INSECTA MADERENSIA. 445 



Ij. ovate, exceedingly convex (especially behind, where it is considerably inflated), very highly polished, 

 and, to the naked eye, almost impunctate, — ;though minute and delicate punctures are perceptible 

 beneath a powerful lens. Head, prothorax, and base of antenrue bright rufo-testaceous. Elytra 

 and the two hinder legs of the deepest black. Body beneath (except the head and prothorax, 

 which are rufo-testaceous) deep black. Apex of antenna of a less intense black than the elytra, 

 being sometimes completely iufuscate. Four anterior legs rufo-testaceous, and more or less dusky 

 in parts, — with their tarsi always darker. 



Like the last species, the present beautiful Longitarsus is of a remarkable indi- 

 genous nature, and peculiarly attached to one of the most elegant of the native 

 plants, — the Cineraria am'ita, Herit. (=Senecio Maderensis, DeCand.) — the purple 

 clusters of Avhich form such a conspiciious feature throughout the summer months 

 on the damp perpendicular rocks of lofty elevations. It ranges from about 500 to 

 5000 feet above the sea, attaining its maximum however near the upper extremity 

 of those limits. Towards the base of the island it is of the greatest rarity, the 

 lowest position at which I have hitherto detected it being in the Rev. R. T. Lowe's 

 garden near Funchal, — where I once captured a single specimen, but could never 

 obtain more. As we ascend tlie mountains, it becomes gradually more abundant ; 

 until, at the altitude of about 4500 feet, we seldom visit a bunch of the Cineraria, 

 in full bloom, without discovering some traces of its existence. During my 

 encampment in the upland region of the Cruzinhas, in July of 1850, I might 

 have taken it by hundreds, — though scarcely ever under any other circumstances 

 than those just mentioned.

Habitat in graminosis prope urbem Funchalensem, sero autumno, sub lapidibus non infrequens. 



L. elongate-ovate, rather wide and robust, slightly convex, and shining. Head and the two kinder 

 femora, except their extreme base, black. Prothorax and elytra dirty testaceous, with more or 

 less of a brownish or olivaceous tinge ; the lattey- rather the duller of the two (with their suture 

 sometimes dusky), and minutely, though evidently, punctulated. Body beneath, except the pro- 

 thorax, blackish. Antenna at apex more or less infuscated. 



A large and weU-marked Longitarsus, — readily known by its wide and robust 

 form, })lack bead and hinder femora, and by its dirty brownish-testaceous, or 

 somewhat olivaceous, hue. It appears to be an insect of rather low range, and by 

 no means common, — the few specimens which I have taken ha\ing been isolated 

 ones, dui'iug the autumnal and early winter months, from beneath stones in the
