.Mr. T. \'. Wullastuu on the Coleoptern vf St. 11,1, na. ;!!.»7 



Of the reimiinin;; flevt'n additions, finir I should nmsidcr of 

 rather more (h)ul»tt"ul orij^iu ; tor although 1 lielieve theui to 

 have beeonie established (like those just alluded to) tliroujj;h 

 indirect human agencies, this may or may not have been the 

 case. Tiiey are : — 



Thea varie<rnta. Oxyteliis alutaceifrons. 

 Xiiiithnliiius inorio. iiilidifrons. 



We now eome to the remaining scren in ^Ir. ]\Iellis.s's con- 

 vimnnent ; and these 1 feel no hesitation in asserting are veri- 

 table autochthoiws of the soil. Indeed, with the exception 

 of a Longitarsufi on an uiunistakably 8t. -Helena type, they 

 all belong to eitlier the Carculiouifhe or the Antliril)ids — in- 

 deed to the four genera Microxylobius^ Xesiof.es, Nuti'(we)iiis, 

 and Iloniceoderaj each peculiar to the island, and of very ano- 

 malous structure. These seven, of cons|)icuously native origin, 

 and which 1 may be permitted to call «//y«-indigenous, are : — 



Microxylobius diniidiatus. Notioxenus fprnigineus. 



aufjustiis. IloiiKrodcra coriucea. 



oossonoided. Lonyitarsus Mellissii*. 



Nesiott'S horridu-'. 



In my enumeration, two years ago, of tiie Colcoptera Avliich 

 had been detected up to that date (so far as 1 was able to 

 ascertain) at St. Helena, I recorded 74 species. Hence the 

 21 which the more recent reseaches of Mr. Melliss enable me 

 now to add will augment the entire number to 95. In draw- 

 ing any geograpliical conclusions^ however, from the general 

 character of a fauna, it is clear that those species which have 

 icithout dutibt become established through the immediate in- 

 stnnucntality of commerce and other direct human agencies 

 should be left out of the question; and consequently, when 

 tabulating, in 18G9, what I looked upon as emphatically the 

 " 8t.-Helena Coleoptera" (including under that title not 

 merely the actual autochthones of the soil, but likewise those 

 for the presence of which in the island the common modes of 

 ordinary dissemination, through various articles of merchan- 

 dize, Avould not directly account), I withdrew no less than 2(5 

 out of the entire 74, leaving a residuum of 48. Hence since, 

 on the same principle, 10, out of the 21 now added, have to 

 be removed, the " 48 " from which I deduced my conclusions 



• The uuniber of species, however, which I have re^'-arded in this 

 paper as new to .science i.s eleven, — tlie ('niptupliaffut^ r/racilipes, Xantlio- 

 tinus mono, Ox;/telu.s ahttareifr,iHt<, and O.ii/trlus uifidtfrons having, in ad- 

 dition to these seven '• aftra-indigenou.s " tbrni.-, been defined us novelties.
