channel on the middle. Thorax broader than long, greatly rounded at the sides, feebly 
constricted near the front and near the base, densely and coarsely punctate, with a 
moderately long channel in the middle in front of the base. Elytra broad, deeply 
sulcate, with a large depression in the sulci, these depressions separated only by small 
intervals, the interstices moderately broad, rather convex, quite dull. Anterior legs 
elongate ; tibiee dilated and compressed, set with hairs along the inner margin behind ; 
middle tarsi with the second joint broad, the third very broad, its lobes divergent, so 
as to receive the very short, broad fourth joint, the claws of this latter abruptly bent 
and applied to the under surface of the joint; middle and hind tibie armed with a 
short mucro at the apex internally. 
Only one specimen of this very abnormal insect has been obtained. 
29. Apion seriatum, sp.n. (Tab. III. fig. 8.) 
Robustum, nigrum, opacum; rostro sat elongato, crassiusculo, punctato et striato; prothorace subconico, 
crebrius fortiter punctato; elytris parum profunde sulcatis, interstitiis uniseriatim punctatis. 
Long. 22 millim. 
Hab. British Honpuras, Belize (Blancaneauz). 
We have only received one specimen of this species; it is not like any other, and 
will be easily recognized by the unusual character of a punctuation on the interstices 
of the elytra. Rostrum rather longer than the head and thorax, stout, dull, punctate, 
carinate at the sides; antenne short and stout, inserted about as far in front of the 
eyes as the width of the head (including the eyes); these latter rather large, slightly 
prominent, the interval between them narrow, tricarinate. Thorax large, almost as 
broad behind as the base of the elytra, much narrowed in front, deeply and coarsely as 
well as closely punctured, with a deep distinct impression in front of the scutellum. 
Elytra quite dull, very definitely, moderately deeply grooved ; interstices very slightly 
concave, each with a series of closely placed, rather large, but obsolete punctures. 
Legs stout. Middle coxee very widely separated. 
A. seriatum is really more allied to A. juno and the species near that, all of which 
have the femora more or less variegate with red, and are consequently placed in the 
next division. 
30. Apion quercicola, sp. n. 
Angustulum, nigrum, opacum, parce griseo-setosum ; rostro gracili, maris mediocri, femine elongato; capite 
angusto et brevi, oculis haud prominulis; prothorace conico-cylindrico, crebre fortiter punctato; elytris 
elongatis, sat profunde sulcatis, sulcis profunde punctatis, interstitiis planis. 
Long. 12-2 millim. 
Hab. Mexico, near the city (Flohr). 
This insect resembles A. spretissimum and A. preditum, but the antenne are inserted 
farther in front of the base, their distance in front of the eyes being as great as the
