446 Mr. H. Cauipiou on Fubricius^s Types of 



locality, however, is manifestly a wrong one, as Fabvicius's 

 type clearly belongs to the Asiatic form Crocothemis servilia, 

 Drury, 1773. This is shown by tlie abdomen, which is 

 parallel-sided and devoid of mid-dorsal black spots, and by 

 the wings, which are narrow and rather smoky at the tips. 

 The abdomen measures 27*5 mm. and the hind wing 34 mm. 

 There are 11^ antenodals in each fore wing. Drury's figure 

 of Lihellula servilia, from China (111. Ex. Ent. i. pi. xlvii. 

 fig. 6; 1770), agrees fairly well with the type of L. ferriigi- 

 nata, the main points of difference being that the abdomen is 

 too long and that the coloured area at the base of the fore 

 wings is too large. In 1793 (Ent. Syst. ii. p. 380) Fa- 

 bricius treated his L. ferruginata, as well as L. servilia, Drury, 

 as synonyms of Ins L.ferricfjinea. In the original descrip- 

 tion of L. ferrughiea, 1775, the habitat was given as 

 " America," but in 1793 the habitat was changed to " China." 



(8) Lihellula Carolina, Linn. ^ . 

 (^ = Tramea Virginia, Ramb.) 



Label : — " Lihellula Carolina Linn. S. N. p. 504. n. 17." 

 The base of the abdomen is in poor condition, the contents 

 having apparently been eaten out by mites, and the hamules 

 have disappeared. l!«Jevertheless, the character of the basal 

 spot in the hind wing is sufficient to show that the insect is 

 not the North-American Traniea Carolina, Linn., but the 

 Chinese species now known as Tramea Virginia, Ramb. 

 This Chinese species is usually referred to as Tramea clii- 

 nensis, De Geer, but, as a case of homon3'my is involved, 

 Dr. Ris (Cull. Selys, Libell. fasc. xvi. (1) p. 978 j 1913) has 

 recesitly restored to it Rambur^s name of Virginia. Re- 

 examination of Rambur's type has revealed its Asiatic 

 origin, notwithstanding that author's erroneous citation of its 

 habitat as " Am^rique septentrionale " (Ins. Nevr. p. 34 j 

 1842). 



(9) ^shna grandis, Ij'uu). c? . 

 { = ^schna cyanea, Miill.) 



Label'— '' M&\m^ Grandis Fabr. Sp. Ins. No. 2." 

 Keference: — "A. thorace lineis quatuor flavis, corpora 



variegato. Habitat et in Insulis kSandwichii Mus. Dom. 



Banks.''— F., Mant. Lis. i. p. 339, no. 2 (1787). 



In this passage, which is quoted in extenso, Fabricius 



])roposes to extend the distribution of ^.grandis, as given 



in his earlier writings, so as to include the Sandwich Islands. 



The locality is not repeated in Fabricius's list of 1793, and
