80 INSECTA MADERENSIA. 



Bemhiditim elongatum, Dej. Spec, des Col. v. 148 (1831). 

 — , Heer, Fna Col Heh. 134 (1841). 



Habitat Maderam, vel ad ripas fluviorum vel sub lapidibus in locis humidis, toto anno frequens : in 

 Madera boreali fure ad maris litus descendit, sed in australi vix infra 1500' s. m. hactenus 

 observavT. 



B. elongated and narrow, shining, dark obscure green, and with a slightly jeneous tinge. Prothorax 

 elongate-subcordate, convex, and highly polished, much attenuated behind, the posterior angles 

 being right angles ; with a cluster of large, scattered punctures in front, and a greater number 

 across the hinder margin ; with a distinct dorsal channel ; and a small fovea on either side at the 

 base. Elytra with a slightly bluish tinge ; subcyliudrical, with the sides nearly parallel ; deeply 

 punctate-striated, the striae vanishing near the apex, which is obscurely testaceous ; each with two 

 impressed points on its disk near the third stria from the suture (of which the anterior one is 

 large and distinct, and the posterior one almost obsolete), and a rounded, submarginal, testaceous 

 patch at a considerable distance behind the apex. Antenna at base rufo-testaceous, darkly infus- 

 cated towards their apex. Legs (except the extreme base of the tibiae, which is darker) pale 

 testaceous. 



The narrow, elongated outline and subcylindi-ical body of the present Bem- 

 bidium, added to its (not posteriorly only, but) anteriorly punctured prothorax, 

 its dark green sui-face, and the pale submarginal patch with which each of its 

 elytra is ornamented at a considerable distance behind the apex, will be sufficient 

 to distinguish it, even prima facie, from the remainder of the genus here described. 

 It is a tolerably abimdant insect in Madeii-a, being widely distributed over the 

 island at intermediate and lofty elevations, and occui-ring beneath stones by the 

 edges of the streams, at nearly all seasons of the year. Towards the north it is 

 less peculiar to the mountain districts than it is in the south, being not imconmion 

 in the -sicinity of Sao Vincente and at the Forno de Cal; whereas the lowest 

 altitude at which I have hitherto observ^ed it in the latter is the Cui-ral das 

 Romeiras, above Funchal, where dm'ing the autumn of 1847 I captiu-ed it in 

 considerable profusion. It would seem to attain its maximum, however, in much 

 higher regions, being very plentiful in damp spots on the mountain-slopes imme- 

 diately below the summit of the Paul da Serra, — both on the ascent from Sao 

 Vincente, and likewise, on its north-western Kmits, towards the Fanal. It is 

 recorded ia Spain, France, S^vitzerland, Styria, and Dalmatia ; and I have seen 

 specunens, in the collection of J. B-ix, Esq. of St. Neots, which were taken in 

 Jersey.
