396 Mr. T. V. Wollaston on the Coleopera of St. Helena. 



therefore propose to distinguish the Barbadoes specimen by 

 the name H.Eaivsom, and hope very shortly to be able to give 

 a more detailed description of this most interesting recent dis- 

 covery in crinoidal genera. 



Mr. Rawson observes : — " I have only procured one speci- 

 men of the Pentacrinus caput-medusoe^ and it was the first ; I 

 am therefore more uncertain about the place where it was 

 procured than I am about the habitat of the Pentacrinus Mill- 

 leri. But I believe that they are all procured on the same 

 bank, which, instead of five or six miles from the shore, as I 

 was first informed, cannot be more than a mile, within the 

 hundred-fathom line." 



XLIX. — On the Coleoptera of 8t. Helena. 

 By T. Vernon Wollaston, 'M.A., F.L.S. 



Since the publication of my memoir on the Coleoptera of 

 St. Helena, two years ago, another batch has been placed in 

 my hands by Mr. J. C Melliss, who has lately returned from 

 the island, and has brought with him a small additional col- 

 lection, of considerable interest. Although a very large pro- 

 portion of this last consignment is made up of species which 

 are manifestly naturalized (having been taken, clearly, in and 

 about the town), there is nevertheless a certain modicum of 

 unmistakably endemic forms ; and these, along with a few 

 others of more doubtful origin, I propose to describe in the 

 present paper. 



The total number of species in the collection which has 

 lately been entrusted to me by Mr. Melliss is 39 ; and of these 

 as many as 21 were not included in my enumeration in 1869. 

 Amongst the 21 additions, however, to the catalogue, there 

 are ten which we may be quite certain have found their way 

 into the island through the medium of commerce, and have 

 therefore no connexion whatever with the aboriginal fauna. 

 Such sjjccies as these figure in the local lists of nearly every 

 civilized country ; and as they are invariably admitted, on the 

 tacit understanding that they have unquestionably been natu- 

 ralized, we can scarcely refuse them a place in the St.-Helena 

 enumeration. The ten to which I allude are as follows : — 



Carpophilus cUmidiatus. Silvanus surinamensis. 



hemipterus. Curtomerus pilicornis. 



Trogosita mauritanica. Coptops bidens. 

 Cryptopliagus badius. Horaalota coriaria. 

 gvacilipes. Philonthus longicornis.
