III. On the Longicorn Coleoptera of the West India 
Islands, By Charles J. Gahan, M,A., F.E.S. 
[Read Dec. 5th, 1894.] 
Plate II. 
The following paper, primarily intended to serve as an 
account of the Longicornia collected for the West India 
Exploration Committee of the Royal Society and British 
Association, has been extended so as to give a complete 
list of the species of this family of Coleoptera which are 
known to occur in the West India Islands. The new 
nnd some of the less well-known forms are described. 
The synonymy generally has been revised; and notes 
are in many cases added, which, it is hoped, may be of 
use to the student in determining the species of some 
of the more difficult groups. 
The collections made on behalf of the Exploration 
Committee — by Mr. H. H. Smith in Grenada, St. 
Vincent, and a few of the neighbouring isles, and by Dr. 
Tsicholls and Mr. Ramage in Dominica — include about 
forty species of Longicornia, of which twelve are now 
described for the first time. Considering the limited 
area explored, this seems a very good proportion of the 
total number of species from the West India Islands, 
viz., 217, which are recorded in the present paper. 
Chevrolat published, in the year 1862^ a list with the 
names and descriptions of eighty species of Longicornia 
which were then known to occur in the island of Cuba. 
Messieurs Fleutiaux and Salle have recently (Ann. Soc. 
Ent. Fr., 1889) given a list of the Coleoptera of 
Guadeloupe which includes thirty-nine species of the 
same family. Much, of course, has yet to be done before 
our knowledge of the Longicorn fauna of the West 
Indies is anything like so complete as that of Central 
and North America. An attempt to draw any general 
conclusions from the nature of this fauna must, under 
the circumstances, be somewhat premature. 
Of the seventy-eight genera in which the West Indian 
Longicorns have been grouped, about twenty are not 
known to have representatives elsewhere. The species
