new Neotropical Curculionide. 453 
bears no resemblance to Olivier’s insect, and is undoubtedly 
Jarinosus, Gyl., which is possibly a synonym of rohkri, F. ; 
it does not yet appear certain that this form is really con- 
specific with abbreviatus. 
The variety figured as comma, Boh., is doublieri, Guér. ; 
the true comma occurs in Venezuela and Trinidad, and I have 
not so far seen any specimens from the Antilles. 
The figure attributed to abbreviatus must not be coaaeded 
as ty pical of the species, for it does not agree satisfactorily 
with Linneus’s description ; his type (from. Martinique) is at 
Upsala, but I have not yet had an opportunity of examining it. 
The form described as a new variety, denudatus, Pierce, i is 
the true marginatus, Oliv., recorded only from Guadeloupe.

Pachneus citri, sp. n. 
Colour piceous, with uniform, dense, pale bluish-green 
scaling, the glitter of which is more or less obscured by a 
sparse dusting of pale yellow powder ; this powder is more 
conspicuous at the sides and base of the prothorax, along the 
lateral margins of the elytra, and in the punctures. 
3 2. Head with dense opalescent creamy scales, with a 
broad, subcostate, bare central stripe, which extends back- 
wards well beyond the eyes and bears a large round fovea at 
the narrowest part of the forehead; the eyes closer together 
than usual. Rostrum longer than broad, the gene slightly 
rounded, the dorsal outline flat from the forehead to about 
the middle of the rostrum, then sloping gently to the apex ; 
the dorsum with a bare punctate central costa and a slight 
depression on each side of it, bounded outwardly by a more 
or less distinct narrower lateral costa, the space between the 
apices of the scrobes as broad as the narrowest part of the 
forehead ; the basal half of the dorsum and the forehead bear 
numerous long, recumbent, scale-like sete in addition to the 
sealing. Antenne with joints-l and 2 of the funicle sub- 
equal, "3 much longer than 4, 4 to 7 of about equal length 
and evidently longer than broad ; the club much narrower 
than usual. © Prothorac a little shorter than the basal width, 
broadest at the base, very slightly narrowing to beyond the 
middle, and then more abruptly so (?), or more nearly 
parallel-sided (¢), the basal margin rather shallowly bi- 
sinuate, the apical margin rounded dorsally, its gular edge 
very deeply sinuate ; the upper surface moderately convex, 
slightly flattened in the middle of the basal area, with a fine 
central furrow reaching neither the base nor apex and usually 
obliterated in the middle ; the sculpturing entirely hidden by
