with 7, and the Cymatophoridge, in which the bar is lost and 

 vein 8 anastomoses with 7. 



(7) The Rhopalocera, which have lost the frenulum, but in 

 some of the lower forms of which traces of vein 1 c and the 

 stalk of the radial vein are retained ; vein 5 of the fore wing 

 is given off either above or below the middle of the disco- 

 cellulars, and vein 8 of the hind wing has become entirely 

 free. In the lowest family — the Hesperiidaa — the subcostals 

 of the fore wing are all given off from the cell, the union of 

 their bases only occurring in the higher families.

XXXV. — On some Small Collections of Odonata (Dragonflies) 

 recently received from the West Indies. By W. F. KiKBY, 

 F.L.S., F.E.S., Assistant in Zoological Department, 

 British Museum. 



The British Museum has recently received some collections 

 of insects of various orders from the West-Indian Explora- 

 tion Committee. Among these were nineteen species of 

 Dragonflies which were collected by Mr. H. H. Smith in 

 St. Vincent and Grenada, an account of which is furnished 

 in the present paper. Four species have been described as 

 new, one of which is regarded as the type of a new genus, 

 while two or three others are new to the collection of the 

 British Museum ; and two specimens, probably new, but 

 belonging to obscure and imperfectly known groups, are left 

 undetermined for the present, the material at hand being- 

 insufficient for their elucidation. 



The whole of the information which accompanied them is 

 here published, being placed between inverted commas. About 

 nineteen species were received, belonging exclusively to the 

 subfamilies Libellulina? and CcenagrioninEe. 



The species described as new are as follows : — 



Brechmorhoga (g. n.) grenadensis. 

 Dythemis multipunctata. 

 Cannacria Smithii. 

 Micrathyria (?) pruinosa. 



All these belong to the Libellulinse.
