of the prothorax and the apex of the elytra with a few fine white hairs, the vestiture of the scutellum 
and under surface white, the legs with intermixed white and blackish hairs. Head sparsely, finely 
punctate, shallowly or deeply foveate between the eyes, which are moderately large and widely separated ; 
rostrum (¢ ) moderately stout, about as long as the prothorax, (Q ) slightly longer, punctato-suleate at 
the sides, smooth along the middle; antennz in both sexes inserted at some distance from the apex 
of the rostrum, long, joint 2 of the funiculus a little longer than 3, 7 rather stouter than 6, the club 
oblong-ovate. Prothorax long, cylindrical, slightly narrowed behind, very sparsely punctate, a large 
space on the flanks impunctate. Elytra elongate, convex, a little flattened on the disc anteriorly, com- 
pressed at the sides, much wider than the prothorax, widening to beyond the middle, subtruncate at 
the base, the humeri rounded externally; finely seriate-punctate, the interstices each with a scattered 
series of minute punctures. Fifth ventral segment broadly emarginate at the apex, and also more or 
less depressed along the middle, in the g. Legs elongate; femora each with a small triangular tooth ; 
anterior tibie strongly sinuate within. 
Length 7-94, breadth 23-33 millim. (¢ ¢.)

In this species the rostrum is elongate, the antenne are inserted at some distance 
from the tip in both sexes and have an oblong club, the prothorax is subcylindrical, 
the elytra are elongate and widest beyond the middle, and, the legs are long and rather 
slender, the femora with a small triangular tooth. In the type, a male, the fifth 
ventral segment is broadly depressed along the middle and emarginate at the apex, 
the depression, however, is shallower in Guatemalan examples of the same sex. The 
single specimen (¢ ) from Coban has numerous white hairs on the apical declivity of 
the elytra and a rather shorter antennal club. 
48. Otidocephalus vicinus, sp. n. 
Elongate, black, shining; clothed with long, erect, blackish sete, which on the elytra are arranged in a single 
row along each interstice, the base of the prothorax with a few fine white hairs, the vestiture of the 
scutellum and under surface white, the legs with white hairs, the anterior pair with blackish ones 
intermixed. Head sparsely punctate, faintly foveate between the eyes, which are moderately large, 
widely separated, and not very prominent; rostrum considerably shorter than the prothorax in the ¢, 
longer in the 2, punctato-sulcate at the sides, smooth along the middle; antennal club oblong-ovate. 
Prothorax long, subcylindrical, slightly narrowed behind, sparsely punctate, a space on the flanks smooth. 
Elytra elongate, much wider than the prothorax, narrower in the ¢ than in the 2, moderately convex, 
flattened on the disc anteriorly, gradually widening to, or to a little beyond, the middle, the humeri 
obliquely truncate ; finely seriate-punctate, the interstices each with a row of fine scattered punctures. 
Fifth ventral segment transversely depressed or flattened, and more or less rugulose, in the middle behind, 
and also emarginate at the apex, inthe ¢. Legs long ; femora each with a small triangular tooth ; anterior 
tibiee feebly curved, strongly sinuate within.
