Differs from the type chiefly in the greater extension of 

 yellow at the base of the wings and its deeper tint. In the 

 anterior wings of the female this colour extends to the second 

 ante-nodal, to the arculus, and to near the end of the lower 

 basal cell ; and in the posterior wings it forms a triangular 

 basal space reaching the triangle and continued in an oblique 

 manner to the anal margin, some distance below the end of 

 the membranule. 



Male not known. 



Locality. — Auckland and Wellington. 



Tribe COEDULIINA. 



Eesembles LibelliUina, but the eyes have a slight horny 

 tubercle behind, the triangles of the wings are generally wider, 

 the sectors of the arculus are often completely separated, 

 the last ante-nodal nervule is always continuous, there is 

 only a small number of post-nodal nervules, the nodal sector 

 is never undulated beyond the middle, and the males usually 

 have the anal angle of the wings angulated. 



Genus Somatochlora, Selys (1878). 



Tubercles behind the eyes slight. Pterostigma rather 

 short. Fore wings with 7 or 8 ante-nodal and 6 to 8 post- 

 nodal nervules ; hind wings with 5 (or rarely 6) ante-nodals 

 and 8 to 10 post-nodals. Sectors of the arculus united at 

 their bases, but not petiolate. Basal and hypotrigonal areas 

 undivided ; lower basal (or median) area with one cross- 

 nervule in both wings. Internal triangle of the fore wings 

 with three cells ; triangle of the hind wings followed by two 

 cells. Superior anal appendages of the male long, subcylin- 

 drical, ratlaer thicker in the middle ; the inferior pair short, 

 subtriangular. Those of the female long, subcylindrical, 

 slightly curved upwards, and pointed at the apex.
