CCELICCIA OCTOGESIMA (Sel3^s). 



G. octogesima Kirby, Cat. Odonata, p. 128 (1890), 



1 $. Matang Rd., 3.i. 10. 



This specimen, unfortunately much damaged, agrees well with 

 the description of the type female in the Synopsis. 



It differs from other females of the genus I have seen in the 

 greater length of the spine developed on the posterior margin of 

 the prothorax, which projects forward at an angle of about 45° to 

 the main axis of the body and is approximately 1 mm. in length. 



I have not been able to identify any of the species I have seen 

 with C. borneensis Selys, and as the Bornean sj^ecies are evidently 

 numerous, and often very similar in apjDearance, it will be difficult 

 to redetermine Selys" species. 



Legion Agrion.

I take the opportunity of figuring here the venation of the 

 type male of this interesting species (text-fig. 10). It shows a 

 development which parallels with remarkable exactitude that 

 of Cceliccia. I am indebted for the photogi-aph of the wings of 

 this species, and of all the new species of Cceliccia described in 

 this note, to Messrs. H. and F. E. Campion, to whom I desire to 

 tender my best thanks.

Teinobasis surERBA (Selys).

 Nova Guinea, xiii. Zool. pp. 100, 101, 122 (1915).

 The specimen belongs, I think, to the typical race of this species.
