APION. 53 
Rostrum about as long as the head and thorax, rather stout, punctate above, beneath 
deeply bisulcate in front of the insertion of the antenne; eyes not convex, the interval 
between them rather narrow, bisulcate; antenne stout, inserted much on the under 
surface, about as far in front of the eyes as the width of the interval between these. 
Thorax greatly narrowed in front, not polished, but with a silky lustre, and only remotely 
and very finely punctate, without channel or fovea. Elytra shining, deeply striate, but 
with the strize scarcely deep enough to be called sulci, deeply punctate. Legs stout. 
We have received a series of about twenty specimens of this species, but I am not 
able to distinguish the sexes with certainty; it is not likely to be confused with any 
other of our Apions, its size being much larger than that of the following species. 
14. Apion davidis, sp. n. 
Breve, nigrum, subnitidum, nudum ; rostro mediocri, maris sculpturato opaco, femine levigato, nitido; pro- 
thorace conico, transverso, sat fortiter haud dense punctato; elytris subtiliter striatis. 
Long. 2-23 millim. 
Hab. Panama, David (Champion). 
Rostrum a little attenuate in front, in the male as long as the head and thorax, in the 
female a little longer; eyes rather small and but little prominent, the interocular space 
narrow, biseriately punctate; antenne flavescent at the base, inserted near to the eyes, 
but at a greater distance from them than the width of the interocular space. ‘Thorax 
rather short and broad, very strongly narrowed in front, very definitely, but neither 
closely nor coarsely, punctate, with a minute channel in front of the scutellum. LElytra 
short and broad, somewhat deplanate at the base, very distinctly striate, the strize with 
very fine remote punctures, and thus appearing crenate. Legs short; middle coxe 
rather widely separated. Six specimens. 
15. Apion derasum, sp. n. 
Angustum, convexum, nigrum, sat nitidum, nudum; rostro mediocri, curvato; prothorace conico, parce 
obsolete punctato ; elytris leviter striatis. 
Long. 13 millim. 
Hab. Guatemata, Cerro Zunil, Aceituno (Champion); Nicaragua, Chontales 
(Janson). 
Besides differing from A. championi in its much smaller size, this insect has no 
dilatation of the basal portion of the rostrum. This organ is about as long as the head 
and thorax, only moderately stout, shining, feebly sculptured; the eyes are rather 
small, slightly convex, the interval between them moderately wide; the antenne have 
the base of the first joint yellow, they are inserted considerably behind the middle of 
the rostrum, but at a greater distance from the eyes than the width cf the interocular 
space. ‘The thorax is rather long and narrow, a good deal narrowed in front, sparingly 
and subobsoletely punctured, slightly shining, without impression in front of the
