258 ‘RHYNCHOPHORA. 
11. Otidocephalus albolineatus, sp.n. (Tab. XIII. figg. 7, 7 a.) 
Moderately elongate, black, shining; clothed with decumbent white hairs only, which on the elytra are 
arranged in a double or treble row on each interstice, except on 2, 4, and 6, these having a single 
incomplete row running from about the middle to the apex. Head rather coarsely punctate, sulcate 
between the eyes, which are large and somewhat widely separated; rostrum very stout, much shorter 
than the prothorax, rugosely punctate, smooth along the middle. Prothorax moderately long, sub- 
cylindrical, much narrowed behind, somewhat coarsely punctate, except down the middle and on two 
oblong spaces on each side, which are quite smooth. Elytra wider than the prothorax, widening to 
about the middle, subtruncate at the base, the humeri obtuse ; somewhat coarsely punctate-striate, the 
interstices almost flat, 2, 4, and 6 from about the middle to the apex uniseriately, and the others from 
the base to the apex bi- or triseriately, punctate. Legs rather short; femora each with a small, narrow 
tooth ; anterior tibize sinuate within ; tarsal claws feebly appendiculate. 
Length 43-52, breadth 2-23 millim. (<.) 
Hab. Mexico, Ventanas in Durango (Hége), Valley of Mexico (Flohr, in Mus. Berol.). 
Two specimens. The chief characters of this species are the lineate arrangement 
of the pubescence on the elytra, the interstices 2, 4, and 6 becoming glabrous and 
impunctate towards the base, the peculiar sculpture of the prothorax (the smooth 
spaces being separated by a rather coarse, close punctuation), the small femoral tooth, 
and the complete absence of erect sete, the whole of the vestiture being white and 
decumbent. It has much less elongate elytra than O. multilineatus. 
12. Otidocephalus canescens, sp. n. 
Moderately elongate, black, shining; clothed with semierect, long, white hairs only, which on the elytra are 
somewhat closely placed and arranged in a single or double row on each interstice. Head smooth, 
deeply foveate between the eyes, and slightly constricted behind them, the eyes large, prominent, and 
rather widely separated ; rostrum stout, very much shorter than the prothorax, sulcate and rugosely 
punctate at the sides, smooth along the middle. Prothorax subcylindrical, moderately elongate, 
narrowed behind, very sparsely, irregularly punctate. Elytra convex, much wider than the prothorax, 
widening to the middle, subtruncate at the base; punctate-striate, the interstices flat at the sides, feebly 
convex on the disc, minutely bi- or uniseriate-punctate from the base to the apex. JFemora each with a 
large triangular tooth. Anterior tibia strongly sinuate within. 
"Length 5-52, breadth 2-21 millim. . 
Hab. Mexico, Acapulco (Hége; Flohr, in Mus. Berol.), Tlaltizapan (Flohr, in Mus. 
Berol.). : 
Three specimens. This species resembles 0. albolineatus in general facies, differing 
from it, however, in the much longer and more erect pubescence, the smooth, deeply 
foveate head, the very sparsely punctured prothorax, the uniformly seriate-punctate 
elytral interstices, and the large femoral tooth. The complete absence of the blackish 
sete on the elytra separates it at once from 0. foveifrons. 
13. Otidocephalus vestitus, sp.n. (Tab. XIIL. figs. 8, 8a, b, 3.) 
Otidocephalus vestitus, Jekel, in litt. 
Moderately elongate, robust, black, the elytra with a faint brassy lustre; densely clothed with intermixed 
brown and white, adpressed, radiato-pectinate scales, the head, prothorax, and elytra also with an
