332 Mr. T. V. Wollaston on Additions to Madeiran Coleoptera. 



acuminated, but scarcely divergent; somewhat deeply striate- 

 (or perhaps rather seriate-) punctate, and apparently ornamented 

 with a few indistinct paler lines. Legs robust ; the tibial hook 

 rather less developed than in the L. Cheirantld. Antenna pices- 

 cent at their base. 



The single specimen of Lixus from which the above descrip- 

 tion has been compiled was communicated two months ago by 

 Mr. Bewicke, who obtained it from the collection of a German 

 entomologist, Dr. Wolff, by whom it was captured, during the 

 past winter, near Funchal. Being, unfortunately, unique and 

 in a rubbed condition, it is next to impossible to decide for cer- 

 tain whether it be referable positively to the L. anguinus of 

 Mediterranean latitudes, though the generality of its characters 

 are so very similar, apparently, to those of that insect, that I 

 think it would scarcely be safe to treat it as distinct. At the 

 same time, however, I cannot but admit that in the almost 

 undivaricating apices of its elytra it does not quite accord with 

 types of the L. anguinus now before me, but agrees better with 

 the diagnosis of the L. anguicidus from Southern Europe. Never- 

 theless I think that its other features, particularly of coloration, 

 will hardly admit of its being identified with the latter. 



From the L. Cheiranihi (the only Madeiran species with which 

 it could possibly be confounded) it is abundantly different, being 

 not merely (judging from the unique example) a little smaller 

 and relatively narrower, but also less densely clothed with mi- 

 nute cinereous pubescence, and moreover less evenly so, there 

 being evident traces of paler longitudinal lines, both on its 

 elytra (which are much more produced, separately, at their 

 apices) and on either side of the disk of its pronotum. Its 

 rostrum, too, is a little longer and slenderer, and subcarinated 

 posteriorly ; its prothoracic punctures are very much larger and 

 more remote (the central ones particularly being enormous and 

 subconfiuent, so as to take the form of varioles) ; and its tibial 

 hooks are less developed. 



In the event of its being an undescribed species (which, how- 

 ever, is scarcely likely), I would propose for it the trivial name 

 of Wolffii.
