INSECTA MADERENSIA. 387 



bent inwards towards their apex ; very lightly punctate-striated ; without the slightest indication 

 of either additional pile or setae; and with the alternate interstices, apparently, untessellated. 

 Aniennes and tarsi (and sometimes the entire legs) brownish-feri-uginous ; the latter with their 

 tibice considerably dilated at their extremity, — the inner and outer angles being subequally 

 prominent. 



The present species, and the A. suhtessellatus, agree in their excessiyely small, 

 punctiform scutelliim, and in the comparatively slight ciu'vature of then* scape. 

 Nevertheless the A. crassus recedes from that insect in its perceptibly shorter and 

 more inflated body, in its less opake, and much less densely pubescent surface, in 

 its rather more evidently abbreviated antennse, and in the absence of any appear- 

 ance either of minute additional setae or of tessellation from its elytra. Its tibiae, 

 moreover, are much more dilated at their termination, and the anterior pair 

 (instead of being somewhat roimded off) are slightly produced at theii* outer angle, 

 — a structure which, in conjunction with the incurved interior one (which obtains 

 throughout the whole of these groups), causes theu" extremity to be unusually 

 robust and broad. It occurs beneath stones on the grassy ledges of the rocks, as 

 well as amongst lichen, in the mountains of Porto Santo, — where, in certain posi- 

 tions, it is extremely common from the begianing of the winter to the early spring. 

 Dui'Lag my residence in that island, with the Rev. "W. J. Armitage, in December 

 18J;8, I captured it in great profusion on the Pico d'Anna Ferreii-a, especially 

 towards the eastern ascent from the Campo de Baxo. 



§ II. TiUcB ad apicem minus dilatatm, anticm ad angulum externum subtruncatce. 

 A. Antennarum scaptis leviter curvatus : scutellum minutissimum punciiforme. 



296. Anemophilus subtessellatus, TT^oIl 



A. ovatus subconvexus niger, pube subcuprescenti-, vel subvii-idesceuti-cinerea subtih depress^ dense 

 variegatus, prothorace ruguloso-subpunctato, elytris leviter punctato-substriatis, setulis minu- 

 tissimis brevissimis (interdum vix observandis) rigidis erectis undique dense obsitis, interstitiis 

 alternis plus minusve obscure submaculoso-tessellatis, antennis tarsisque fusco-ferrugineis, oculis 

 minutis subdemissis. 



Long. Corp. lin. l^r-lf. 



Habitat ins. Portus Sancti, inter lichenes in rupium fissuris crescentes, una cum Anemophilo crasso 

 degens, — ab autumno usque ad ver primum vulgaris. 



A. ovate, but not quite so round or so convex as the A. crasstts ; also of a darker and less rasty hue, 

 and more densely clothed, — the pubescence moreover being of a rather more yellowish-green 

 tinge. Rostrum, prothorax, and scutellum as in that insect; except that the_^Vs/ is perhaps just 

 perceptibly longer, and the second not quite so convex or so broad in the middle : the e^Jes also 

 not quite so minute^ and a Uttle more prominent. Elytra less convex than in the last species,
