and some were also found on Cascade Estate at about 1000 feet. D. muriceus is closely 
related to D. muricatus, Woll., from Ceylon, differing from it in having the prothorax less 
elongate and, at most, very feebly sinuate at the sides, and the head less densely punctate. 
The specimen from Java in the British Museum, separated from D. muricatus as a distinct 
species, is considerably larger than Seychelles examples. 
Sub-fam. Calandrine. 
Some authors treat the Calandrids as a separate sub-family of the Curculionide, 
others include them under the Curculionine. Of the eight species examined from the 
Seychelles, one only, Hugnoristus braueri, appears to be endemic. 
. EUGNORISTUS. 
Eugnoristus Schénherr, Gen. Cure., iv. p. 848 (1838). 
The type of this genus, Calandra monacha Oliv., is from Madagascar, and various 
other species have since been described from the same country, the Comoro Is., and the 
Seychelles. They are probably all palm-feeders. 
127. Eugnoristus brauerr. (Pl. 24, fig. 47, 2.) 
Eugnoristus brauert Kolbe, Mitteil. Zool. Mus. Berlin, v. p. 47 (1910). 
Loc. Seychelles: Mahé, Silhouette. 
E. braueri was described from a single specimen from Mahé. There are 70 examples 
of it in the collection before me (and also others in the British Museum). The majority 
of the 70 specimens are from Silhouette, where they were found in the high forests near 
Mont Pot-a-eau and above Mare aux Cochons in VIII. and IX. 1908: all (or almost all) 
were found in the decayed outer leaf-bases of felled heads of an endemic palm 
(Verschaffeltia splendida); on several occasions larvee were also found in the leaf-bases, 
e.g. on Aug. 31 larvee, pupee, and adults were all found together. The insect pupates in 
a cocoon made of the fibres of the palm, similar in nature to that constructed by some 
other Calandrids. Several specimens were found in Mahé on Cascade Estate, in the 
Mare aux Cochons district, and in various other localities, but are without special record 
of habitat: and the collection also contains one specimen found in Mahé by Mr J. J. 
Lister in 1888. The variation in length is from 6—114 mm. (rostrum excluded), and the 
rostrum also is sometimes greatly elongated, especially in the female. The sexes are very 
similar, but the males may be identified by the deeply excavate first ventral seement and 
the laterally angulated basal portion of the rostrum. The posterior tibiz are closely 
fulvo-ciliate along their inner edge for more than half their length in both sexes. 
TROCHORRHOPALUS. 
Trochorhopalus Kirsch, Mittheil. Dresd. Mus., 1877, p. 156; Faust, Ann. Mus. Civ. 
Stor. Nat. Genova, xxxiv. p. 342 (1894). 
A single species has been referred to this genus, the type of which came from Java.
