A. elongate-subovate, piceous, or brownish-piceous, and sparingly variegated with a fine, decumbent, 

 somewhat coppery-cinereous, or greenish-cinereous pubescence, — of an exceedingly variable nature, 

 but usually reflecting, when viewed obliquely, more or less of a dull metallic lustre. Rostrum 

 and prothorax as in the last species, except that the latter is usually widest about the middle 

 (instead of a little behind the middle), and is very much more densely punctured, — the punctures 

 however having generally a slight tendency to radiate as in that insect, but with the intermediate 

 ones (even under the microscope) scarcely perceptible. Elytra rather deeply punctate-striated ; 

 free from additional pile except at the extreme apex, where there are a few very short bristles, or 

 stiflF hairs ; the alternate interstices very obscurely tessellated with denser portions of the pubes- 

 cence, — occasionally however rather distinctly so behind, where the suture also is sometimes a 

 little more evidently paler, or blotched, than in most of the other species. Antenna fusco-ferru- 

 ginous, or fusco-testaceous ; their scape generally a little paler than the remainder, and rather 

 slender : the second joint of their funiculus distinctly longer than the first. Legs rather long, 

 varying from rufo-ferruginous into testaceous, and simple in both sexes : the tarsi with their 

 terminal joint rufo-testaceous. 



The A. ineonstans may be known by its comparatively large size and obscurely 

 tessellated surface (which, although of a very variable natiu-e, has generally more 

 or less of a tlull coppery or golden-green tinge when \-iewed obliquely), by its 

 densely pim^ctured prothorax, somewhat elongated legs, and by its scape being 

 rather slender at the base. In the first joint of its funiculus being distinctly 

 shorter than the second it agrees with the A. instahUis ; nevertheless its much 

 greater bviUc, longer limbs, and the less robust base of its antennae will at once 

 separate it from that insect. It is apparently peculiar to Porto Santo, where I 

 captured several specimens, diu'ing December 1848, from beneath stones on the 

 open plain of the Campo de Baxo, and in the low sandy idneyards, to the south of 

 the island, immediately behind the sea-beach.
