curve (though not so decidedly so as those of the X. punctulatus). 
Elytra finely punctured, as in the X. Zinearis, but with a very 
obscure tendency to be disposed, towards the lateral margins, in 
longitudinal rows; their apical edge somewhat translucid and 
testaceous. Antenne and tarsi brownish-ferruginous ; the basal 
joint of the former (and sometimes, apparently, the third also), 
as well as the femora and tibie, piceous. 
The present Xantholinus, which in some respects (as will be 
seen) combines the characters of the X. punctulatus and linearis, 
but which may be at once known from them by, inéer alia, its 
more remotely punctured head and the testaceous apical margin 
of its elytra, appears to agree sufficiently well with the descrip- 
tion of the X. Hesperius (from Spain and Portugal) as given by 
Erichson, to justify its being referred to that insect. Never- 
theless I should state that it does not precisely accord with the 
diagnosis; and hence I have assigned it to the X. Hesperius 
with a query, being unwilling to multiply species unnecessarily 
in a somewhat obscure group. I have detected a single specimen 
of it amongst some old insects which were taken by Mr. M. Park, 
about two or three years ago, near Funchal; and a second was 
communicated to me by Senhér Moniz, during the winter of 
1859.

ZL. black and shining. Head and prothoraz higily polished : 
the former straightly truncated behind, deeply and distinctly 
punctured at the sides (but not roughly so, the punctures 
being well-defined), and with the frontal sulci deep and distinct : 
the /atter with a longitudinal row of about eight punctures on 
either side of its disk, and with about five or six (besides some 
scattered ones near the anterior angles) arranged somewhat in a 
curve towards either edge. lytra diluted in colouring (being 
more or less piceous, and still paler towards their outer apical 
angles), finely punctured, the punctures being disposed in rows
