Longicorn Coleoptera of the West India Islands. 99 
(?) Ceramhyx didymusj Oliv., Ent. iv., No. 67_, p. 125, 
pi. 23, fig. 179. 
Hab. Cuba — Havana (Poey). 
This species was taken by Thomson as the type of his 
genus Brymo, which can scarcely be considered distinct 
from Eburia. 
The head is somewhat more strongly concave between the antennal 
tubers ; the antenna longer, with first and third joints scabrous 
the eleventh joint very long. Prothorax somewhat transverse, 
rounded and unarmed at the sides in the male, armed with a short 
spine in the female . 
I suspect that it was a male of this species which 
served Olivier as the type of his Cerambyx didymus. 
The peculiar form of thorax shown in his figure exists 
in no other species known to me ; and in other 
respects his figure and description apply fairly well to 
Chevrolat^s male type.
