210 RHYNCHOPHORA. 
1. Polydrosus fuscofasciatus, sp.n. (Tab. 1X. figg. 1, 1a.) 
Oblong, piceous or ferruginous, the antennx (the club excepted) and legs ferruginous, the femora sometimes 
infuscate ; variegated with a dense clothing of small cinereous (or brownish-white) and dark brown 
scales, the latter condensed into a narrow median vitta and one or three spots on each side of the disc of 
the prothorax, and three undulate fascie on the elytra (the median fascia broad, the basal one sometimes 
reduced to a transverse patch on each elytron, and the subapical one formed by numerous coalescent 
spots), the scales on the under surface whitish and opalescent. Rostrum constricted behind the points 
of insertion of the antenne, emarginate at the tip, the nasal plate short, the scrobes short, deep, 
somewhat distant from the dilated lower margin, and visible from above. Eyes large. Antenne 
extremely slender, long, the scape reaching to the front of the prothorax, joint 2 of the funiculus 
elongate, as long as 1, 3-7 obconic and gradually decreasing in length. Prothorax subcylindrical, 
transverse. Elytra broad, comparatively short, gradually widening to the middle, inflated from near the 
base; finely punctate-striate, the interstices feebly convex. Tibie and tarsi slender. 
Length 33-43, breadth 13-1,%) millim. (2 -) 
Tab. Guaremata, San Gerdénimo, Capetillo (Champion). 
Ten specimens, probably all females. Not unlike the European P. wndatus, F. 
(tereticollis, De G.), but less elongate, with extremely slender antenne, comparatively 
short, broad, inflated elytra, &c. ‘The markings vary according to the predominance of 
the light or dark scales, but the elytra always have a common dark undulate median 
fascia, followed and preceded by a suturally interrupted light one. The deciduous 
portion of the mandibles is short, curved, and acute. P. americanus, Gyll., has some- 
what similarly marked elytra, but it is a more elongate insect, with longer scrobes, 
shorter and stouter antennee, the rostrum less constricted above, &c. 
2. Polydrosus flavonotatus, sp. n. (Tab. IX. figg. 2, 2 a.) 
Oblong, ferruginous, the antenne (the darker club excepted) and legs testaceous ; thickly clothed with small 
pale brown scales, the elytra with various paler spots, which are clustered into two interrupted fasciee— 
one, oblique, at about the middle of the disc, the other undulate and subapical, the lower surface with 
opalescent scales. Rostrum constricted behind the points of insertion of the antenne, the nasal plate 
very short, angular, the scrobes deep, descending to about as far as the lower level of the eyes, the latter 
large and prominent. Antenne slender, moderately long, joint 2 of the funiculus much shorter than 1, 
3-7 slightly decreasing in length. Prothorax transverse, subcylindrical, a little broader behind than the 
head with the eyes, feebly constricted anteriorly. Elytra gradually widening to the middle, and there 
about twice as wide as the prothorax, finely punctate-striate, the interstices somewhat convex. Legs 
slender. 
Length 8, breadth 14 millim. (@ ?) 
Hab. Guaremaa, Cerro Zunil (Champion). 
One specimen, immature, with the vestiture undisturbed. Near the Mexican 
P. partitus, but with a relatively narrower head and rostrum, the pale markings on 
the elytra edged with darker scales, the lower surface only with pale greenish scales, 
the legs more slender. | 
3. Polydrosus longicornis, sp.n. (Tab. IX. figg. 3, 3a, 3.) 
Oblong, nigro-piceous, the antenne, legs, and tip of the abdomen testaceous ; densely clothed with metallic 
golden-green scales, the elytra each with a more or less distinct, curved, transverse streak or fascia at
