266 RHYNCHOPHORA. 
smooth, and clothed with a few widely scattered, semierect, white, squamiform hairs, 
the usual dark sete being absent. ‘The femoral tooth is small and narrow. The 
var.? is represented by two examples from Chilpancingo, and should perhaps be 
separated as specifically distinct. | 
71. Otidocephalus flavipilis, sp. n. 
Moderately elongate, shining, varying in colour from black, with the elytra castaneous and the antenne and legs 
in part ferruginous, to entirely ferruginous ; clothed above with long, fine, suberect, scattered, yellowish, 
bristle-like hairs, which are serially arranged on the elytra, the vestiture of the scutellum, legs, and under 
surface also yellowish, the denser pubescence at the sides of the meso- and metasternum whitish. Head 
convex, coarsely punctured above, almost smooth near the eyes, which are moderately large and somewhat 
widely separated ; rostrum shorter than the prothorax, depressed at the base above, punctato-sulcate at the 
sides, smooth along the middle. Prothorax long, globose in front, much narrowed and constricted behind, 
very sparsely punctate, the punctuation becoming coarse and close along the basal margin. Elytra 
comparatively short, somewhat gibbous, much wider than the prothorax, widening to the middle, truncate 
at the base, the humeri rounded, the surface almost smooth. Femora each with a small, acute, narrow 
tooth. Anterior tibie strongly sinuate within. 
Var.? Head almost smooth, the elytra with fewer hairs. 
Length 23-33, breadth 1-13 millim.

The almost smooth, castaneous or ferruginous elytra, the long, yellowish, suberect 
hairs of the upper surface, and the small, narrow, femoral tooth, distinguish this 
species amongst its allies. Of the fourteen specimens obtained of the typical form, 
four only are from Chiriqui, these being almost entirely ferruginous. The variety (?) 
is represented by five examples from Chiriqui, but as one of the three individuals 
obtained at Teleman is intermediate I have not ventured to name it. 
72. Otidocephalus versicolor, sp.n. (Tab. XIII. figg. 29, 29 a, 3.) 
Moderately elongate, very shining, black, the head, rostrum, antennal scape, cox, and mesosternum rufous, 
the rest of the antenne and the legs piceous ; the prothorax and the disc of the elytra with a few very 
long, erect, scattered, blackish sete, the vestiture of the scutellum, legs, and under surface white. 
Head with the upper portion convex and coarsely punctate, and separated from the lateral portion by 
a sharp ridge, quite smooth between and immediately above the eyes, which are comparatively small; 
rostrum short and very stout, barely half the length of the prothorax, depressed at the base above 
(appearing curved in profile), punctato-sulcate at the sides, smooth along the middle, the scrobes deep and 
oblique; antenne short, joints 2-7 of the funiculus very short, together about as long as the club, which 
is ovate. Prothorax elongate, globose in front, narrow and subcylindrical behind, rather closely and 
coarsely punctate, except along a narrow space down the middle, the lower part of the flanks smooth.’ 
Elytra about twice as long as, and much wider than, the prothorax, gibbous, compressed at the sides 
below the shoulders, rapidly widening to the middle and narrowing thence to the apex, the humeri 
rounded ; the surface apparently smooth (viewed under a high power the usual series of punctures are 
just visible), the sete arranged in three rows on the disc of each elytron. Legs comparatively long; 
femora each with a very short, fine tooth; anterior tibie almost straight. 
Length 34, breadth 13 millim.
