Genus Nesiotes, nov. gen. (PI. XIV. fig. 3.) 



Corjius fere ut in 3Iicroxylobio, sed dense squamosum, ovatum, genus 

 Acalles (Cryptorhj-nchidum) omnino simulans, supra et infra grosse 

 alutaceum (nee aliter sculpturatum), rostro apiceque ipso abdominis 

 iuferiore solis l£e\-ioribus et piuictatis ; rostro lougiore graciliore, necnon 

 ad basin (mox ante ociilos) subito transversim constricto, quasi (prima 

 facie) ibidem articulate j scrobe infra oculos desinente, et cjet. ut in 

 genere prsecedenti, sed elytris in medio protborace multo latioribus. 

 Antennce ut in Microxylobio ; sed sccqjo paulo longiore et ad apicem 

 magis clavato ; fanicitlo 5-articulato, art. Imo secuudo distincte latiore, 

 2do tertio multo (et etiam primo paulo) longiore. Pedes ut in genere 

 prpecedenti, sed dense squamosi, antici ad basin vix distantiores ; 

 femoribus muticis, paulo magis clavatis, et unco tibiali acutiore, magis 

 incurve.

The remarkable little insect for which I have been compelled to 

 erect the present genxis has, at first sight, so much the appearance 

 of a small Acalles, that (before critically overhauhng it) I had placed 

 it aside as a member of that group. On closer examination, how- 

 ever, its funiculus is composed of only five joints (instead of seven), 

 whilst there is no trace of a pectoral groove for the reception of its 

 rostrum. It is consequently excluded from the whole subfamily 

 CryptorJiynchicles by the latter circumstance alone ; whilst from the 

 Cossonides, with some of the genera of which it would agree as 

 regards the former, it is altogether remote. Its affinities are indeed 

 extremely doubtful ; but, upon the whole, I should have been in- 

 clined to suspect that the Choi ides would perhaps have received it 

 more readily than any other of Schiinherr's siibfamilies, had not Pi'of. 

 Lacordaii'e assured me that in his opinion it could not properlj^ be 

 associated with the exponents of that department. Nevertheless I 

 may add that M. Jekel concurred with me in regarding the CJiolides 

 as its most probable location,— adtUng that, when thus situated, it 

 would find a " somewhat allied neighbour, in general outline and 

 many analogous characters, in the genus rylarns, from the Cape of
