West-lndian Longicorn Coleoptera. 
restored the following name, previously made use of by 
Chevrolat in manuscript : — 
Elateropsis scabrosa , sp. n. 
= E.fuliginosuS) Chevr. (nec Fabr.), Ann. Soc. Ent. de France, 1862, 
p. 271. 
=Solenoptera scabrosa , White, Cat. Brit. Mus. Longicorma, i. p. 53. 
Nigra, subopaca ; palpis, antennis pedibusque rufo-fulvis ; pro- 
thorace dorso et elytris crebre subrugosoque punctatis. 
Long. 23-31 mm. 
Hab. Cuba, $ an( J ? • 
The females of this species are strongly and coarsely punc- 
tured on the disk of the prothorax and on the elytra. The 
antennae do not reach quite to the middle of the elytra, and 
their last joint is short, scarcely, if anything, longer than the 
preceding joint. 
The males are slightly less strongly sculptured ; their 
antennae reach beyond the middle of the elytra, and have the 
last joint distinctly longer than the preceding. 
I have already mentioned that all the specimens of E. 
lineata and E. punctata in the British Museum collection 
are females. All the specimens of E. fuliginosa, Fabr., and 
E. subpunctata , Chevr., are, on the other hand, males. 
From these facts I have been led to suspect that E. fuligi- 
nosa , Fabr., is the male of E . lineata , Linn.; and this 
suspicion has been strengthened by finding that all the white- 
striped specimens of Elateropsis in the collection of Mr. 
Alexander Fry, who very kindly sent me the whole of his 
Solenopterinae for examination, are also females, while the 
unstriped glossy specimens referable to fuliginosa and sub - 
punctata are males. I have thus seen altogether twenty-two 
specimens, all females, of the three white-banded species 
mentioned above, and eleven specimens, all males, of E . full - 
ginosa , Fabr., and its questionable variety E. subpunctata , 
Chevr. 
If it is proved to be the case that the white bands in the 
species of this genus are confined to the females, then it is 
very likely that some of the less strongly punctured speci- 
mens which I now regard as males of E . scabrosa are really 
males of E . punctata . 
In E. ebenina , Chevr., there is no marked sexual difference, 
the males having the antennae slightly longer than in the 
females, with the last joint relatively somewhat longer.
