292 CANAP.TAX COLEOPTEEA. 



viated. It is evidently extremely rai-e, — the only four specimens 

 which I have seen having been captured by myself, immediately to 

 the westward of Valverde, in the island of Hierro, on the 11th of 

 February 1858. 



468. Acalles pilula, n. sp. 



A. ovatus, lateraliter subcompressus, squamis brunneis vestitus et 

 cinereis parce irroratus ; prothorace subconico, subconvexo, pos- 

 tice vix angustato, in medio leviter nigro-setoso-bituberculato ; 

 scutello obsoleto ; elytris convexis, postice vix coarctatis et ibidem 

 valde decurvis, fascia postmedia plerumque obsoleta sed fasciculis 

 parvis setosis nigris (pniesertim pone medium) instructis ; pedibus, 

 prsesertim posticis, brevibus, obscure squamoso-variegatis. 

 Var. ft. semrnidmn [an species?]. Multo major, pedibus longioribus.

 Habitat in sylvaticis TeneriiFae et Palmse, rarissimus. 

 In its general fades, outline, and obsolete scutellum, the present 

 Acalles is very nearly allied to the Madciran A. glohnU^pennis, of which 

 it is strictly the Canarian representative ; though I believe that it 

 cannot be absolutely referred to it. With the exception of the " var. 

 /3," which is perhaps specifically distinct, it is rather smaller than 

 that insect ; its rostrum (at all events in the female sex) is a little 

 slenderer and more convex ; its prothorax is relatively narrower and 

 more conical, and when denuded of its scales will be seen to be less 

 constricted behind the apex, as also more deeply and less closely 

 punctured ; its elytra are somewhat convexer still, especially at their 

 base ; and the arrangement of its scales is not quite the same. 



The A.2y>hda seems, like most of the species, to be extremely rare, 

 and confined to sylvan and subsylvan spots of intermediate elevations. 

 I have taken it in Teneriife and Palma, — namely, at Souzal, the Agua 

 Garcia, and in the wood of La Esperanza, of the former, and in the 

 Barranco de Galga of the latter. 



469. Acalles verrucosus. 



A. lateraliter compressus, supra valde arcuatus, squamis nigrescen- 

 tibus densissime tectus et dilutioribus irroratus ; prothorace postice 

 paulo angustato, ad latera late albido-squamoso, ante medium se- 

 toso-4-tuberculato ; elytris postice paulo coarctatis sed ibidem de- 

 curvis, nodulis plurimis setosis instructis, argute sti'iato-punctatis, 

 mox pone medium macula parva obluniformi utrinque valde abbre- 

 viate albido-ornatis ; pedibus tarsorumque articulo prime elongatis, 

 tibiarum squamis erectis elongatis. — Long. corp. lin. 2^-3.
