68 RHYNCHOPHORA. 
Only one specimen has been received. It is one of the most distinct species of the 
genus: the highly polished surface of the rostrum and thorax, the absence of grooves 
on the elytra, the form and colour, being each of them peculiar. 
47, Apion subrufum, sp. n. 
Gracile, nitidum, subnudum, nigrum, antennis, pedibus elytrisque sordide rufis, prothorace subsnescente, parce 
punctato ; rostro mediocri, polito; elytris subtiliter sulcatis. 
Long. 1? millim. 
Hab. Guatemaua, La Tinta in Vera Paz (Champion). 
Rostrum rather longer than the head and thorax, polished, cylindrical; antenne 
inserted about as far in front of the base as the width of the ocular interval, which is 
rather small, and bears a few coarse but subobsolete punctures; the eyes convex. ‘The 
thorax is slender, much narrowed to the front, sparingly punctured, without channel. 
Elytra obscure red in colour, shining, with rather fine grooves, and very flat, broad 
interstices. Middle coxee not broadly separated. Sides of the breast with a fine line 
of white setosity. Two examples. 
The peculiar reddish colour of the elytra is somewhat similar to that of A. subauratum 
and A. teapense; the former has a quite different rostrum and a peculiar setosity, and 
the latter remarkably deep definite grooves on the elytra, while in A. subrufum the sulci 
are rather fine. 
48. Apion hastifer, sp. n. 
Gracile, nigrum, nitidum, tenuissime pubescens, antennis pedibusque flavis, maris rostro anterius flavescente ; 
oculis prominulis, inter sese distantibus; rostro gracili, parte anteriore tenui, subrecto, parte basali crassiore. 
Long. 2 millim. 
Hab. Panama, Bugaba, David, San Feliz, Tolé (Champion). 
Antenne inserted about as far in front of the eyes as the width of the ocular 
interval, which is broad, the eyes being large and convex; the anterior part of the 
rostrum is slender and attenuate in front, in the male yellow, in the female black. 
Thorax slender, a little dilated in the middle so as to appear broadly but faintly 
constricted in front and behind, feebly punctate. Elytra rather finely sulcate, the 
interstices not convex. J.egs moderately long, yellow, the tarsi fuscescent, at any rate 
towards the extremity; middle coxe moderately distant. Male with a small mucro 
on the inner margin of the middle tibie at the extremity. 
We have received eight examples that I refer to A. hastifer; I am not sure, however 
but what they may belong to two or three species very closely allied, with considerable 
sexual differences in the case of each ; they vary a little in size, colour, and punctuation, 
and in the length of the legs. As this small number of examples are from four 
different localities, I can come to no positive opinion about them, but the following is 
clearly distinct.
