the Cohoptera of St. Helena. 



from three examples now before me which were captured by 

 Mr. Melliss) to have established itself at St. Helena ; but as it 

 has equally become naturalized, through the medium of com- 

 merce, in most parts of the civilized world, it is of course 

 totally unconnected with the real fauna of the island. 



Fam. 13. PtinidaB. 



Genus 22. Gibbium. 



Scopoli, Intr. ad Hist. Nat. 505 (1777). 



25. Gibbium scotias*. 



Ptinus scotias, Fab., Spec. Ins. i. 74 (1831). 

 Gibbium scotias, Woll., Col. Atl. 214 (18G5). 



A single example of this European Ptinid is in the St. -He- 

 lena collection of Mr. Melliss ; but the species, of course, is a 

 mere importation, and might perhaps be found more plentifully 

 if searched for in the warehouses and town. It appears, in 

 like manner, to have become established at Madeira. 



Fam. 14. Anobiadae. 



Genus 23. Anobium. 



Fabricius, Syst. Ent. 62 (1775). 



26. Anobium velatum*. 



Anobium velatum, Woll., Ins. Mad. 276, t. v. f. 3 (1854). 



, Id., Cat. Mad. Col. 92 (1857). 



, Id., Cat. Can. Col. 249 (1864). 



, Id., Col. Atl. 226 (1865). 



A single example of an Anobium which Avas taken by Mr. 

 Melliss in St. Helena appears to me to be too close totheMadeiran 

 A. velatum to admit of its being separated from that species, 

 though perhaps its elytra are not quite so strongly punctate- 

 striate. Its extremely elongated suberect pubescence renders 

 it more in accordance with the A. velatum than with the Cana- 

 rian A. villosum of Brulle, though in point of fact the two 

 species are so intimately related that 1 cannot feel quite sure 

 that they are more in reality than modifications of a single 

 plastic form. If my conjecture, that in the more northern 

 archipelagos these particular species are considerably attached 

 to the old vine-trees, is correct, it is more than probable that 

 the one now before me may have been accidentally imported 

 into St. Helena.
