62 RHYNCHOPHORA. 
inserted as far in front of the eyes as the length of the head. Thorax dull, elongate, 
narrowed in front, strongly punctate, with a short, but remarkably deep and definite 
canaliculiform fovea at the base. Elytra with the basal region flat, sulcate, but not 
deeply so; punctuation of the sulci indistinct ; interstices narrow, flat. Front feet and 
the tip of the tibia infuscate-yellow. Middle coxee rather widely separated. 
This is not at all closely allied to any other of the species here described, but 
Mr. Champion found single examples of what appear to be three species very near to 
this in different localities. 
88. Apion altum, sp. n. 
Sat elongatum, nigrum, supra eenescens, nitidum, nudum; rostro curvato, punctato, mediocri; antennis pone 
medium rostri insertis; prothorace conico, crebre sat fortiter punctato; elytris striatis, striis remote 
punctatis, interstitiis parce obsoleteque punctatis.

Hab. Panama, Bugaba (Champion). 
Rostrum moderately stout, cylindrical, much curved, strongly punctate at the sides of 
the base, rather longer than the head and thorax; eyes small, not prominent, the interval 
between them moderately broad, coarsely punctate; antenne small, inserted behind 
the middle of the rostrum, but at a distance from the eyes equal to slightly more than 
one third of the length of the rostrum. Thorax regularly narrowed from the base to 
the apex, definitely and moderately coarsely punctate, with a larger deep puncture 
forming a minute fovea in front of the scutellum. Elytra rather elongate and more 
than usually parallel-sided, very distinctly striate; looked at from the side the inner 
margins of the striz appear to be raised, and the punctures they bear seem to extend 
over and render irregular the outer margins of the strie. 
We have received only two specimens of this distinct species. I think they are of 
the two sexes, but if so the differences are only very slight. 
34. Apion longimanum, sp. n. (Tab. III. fig. 9.) 
Sat elongatum, nigrum, subopacum, antennis pedibusque elongatis; rostro maris mediocri; prothorace lato, 
anterius fortiter angustato, fortiter punctato; elytris profunde sulcatis, interstitiis convexiusculis.

Only one male of this species has been obtained, but the species is—in that sex at 
any rate—very easy to distinguish, the antenne and legs being slender, with the club 
of the former and the basal joint of the front tarsus unusually elongate; the front 
and middle tibie are mucronate internally at the apex. The rostrum is moderately 
stout, just as long as the head and thorax, the antennal insertion slightly in front of the 
middle. ‘The eyes are not large, the interval between them moderately broad, feebly 
sculptured. ‘The thorax is very coarsely sculptured, and has a small deep fovea in
