74 INSECTA MADERENSIA. 



in the north and south of Macleii-a, at somewhat low and intermediate altitudes. 

 About half-way up the Ribeii'o de Santa Luzia, from Funchal, I have taken it in 

 considerable abundance during the spring ; and in June and July at Sao Vincente 

 and the Forno de Cal. It occurs thi-oughout the greater portion of central and 

 southern Eui'ope. The Madeiran specimens differ from their more northern 

 representatives in being a little narrower and less depressed, and in having their 

 legs and antennae not quite so robust. 



57. Bembidivun curvimanimi, iroU. (Tab. II. fig. 6.) 



B. nigrum angustiusculuin, prothorace subquadi'ato angulis posticis rectis, elytro singulo striis 

 quatuor punctatis suturam versus impresso et plagis duabus obscui-is, una magna, subhumerali et 

 altera minore subapicali, valde suflFuisis rufcscentibus ornato, antennarum basi pcdibusque testaceis. 



Long. Corp. lin. 1.

B. rather narrow, shining, and black. Prothorax longer in proportion than that of the B. Lucasii, 

 and more quadrate, the posterior angles being right angles ; with a distinct dorsal channel ; and 

 an obscure impression on either side at the base. Elytra elongate-ovate ; with foui' striae, and 

 the rudiments of a fifth, on each towards the suture, the outer ones being evanescent ; the striae 

 distinctly punctured, the sutural one being the longest, and the others gradually abbreviated, 

 though less abruptly so than in the B. Lucasii; the two impressed points (so thstinct on the disk 

 of each in that species, on the third stria from the suture) being here almost, if not altogether 

 obsolete ; each with a large, obscure, ill-defined, suflFiised, rufescent blotch near the shoulder, and 

 a smaller one, even more indistinct still, behind the apex. Antenna at base, palpi and legs testa- 

 ceous : the first ferruginous, or slightly infuscate, towards their apex : the two anterior tibite 

 suddenly bent inwards at a short distance from their extremity. 



A very peculiar and interesting little BeinbicUian, and hitherto unique, — the 

 specimen from which the above description has been compiled haA"ing been cap- 

 tured by myself in Porto Santo, at the edges of the small stream known as the 

 llibeu'o de Serra de Fora, during December 1848. It would seem to be the repre- 

 sentative of the B. Lucasii in that island, to which in some respects it is allied, 

 although abundantly distinct from it specifically. Thus, it not only recedes from 

 it, as indeed it does from all the Bemhidia here described, in the singular con- 

 struction of its anterior tibiae, which are so suddenly bent inwards at a short 

 distance from their extremity as to give the insect a most unusual appearance, 

 but it differs likewise in its minuter size, and in its narrower and more parallel 

 outline, in its total freedom from the brassy-green tinge which is there so con- 

 spicuous, in its squarer and proportionably longer prothorax, which is much less 

 narrowed bchmd, and in its elytra having two patches on each, — which are more- 

 over large (especially the humeral one), rufescent, and so extremely suffused as to
