and spots at the base and sides, followed by a double row of 

 linear markings on segments 2 to 7, that on segment 6 

 smallest and that on segment 7 largest; legs black, front 

 trochanters and femora yellow beneath ; anal appendages 

 black, as long as the eighth segment, the lower appendage 

 yellow, except at the sides, above and below, and nearly as 

 long as the others. Wings hyaline, slightly tinged with 

 yellow at the base, but sometimes yellowish or smoky hyaline, 

 with even the tips clouded; pterostigma brown, sometimes 

 yellowish in the centre ; fore wings with 12 or 13 antenodal 

 and 7 to 9 postnodal nervures ; post-triangular space with 3 

 cells increasing, subtriangular space consisting of three cells ; 

 hind wings with 9 or 10 antenodal and 7 to 10 postnodal 

 nervures.

" Great Head Swamp, southern end of island, near sea, 

 Dec. 24." 



" Pools near Bannonallie, Jan. 12." 



"Richmond (Leeward), near sea-level, Dec. 14. This 

 species is rather rare about open streams." 



"Hermitage Estate, Cumberland Valley, 1000 feet, Jan. 20. 

 Open land, rare." 



10. Dythemis multipunctaia, var. (?). 



These specimens are clouded hyaline, with dusky tips, and 

 the antenodal and postnodal cross-nervures are rather closer 

 together ; but I cannot find sufficient characters to separate 

 them specifically at present.

11. Cannacria Smithii, sp. n. 



Long. corp. 42-44 millim. ; exp. al. 70-80 millim. ; long, 

 pter. 3-4 millim. 



Differs from Cannacria Batesii, Kirb., the type of the 

 genus, in having only 9 antenodal and 8 postnodal nervures 

 on the fore wings, and 6 antenodal and 8 postnodal nervures 

 on the hind wings, and the abdomen is somewhat shorter and 

 broader ; but in every other respect this species exhibits all 

 the characters of my genus Cannacria. 



Rufo-testaceous, frontal tubercle darker, shining, and bifid 

 in front ; abdomen with a more or less distinct dark band 

 above, commencing on the fourth segment, and contracted into 

 an hour-glass-shape between each two incisions; sometimes 

 it is brown and hardly visible, at other times it is blackish, 

 but is always darkest towards the extremity of the abdomen.
