MADARELLUS. 383 
10. Madarellus quadriguttatus, sp. n. 
Cuneiform, shining, black with a faint «neous lustre, the elytra each with a spot on the shoulder and another 
near the apex (almost connected along the outer part of the disc), and the antenne, tibia, and tarsi in 
part, ferruginous; the punctures on the legs and under surface each bearing a minute whitish scale. 
Head finely punctate, transversely grooved between the eyes; rostrum stout, arcuate, as long as the 
head and prothorax, closely punctate, the apical half smoother and somewhat flattened, the antenne 
inserted behind the middle. Prothorax transversely convex, rounded at the sides anteriorly, tubulate in 
front; the surface with widely scattered minute punctures, the lateral portions finely, obliquely strigose. 
Elytra rather long, subtriangular, transversely depressed at the base and at the sides before and beyond 
the middle; sharply, narrowly striate, the striew feebly punctate, the interstices smooth. Pygidium 
densely punctate. Beneath coarsely, a broad space down the middle sparsely and finely, punctate, the 
propleure obliquely strigose. Prosternum with two oblique confluent sulci. Legs rugosely punctate ; 
anterior femora with a triangular tooth; anterior tibie sinuous within. 
Length 33, breadth 13 miliim. ( 2.) 
Hab. Mexico (ex coll. Flohr). 
One specimen. Very like WZ. rufomaculatus, but with the elytra a little longer, the 
strie not so fine, the basal process of the prosternum and the median portion of the 
metasternum and abdomen very sparsely finely punctate. 
11. Madarellus levicollis, sp. n. (Tab. XIX. figg. 15, 15a, 2.) 
Cuneiform, shining, ferruginous, the elytra with the scutellar region and a transverse patch on the disc beyond 
the middle slightly infuscate; the punctures on the under surface and legs each bearing an excessively 
minute whitish scale. Head sparsely, minutely punctate, transversely grooved between the eyes; 
rostrum strongly arcuate, stout, a little longer than the head and prothorax, closely, finely punctate, the 
antennz inserted at the middle. Prothorax transversely convex, narrowly and abruptly tubulate in 
front, the sides rounded anteriorly ; smooth, the lateral portions feebly strigose. Elytra subtriangular, 
depressed at the base and at the sides before and beyond the middle; finely striate, the striz obsoletely 
punctate, the interstices smooth. Pygidium strongly transverse, densely punctate. Beneath closely, a 
broad space down the middle sparsely and finely, punctate. Prosternum with two curved sulci. Legs 
rugosely punctate; anterior femora with a triangular tooth; anterior tibie sinuous within. 
Length 23, breadth 12 millim. (@ ?) 
Hab, GuateMaua, Capetillo (Champion). 
One specimen. Distinguishable by its rufous colour, almost smooth, transversely 
convex prothorax, and finely striate, submaculate elytra, the under surface with a broad 
space down the middle sparsely punctate. 
12. Madarellus jalapanus, sp. n. 
Oblong, elliptic, shining, black, almost glabrous. Head finely punctate, transversely grooved between the 
eyes; rostrum strongly arcuate, a little longer than the head and prothorax, thickened and closely 
punctate at the base, the longer apical portion smooth and moderately stout, the antenne inserted at 
about the basal third. Prothorax transverse, gradually and arcuately narrowing from the base, 
constricted and tubulate in front; almost smooth on the disc, the lateral portions finely strigose, the 
base with a row of punctures along the margin. Llytra subtriangular, moderately long, transversely 
depressed at the base, behind the shoulders, and at about the middle of the disc; sharply striate, the 
strie obsoletely punctate, the interstices smooth. Pygidium transverse, closely punctate. Beneath, a 
broad smoother space down the middle excepted, sparsely punctate, the punctures on the sides of the
