and posterior margins broadly black; the metasternum black; 
with a yellowish space in front of the trochanters of each of 
the hind legs; the antenne, parts of the mouth, wings, and 
legs black. Antennz moderate. Thorax with the sides broad, 
and the middle space in front projecting triangularly over the 
head; anterior angles rounded, posterior slightly acute. Hly- 
tra with the humeral blade short and flat, the spine or point 
in the male short, and its angle obtuse and only slightly 
curved; two strong coste run down in the space between it 
and the suture; and on the outer side the elytra expand, leay- 
ing a defined line marking the point of the expansion; and 
this expansion is anteriorly swollen, like the cheeks of A¢olus 
(whence I have derived its name), broadest before the 
middle, sloping obliquely backwards; and the black apical 
margin is as broad as this swollen portion. In the male 
the suture is incurved in its posterior half, and the apex 
of each elytron is truncate obliquely and with a slight curve — 
inwards, the outer angle rounded, and the sutural angle is 
nearly right-angled. From the analogy of the next species, 
LL. elegans, which is nearly allied to it, I presume that 
the apex of the elytra in the female is rounded to the su- 
ture, and not truncate, and that the suture is straight in the 
female. | 
A very handsome species, the rich orange-colour and deep 
black making a fine contrast. : 
Rare. I have only received two males; but I have seen 
one or two others, from the west coast of Africa, in the British 
‘Museum and other collections.

Allied to L. Aolus ; but the black margin near the apex is 
‘much narrower, and cannot be said to extend along the apex ; 
for its inner side starts from the sutural angle, and from that 
part it runs parallel to the outer margin for nearly the half of 
the elytra (less in the female than the male) ; the colouring in 
other respects is nearly the same, except that the metasternum — 
is wholly black, and the abdomen all yellow, except the last.

more materially. It is a larger, longer, and more elegantly 
proportioned insect. The thorax is more transverse and
