294 PERCY SLADEN TRUST EXPEDITION 



The 4 Seychelles species of Carausius form within the limits of that genus a very 

 definite group, being all of them distinguished by certain characters which separate them 

 from the other members of the genus. They are the only representatives of the large 

 tribe of the Lonchodini found outside the geographical area formed by the Oriental and 

 part of the Australasian Regions. 



On the other hand, of the Phasmidse of East Africa and Madagascar, not a single 

 representative was found in the Seychelles. 



As for the genus Grceffea, the discovery of a representative of it in the Seychelles, 

 so far removed from the centre of distribution of the genus, is a remarkable fact. (C. 

 Ferriere. ) 



Tribe Phyllini. 

 Phyllium lUiger, Kiif. Preuss. p. 499, 1798. 



1. Phyllium hioculatum Gray, in Griffith's Animal Kingdom, vol. xv. (Ins. ii.), 

 p. 191, pi. 63, fig. 3, 1832; Bolivar, Ann. Soc Ent. France, vol. Ixiv. p. 374, 1895; Brunner 

 and Redtenbacher, Die Insektenfam. der Phasm., p. 174, 1906. 



Loc. Seychelles. Silhouette, 1908 : 1 adult and 1 immature $, 1 adult and several 

 immature $. Mahe : 4 adult $, and a number of immature $ in various stages of develop- 

 ment, and eggs ; one of the adult $ was marked (when alive) with patches of reddish 

 colour on the femora, tibise, the large nervures of the tegmina, and the abdomen ; the 

 other adult ? were almost uniform green. None of the specimens were found in the high 

 mountain-forests. Also known from Mauritius, India, Ceylon, Java, Sumatra, Borneo. 



Note. Three other species of Phyllium have been recorded from the Seychelles : 

 P. gelonus Gray, also known from Ceylon and the East Indies : P. celebicum de Haan, 

 also recorded from Burmah, Philippine Is., Celebes, &c.: and P. siccifolium Linnaeus, 

 also recorded from Mauritius, India, Indo-China, Philippine Is., Moluccas, &c. : see 

 Brunner and Redtenbacher, op. cit. pp. 174, 175 and 176. None of these were obtained 

 by the Percy Sladen Trust Expedition. (C. Ferriere.) 



Tribe Lonchodini. 

 Carausius Stal, Rec. Orth. iii. p. 8, 1875. 



2. Carausius alluaudi (Bolivar). 



Lonchodes alluaudi Bolivar, Ann. Soc. Ent. France, vol. Ixiv. p. 372, 1895. 



Carausius alluaudi Brunner and Redtenbacher, Die Insektenfam. der Phasm., p. 274, 

 pl. 12, fig. 6h{$), 1907. 



The fact that the length of the intermediate femora compared with that of the 

 metanotum brings this species near to the genus Lonchodes, made me originally decide to 

 place this species in that genus rather than in Carausius. This character distinguishes 

 all the Seychelles species from the rest of the species of Carausius. Redtenbacher was 

 wrong in ascribing to this species the character " femora omnia apice subtus mutica." It 

 can be seen that I said in my original description " femora omnia inermia, tantum subtus 

 ante aream apicalem bidentata." (/. Bolivar.)
