LONGITARSUS, 299 
L. ovipennis differs from the other species with ovately-shaped elytra from our region 
by the dark piceous colour of the upperside. The thorax is slightly broader than 
long, a little narrowed at the base, and entirely impunctate; the elytra are strongly 
narrowed posteriorly, finely and rather remotely punctured; the antenne are about 
two-thirds the length of the body, and are more or less fuscous from the fourth or fifth 
joint. L. oopterus, Har., from Colombia, seems to be a very closely allied species, but 
it is described as being of a pale castaneous colour. 
3 (Bs). Longitarsus haroldi. 
Obscure fulvous; the basal and the sixth to the ninth joints of the antennew black, the other joints flavous ; 
thorax finely rugose-punctate; elytra ovate, closely and irregularly punctured. 
Length 1 line. . 
Head impunctate, without frontal tubercles, the labrum piceous; antenne not more than half the length of the 
body, the intermediate joints rather broad, these and the basal one black, the other joints flavous, the third 
and fourth joints equal; thorax subquadrate, slightly broader than long, the sides straight, the surface 
finely rugose-punctate towards the base, the punctures somewhat elongate in shape; elytra widened at the 
middle, convex, the punctuation more distinct than that of the thorax, irregular; the pygidium prominent ; 
the underside darker than above ; legs flavous. 
Hab. Mexico, Teapa in Tabasco (H. H. Smith). 
One specimen. This species may be known from its allies by the colour of the 
antenne and the ovately-shaped elytra. It is apparently apterous. 
7 (a). Longitarsus amulensis. 
Obscure testaceous, winged; the terminal joints of the antenne more or less fuscous; head impunctate; 
thorax scarcely perceptibly punctured ; elytra broader at the base than the thorax, irregularly and more 
distinctly punctured. 
Length ? line. 
Of somewhat subquadrate shape, gradually narrowed posteriorly, pale brownish in colour; the head impunctate, 
with an oblique groove over the eyes, the frontal tubercles obsolete, the carina short and connected with the 
clypeus ; antenne two-thirds the length of the body, the first joint long and curved, the second joint as 
stout as and nearly half the length of the first, the third shorter, the fourth and fifth joints more elongate, 
the apical ones more or less fuscous; thorax rather strongly transverse, the anterior angles oblique and 
forming an angle nearly as far down as the middle; elytra. broader at the base than the thorax, the 
shoulders distinct but not prominent, very closely and finely punctured, the punctuation becoming obsolete 
near the apex; the first joint of the posterior tarsi scarcely equalling half the length of the tibia. 
Hab. Mexico, Amula in Guerrero (H. H. Smith). 
Closely allied to L. colombicus, but less elongate; the head without a transverse 
ridge between the eyes, the antenne with much shorter joints, and the thorax nearly 
impunctate. 
8 (a). Longitarsus teapensis. 
Oblong, scarcely narrowed posteriorly, winged; below pieeous, above obscure dark brown; antenne black, the 
lower three joints fulvous; thorax impunctate ; elytra distinctly and irregularly punctured ; legs testaceous, 
the femora slightly darker. 
Length ? line.
