OTIDOCEPHALUS. 237 
9, Otidocephalus fiohri, sp. n. 
Elongate, black, shining ; somewhat thickly clothed with fine, decumbent, white pubescence only, which on the 
elytra is concentrated in a rather broad stripe along each interstice, that on 1, 3, and 5 a little narrower 
than the rest. Head somewhat closely punctate, the eyes moderately large and widely separated ; 
rostrum short and stout, very much shorter than the prothorax, rather closely punctate, sulcate laterally, 
and obsoletely carinate between the eyes anteriorly ; antennal club oblong. Prothorax moderately long, 
subcylindrical, a little narrowed behind, closely punctate. Elytra two and one-half times the length of, 
and much wider than, the prothorax, gradually widening to about the middle, the humeri obliquely 
truncated in front and somewhat swollen; punctate-striate, the interstices almost flat, 1, 38, and 5 each 
with about two, and the others with three or four, irregular rows of minute punctures. Femora each with 
a small triangular tooth. Anterior tibiw feebly curved externally and strongly sinuate within. 
Var.? Rostrum slightly longer; elytra with the pubescence a little coarser, and partly fulvous, the interstices 
each with three or four irregular rows of minute punctures. 
Length 84-84, breadth 3-37 millim. 
Hab. Mexico, Santiago Ixcuintla, Tepic (Lohr, in Mus. Berol.). 
One specimen from each locality, the individual from Tepic belonging to the 
varietal form, apparently male and female of the same species. Broader than 
O. multilineatus, the prothorax relatively longer, subcylindrical, and more closely 
punctured, the rostrum stouter, the lines of the pubescence on the elytra wider, and 
the anterior tibiz less curved. 
10. Otidocephalus tzeniatus, sp. n. 
Elongate, narrow, black, shining ; sparsely clothed with decumbent white hairs only, which on the elytra are 
rather coarse and serially arranged—a double row on each of the alternate interstices 1, 3, 5, 7, 9, and a 
single row on the others, the latter becoming obsolete from about the middle forwards. Head sparsely, 
rather coarsely punctate, not or shallowly foveate between the eyes, which are moderately large and 
widely separated ; rostrum curved, about as long as the prothorax in the ?, shorter in the ¢, punctato- 
sulcate, smooth and subcarinate along the middle; antenne long, joint 2 of the funiculus much shorter 
than 1, 3-7 shorter than 2, the club oblong-ovate. Prothorax narrow, subcylindrical, moderately long, 
a little narrowed in front and behind, very sparsely punctate. Elytra elongate, convex, flattened on the 
disc at the base, much wider than the prothorax, widening to the middle, the humeri obliquely truncate 
in front and somewhat prominent ; seriate-punctate, striate towards the suture, the interstices flat, 1, 3, 
5, 7, 9 irregularly, minutely, biseriate-punctate, the others uniseriate-punctate from about the middle to 
the apex. Legs long and comparatively slender; femora each with a small triangular tooth ; anterior 
tibiee sinuate within. 
Length 54-63, breadth 2-24 millim. (d 9.) 
Hab. Mexico, Juquila in Oaxaca (Sallé), Atlapango, Valley of Mexico (Mohr, in 
Mus. Berol.). ; 
Three specimens. A rather narrow, elongate form, with double lines of somewhat 
closely placed white hairs on the elytra, those on the interstices 2, 4, and 6 not 
reaching the base and reduced to a single row, the rostrum about as long as the 
prothorax in the female, the legs comparatively long and slender, the femoral tooth 
small. 0. teniatus approaches O. albolineatus, but is much more elongate, and has 
more slender legs, &c. The absence of the black sete on the elytra separates it from 
OQ. lineipennis.
