230 RHYNCHOPHORA. 
space on each side, the rest of their surface, like that of the prothorax, being some- 
what thickly clothed with whitish pubescence. It is of the same narrow shape as 
P. albocinctus. 
15. Piazorrhinus curtus, sp. n. 
Short-ovate, dull, the elytra somewhat shining ; black, the elytra with a brassy lustre, the antenne piceous 
with the funiculus ferruginous, the tarsi rufo-testaceous ; sparsely clothed with grey pubescence, which 
on the elytra is here and there concentrated, and shows a tendency to form an interrupted angulated 
fascia before the middle, the vestiture of the scutellum white. Head sparsely punctate, the eyes very 
large and narrowly separated; rostrum stout, very short, not longer than the eyes, rugulosely punctate, 
smoother and shining at the tip; antenne very short, the club ovate, about as long as joints 2-7 of the 
funiculus. Prothorax transverse, subconical, closely punctate ; the disc feebly carinate towards the base. 
Elytra short, transversely convex, much wider than the prothorax, subparallel in their basal third, the 
humeri not prominent, obliquely truncate in front ; deeply punctate-striate, the interstices narrow, 
convex, and roughly punctulate. Legs short and moderately stout, the femora each with an excessively 
minute tooth. | 
Length 1%, breadth 1j millim. (d.) 
Hab. Panama, Pefia Blanca (Champion). 
One specimen. Shorter in form than P. cingulatus and its allies, the legs shorter 
and stouter, the antenne very short, the elytral pubescence irregularly and more 
widely distributed, but showing a tendency to form an angulated fascia before the 
middle. Narrower and more ovate than P. rugulosus, the prothorax conical in shape, 
the femoral tooth scarcely visible, the coloration and vestiture very different. 
Group OTIDOCEPHALINA. 
Otidocephalides, Lacordaire. 
The three known genera of this subfamily are all American *: Otidocephalus, 
widely distributed, but with its headquarters in Mexico; Oopterinus ft, confined, so far 
as at present known, to the United States, Mexico, and Guatemala; and Lemomerus f, 
to Peru. 
OTIDOCEPHALUS. 
Otiocephalus, Chevrolat, Ann. Soc. Ent. Fr. 1832, p. 100. 
Otidocephalus, Chevrolat, op. cit. p. 442; 1877, p. 174; 1879, p. 12; Lacordaire, Gen. Col. vi. 
p. 569; Horn, Proc. Am. Phil. Soe. xiii. p. 448; Casey, Ann. N. York Acad. Sci. vi. p. 426. 
Cycotida, Pascoe, Journ. Linn. Soc., Zool. xi. p. 453 (1873). 
This is one of the most characteristic genera of Curculionine in Central America, 
* There is probably some mistake as to the habitat of Cycotida lineata, Pase. (= Otidocephalus viitatus, 
Horn), the insect being Californian and not Australian. 
+ Dr. Horn [Proe. Calif. Acad. Sci. (2) v. p. 255 (1895)] rejected this genus as synonymous with Otido- 
cephalus ; but it will be more convenient to retain it, the species being apterous or incapable of flight. 
+ This genus, the type of which I have seen, is described as being without a scutellum, but this is a 
mistake, a minute scutellum being visible. The insect has prominent humeri, a long, exserted head, 
evanescent scrobes, a very peculiarly shaped prothorax, and fully developed wings.
