Cceliccia octogesima (Selys). 



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

 1 2 • Matang Ed., 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 species are evidently 

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

 to redetermine Selys' species.

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 photograph 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.
