•14G Ml". H. Campion 0)t Fulriciua^a Types of 



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

 type clearly belongs to the Asiatic form CrocotJiemis servilia, 

 Dnuv, 1773. This is shown by the abdomen, which is 

 parallcl-sideJ and devoid of mid-dor.sal 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. 

 Tliere are 11| antenodals in each fore wing. Diury's figure 

 of Libellula servilia, from China (III. Ex. Ent. i. pi. xlvii. 

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

 natn^ the main points of difference being that the abdomen is 

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

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

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

 as synonyms of his L.ferruginea. In the original descrip- 

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

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

Label : — " Libellula 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 disa[)peared. Is'evertheless, the character of the basal 

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

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

 Chinese species now known as Tramea Virginia, Ramb. 

 Tiiis Chinese species is usually referred to as Tramea chi- 

 nensis, De Geer, but, as a case of homonymy is involved, 

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

 recently 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 

 liabitat as " Amerique septentrionale " (Ins. Nevr. p. 34; 

 1842).

In this passage, which is quoted in extenso, Fabricius 



proposes 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
