388 INSECTA MADERENSIA. 



and not quite so abruptly shortened behind ; very lightly punctate-striated ; densely beset all 

 over with extremely minute (though robust) additional setfe, which in some specimens are only 

 perceptible when viewed obliquely ; and with the alternate interstices obscurely tessellated, or 

 dappled, especially behind. Antenrue and legs as in the last species ; except that the former are 

 just perceptibly longer, and that the /«^/er have their tibice much less dilated at their extremity, — 

 the outer apical angle moreover of the front pair being (even proportionably) less prominent. 



An equally abundant insect with the last in Porto Santo, from the autumn to 

 the early spring. It is however more peculiarly attached to lichen than that 

 species, since it occurs almost exclusively in the crevices of the weather-beaten 

 rocks, and is scarcely ever foimd beneath stones. In December of 1848 and April 

 of ISiO I observed it in literal profusion on the ascent of the Pico d'Anna 

 Ferreii-a, in company with the A. crassus, the Lichenophagus fritilliis, the Tar- 

 phius Lotoei, and the Ftimis nodulus, albopictns, and fmgilis, — in all of which the 

 hal)its have the same lichen-infesting tendency. 



B. Antennarwn scapus valde curvatus : scutellum distinctum triangulare.

A. oblongo-ovatus convexus seneo-piceus nitidus, pube senescenti-, vel flavescenti-cinerea robusta 



depressa parce variegatus, prothorace profunde punctato, elytris leviter punctulatis, obsoletissime 



striatis, pilis mollibus suberectis parcissime adspersis, antennaruin basi pedibusque fusco-ferru- 



gineis, ocuhs paulo majoribus subprominulis.

Habitat in Portu Sancto, rarissime, — sub lapidibus baud procul a basi montis Pico d'Anna Ferreira a 

 meipso repertus. 



A. ovate and convex, but rather more oblong and parallel than either of the foregoing species j brassy- 

 piceous, and shining (especially the elytra), and rather sparingly clothed with an exceedingly 

 robust, decumbent, brassy- or yellowish-cinereous pubescence. Rostrum rather broader at the 

 apex than is the case with either of the other species ; the eyes, also, a little larger and more 

 prominent. Prothorax with the sides regularly, and almost equally rounded ; decjily punctui-ed, 

 — the punctures being large and oblong, with minute rounded ones between them. Scutellum 

 very much larger than in either of the other species, and triangular. Elytra somewhat parallel 

 towards their base, and rounded behind ; with shallow punctures all over, only a portion of them 

 having a tendency (so faint as to be only just perceptible) to arrange themselves in longitudinal 

 rows ; sparingly besprinkled (the prothorax likewise) with veiy soft, suberect additional hairs ; 

 and with the alternate interstices apparently untessellated. Antenna short, with then- scape 

 much curved ; dull brownish-ferruginous, the funiculus being generally darker. Legs ferruginous, 

 with their /o(o- hiiuler tibia- only slightly dilated at their extremity, and the front pair with their 

 outer apical angle rounded off. 



A most interesting little insect, receding from the other members of the present 

 group not only in its smaller and more oblong form and less acuminated rostriuu,
