Madeira (WbUasfon, several examples; Eaton, 1 very adult?, 

 23rd December) . 



Canaries ( Welb et Berthelot ; but there is a possibility that the 

 next species was intended by Brulle). 



Although I use the name striolatnm, it is now, I think, gene- 

 rally believed that the species so termed and the vulgata of 

 Linne are not separable.

Canaries : near Las Palmas, Grrand Canary, 6th December

A widely distributed species, which (notwithstanding its occa-

 the temporary possession of materials communicated by Baron de 

 Selys. I have also been able to examine the (now mutilated) $ 

 type of Olympia, Brulle, which is certainly distinct from Boyer de 

 Ponscolombe's Erench insect {=cariilescens. Fab.) of that name. 

 Not only specific, but also generic perplexity has been the result. 



It has been considered probable that clirysosilgma, Burm., 

 might be identical with trinacria, Selys, which, if well founded, 

 would necessitate the deposition of the latter name as a synonym. 

 Lihellula trinacria has been referred to the genus Lepthemis, 

 Hagen, which is especially characterized by the much iuflated 

 base of the abdomen in loth sexes. The type of Lepthemis is the
