 elytris pone medium rotundato-ampliatis, grosse striato-punc-

 gracilibus, rufo-ferrugineis, clava obscuriore ; pedibus elongatis,

Several examples of this distinct and interesting Nesiotes 

 are contained in the St.-Helena collection of Mr. Meliiss ; and 

 the species which they represent, as pertaining to one of the 

 most characteristic and anomalous of the native groups, can- 

 not but be regarded as a very significant addition to the fauna. 

 It is considerably larger than either the N. squamosus or the 

 asperatus ; and (although but slightly shining) it differs also 

 in being less opaque and very coarsely punctured^ and in 

 being more regularly beset (in addition to the decumbent 

 scales) with longer and more robust suberect seta3. Its out- 

 line is more elongate-ovate; and its limbs are less abbreviated, 

 the first and second joints of the antennaj being especially 

 longer.

This remarkable and most interesting accession to one of 

 the most characteristic of the St.-Helena genera is due, like 

 the other species enumerated in this paper, to the indefatigable 

 researches of Mr. Meliiss ; and its excessive distinctness from 

 the four other Notioxeni which have hitherto been met witli 

 induces a similar suspicion in my mind to that which I have 

 already recorded under the equally anomalous group Microxy- 

 lobmSj that in all probability many additional exponents re- 

 main yet to be detected. At first sight, indeed, it might well
