West-Indian Longicorn Coleoptera. 
Maxillary palpi much longer than the labial, their last joint 
securiform ; the last joint of the labial suboblong. Antennas 
reaching beyond the middle of the elytra, with the joints 
from the third slightly dilated towards their apices and each 
provided with one or two poriferous pits. Prothorax about 
as long as broad, and furnished on each side with two spines 
— one just behind the middle, the other between this and the 
anterior border ; with the margin cut away obliquely in 
front of the anterior spine and sinuate between the two spines, 
as well as behind the submedian spine. Scutellum broader 
than long, slightly emarginate in the middle behind. Elytra 
very slightly and gradually narrowed towards the posterior 
extremity, each provided at the suture and at the extremity of 
the lateral margin with a small tooth ; the apical margin 
between these teeth very feebly denticulate. Prosternal pro- 
cess truncate behind and very closely applied against the 
anterior border of the mesosternal process ; the latter with a 
triangular emargination behind which receives the anterior 
termination of the metasternum. 
This genus is perhaps most nearly related to Elateropsis , 
from which it differs by the bispinose margins of the pro- 
thorax, the posteriorly truncate and non- emarginate proster- 
num, and the short and broad scutellum.

Coal-black, with the palpi and femora reddish, the tibise and 
tarsi dark chestnut ; slightly nitid on the middle of the pro- 
thorax and elytra. Prothorax uneven on the disk, strongly 
and somewhat rugosely punctured above, sparsely punctured 
underneath, with a space on the side just under the anterior 
half of the lateral margin more minutely and very closely 
punctured. Scutellum slightly concave from side to side 
sparsely punctured. Elytra very strongly and closely punc- 
tured, with the punctures increasing in size and less closely 
packed towards the base. Abdomen very glossy and very 
sparsely punctured.
