Coleoptera of St. Vincent, Grenada, and Grenadines. 295 
fourth joints equal in length. The punctuation of the 
elytra is sparse but very distinct, much coarser than that 
of the thorax. 
PriLopactyLa, Latr. 
Ptilodactyla humerosa.

ii., 1, p. 642. 
Hab. St. Vincent—Leeward and Windward sides. 
Evidently a common insect in St. Vincent, Mr. Smith 
having sent twenty-five examples from the island. P. 
humerosa was described from a single male specimen 
from Teapa, Mexico. The third antennal joint is shorter 
than the fourth in both sexes. The coloration of the elytra 
is constant, the pale humeral patch being always well 
defined and the suture obscure ferruginous. 
Ptilodactyla sancti-vincentis, sp. n. 
6. Oblong-elliptic, flattened above, shining, thickly clothed 
with short yellowish-cinereous pubescence; piceous or rufo- 
fuscous, the under surface, and sometimes the prothorax also, 
obscure ferruginous, the antennze fusco-testaceous, the legs testa- 
ceous. Head closely, rugulosely punctate, the eyes moderately 
large ; antennz very elongate, joints 4-10 each with a rather long, 
slender ramus, 3 stouter and slightly shorter than 4. Prothorax 
short, convex in front, the sides rounded and rapidly converging 
from about the basal third to the apex, subparallel behind, the 
hind angles acute ; the base trisinuate, finely denticulate, and with 
a short projecting tooth in the centre ; the surface rather closely, 
finely punctate. Scutellum rugulose, notched in the centre in 
front. Elytra slightly wider than the prothorax, narrowly mar- 
gined and a little rounded at the sides, the humeri obtuse ; flat- 
tened and seriate-punctate on the disc, the rest of the surface 
thickly, minutely punctate. Fifth ventral segment feebly arcuate- 
emarginate at the apex. Tarsal claws with an acute tooth extending 
to about the middle. 
Length 3-34, breadth 14-1} millim. 
Hab. St. Vincent. 
Six examples, all males. Longer and more depressed 
than P. hwmerosa, the antenne longer and with longer
