Genus ACALLES. 



Schonherr, Cure. Disp. Meth. 295 (1826). 

 Acalles cinereus, n. sp. 



A. oblongo-ovatus, squamis albido-cinereis dense tectus ; prothorace 

 subintegro fere concolore, ad apicem leviter setuloso ; elytris sat 

 profunde punctato-striatis, ad latera rotundatis, carinis interruptis 

 nodulisque majoribus subsetosis instructis, plaga communi post- 

 media albidiore obscurissima (antice in medio indistincte fusco- 

 terminata) ornatis.

Habitat in sylvaticis editioribus Maderse, a Rev. Dom. Lowe De- 

 cembri ineunte A.D. 1858 repertus. 



A. oblong-ovate, and densely clothed with whitish-cinereous 

 scales. Rostrum piceous ; opake, and very coarsely punctured, 

 in the males ; a little slenderer, shining, and less punctured in 

 the females. Prothorax rather less expanded in the middle than 

 is the case in most of the sylvan species, and with its surface 

 almost entire, there being scarcely any indications of tubercles, 

 and only a few small setae at its apex. Elytra rather deeply 

 punctate-striate ; with the interrupted ridges and nodules only 

 moderately developed ; and with a very faint and ill-defined trans- 

 verse postmedial paler patch, common to both almost suffused 

 behind, but terminated in front by a more evident brownish 

 portion, colouring the central tubercles. Limbs as in most of 

 the other species. 



A single specimen (and that a male) of this rather large and 

 almost uniformly cinereous or whitish-cinereous Acalles, which 

 has its prothorax nearly free from nodules and setae, and its 

 (slightly paler) elytral patch very obscure and ill-defined (parti- 

 cularly behind), was captured by the Rev. R. T. Lowe, during 

 our encampment at the head of the Boa Ventura, in December 

 1858, in the crevices of a dead stem of the Euphorbia mellifera, 

 at a very lofty elevation below the Boca das Torrinhas. There 

 were two more of them in company with it, but these he unfor- 

 tunately did not secure. A second example (a female) has 

 lately been communicated by Mr. Bewicke, taken by himself (I 

 believe at the Lombo das Vacas) during the summer of the fol- 

 lowing year. It belongs to the section of the genus in which 

 the scutellum is not distinguishable.
