260 Mr. Martin Jacoby’s List of the Phytophagous 
Oblong, parallel ; the head impunctate, fulvous, the frontal 
tubercles small, oblique, the carina rather broad and short; palpi 
robust, piceous; antenne not extending to the middle of the 
elytra, black, the basal joint fulvous, the third joint slightly longer 
than the fourth, this and the following joints rather robust, the 
terminal one elongate, slender ; thorax twice as broad as long, the 
sides nearly straight, the anterior angles oblique, thickened, the 
posterior margin straight, the surface rather strongly convex, 
entirely impunctate, fulvous, the basal margin with a short but 
deep perpendicular groove on each side; scutellum fulvous ; elytra 
not depressed below the base, metallic blue, evenly, finely, and 
regularly punctured in semi-regular distant rows, the punctures 
scarcely finer at the apex ; abdomen and legs black, the four anterior 
femora fulvous. 
Hab. St. Vincent—Leeward side. 
One specimen. A nearly typical Lactica, but differing 
from almost all the species of the genus in the complete 
absence of a thoracic transverse suicus; this latter in 
itself often shows modification, but scarcely ever entirely 
disappears, as in the present case. ‘I'he species cannot be 
generically separated from Lactica. 
Hermxopaaca, Foudr. 
Hermxophaga smith, sp. n. 
Black, above metallic dark blue, the basal joints of the antenne, 
tne four anterior legs, and the posterior tibize and tarsi flavous ; 
thorax with a deep transverse sulcus, impunctate ; elytra distinctly 
punctured in closely approached semi-regular rows. 
Length, 1-1; line. 
Subcylindrical ; the head impunctate on the vertex, the frontal 
tubercles linear, the carina very acute, the clypeus longitudinally 
depressed on each side ; antennze scarcely extending to the middle 
of the elytra, black, the lower four joints, and sometimes the fifth 
also, flavous; thorax about one-half broader than long, the sides 
straight at the base, rather strongly rounded and also obsoletely 
angulate before the middle, the surface convex, entirely impunctate, 
and shining, the posterior margin broadly produced at the middle, 
the base with a very deep, slightly sinuate, transverse sulcus, which 
extends to the sides but is not bounded by a lateral groove ; elytra 
with a slight depression below the base, strongly punctured in 
closely approached, semi-regular rows ; underside black ; the four
