244 RHYNCHOPHORA. 
sete, the white hairs on the elytra arranged in a double or treble row on each interstice, the vestiture of 
the under surface white. Head coarsely, rather closely punctate, sulcate between the eyes, which are 
moderately large and widely separated; rostrum stout, much shorter than the prothorax, punctato-suleate 
at the sides, smooth along the middle; antenne with joint 2 of the funiculus a little shorter than 1, 
3-7 shorter than 2, the club ovate. Prothorax long, narrowed in front and behind, closely, coarsely 
punctate, except along a narrow median space. Elytra elongate, moderately convex, much wider than 
the prothorax, widening to the middle, the humeri somewhat obliquely truncated in front; seriate- 
punctate, striate towards the suture, the interstices flat and each finely bi- or triseriate-punctate. Legs 
stout ; femora each with a large, acute, triangular tooth ; anterior tibie strongly sinuate within. 
Length 53, breadth 24, millim. ( 2.) 
Hab. Mexico, Guadalajara (fHége). 
One rather worn specimen. ‘This insect, as already noted, differs too much from 
O. villosus to be included under that species. The interstitial punctuation is very 
distinct, and it is arranged in treble rows towards the sides. The elytral sete are rigid 
and semierect. 
25. Otidocephalus foveifrons, sp.n. (Tab. XIII. figg. 16, 16 a, 6.) 
Moderately elongate, black, shining ; rather sparsely clothed with long, decumbent, white hairs, which on the 
elytra are intermixed with semierect long blackish sete: and arranged in a single or double row on each 
interstice. Head almost smooth, deeply foveate between the eyes and slightly constricted behind them, 
the eyes large and somewhat widely separated; rostrum stout, very much shorter than the prothorax, 
sulcate and rugosely punctate at the sides, smooth along the middle ; antennz with joint 2 of the funiculus 
about half the length of 1, 3-7 short, the club ovate. Prothorax long, subcylindrical, much narrowed 
behind, very sparsely, finely punctate. Elytra convex, moderately long, much wider than the prothorax, 
widening to the middle, subtruncate at the base ; finely seriate-punctate, striate towards the suture, the 
interstices flat, very minutely bi- or uniseriate-punctate. Femora each with a large, acute, triangular 
. tooth. Anterior tibie strongly sinuate within. 
Length 5-53, breadth 2-23 millim. 
Hab. Mexico, Tapachula in Chiapas (Hége), Manantial (Flohr, in Mus. Berol.). 
Three specimens. Extremely like O. canescens, but with the white pubescence less 
erect on the elytra, and there intermixed with long, blackish sete, the frontal fovea 
large and deep. 
26. Otidocephalus brevisetis, sp. n. 
Elongate, pitchy-black, shining; clothed with scattered white decumbent hairs and short, erect, stiff, blackish 
sete, the latter numerous on the elytra, serially arranged, and intermixed with flattened, coarse, 
squamiform hairs, the vestiture of the legs and under surface white. Head closely, rather coarsely 
punctate, the eyes moderately large and widely separated; rostrum a little shorter than the prothorax, 
punctato-sulcate at the sides, smooth and subcarinate along the middle; antenne with joint 2 of the 
funiculus about one-half the length of 1, 3-7 shorter, the club ovate. Prothorax long, much narrowed 
behind and slightly narrowing in front, coarsely, somewhat closely punctate. Elytra long, moderately 
convex, flattened on the disc anteriorly, much wider than the prothorax, widening to the middle, the 
humeri obliquely truncated in front and laterally prominent; seriate-punctate, striate towards the suture, 
the interstices feebly convex on the disc, and irregularly, uni- or biseriate-punctate. Legs stout; femora 
each with a rather small triangular tooth; anterior tibiz strongly sinuate within. 
Length 6, breadth 27 millim. (9.) 
Hab. Mexico, Yolos in Oaxaca (Sallé).
