To this species I refer a solitary specimen from Guatemala with some hesitation, 
even after comparison with the type. It shows several points of divergence from the 
latter example, now in the Chapuis collection, but is so immature as to make it hard 
to say how far these points are material or merely the result of its condition. It is a 
little less robust ; the elytra are less obtuse at the apex and more finely punctate, the 
depression appears narrower, deeper, more shining and less conspicuously squamose. 
Indeed the scales on it appear to be absent at first sight, but are seen with the 
microscope and clearly owe part of their inconspicuous character to immaturity ; 
whereas the type on the other hand is an old specimen, in which the scales form a 
more opaque and conspicuous clothing owing to the accumulation of dirt. 
The fact that the species was originally described from Brazil is of little moment; 
many of the Xylebori have an extended range, and like X. spinulosus are exported in 
articles of commerce, and not a few examples in the Chapuis collection, which bear no 
more precise indication of locality than “Brazil,” might be as usefully and perhaps 
more accurately labelled “ Tropical America.”

A single example has reached us from each locality. The species is quite distinct 
and much more like a Yomicus than are most XAylebori, on account of the denser 
pubescence, the strong punctuation of the basal half of the prothorax, and the retuse 
apex of the elytra. This is, however, shallower than in any true TYomicus, and 
has no well-defined toothed lateral border; its fundus is very closely and strongly 
punctured and hairy, and possesses a row of four or five tubercles close to the apex 
on each side.

Four examples were obtained, which agree absolutely with the type except that they 
are piceous or piceous-black in colour, the type being very immature. The species is 
easily recognized amongst American Xylebori by its colour, long and close pubescence, 
t tubercles on the front of the convex semi-elliptic prothorax, and the
