82 RHYNCHOPHORA. 
79. Apion juno, sp.n. (Tab. III. fig. 20.) 
Robustum, nigrum, supra cyaneum, opacum, nudum; rostro magno, rugoso; femoribus basi late rufis. 
Long. 23 millim. 
Hab. Guaremata, near the city (Champion); Panama, Volcan de Chiriqui (Champion). 
Rostrum quite as long as the head and thorax, stout, rugose, with a channel on each 
side of the upper surface extending from the front of the eye to near the extremity ; 
eyes very convex, the interval between them narrow, deeply bisulcate ; antenne inserted 
about one-fifth of the length of the rostrum in front of the eyes. Thorax large, broad 
at the base, elongate, greatly narrowed in front, and broadly constricted behind the 
anterior margin, very coarsely and very densely punctured, with a fine channel at the 
base in the middle. Elytra moderately deeply sulcate; interstices rather broad, a little 
concave. Legs black, with the basal part of the femora broadly bright red. Coxe 
bearing a good deal of white setosity, the middle pair rather widely separated. 
Three specimens were obtained of this species; it is well distinguished from all our 
others. 
80. Apion gibbosum, sp.n. (Tab. IIL. figg. 21; 21 a, profile.) 
Latum, valde convexum, opacum, rufo-brunneum, setosum, elytrorum disco griseo-signate ; pedibus flavis ; rostro 
crasso, apicem versus attenuato. 
Long. 27 millim. 
Hab. Panama, Tolé (Champion). 
Rostrum subulate, longer than the thorax, the basal portion thick, dull, setose, the 
apex black, bare for a short distance only in the male, in the female for a longer 
distance; antenne fuscous; eyes convex, very widely separated, the space between 
them only finely sculptured like the rest of the surface. Thorax large, greatly narrowed 
in front, and a little constricted behind the anterior margin, dull, obscurely punctate, 
setose, with a short fine channel in front of the base in the middle. Llytra short and 
broad, with the disc very convex, the posterior part abruptly declivous, setose, the most 
elevated part surrounded by a griseous mark, deeply sulcate, the interstices broad, flat, 
finely rugose. Legs thick, pale dull yellow; coxe and trochanters fuscous, the sides 
with much pale squamosity ; middle coxe moderately separated. 
Six specimens were obtained of this remarkable species; and we have received an 
example from Honduras which may be a variety of it, the colour being paler and the 
mark on the disc of the elytra different. 
81. Apion lentum, sp. n. (Tab. III. fig. 22.) 
Breve, convexum, parce setosum, nigrum, supra rufescens, elytrorum sutura nigricante, prothorace fere 
impunctato, elytris anguste sulcatis. 
Long. 14 millim. 
Hab. GUATEMALA (Champion).
