\\\ 1781 lie identijEied it with Mecistogaster lucretia, Diury, 

 and some colour is lent to this identiHcation by the fact that 

 both species were described from Fotbergill's collection. 

 Drury stated that his lucretia came from the Cape of Good 

 Hope, while Fabricius gave India «s the habitat of his 

 linearis; but, of course, Mecistogaster is exclusively a Neo- 

 tropical geuus. "Whatever may be the identity of the 

 Fabrician type, the species in the Banks Collection is quite 

 distinct from that figured by Drury. The specimen before 

 us was examined by De Selys, and referred by him to the 

 species which he described as M. linearis, F. (Bull. Acad. 

 Belg. (2) X. p. 22, 1860). A note appended to that descrip- 

 tion may be usefully quoted here : — " L'exemplaire de la 

 collection Banks a Londres, qui passe jwur avoir ete etiquete 

 par Fabricius, est un nuile de cette espece, h pterostigma 

 brun (semi-adulte). Les figures de Drury et de Sulzer, 

 citees a l'ai)pui dans V Entomologia systematica, sont au con- 

 traire la lucretia. Quant h. la description de Fabricius, elle 

 peut s'appliquer aux deux esj^ces. Si I'on devait prendre le 

 linearis de Fabricius pour synonyme de lucretia (nom plus 

 ancien), il faudrait adopter pour notre espece linearis le nom 

 de tidlia, de Burmeister." 



II. Specimens in the General Collection of the 

 British Museum. 



In 1793 (Ent. Syst. ii.) Fabricius referred to three 

 dragonfiies in the British Museum Collection. These were 

 Lihellula trimaculata, De Geer ( = L. lydia, Drury), p. 374, 

 no. 3,; L. sinuata { = Falpopleura lucia, Drury), p. 378, 

 no. 17 ; and L. vihrans^ p. 380, no. 30. The first is involved 

 in much obscurity, and the second has not been traced at all, 

 but L. vihrans has been identified with certainty. Unlike 

 the Banksian insects, the two Fabrician specimens now in 

 tlie General Collection carry a plain buff pin-label, with the 

 two upper corners cut off, and bearing the name of the 

 species in Fabricius's handwriting, 



(1) Lihellula lata, F. ? . 

 (= L. lydia ^ Drury, ? .) 



Lolel :— " Lihellula lata Fab.^' 



Apparently this name was never published, and the only 

 reference to it which I can find is one contained in an inter- 

 leaved and annotated copy of Linnseus^s ' Systema Naturae ' 

 (ed. xii.). This book is preserved in the British Museum
