SiDi Thome J Rodriguez, cCr. 27 



A perusal of Capt. Beccliey's 'Narrative/ |)ublislied in 

 two volumes iu 1831, reveals the fact that Teneriffe was the 

 only phicc where a lauding was made during the voyage of 

 the 'Blossom ' at which Trithemis annulota was at all likely 

 to have been met with. Dr. B. P. Uvarov informs me that 

 lie has found a few Orthoptera of Beechey's in the British 

 Museum ])ui})orting to come from the Sandw^ich Islands, 

 which obviously had their origin in some locality like 

 Madeira or the Canary Islands. If my determination of the 

 two fragmentary males of Trithemis should be correct, it 

 follows with a reasonable degree of certainty that they were 

 obtained at Teneriffe in June 1825, although I have no 

 positive record before me of the occurrence of T. annulata in 

 that island. 



Although the Sandwich Islands were visited by Beechey 

 . in May 1826, it cannot be taken as certain that any of the 

 dragonflies alleged to come from that archipelago actually 

 did so. Nevertheless, it is quite likely that the series of 

 Pantalufiavescens may be correctly labelled, as the species 

 is well known in the Hawaiian Islands. It is also possible 

 that the specimens of Diplacodts bipunctata likewise came 

 from Hawaii, notwithstanding the lack of other records to 

 show that the species occurs there (see Bis, Coll. Selys, 

 Libell. p. 471, 1911, where the 'Blossom' material is cited). 

 The Asiatic species were, in all probability, gathered at 

 Loo Choo in May 1827, while the putative specimens of 

 Trithemis annulata were secured at Teneriffe early in the 

 outw'ard voyage. 



In 1915 Mr. K. Oguma published " A List of Dragonflies 

 collected by Mr Okumura from Kiushiu and Loo Choo'* 

 (Ent. ^lag., Japan, i. })p. 146-148). The text of this paper 

 is in Japanese, and Mr. S. Yamada, of the Imperial 

 University, Tokio, has kindly assisted me to se|)arate the 

 ^00 Choo records from the others. The names of fifteen 

 specie s occurring in Loo Choo have been obtained in this 

 May, namely : — Orihetrum triangular e melania, Selys, O.sahina^ 

 Drury, 0. albistylum speciosum, Uliler, Crocothemis servilia, 

 Drury, Rhyothtmis variegata imperatrix\ Selys, Pantala 

 flavescens, Fabr., Diplacodes triviahs^ Ramb., Tramea 

 chinensis^ De Geer, Deielia phaon brevistigma, Ognma, 

 Gynacantha rosenhergii^ Brauer, Anax guttatus, Burm.^ 

 A. parthenope, Selys, Ictinus fallax^ Sely-"<, Gomphvs sp., and 

 Matruna ragri pectus, Selys. It will l)e observed that 

 Mr. Oguma's list does not include all of the species in the 

 ' Blossom ^ collection which I have provisionally attributed 

 to ]jOO Choo.
