" Just the two examples seen and taken." (E. C.) 



This is a species of which we much need specimens. 



Syntaetjctts, gen. nov. 



The species of this genus have hitherto been incorrectly associated 

 with Tarucus (which contains T. theophmstiis and allies) ; it is 

 characterized by hairy eyes, the costal and subcostal of primaries 

 approximated but not fused ; secondaries with a single tail at 

 extremity of first median branch. Type S. telicanus.

Of the last female obtained Mr. Crawshay says : — " A new 

 arrival with the rains, I think"; the female obtained on March 20 

 was taken on the edge of the forest.

I was evidently in error in supposing that this species was a 

 variety of O. cequatorialis, E. M. Sharpe ; it appears to be quite 

 constant and more nearly related to C'.juno, whereas Miss Sharpe's 

 insect (which we received from Euwenzori in the Scott-Elliot 

 collection) is related to C. noquasa. 



The present species nearly resembles G. noquasa on the upper 

 surface, but is usually rather larger ; the males of a richer violet 

 colour with more sharply defined borders, that of the secondaries 

 rather broader : fringes checkered ; occasionally there is a small 

 ocelloid subanal spot on the secondaries ; on the under surface the 

 pattern is much like that of C.juno, but the primaries are longer 

 and the band across the middle of the secondaries is straighter, 

 broader on abdominal margin and tapering to the costa. Expanse 

 of wings 23-27 millimetres. 



I have named this pretty little species after Miss Emily Sharpe, 

 whose careful work on the Butterflies of Africa is well known.
