APION. 49 
shining from the insertion of the antenne forwards; while in the male it is less cylin- 
drical, and only becomes shining in front. The prothorax is a good deal narrowed in 
front, not so long as it is wide at the base, with the punctures rather distant and very 
ill-defined ; it has a short obsolete channel at the base on the middle. 
4. Apion dissimilipes, sp. n. 
Parum elongatum, nigrum, peropacum, parcius minute griseo-setosum; antennis tibiisque sordide subfus- 
centibus ; rostro minus gracili; prothorace transverso, transversim bis subconstricto, parce punctato ; 
elytris brevibus, profunde sulcatis. 
Long. 1 millim. absque rostro. 
Mas tarsis intermediis articulo basali subtus mucrone armato. 
Hab, GuaTEMALA, near the city, San Geronimo (Champion). 
Rostrum in the male rather thick and about as long as head and thorax, in the 
female rather more slender and elongate; the eyes are small and very little promi- 
nent, placed very near the thorax; the antenne are short, inserted quite as far in front 
of the eyes as the width of the interocular space, they are of a dark fuscous colour, 
with the club black. ‘The thorax is rather broad and short, a good deal narrowed in 
front, very dull, with distant, rather large punctures, and in front of the scutellum 
a minute canaliculiform fovea. Elytra with the sculpture deep, the interstices narrow, 
convex. Under surface with no condensation of sete on the breast or beneath the 
orbits. 
Two pairs of this species were obtained ; the peculiar structure of the basal joint of 
the middle tarsus will enable it to be identified with certainty so far as the male sex is 
concerned. 
5. Apion nitidirostre, sp. n. 
Breve, coleopteris subglobosis, nigrum, nitidum, nudum; rostro gracili, polito; prothorace parce obsolete 
punctato ; elytris striatis. 
Long. 13 millim. 
Hab. Panama, Bugaba (Champion). 
Rostrum in the male as long as head and thorax, in the female a little longer; free 
from sculpture and very shining; eyes convex, placed very near the thorax, the interval 
between them moderately wide; antenne inserted very near to the eyes. Thorax short, 
greatly narrowed in front, sparingly and obsoletely punctate, without impression in 
front of the scutellum. Elytra short, broad and convex, finely striate. Legs short. 
A species not closely allied to any other from our region; the very shining rostrum, 
with antenne inserted near the base, the sublevigate thorax, and the finely striate elytra 
are sufficient to distinguish it. Only three specimens have been obtained.
