140 MADEIRAN COLEOPTERA. 
—the larger ones having a tendency to arrange themselves in 
longitudinal rows towards the suture and base. Antenne, palpi, 
and legs rufo-testaceous. 
The present very distinct and interesting Iyzobius was discovered 
in Madeira proper by Mr. Bewicke ; and it is with great pleasure that 
IT am enabled to add another well-defined representative to that small 
(though widely distributed) genus. Opposite as it is in hue from 
its common European ally, I should nevertheless have regarded the 
colour (however anomalous) as totally insufficient of ztself to erect a 
species upon,—and especially so since that of the R, litura passes (as 
is acknowledged) through many different phases, or states. Fortu- 
nately however its structural peculiarities are so strongly expressed, 
that there can be no doubt whatsoever as to its real claims; seeing 
that (apart from its singularity of sculpture, which can scarcely be 
considered as structural) its larger and more escutcheon-shaped scu- 
tellum, and its differently composed eyes (in which the lenses are 
very much more minute, numerous, and depressed than in the 
R. litura), combine in giving it a character which, when once seen, 
it is impossible to mistake. The single specimen hitherto detected 
has been presented to the British Museum collection by its captor.
