Several examples of this little Microxylohius are amongst 

 Mr. Melliss's Coleoptera ; and as it was also found by the late 

 Mr. Bewicke during his few hours' visit to the summit of the 

 island in 1860, there is sufficient reason to conclude that it is 

 not uncommon in the higher districts at St. Helena. In size 

 it appears to be scarcely larger than the vestitus and West- 

 woodii ; but it is altogether more robust and deeply sculptured, 

 blacker and more opaque ; its rostrum is thicker and more 

 triangular, its punctation is much more demise (as well as 

 coarser), its limbs are stronger and more incrassated, its out- 

 line is a little more ovate or rounded outwards behind the 

 middle of the elytra, and the latter are confusedly roughened 

 with small indistinct tubercles placed in longitudinal rows, 

 the interstices between which are slightly elevated and studded 

 (in unrubbed specimens) with a row of excessively short and 

 infinitesimal cinereous hairs, which, however, without a power- 

 ful glass are barely visible. Although rather difficult of obser- 

 vation, I lay considerable stress upon this last-mentioned cha- 

 racter, because, ivith the exception of the M. vestitus^ I have no 

 evidence (even whilst suspecting that it may be found to exist 

 in Chevrolat's M. Westwoodii) that there are even traces of 

 pubescence on the other members of the group. 



38. Microxylohius lucifugus. 



M. fusiformis, crassus, niger (immaturus picescens), subnitidus, 

 calvus, punctatissimus ; capita rostroque confertim et profunde 

 punctatis, hoc crasso et (praesertim in masculis) subtriangulari, 

 ad apicem in medio leviter depresso ; prothorace amplo, longius- 

 culo, ad latera rotundato, convexo, confertim profunde et argute 

 punctato; elytris (rarius obsoletissime subsenescentibus) subcon-
