Tramea rofienhergii^ Brauer, and Anax guttatus, Bnrm. 

 According- to Ris's monograph of the Libellolinae, the single 

 male Tramea sliould be referred to as T. limbata, Desj., d. 

 The wing-markings are identical with those of males from 

 Lombok with which I have compared them. 



Next to the fact that these dragonflies Avere casnal visitors 

 to a coral atoll several hundred miles away from the nearest 

 mainland, the chief point oF interest about them is the 

 discovery that what Kirby called Anax guttatus is really 

 Anax [Hemianax] papuensis, Burm., a species of which no 

 undoubted records exist outside the limits of the Australian 

 contiuent. As extending the known distribution of this 

 insect in the opposite direction, it may be mentioned that 

 the British Museum series includes a male presented by 

 Mr. W. Wykeham Perry, of H.M.S. ' Pearl," and taken 

 60 miles off Lord Howe's Island on 15th September, 1874, 

 when a strong wind was blowing off the island. It may be 

 added that M. Rene Martin has recorded Anax papuensis 

 from New Guinea, on the authority of a single male speci- 

 men in De Selys's collection (Coll. Selys, ^sch. p. 29, 1908). 

 M . G. Severin, however, has been kind enough to inform me 

 (i/* /i/^., 28. vi. 22) that the collection in question contains 

 no such specimen from New Guinea. There are two 

 examples labelled New Holland, and it is probable that one 

 of those labels was misread by Martin as referring to New 

 Guinea. Burmeister's type also came from New Holland, 

 and the specific name papuensis w^as evidently a misnomer 

 from the first. 



Loo Choo. 



Scattered through the National Collection are a few 

 Odonata obtained by Capt. F. W. Beechey during the voyage 

 of H.M.S. 'Blossom' to the Pacific and Behring^s Straits 

 in 1825-28. Some of these specimens are provided with an 

 oblong label inscribed " Loo Choo " and a round ticket 

 bearing simply Capt. Beechey 's name, while other specimens 

 carry nothing- beyond a round ticket marked " Sandw. L, 

 Beechey.'' The so-called Sandwich Islands material fur- 

 nished the specimen which became the type of Deielia 

 fasciaia, Kirbv, an insect w^hich, as McLachlan pointed out 

 (Ann. & Mag. Nat. Hist. (6) x. p. 177, 1892), is nothing 

 else than the heterocliromatic ? of D. phaon, Selys, from 

 Japan, Amoy, and Loo Choo. He added that " the ' Blossom *" 

 visited the latter islands [Loo Choo], and it is not at all 

 improbable that some confusion in the locality labels subse- 

 quently occurred," especially as no " recent investigator of
