ac magis sericeo-pubescens, labro (ut mihi videtur) bre-

LL. clavicolli) postice angustiore, necnon coleopteris magis

The single example from which the above diagnosis has 
been compiled was taken in Madeira by the late Mr. 
Bewicke, but whether near Funchal or in some more 
remote part of the island I have now no means of ascer- 
taining. In its robust, abbreviated, submoniliform an- 
tennz and rather dark ferruginous hue, the elytra with 
the exception of the shoulders being of a still obscurer 
tint, it resembles the L. axillaris ; nevertheless it appears 
to be a trifle smaller, and relatively a little shorter and 
broader than that species, and it is hkewise rather flatter 
and more thickly clothed with a coarser sericeous pubes- 
cence ; its eyes also are more prominent, its upper lip 
appears to me (judging from the only type to which I 
have access) to be decidedly shorter, its head and pro- 
thorax (the latter of which is narrower behind, as in the 
DL. clavicollis) are more distinctly punctured but less 
rugose, and its elytra are more uniformly and regularly 
(although delicately) striate, and seem to have only a 
single raised costa, namely a sublateral one, down each, 
p. 1385 (genus Sinvanvs). 
(Sp. 387) Silvanus wnidentatus. 
For this Silvanus, instead of “ unidentatus, Oliv.,” read 
bidentatus, Fab. A more critical examination of it has 
convinced me that it should be referred to the latter of 
those species, rather than (as I had concluded) to the 
former. And Imay add that the S. bidentatus differs from 
the wnidentatus in being a little larger and more coarsely 
sculptured, in its limbs being proportionately a trifle 
longer and its eyes more developed, and in its prothorax 
(which is more evidently bisulcate down the disc) being 
a little more sinuate, or less straightened, at. the sides, 
with the anterior angles a good deal more produced, and 
even the basal ones just appreciably more prominent— 
so as to occasion the prothorax to appear, relatively, a 
trifle less narrow behind. During our late sojourn in
