Odonata from Neio Caledonia. 57 



loop containing eight cells, and the secondary (proximal) 

 loop from four to six cells. 



Legs dark reddish brown ; coxse and tibial keels pale 

 brown. 



Abdomen a little constricted at segment 3 and between 

 segments 8 and 9. Dorsum of segment 1 and basal third of 

 segment 2, auricles, and lateral and ventral aspects of all 

 the segments dark reddish brown. Dorsum of the distal 

 two-thirds of segment 2 and segments 3-10 black, with 

 yellow markings on 2-8 as follows : — On 2 a pair of trans- 

 verse lines followed immediately by a pair of subquadrate 

 spots, both pairs interrupted mid-dorsally ; on 3 and 4 a 

 pair of basal spots, forming more or less part of a ring, and 

 a pair of central spots somewhat rounded and almost 

 touching one another mid-dorsally ; on 5, 6, and 7 a pair of 

 rounded spots, similar to those on 3 and 4, but placed rather 

 more proximally and separated more decidedly by the mid- 

 dorsal carina ; on 8 a pair of large elongated spots. 



Upper anal appendages (fig. 9) about 4 mm. long ; in 

 dorsal view wavy, dilated internally before the middle, then 

 emarginate, and dilated again just before the apex, which 

 is rather obtuse; fuscous as far as the central dilatation, 

 whitish beyond, the apex edged with fuscous : in lateral 

 view curving gently downwards and then upwards again, 

 stout, rather slender at base. Lower appendage about two- 

 thirds as long as the upper appendages, curving gently 

 upwards, triangular in dorsal view, very dark reddish brown, 



I have the honour of dedicating this very fine species to 

 the memory of its discoverer, who afterwards gave his life 

 in the cause of freedom on the battlefields of Macedonia. 

 It is immediately recognised from all other Synthemini by 

 the absence from the meso-metathorax of any pale spots 

 or stripes.
