248 RHYNCHOPHORA. 
33. Otidocephalus ericius, sp.n. (Tab. XIII. figg. 18, 18 a.) 
Moderately elongate, shining, black, the antennex (the club excepted) ferruginous; the head and prothorax 
sparsely clothed with long, fine, decumbent white pubescence, the prothorax with a few intermixed dark 
sete: in front; the elytral interstices each with a single complete, somewhat closely placed series of 
semierect, coarse, squamiform, white hairs intermixed with long, erect, fine blackish sete; the vestiture 
of the scutellum, under surface, and legs white. Head sparsely, coarsely punctate, the eyes comparatively 
small and widely separated ; rostrum stout, very much shorter than the prothorax, punctato-sulcate, 
smooth along the middle; antennz with joints 3-7 of the funiculus short, 2 slightly longer than 3, the 
club ovate. Prothorax moderately long, cylindrical, narrowed and sinuate at the sides behind, sparsely, 
coarsely punctate. Elytra convex, much wider than the prothorax, widening to the middle, subtruncate 
at the base, the humeri subtruncate in front; seriate-punctate, the interstices flat, each with a single 
row of fine punctures. Femora each with a small triangular tooth. Anterior tibie sinuate within. 
Length 7, breadth 2? millim. 
Hab. Mexico, Acapulco (Hoge). 
One specimen. In this insect the somewhat closely placed, seriately arranged, white _ : 
hairs on each of the elytral interstices are coarse and squamiform (as in O. grandis), 
the blackish sete being finer. It resembles O. fovetfrons, but is larger and more 
elongate, the head is coarsely punctured and without the deep frontal fovea, and the 
white hairs on the elytra are coarser and more rigid. 
34. Otidocephalus longicollis, sp. n. 
Elongate, somewhat conical, black, shining ; the head and prothorax clothed with very fine, scattered, blackish 
and white hairs, the elytra with a row of semiecrect, stiff, white hairs along each interstice, intermixed on 
the dorsum with fine, erect, blackish sete, the vestiture of the scutellum, legs, and under surface white, 
and that of the pygidium brown. Head sparsely punctate, faintly foveate between the eyes, which are 
moderately large and widely separated ; rostrum stout, very much shorter than the prothorax, punctato- 
suleate at the sides, smooth along the middle; joint 2 of the funiculus slightly longer than 3. Prothorax 
long, subcylindrical, a little narrowed in front and behind, sparsely, rather coarsely punctate, more or 
less transversely rugose on the disc, a large space at the sides impunctate. LElytra elongate, convex, 
flattened on the disc anteriorly, much wider than the prothorax, widening to slightly beyond the middle, 
the humeri obliquely truncated in front; finely seriate-punctate, the interstices each with a row of minute 
scattered punctures. Femora each with a small triangular tooth. Anterior tibie strongly sinuate 
within. 
Length 62-8, breadth 23-3 millim. (2?) 
Hab. Mexico, Sierra de Durango? (ex coll. Flohr), Jalapa (Hoge). 
Two specimens, probably males. ‘ More elongate than O. ericius, of the western 
coast, the prothorax transversely rugose on the disc posteriorly, the elytra more finely 
seriate-punctate, with the white hairs less squamiform and not so numerous. The 
‘ntermixed stiff white hairs throughout the entire length of the elytra, which are also 
more convex, the less elongate antennal club, &c., separate it from O. apioniformis. 
35. Otidocephalus rugicollis, sp.n. (Tab. XIII. figg. 19, 194.) 
Very elongate, somewhat conical, eneo-piceous, shining; clothed with widely scattered decumbent whitish 
hairs, the elytral interstices 1-5 each with a scattered series of rather long, blackish, suberect sete. 
Head coarsely punctate, narrowly sulcate between the eyes, which are somewhat widely separated ;
