334 INSECTA MADERENSIA.

 Long. Corp. lin. 2. 



Habitat Maderam in locis similibus ac prsecedens, semel hactenus repertus. 



A. elougate-subovate, and rather narrow', densely clothed, as in the last species, with rusty-browu 

 scales. Rostrum with, apparently, the same sexual distinctions as in the other species. Pro- 

 thorax somewhat narrow, with an almost obsolete dorsal channel, and with two setose and tolerably 

 distinct tubercles across the central portion (the two lateral ones being obsolete) ; produced 

 and setose at the apex, where the setae have a tendency to arrange themselves into two fascicles. 

 Elytra rather deeply punctate-striated, and but slightly rounded at the sides ; with a few small 

 obscure nodules, or intcrrapted ridges, especially towards the base and behind the middle, — the 

 latter of which however are the most evident ; but apparently without any indication of a trans- 

 verse postmedial band. Antenna and leffs as in the last species. 



Likemse unique. lu its densely broA^^l, rusty surface it resembles the A. p/d- 

 verulentns : nevertheless its much smaller size, more ovate outline, diilerently 

 constructed prothorax (which is setose anteriorly, and produced as in the other 

 species, and has moreover two tolerably evident setose tubercles across its disk), in 

 conjunction with the more distinct nodules and much smaller pimctm-es of its 

 elytra, and its apparent freedom from a postmedial patch, ttiU readily serve to 

 separate it from that insect. In its habits it is in every respect similar to the 

 A. jJiili^erulentus, my only specimen haAdng been captured, from beneath a stone, 

 on the barren cliffs to the eastward of Funchal, facing the south.

 culato, ad apicem leviter setuloso ; elji;ris profunde punctato-striatis, ad latera rotundato- 

 ampliatis, carinis interruptis nodulisque majoribus subsetosis (prsesertim post medium) instructis,

Habitat prope urbem Funchalenscm Maderse, cum prsecedeiitibus ct illis \'ix frequentior. 



A. oblong-subovate, sparingly clothed with brownish scales. Rostrum as in the other species, though 

 perhaps a little longer, proportionably, in the females. Prothorax with a shallow dorsal channel, 

 and with four setose but not vciy distinct tubercles across the central portion (the inner ones of 

 which are the most evident) ; produced, but apparently only slightly setose, at the apex. Ehjtra 

 deeply punctate-striated; and with the sides rounded, rather uneven, and projecting; with 

 several large interrupted ridges and nodules (formed apparently, as in the other species, by the 

 breaking-off, the abnq)t termination, and the unequal development of the elevated alternate 

 interstices), especially towards the base and behind the middle,— the latter of which are the most 

 distinct ; and with very slight indications of a transverse, postmedial patch, common to both, a 

 little paler. Antenna and legs as in the pre\'ious species.
