58 RHYNCHOPHORA. 
Rostrum about as long as the head and thorax, dull, rather slender, a little thicker 
at the base; antenne inserted about as far in front of the base as the width of the 
interval between the eyes, the basal joint yellow; eyes rather large, but only slightly 
prominent, the orbit delicately margined with white cilize above, more coarsely so 
below; interocular space moderately broad, striate; neck rather elongate. Thorax 
slender, subcylindrical, but still a good deal narrowed in front, coarsely, deeply, and 
very closely punctate, with an obscure canaliculiform impression in front of the 
scutellum. Elytra long and narrow, moderately deeply and broadly sulcate, the 
interstices nearly flat, at the base on each side with some conspicuous white sete 
placed chiefly on the third interstice. Sides of the breast quite white with hairs. 
This species will be recognized by the narrow form, black colour, and the white 
hairs at the base of the elytra on each side. Five specimens have been received from 
Mexico, one from each of the localities more to the south: these latter examples 
have the white hairs on the elytra less conspicuous, and they may not belong to the 
same species. 
25. Apion laminatum, sp.n. (Tab. III. figg. 6; 6a, profile of head.) 
Nigrum, opacum, parcissime setosum ; rostro sat crasso, subtus lamina elongata munito; elytris sat profunde 
punctatis, interstitiis planis. 
Long. 27 millim. 
Hab. Mexico, Amula in Guerrero 6000 feet, in September (/7. H. Smith). 
We have only received one example of this species, but it has the structure of the 
rostrum so peculiar that I have thought proper to describe it. Possibly the character may 
be confined to one sex, which in that case may prove to be the male, as this example 
has a small mucro at the inner margin of the apex of the middle tibia. The rostrum 
is scarcely so long as the head and thorax, rather stout and curvate, and is provided 
beneath with a large lamina extending from the insertion of the antenne to the apex ; 
the antenne are short, quite black, with unusually abrupt club, and are inserted very 
near to the eyes; these latter are moderately large and are separated by a wide interval. 
The thorax is rather small and narrow, much narrowed in front, closely and coarsely 
punctured, with a very short inconspicuous channel in front of the scutellum. The 
elytra are rather narrow, somewhat deeply but not broadly sulcate. The clothing of 
the surface is very inconspicuous. 
26. Apion vetustum, sp. n. 
Minor, breviusculum, nigrum, subopacum, fere nudum ; rostro parum elongato, sculpturato ; capite angusto ; 
prothorace dense fortiterque punctato ; elytris leviter sulcatis, interstitiis planis. 
Long. 1? millim. 
Hab. Mexico, Teapa in January and February, Tierra Colorada in Guerrero in 
October, Rincon in September (Z. H. Smith) ; Guaremaua, San Gerénimo (Champion).
