Longicorn Coleoptera of tJic West India Islands. 97 
ivory spots-; with the outer spot of the basal pair very small, and 
sometimes (as in the type) reduced to the merest trace, the outer 
spot of the mid-elytral pair longer than the inner spot ; with an 
obtuse costa passing backwards from the last-mentioned spot as far 
as the top of the rather steep posterior slope of the elytron, and 
with a slight depression or channel lying between this costa and 
the sutural edge, with a somewhat similar, but longer, costa on the 
side of the elytron in its posterior two-thirds, and with a third, 
very feebly raised, and scarcely evident costa passing back from 
the outer spot of the median pair ; this costa bare of pubescence, 
and appearing as a dark line, which is also the appearance of the 
inner costa when rubbed bare of pubescence. A small patch in 
front of the middle spots is always bare of pubescence, and 
appears as a darker-coloured and strongly punctured area. Apex 
of each elytron bispinose, the sutural spine less than half as long 
as the external spine. Apices of the middle and hind femora 
bispinose, with the posterior spine of each nearly twice as long as 
the anterior. 
Chevrolat^s Ehuria duvalii was based on small uu- 
rubbed specimens from Cuba, in wbich the outer elytral 
spot of the basal pair is distinct, and in which the inner 
posterior costa, being covered with pubescence, seems to 
have escaped his observation. 
A specimen in the British Museum collection, originally 
received by Dejean from Beauvois, and ticketed Carolina, 
was considered by Chevrolat to be the type of Olivier's 
Cerambyx stigma.

Hah. Cuba and Jamaica. 
The specimen from Jamaica (Gosse coll.) which White 
described as the male of pedestris really belongs to con- 
sohrina, Duv., which may be distinguished by the struc- 
ture of its antennae. These are dark in coloration. 
The first three or four joints are (at least, in the male) 
scabrous, the first has a broad channel or depression in 
front, the third and fourth have each a feeble groove 
anteriorly, the third is scarcely as long as the fourth, the 
joints from the third to the ninth or tenth have each an 
acute angle or tooth at their lower distal end, and the
