208 Mr. T. V. Wollaston on certain Coleoptera 



give a critical enumeration of them, and so add a mite to our small, 

 but growing, knowledge of that curious eccentricity which is so fre- 

 quently conspicuous amongst remote insular forms. 



On glancing over the following catalogue, it will be perceived that, 

 of Mr. Bcwicke's fourteen species, two belong to the Geodephaga, 

 eight to the lihyncJwphora, and one to the Lamellicornia, Phytophaga, 

 //■ U romera, andPseudotrimera, respectively, — indicating a marvellous 

 majority for the weevils, which, if we remove from the list the 

 PristonycJius complanatus (which is clearly an introduced insect, and 

 one which has established itself in almost all the Atlantic islands), 

 will number nearly two-thirds of the entire lot ! And if we con- 

 sider, further, that the six extra-Rhynchophorous forms belong to 

 well-known genera {Calosoma, Pristonychus, Heteronychus, Longi- 

 tarsus, Opatrum, and Cydonia), -and that at least three of them are 

 identical with widely-distributed species, whilst the eight Ilhynelio- 

 phora are all of them endemic both in species and genus — and not 

 merely " endemic," but anomalous in structure in proportion to the 

 remoteness of their habitat, — we shall scarcely fail to be struck by the 

 conviction that the Curcidionidai will, in all probability, be found to 

 play a most important part in the Coleopterous fauna of St. Helena. 

 Indeed, in the remarks under Microxylobius, I have expressed my 

 belief (from the mere diversity of configuration presented by the five 

 exponents there described) that it is almost certain that the members 

 of that abnormal little group are (in species) locally abundant, and 

 that consequently many additional representatives may yet be looked 

 for : and since the same might be urged, with no less force, for that 

 extraordinary genus Notioxenus, there is every reason for suspecting 

 that the lihyncliophora of this mountain-island are (in proportion to 

 its size) both numerous and eccentric.

1. Calosoma haligcna, n. sp. 



('. supra obscure seneum, subtus nigrum ; capite irregulariter punctato ; 

 prothorace parvo, transverso, ad latera valde et subrequaliter rotundato 

 (postice vix angustiore), angulis posticis retrorsum productis sed rotun- 

 datis, densissime ruguloso-punctato ; elytris crenato-striatis, interstitiis 

 sequalibus transversim imbricato-rugatis, punctis seneis in triplici serie 

 impressis ; antennis pedibusque nigro-piceis et (in fcemina saltern) bre- 

 vibus; tibiis intermediis (saltern in sexu fcemineo) leviter ineurvis.
