tubercle slopes back more gradually. In tlie shape and 
width of the sternal processes there seems to be complete 
agreement, as well as in the length of the first joint of 
the posterior tarsi.

Alcidion scurra, Chevr., Ann. Soc. Ent. rr._, 1862,

In outline this species resembles the last, but it is 
much less convex above, being somewhat compressed 
dorso-ventrally. It is covered with a fulvous-brown 
pubescence, with some scattered raised black points on 
the elytra. The apices are obliquely truncate. 
On account of its abbreviated form, and the absence 
of centro-basal crests from the elytra, this species will 
be better placed in Leptostylus than in the genus in 
which Chevrolat placed it. 
Leptostylus prsemorsus, Fabr. 
Lamia prsemorsa, Fabr., Ent. Syst. i., 2, p. 275 (1792). 
There are three or four very closely allied forms from 
the Antilles, one of which is no doubt the true prsemorsa 
of Fabricius ; but which one I am at present unable to 
decide. Under the circumstances I must content myself 
with pointing out their slight differences, retaining for 
them the names they bore in Dejean's collection. 
196. L. prsemorsus (Dej. Cat). 
Pubescence light brown. Prothorax with three small tubercles 
above, and one larger on each side. Elytra each with a narrow 
pale band, black-bordered behind, crossing obliquely at about the 
beginning of the posterior declivity, and forming with its fellow a 
rather wide angle, pointing forwards, at the suture ; with the 
apex obliquely and somewhat emarginately truncate. The oblique 
impression, a little behind the base of each elytron, is distinct, and 
is usually marked by a short dusky band, which gives off a shorter 
anterior branch from its inner end, so that it comes to resemble 
the letter V. Some small granules are scattered over the elvtra.
