Longicornia of South Africa, Ye. 281 
ATYBE. 
Caput latum, vertice elevato, fronte non impressa, subquadrata. Oculi 
parvi, emarginati. Antenne remote, setaceze, subfimbriate, breves, 
articulo basali ovato, tertio elongato, quarto curvato breviore, ceteris 
brevibus. Prothorax brevis, subquadratus, lateribus muticis. Elytra 
parallela, prothorace latiora, basi cristata. Pedes breves; tars? omnes 
zquales (¢bie haud breviores), articulo ultimo non elongato. Pro- et 
meso-sterna dentata. 
I am inclined to consider this genus as intermediate between Clo- 
niocerus and Ecthea, although by no means very nearly allied to 
either. With the former it has a primd facie resemblance in outline 
and vesture ; with the latter it agrees in the elevated vertex, and in 
the setaceous antenne widely separated at the base. According to 
my views, they are all referable to the Apomecynine, a subfamily of 
Lamiide, principally characterized by their short legs and generally 
short and subulate antenne, although in the latter respect Cloniocerus 
is a remarkable exception. The species described below 1s, I believe, 
unique, and was lately sent to this country by Mr. Plant, to whom 
it is dedicated. It is now in my collection.

exceptis, albidis. 
Hab. Madagascar. 
Dark brown, with a short, close, brownish pubescence, except the 
greater part of the elytra, which are whitish, the base and apex only 
being brown, with a paler patch of the same colour at the side; head 
with two small tubers on the vertex ; antennze much shorter than the 
body, dark brown, scarcely fimbriated beneath ; prothorax about equal 
in length and breadth, rather narrower posteriorly, the sides slightly 
rounded, a pair of small pointed spines directed forwards on each side 
of the disk, and another on the anterior margin immediately in a line 
with each pair; elytra rounded at the apex, a short row of spines form- 
ing a crest at the base of each, and several small spines scattered at 
intervals over the surface, some of which have a little tuft of hair at 
the apex; legs dark brown, the proximal half of the tibize white ; body 
beneath dark brown, shining, with scattered hairs; anterior acetabula 
moderately angulated externally. Length 7 lines.
