central keel, but with a very short, small, and obscure foveolet 

 in the centre, between the insertion of the antennae. Pro- 

 thorax very deeply punctured (the punctures being large, and 

 not nearly so numerous as in the R. tenax), and without any in- 

 dication of a central keel ; ovate, but truncated behind, being- 

 broadest just before the extreme base. Elytra very deeply punc- 

 tate-striated (the punctures being large), and with the interstices 

 most minutely punctulated. Legs concolorous with (or perhaps 

 a little darker than) the rest of the surface. Antenna paler 

 (being bright rufo-piceous), and short, with their club much 

 smaller and more globose than that of the R. tenax. 



The single specimen from which the above description has 

 been compiled was taken near Funchal by Mr. M. Park. Its 

 comparatively narrow and very cylindric outline and deeply 

 sculptured surface, in conjunction with its darker and unmetallic 

 hue, its unkeeled rostrum, and its shorter antennae (which have 

 their club much smaller and more globose than is the case in 

 that species), will at once distinguish it from its only. Madeiran 

 ally, the R. tenax.

A solitary example of the common little 0. brunneum of Europe 

 was captured lately by Mr. M. Park near Funchal. It is an 

 insect widely distributed, being especially attached to all kinds 

 of wicker- and basket-work, on the dry wood and sticks of which 

 it feeds; so that it is peculiarly liable to accidental importation. 

 I have taken it abundantly in the island of Palm a, of the Cana- 

 ries, emerging from its perforations on the sides of the light 

 open trays in which silkworms are fed.
