CANARIAN COLEOPTERA. 287 



460. Acalles xerampelinus. 



A. elongato-suboblongus, angustuliis, squamis flavo- (vel etiam rufo-) 

 bruuneis densissime tectus ; prothorace postice vix angustato, ante 

 medium leviter setoso-bituberculato; elytris postice longissime pro- 

 ductis anguste coarctatis, carinis vix interruptis nodulisque dnobus 

 parvis nigrosetosis pone medium instructis, longe ante apicem fascia 

 angusta bastata albida (ad utrumque latus antrorsum recto pro- 

 ducta, intus argute nigro-terminata sed extus plus minus suftusa) 

 ornatis; pedibus robustis, squamoso-concoloribus. — Long. corp. 

 lin. 2-3. 



Habitat Teneriffam sylvaticam, in herbidis humidiusculis captus. 



In its rather straightened body, which however is very much drawn 

 out, or acuminated, behind, as well as in its more or less yellowish- 

 (or even reddish-) brown surface, which (in unrubbed specimens) has 

 merely the ordinary postmedial paler fascia of its elytra narrow and 

 hastate but nevertheless 2:)ro(luced anteriorly on either side in a straight 

 line (it being, also, abruptly bounded i^iternally by blacker scales, 

 whilst externally it is more or less suffused, or gradually shaded off), 

 this Acalles has such a singular appearance that it cannot possibly be 

 confounded with any of the other species here enumerated. Although 

 thickly coated with mud-like scales, it is less setose than perhaps any 

 of its Canarian allies, some rigid bristles at the apex of its prothorax 

 and two small darker fasciculi which clothe the minute nodules on 

 the hinder disc of its elytra being almost the only conspicuous ones. 

 Its ridges, or alternate interstices, are but very slightly raised, and 

 hardly at all interrupted ; and its legs, which are densely squamose, 

 are concolorous with the rest of the surface — not being annulated 

 with black. 



The A. xerampelinus is extremely rare, and apparently confined 

 to the sylvan districts of the intermediate elevations of Teneriffe. I 

 have brushed it, sparingly, from out of the rank vegetation in damp 

 spots, at the Agua Garcia, as well as in the laurel-woods on the 

 mountains above Taganana. 



461. Acalles nubilosus,n. sp. 



A. squamis brunneis et albido-brunneis densissime variegatus ; pro- 

 thorace postice vix angustato, ante medium leviter setoso-bitu- 

 berculato ; elytris postice productis coarctatis, carinis interruptis 

 nodulisque duobus parvis nigro-setosis pone medium instructis, 

 ante apicem fascia hastata albidiore (intiis in medio argute ter- 

 minata, sed postice fere in apicem pallidiorem suffusa) ornatis ; 

 pedibus squamoso-variegatis. — Long. corp. lin. If- 2^. 



Habitat in lauretis editioribus Teneriffe, rarissimus.
