[21. Leptocnemis { = Hemicnemis) cyanops (Selys). 



Trichocnemis cyanops Selys, Ann. and Mag. Nat. Hist. (4), iii. p. 275 (1869). 



This species was described by Baron E. de Selys-Longchamps from a male, or males, 

 taken in the Seychelles by Prof. E. Pei'ceval Wright, but it does not appear to have been 

 re-discovered by later investigators. 



Through the courtesy of Mr H. M'Lachlan, I have had an opportunity of examining 

 the type $, the sole representative of the species, contained in the late Mr R. M'Lachlan's 

 collection. Upon comparing it with the type of L. bilineata, preserved in the same 

 collection, and also with specimens taken by the Expeditions of 1905 and 1908 — 9, 

 I failed to discover in it any distinctive characters such as would enable me to refer 

 other specimens to the same species with any degree of certainty. 



M. Rene Martin says of this insect : — " Speciale aux Sechelles, ou elle doit etre 

 rare. Peut-etre H. cyanops n'est-il pas une espece differente de H. bilineata. On trouve 

 des individus du bilineata qui ont, melanges, les caracteres assignds par M. de Selys a 

 chacune des especes" (Mem. Soc. Zool. France, ix. p. 109 (1896)).]

I have seen this pretty brick-red Dragonfly from Madagascar, Sokotra, and from 

 numerous localities in Continental Africa.

Widely distributed in the tropical parts of Africa and Asia, and recorded also from

Loc. Seychelles. Mahd : I ^, 1 ?, marshes on coastal plain at Anse aux Pins and 

 Anse Royale, I. 1909. Silhouette : 14 ^, 15 ?, Pointe Etienne, low cultivated country, IX. 

 1908 ; 1 $, Mare aux Cochons, IX. 1908. Praslin, 1905. Coetivy, 1905. 



Dr Ris, who has specially studied the genus, has been good enough to examine the 

 whole of the Agriocnemis material brought from the Seychelles by the Expeditions of 1905 

 and 1908 — 9. He finds that A. exilis, the species to which Mr Laidlaw referred the 

 specimens obtained in 1905, is not represented at all. The males are rather large, but
