370 INSECTA MADERENSIA. 



aiituinn of 1847 I captured many specimens from off tlie old vinhaticos of the 

 Cm-ral das Eomeiras, — iu a comparatively active state even by day. 



282. Atlantis australis, Woll. 

 A. eloiigato-subovatus fusco-piceus, pubc subviridesccuti-ciaerea depressa parce variegatus, prothorace 

 paruui profunde punctato^ elytris sat profuiide punctato-striatis, pilis longis suberectis moUibus 

 dense adspersis, interstitiis vix tessellatis, anteniiis brcviusciilis riifo-ferrugineis, articulo tertio 

 secundo paulo longiore. 

 Mas, pcdibus sat robustis latiusculis : tibiis iuteroicdiis apicc parum robuste armatis ; anticis iutus 

 obseurissime crenulatis, apiccm versus facillime et leviter emarginatis atque ad apicem leviter 

 incurvis ; posticis ante apicem fortiter constrictis, ad apicem subito explanatis, angulo interno 

 oblique truueato (calcaneum acutum subtriangularem pone apicem exstantem efficiente), externo 

 acuiuinato valde exstante. 

 Foem, ])aulo major; pedibus gracilioribus sed baud brevioribus, simplicibus. 

 Long. Corp. lin. 3-3|. 



Habitat in Maderje australis sylvaticis, prajsertim super folia Lauri Indices et L.faetentis in locis sub- 

 inferioribus nascentium, restate ct autumno frcquens : usque ad 800' et 700' s. ui. descendit, 

 etiam in cultis vix ab urbe Funchalensi remotis intcrduui occurrens. 



A. elongate-ovate, brovvnish-piceous, or sometimes ferruginous, and sparingly variegated with a rather 

 fine, decumbent, somewhat greenish-cinereous pubescence. Rostruni and pruthorax as in the 

 A. laurijjolens, except that the latter is rather more deeply punctured. Elytra as in the last 

 species, but even less variegated still, the anterior portion having usually scarcely any tendency 

 to be longitudinally tessellated, whilst the hinder patches also are less evident than those of that 

 insect. Antenna and leffs as in the A. luuripotens. 



Male, with the legs as in the last species, but a little longer, — the two anferiur tibi(e not quite so 

 slender; and the hinder ones rather less expanded at their extremity, and witli their inner heel 

 beak-shaped and acute, — like that of the A. nodivagans. 



Female rather larger ; with the legs slenderer, though not shorter, and simple. 



Very nearly related to the last species, with which indeed, A^'ere it not for the 

 structural characters of its male tibine, it might almost be confounded. It is 

 usuallv however of a more piccous, or brownish-piccous colour than that insect, 

 its siu'facc is even still less variegated, the iiubesceuce being of a j)aler and more 

 cinereous hue, its prothorax is rather more deeply punctured, and its legs are just 

 perceptibly longer ; whilst the liinder tibiae of its males (A\hich are not quite so 

 broadly expanded at their extremity, and have thcu- inner heel beak-shaped and 

 acute, like that of the A. noctivagans) will at once distinguish that particular sex 

 from the corresponding one of the A. laurqwtens. Its range moreover is, appa- 

 rently, lower than that of any of the preceding members of the group, since it 

 would seem to descend into the cultivated districts, and it may be occasionally 

 observed so low as 700 or 800 feet above the sea : — indeed in the summer of 1850
