50 RHYNCHOPHORA. 
6. Apion erythropterum, sp.n. (Tab. III. fig. 2.) 
Angustum, opacum, nigrum, elytris rufescentibus, sutura lateribusque obscuris; tenuiter setosum, elytris ad 
basin utrinque macula minuta pubescentiz albide. 
Long. vix 2 millim. 
Hab. Mexico, Chilpancingo in Guerrero (H. H. Smith). 
Rostrum short and stout, curved, little punctate and feebly pubescent; eyes not 
prominent, moderately widely separated, delicately margined with white sete; antenne 
short, inserted very near to the eyes. Thorax small, slender, distinctly narrowed 
towards the front, moderately closely, subobsoletely punctate. Elytra deeply sulcate, 
with convex interstices. Under surface sparingly pubescent; middle coxe well sepa- 
rated. Three specimens. 
The red colour of the elytra appears to be a ready means of identifying this insect, 
which in other respects is a very obscure species. 
7. Apion egrotum, sp.n. (Tab. III. fig. 3, 2 .) 
Minutum, breviusculum, nigrum, subnitidum, fere nudum; rostro maris brevi, parum sculpturato, femine 
elongato, cylindrico, levigato, antennis basi flavo; prothorace brevi, dense fortiterque sculpturato; elytris 
sat profunde sulcatis, interstitiis planis. 
Long. 13 millim. 
Hab. Panama, Bugaba, Tolé (Champion). 
Rostrum of the male dull, somewhat finely punctate, rather thick, a little shorter than 
the head and thorax; of the female impunctate, slender, curvate, but little shining, 
a good deal longer than the head and thorax; eyes convex, rather large, the interval 
between them coarsely punctate, narrow; antenne short, obscure yellow, with the club 
dark, inserted near the base but at a rather greater distance in front of it than the 
width of the interocular space. Thorax short and broad, greatly narrowed in front, 
rugosely and coarsely punctate, with a very short channel or fovea in front of the scu- 
tellum. llytra short and broad, moderately deeply sulcate, the interstices quite flat. 
Under surface with very little setosity; middle coxe rather widely separated. 
We have received thirteen examples of this obscure little insect ; it most resembles 
A. vetustum, but is not closely allied thereto, and is readily distinguished therefrom by 
the broader head and more convex eyes, as well as by the insertion of the antenne 
nearer to the base of the rostrum. 
8. Apion guatemalenum, sp. n. 
Minus elongatum, nigrum, supra snescens, fere nudum, nitidum; rostro gracili, cylindrico, elongato ; pro- 
thorace transverso, sat crebre et fortiter punctato ; elytris anguste sed sat profunde sulcatis, interstitiis 
latis, planis. 
Long. 2 millim. 
Hab. Guatemala, El Tumbador, Cerro Zunil, San Gerénimo, Senahu (Champion). 
Rostrum elongate, slender, smooth, and shining, rather longer in the female than in
