From the above table it will be seen that Leptosomus gracilis has in general a shorter wing than 
L. discolor, and it would also appear that whereas in L. discolor the female is generally larger than 
the male, in L. gracilis she is somewhat smaller than the male. 
I have not thought it necessary to figure the male of this species, but have figured the 
female only. 
The specimens figured and described are in my own collection, with the exception of the 
young male, which is in the British Museum. 
In the preparation of the above article I have, besides the series in the British Museum, 
which embraces those in the Shelley Collection, examined the following specimens:— 
E Mus. H. E. Eresser. 
a. c( ad.; 6, S ad. Grand Comoro, 1878 [Sir J. Kirk). 
E Mus. A, & E. Newton. 
a, ^ ad .; b, ? ad. Grand Comoro.
