Gratulidior, l\\^t. Nut. Mada;^. xxi. 1) 11 s|)ccics as occtir- 

 riiig in the JSevcliclles Islands, all mentioned in the fore- 

 going papers. Apoinecyna Jauveli is, however, registered as a 

 synonym of Pterolophia sechellartiui. 



Lastly, Kolbe, in his paper ' Die Coleopterenfauna der 

 Seychclleu/^ 1910, cnnmeratcs 12 species, the same as those 

 in Allnand's list, bnt Ajjumecyna Jauveli is regarded as a 

 disiiiict speeies. 



Tlie present collection adds no less than 12 species to 

 the list, and brings the total number of Cerambycids known 

 from the Seychelles up to 23, of which 14 or 15 ( = about 

 60 per cent.) seem to be endemic. 



The endemic species are: Macrotoma «v/y///i, Waterh. ; 

 J'iati/(/nat/tus stchellarum, Anriv.; Puradandumisfuscovittuta, 

 Auriv. ; Mia-unceinia albosiynata, Auriv., glauca, Anriv., 

 and bijasciaia, Auriv.; Ceresium alOojmbens, Fairm.; Ido- 

 brium sechellurum, Auriv. ; Obrium nitidicolle, Anriv. ; 

 Anomoderus ruyusicollisy Auriv. ; Coptops humerosa, Fairm. ; 

 Pttrolojjliia instabilis, Auriv.; Hyllisia quadncullis, Fairm., 

 and Muhencs stmijusciaia, Auriv. Trayucephula alluaudi, 

 Lameere, which also is only known from the Seychelles, 

 is ])robably only an aberration of Trayocephala varieyalu, 

 Bertol., from the mainland of Africa, and introduced. 



The non-endemic species are : Xystroctra ylobosa, 01., 

 also known from Madagascar, Mauritius, F]gypt, South 

 Asia, Java, Celebes, and the Philippine Islands; IStromutium 

 burbatum, F., widely distributed in South Asia and also 

 found in Madagascar, Mauritius, and liourbon ; Ceresium 

 Jlavipes, F. {simplex, Gyllcnh.), common from Madagascar 

 to ]S'ew Guinea and the Philippine Islands; Coptups cedifi- 

 caior, F. (Africa and S. Asia) ; Trayocephula comitessa, 

 White (S. Africa); Olenecamjdus bilobus, F. (occurs in 

 S. Asia from Ceylon to New Guinea, but is not found 

 in Madagascar or the islands adjacent to Afiica) ; Sybra 

 { = Pte/'o/o/ hia) gtminata, Klug (Madagascar), and Kxo- 

 cetitrus retiiulatus, Vairm. (Madagascar, Comoros). Nearly 

 all of these have probably been introduced in recent times 

 by human agency. 



Aldatra. — On the small island of Aldabra hitherto only 

 two species of Cerambycids were known to occur, viz. 

 Glav<yies aldahrensis described by Lin ell in 1897 from 

 Dr. Abljott's collections (Proc. U.S. Nat. ]Mus.xix. no. 1119, 

 ]). 701) and IdoLrium voeltzkoui described by Professor 

 Kolbe in his paper " Koleopteren der Aldabra-lnseln " 

 (Abhandl, Senckenb. Natuif. Ges. xxvi. 1902, ])p. 567-586; : 

 both s])ecies are known exclusively from Aldabra. The
