the frontal elevations strongly raised, narrowly transverse ; clypeus 
triangular ; terminal joint of the palpi acutely pointed ; antennz 
black, the basal four joints fulvous ; thorax transverse, about one 
half broader than long, strongly narrowed at the base, the angles 
not produced, the surface with an obsolete oblique depression at each 
side, very minutely punctured when seen under a strong lens: elytra 
widened towards the middle, extremely closely punctured, the punc- 
tuation consisting of small and still smaller punctures; each elytron 
with the following black spots—one on each shoulder, three placed 
transversely across the middle (the centre spot on the sutural margin), 
four slightly larger spots below the middle forming a semicircle, and 
one at the extreme apex of each elytron. 
Colonia Tovar. 
This species forms another addition to those constituting the 
genus Malacorhinus described by myself in the ‘ Biologia Centrali- 
Americana,’ from all of which it differs in the number and position 
of the elytral spots: the thorax in all is posteriorly narrowed, the 
tibize have a minute spine (sometimes almost invisible), the first joint 
of the posterior tarsi is as long as the following joints together, the 
claws are appendiculate, and the anterior coxal cavities are open. In 
general appearance the species of this genus resemble those of the 
genus Diabrotica, and seem to inhabit principally Central America. 
LocHMA TROPICA, Nn. sp. 
Broadly ovate, black; above dark fuscous ; head and thorax 
finely rugose ; elytra with the sutural and lateral margin and two 
narrow longitudinal coste testaceous. 
Length 23 lines. 
Head finely rugose, the sides of the vertex and the clypeus tes- 
taceous ; labrum black, shining ; antennze about half the length of the 
body, black, the third joint the longest ; thorax short and transverse, 
narrowed at the middle, the angles tuberculate, the sides rounded 
at the middle, the surface transversely depressed, finely rugose, 
fuscous, the anterior and posterior margins paler ; scutellum truncate 
at its apex, nearly black, finely rugose; elytra broader than 
the thorax, widened below the middle, rather convex, fuscous; the 
narrowly raised sutural and lateral margins, and two equally narrow 
longitudinal costz at the middle of the disk and not quite extending 
to the apex, testaceous, the interstices everywhere finely rugose and 
wrinkled ; legs black, unarmed; claws bifid; the anterior coxal 
cavities open. 
Colonia Tovar. 
This species has entirely the appearance of an Adimonia, but the 
open coxal cavities would place the insect in Weise’s genus Lochmea. 
SCHEMATIZA FUNEREA, D0. sp. 
Elongate, parallel, black; the terminal joints of the antennz 
fulvous ; the entire upper surface finely rugose, opaque; elytra with 
faint traces of lighter bands at the sides.
