Loc. Seychelles: Mahé. Java, Siam, Malacca, Philippines, Borneo, Bouru, New 
Guinea, Mauritius, Christmas Island. 
Eight specimens of 7. strangulatus were obtained by Messrs Gardiner and Scott in 
Mahé. One was found in 1905; one is from near Morne Blane, ca. 1000 feet, XI. 1908; 
and six are from Cascade Estate, 800—1000 feet, I. 1909. The males may be known by 
the broadly depressed. metasternum and first ventral segment, the long fulvous cilia on 
the inner edge of the posterior tibize towards the apex, and the stouter and more velvety 
rostrum. 
CosMOPOLITES. 
Cosmopolites Chevrolat, Ann. Soc. Ent. France, (6) v. p. 289 (1885); Faust, Ann. 
Mus. Civ. Stor. Nat. Genova, xxxiv. p. 342 (1894). 
The single species referred to Cosmopolites, like Metamasius sericeus and its allies in 
Tropical America, is a destructive insect to Musaceous plants in the east. It appears to 
be known in the Seychelles as the banana-weevil. Chevrolat also includes Brazil in its 
distribution, possibly in error. 
129. Cosmopolites sordidus: 
Calandra sordida Germ., Ins. Spec. Nov., i. p. 299. 
Sphenophorus sordidus Gyll., in Schénh., Gen. Curc., iv. p. 925; Kolbe, Mitteil.

Cosmopolites sordidus Chevr., Ann. Soc. Ent. France, 1885, p. 290; Faust, Ann. 
Mus. Civ. Stor. Nat. Genova, xxxiv. p. 340 (1894). 
Sphenophorus cribricollis Walk., Ann. Mag. Nat. Hist., (3) iv. p. 218 (1859). 
Loc. Seychelles: Praslin, Mahé. Réunion, Java, Burma, India, Ceylon, Andaman 
Islands, Malacca, Saigon, China, Sunda, Fiji. 
The majority of the Seychelles specimens are from Praslin, XI. 1908. Examples 
were also found in Mahé at various places in 1905 and 1908—9. Many were found 
in fallen and rotting stems of banana-trees. The long series before me from the Seychelles 
vary from 7$—11 mm. in length, exclusive of the rostrum. The sexes are very similar, 
but the male may be identified by the broadly hollowed first ventral segment. 
PoLytus. 
Polytus Faust, Ann. Mus. Civ. Stor. Nat. Genova, xxxiv. p. 353 (1894)*. 
A monotypic genus, the type of which is Sctophilus mellerborgii, Boh. (= Calandra 
remota, Sharp), from Java, the Hawaiian Is., &c. The insect has doubtless been intro- 
duced into the Seychelles, as well as into the Hawaiian Islands. 
* Erratum.—tIn the second line of Faust’s diagnosis for “septimi” read “sexti.”
