INSECTA MADERENSIA. 303 



sive plantations of Senlior D'Ornellas, which cover a considerable portion of the 

 hills to the north-east of Funchal, it is abixnclant diu-ing the autumnal and winter 

 months ; and in October of 1847 I took it in great profusion from off the stumps 

 and amongst the chippings of pine-trees at the Curral das Romeiras. It possesses 

 a wide European range, being recorded from the forests of Lapland and Archangel 

 to the Mediterranean limits. It may be at once recognised from the S. pini- 

 perda by its siiperior size and more elongated prothorax, by its darker and more 

 pubescent sm-face, unkeeled head, and by its extremely rugulose and obUquely 

 truncated elytra.

ad apicem obscurissime subtruncatis, antennis pedibusque testaceis.

H. cylindrical (though shorter and more oval than the H. ligniperda), shining, pitchy-feiTuginous, 

 and somewhat sparingly clothed with a rather long and fine pubescence, — which however is 

 neither so long nor so dense as that of the last species. Head AnA jjrothorax rather more distinctly, 

 and less densely and rugosely, punctured than in the H. piniperda ; the former with a tolerably 

 distinct central keel ; the latter somewhat acuminated and constricted (though very slightly pro- 

 duced) in front, and with a very obscurely raised and somewhat less punctured central keel. 

 Elytra of a rather paler hue than the prothorax, and with the pubescence shorter, more erect, 

 and much less dense ; sparingly rugulose (though more thickly so about the shoulders and front 

 margin), finely and very lightly striate-punctate, and with the interstices minutely, though 

 remotely punctulated, and with a longitudinal row of small tubercles down each, — which are 

 exceedingly apparent behind, though less so anteriorly, and evanescent towards the centre of the 

 lateral margins ; rounded at their extremity, having only the faintest possible tendency to oblique 

 truncation. Antenna and legs testaceous. 



A common European Sylurgus, and one which has in aU probability, like the 

 last, been natm'alized in Madeira. It may be known from the H. ligniperda by 

 its smaller size and more oval outline, by its brighter, smoother, paler and less 

 densely pubescent svirface, by its strongly keeled head, shorter prothorax, and by 

 its apically siibentire elytra. The only specimen which has come beneath my 

 observation (recently conmaunicated by T. S. Leacock, Esq. from the vicinity of 

 Funchal) corresponds Avith the ferruginous variety which is so constantly to be
