324 Mr. A. Murray on Coleoptera from Old Calabar. 
The first is that figured and described by Schénherr, under 
the name of foliaceus. It is the oblitus of Dejean ; and the male 
is easily recognized from those of the allied species by its large 
size and the great degree of expansion and inflation of the elytra, 
and by the apical black mark on the elytra not extending across 
in nearly a straight line in front, but protruding forwards in three 
more or less curved, ill-defined breaks in each, the outer black 
mark being marginal and reaching further forward than the 
two imner ones, as shown in Pl. [X. fig. 1, which represents 
the male. The suture is concave towards the apex of the 
elytra, and the sutural angle ends in an incurved sharp point, 
as shown in fig. 1, d. 
In none of the Lycide of this group is much attention to be 
paid to the colour of the underside of the body or of the limbs 
or basal articles of the antenne. In this species the underside 
is yellow, and the legs black ; but in some the body is brown; 
and in others the femora are yellowish,—considerable variation 
occurring in the depth and intensity of the colour. 
This species is usually considered the same as the next; but 
I have found the above characters pretty constant, although in 
the colouring there are undoubtedly mdications of transition 
between them, inasmuch as the anterior line of the black apical 
patch in the next species shows sometimes breaks whi if 
continued, would produce that of this species ; but I have never 
been able to find a regular uninterrupted series of gradations 
between the two. 
One argument in favour of their being distinct is that Ihave | 
only received some half dozen specimens of this species, and 
these all in one envo?, whereas in all the other collections sent 
the following species has been numerous.

Smaller than L. foliaceus, differing in the form of the black 
apical marking on the elytra, it being nearly straight in front, 
or only extending very slightly further along the margin than 
in the middle. The inflation of the elytra differs also a little 
in shape, being broadest a little behind the middle, while in 
L. foliaceus the expansion is nearly oblong oval, and widest in 
the middle. The termination of the sutural angle is different, 
being sinuate, as shown in fig. 3 6, instead of incurved as in
