336 Mr. T. V, Wollaston on Additions to Madeiran Coleoptera. 



genous and that which owes its presence to chance agencies 

 from without. Whether introduced, however, or not (for it is, 

 of course, impossible to decide this point for certain on the evi- 

 dence afforded by a solitary individual), it is clear that the species 

 must be admitted into our Catalogue ; for even if it be not 

 originally Madeiran, it has in all probability, at the least, become 

 naturalized in the island. The unique example described above 

 has been presented by Mr. Bewicke to the collection of the 

 British Museum. 



In order to draw attention to its distinctions from the Trachy- 

 pklceus scaber, to which, prima facie, it is of course a good deal 

 allied, I may just repeat that it not only wants the minute spines 

 which fringe the apices of the tibia? in that insect, but that it is 

 likewise altogether smaller and has its setre denser and longer ; 

 that its rostrum is much more abbreviated and with the lateral 

 scrobs consequently shorter (being also curved upwards, to the 

 upper margin of the eye, instead of downwards to the middle of 

 it) ; that its eyes are more prominent and its antenna} longer 

 and slenderer, with their scape more flexuose at the base, and 

 implanted towards the base of the scrobs instead of towards its 

 apex ; that its forehead, when denuded of its scales, will be seen 

 to be longitudinally strigulose ; that its pvothorax is more regu- 

 larly and closely punctured ; and that its elytra have the punc- 

 tures of their strice very much larger.

I merely record here the existence of a new and insignificant 

 Longitarsus, to be added to the list, because my friend M. E. 

 Allard, of Paris, who has paid such great attention to the Halti- 

 cidce, and to whom we are indebted for the best monograph of 

 the family which has yet been published, is desirous of including 

 it in a supplemental memoir which he is preparing. Although, 

 therefore, I drew out a careful description of it before sending it 

 to Paris, I nevertheless abstain from inserting it in this paper, 

 and will simply call attention to the fact that its discovery is due 

 to Mr. F. A. Anderson, who brushed three or four specimens of 

 it (as I am informed by Mr. Bewicke) from off grass immediately 

 outside the gate which leads into the grounds of the Palheiro, 

 on the mountains to the eastward of Funchal. One of these ex- 

 amples, which has been transmitted to me by Mr. Bewicke, has
