It is somewhat remarkable tliat a large array of individuals 

 now before me, collected at St. Helena by Mr. Melliss, should 

 belong entirely to a new representative of the present group, 

 quite distinct specifically from the little Nesiotes which was 

 found by Mr. Bewicke, and that thus a second member has 

 been added to one of the most interesting and truly indigenous 

 • of the island forms. The 'prima facie aspect of the N. asperatus 

 is still more suggestive, than even that of the N. squamosus, of a 

 minute Acalles ; but, as already pointed out, its total want of 

 a pectoral groove separates it, independently of all other cha- 

 racters, from the whole department of the Cryptorhynchides. 

 It is very much narrower and more oblong (in proportion to 

 its size) than the N. squamosus, its elytra, even in their widest 

 part (a little behind the middle), being scarcely if at all broader 

 than the prothorax ; and its sm-face is not only more densely 

 covered with brown mud-like scales, and intermixed with 

 short erect setae (which I do not observe in my two examples 

 of its ally), but likewise studded (as will be seen when the 

 clothing is removed) with robust granuliform tubercles, which 

 entirely cover the somewhat uneven prothorax, but which on 

 the elytra are distributed in wide (more or less anteriorly con- 

 fluent) longitudinal spaces. The second joint also of its funi- 

 culus is appreciably shorter than that of the N. squamosus, 

 being, perhaps, if anything, more abbreviated than the basal 

 one ; and its body is coarsely and closely punctured beneath. 



Both the present species and the preceding one are most 

 unmistakably indigenous at St. Helena, being without doubt 

 amongst the most characteristic of the aboriginal forms ; and 

 I believe that I was informed by Mr. Melliss that his examples 

 of the iV. asperatus were taken, for the most part, amongst and 

 beneath fallen leaves at a rather high elevation.
