Woll., but it is much more elongate. The 5-jointed funiculus distinguishes it from 
Rhyncolus. 
81. Pentarthrum punctatissimum, n. sp. 
Elongate, subfusiform, robust, feebly shining; piceous, the tarsi, the base of the 
antenne, and the antennal club, often ferruginous. Rostrum (¢) stout, thickened towards 
the base, feebly curved, moderately long, densely, rugosely punctate, (2) more curved, 
longer, and much more slender, subcylindrical. thickened towards the base and slightly 
widened at the tip, shining, finely punctate, rugose at the base; antennee in ? inserted 
near the base of the rostrum, in $ at about the basal third, the club small; eyes 
moderately prominent; head, the exposed part of the basal portion included, very 
rugosely punctate. Prothorax much longer than broad, subconical, strongly constricted 
before the apex, and rounded at the sides posteriorly; densely, coarsely punctate. 
Scutellum minute. Elytra as wide as the prothorax, moderately long, very gradually 
narrowing from the base in ?, subparallel in their basal third in gf, conjointly rounded and 
narrowly explanate at the apex; coarsely crenate-striate, the interstices very narrow, 
somewhat convex, and rugulose, the first (sutural) closely uniseriate-punctate. Beneath 
coarsely, densely punctate; metasternum flattened and sulcate posteriorly; ventral 
seoments 1 and 2 broadly excavate down the middle in ~. Anterior coxe narrowly 
separated. 
Length 24—3}! mm. (62). 
Loc. Seychelles: Praslin. 
Forty-two specimens, found in the leaf-bases of a growing ¢ Coco-de-mer, in the 
Vallée de Mai, on Noy. 28th, 1908. In this species the rostrum is dissimilarly formed in 
the two sexes, the antennal club is quite small, and the entire surface, above and beneath 
(including the exposed basal portion of the head), is densely, coarsely punctate. 
82. Pentarthrum seychellarum, n. sp. 
g. Elongate, subfusiform, convex, shining; piceous, the tarsi and antennze obscure 
ferruginous. Rostrum stout, feebly curved, parallel-sided, about as long as the width of 
the head with the eyes, much more finely punctured than the inter-ocular space, slightly 
depressed at the base; eyes prominent, rather large; antennee with joints 3—5 of the 
funiculus strongly transverse, the club small. Prothorax a little longer than broad, 
oblongo-conic, rounded at the sides posteriorly and feebly constricted just before the apex; 
densely, moderately coarsely punctate, except along the smooth abbreviated median line. 
Scutellum minute. Elytra moderately long, slightly wider than the prothorax, sub- 
parallel in their basal third and gradually narrowing thence to the apex, the apices not 
explanate; crenate-striate, the interstices transversely rugulose and closely uniseriate- 
punctate. Beneath closely punctate; ventral segment 1 excavate down the middle. 
Anterior tibiz sinuate, and ciliate towards the apex, within. 
Length 23 mm. 
Loc. Seychelles: Mahé. 
One specimen, from the Cascade Estate, 800—1500 feet. The parallel-sided rostrum 
and finer sculpture separate P. seychellarwm from P. punctatissimus and P. longicolle.
