the species resembles L. bicolor, but the colour of the head and underside readily 

 separates it. In form it is also less gibbous, and at the apex more obtuse. The 

 preceding species, L. episcopalis, is also related, but this too differs in colour. 

 The males have the thorax more narrowed in front, and the sides nearly straight.

This species is readily known by the parallel prosternum, which has on each side 

 between the coxa? a distinctly impressed marginal line extending nearly round the 

 apex. The thorax is sparsely clothed with silvery-white hairs at the sides, similar 

 hairs extending on the sides of the elytra to the apex. 



12. Lissomus flavipennis.

In addition to its size and colour, which make this a conspicuous species, another 

 character is present which seems to have escaped notice. On the metasternum there 

 will be observed an elevated line beginning behind the middle coxae, curving backward, 

 then outward, and joining the suture at the side of the metasternum. All the other 

 species have but a rudiment of this line.

The species of this genus are of rather small size, usually bicoloured, or with the 

 elytra maculate or banded. Fortunately the literature is but little scattered, and is 

 either monographic or supplementary thereto, so that the identification of the species 

 is by no means difficult, although some of the characters used in their separation have 

 questionable value. 



In an examination of a large series of several species the form varies notably from 

 oblong-oval to oblong, as will be observed in D. sellatus. The basal depression can 

 hardly be relied on without accessory characters, nor has the sutural stria any value, 

 as in several species, notably D. brunneus, this stria may be either distinct or entirely 

 wanting.
