APION. 57 
22. Apion gracilirostre, sp. n. (Tab. II. fig. 22.) 
Elongatum, nigrum, opacum, tenuissime setosum; rostro elongato, gracili, polito ; oculis sat prominulis ; pro- 
thorace transverso, fortiter punctato, anterius et posterius leviter transversim constricto; elytris sulcatis, 
sulcis profunde punctatis, interstitiis subconvexis. 
Long. 23 millim. 
Hab. Mexico, Amula in Guerrero in August, Chilpancingo in July (H. H. Smith) ; 
GuaTEMALA, San Gerénimo (Champion). 
Rostrum slender, without sculpture, polished, curvate, much longer than the head and 
thorax ; eyes rather prominent, a little distant from the thorax, and separated by a 
moderately wide interval ; antenne elongate, inserted about as far in front of the eyes 
as the width of the neck, the basal joint dark yellow. Thorax with coarse, rugose 
punctuation, and with a fine, short channel in front of the scutellum. Elytra deeply 
grooved, and with very definite large impressions in the grooves. Legs elongate ; 
middle coxe but little separate. 
The five examples received of this species are, I presume, all of the female sex. 
Mr. Champion procured two or three very similar specimens at Cerro Zunil, having, 
however, the sides of the rostrum punctate: these may possibly be males of A. gracili- 
rostre, but I think they are more probably females of an allied species. 
23. Apion punctulirostre, sp. n. 
Sat elongatum, nigrum, subopacum, tenuiter albido-setosum ; rostro elongato, gracili, cylindrico, punctulato ; 
prothorace anterius angustato, crebrius fortiter punctato; elytris sat profunde sulcatis, interstitiis sub- 
convexis. 
Long. 24 millim. 
Hab. Mexico, Cuernavaca in Morelos in June (H. H. Smith). 
This insect certainly comes very close to A. gracilirostre; the rostrum, however, is not 
very smooth and polished as in that species, but bears a distinct punctuation. This is 
almost all I can see of importance to distinguish the two, though A. punctulirostre is a 
little more slender, and has a distinct sprinkling of minute hairs or setosity on the 
upper surface even on the elytra. 
Two specimens. It may be well to say that there are in the collection three or four 
other individuals very closely allied to this and to 4. gracilirostre, but representing, I 
believe, as many distinct species. 
24, Apion colon, sp.n. (Tab. III. fig. 5.) 
Angustum, nigrum, subopacum, tenuiter albido-setosum, elytris ad basin utrinque albido-maculatis, pectore ad 
latera dense albido-setoso ; rostro mediocri ; prothorace subcylindrico, dense fortiter punctato ; elytris sat 
profunde sulcatis. 
Long. 2 millim. 
Hab. Mexico, Cuernavaca and Chilpancingo in June, Tepetlapa in October (#1. H. 
Smith); GuatemaLa, Zapote (Champion); Panama, Taboga Island (Champion).
