and posterior margins broadly black ; the metastemum black, 

 with a yellowish space in front of the trochanters of each of 

 the hind legs ; the antennee, parts of the mouth, wings, and 

 legs black. Antennae moderate. Thorax with the sides broad, 

 and the middle space in front projecting triangularly over the 

 head ; anterior angles rounded, posterior slightly acute. Ely- 

 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 costje run down in the space between it 

 and the suture ; and on the outer side the elytra expand, leav- 

 ing a defined line marking the point of the expansion ; and 

 this expansion is anteriorly swollen, like the cheeks of jEoIus 

 (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 incmwed 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 sutm-al angle is 

 nearly right-angled. From the analogy of the next species, 

 L. elegans, which is nearly allied to it, I presume that 

 the apex of the elytra in the female is romided to the su- 

 ture, and not truncate, and that the sutm-e 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. Mollis ; 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 sutm-al 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 

 segment. In sliape, however, and general appearance it differs 

 more materially. It is a larger, longer, and more elegantly 

 proportioned insect. The thorax is more transverse and
