208 Mr. T. V. Wollaston on certain Coleoptera 



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

 but gro-wing, 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. Bewieke's fourteen species, two belong to the Qeodeplmga, 

 eight to the Eliynctiopliora, and one to the LamelUcornia, Phytophaga, 

 Heteromera, 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 entii-e lot ! And if we con- 

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

 well-known genera (Calosoma, PristonycJius, Heteronychus, Longi- 

 tarsus, Opatnim, and Gydonia), and that at least three of them are 

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

 pTiora are cdl of them endemic both in species and genus — and not 

 merely " endemic," but anomalous in structui'e in proportion to the 

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

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

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

 Indeed, in the remarks under Microxyloblus, 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 BJiynchophora of this moimtain-island are (in proportion to 

 its size) both numei'ous and eccentric.
