MADEIRAN COLEOPTERA. 51 
this genus, in the present Catalogue, to what I did in the Znsecta Ma- 
derensia,—allotting it to the Cucwide, instead of the Cryptophayide. 
In real truth, it is a form of very difficult location, combining some 
of the essential characteristics of these two or three immediate fami- 
hes,—with any one of which it may consequently be united, pro- 
vided we attach greater importance to those of its features which 
identify it with that particular group, than to the others. After a 
careful consideration however of its many peculiarities, I now think 
that its elevated prothoracic strizv (in which it approaches Lemo- 
phleus), in conjunction with the large and securiform termination of 
its labial palpi, in which it assimilates Psammechus and Crypta- 
morpha, and the minute fourth joint of its feet (a structure which 
obtains in the latter genus and Silvanus), are of even greater im- 
portance than those of outline and antenne, which would assign it 
to the Cryptophagide ; and I believe, therefore, that when placed in 
the present position (tending towards the Colydiade, to some of the 
members of which, both in its habits and biarticulate club, it makes 
a decided approach) it will be found, upon the whole, to be nearest 
to those species with which it has the greatest affinity. 
Regarding the name, I will merely add, that I have restored that 
of Dejean’s Catalogue,—which was adopted by Stephens (and accom- 
panied by a full generic diagnosis) in 1830. It was through an 
oversight that I did not do this in the Insecta Maderensia; and it is 
surprising that M. Redtenbacher should have applied a different title 
to it, seeing that it had been properly characterized in this country 
nearly twenty years previous to the publication of his Fauna.
