On Cretaceous Fishes from Mount Lebanon. 405 



The female approaches that sex of T. dispar, Grose-Smith, 

 but the white bands on both wings are very much broader. 

 It is a smaller insect than any of the above-mentioned species. 



Thysonotis suleima. 



Male — Upperside more greenish blue than T. zuleika ; an- 

 terior wings with the costal margin at the base and the outer 

 margin more broadly black, and the central white band is not 

 irrorated by blue scales. 



On the underside of the anterior wings the blue band 

 which traverses the outer marginal black area is narrower 

 along the outer margin than in T. zuleika • on the posterior 

 wings the inner edge of the submarginal blue band is lunulate 

 between the veins, and the black spots in it are larger than in 

 T. zuleika. 



Female. — Upperside closely resembles the same sex of 

 T. zuleika, but on the anterior wings the apical area is not 

 tipped with white, and the white band which crosses the 

 middle is more oblique. 



On the underside the apex of the anterior wings is not 

 tipped with white, and on the posterior wings the submarginal 

 blue band is also lunulate on its inner edge, the spots in this 

 band being likewise larger. Cilia rather broadly white, 

 crossed by grey at the ends of the veins. 



Expanse of wings If inch. 



/lab. St. Aignan Tsland (Meek). 



In the collections of Mr. Grose-Smith (types, $ ? ) and 

 the Hon. Walter Rothschild. 



This species is closely allied to T. zuleika, but the different 

 colouring of the male, the absence of the white tips on 

 the anterior wings of the female, and other distinctions are 

 sufficient to separate them.

The descriptions and figures given in the memoir on the 

 Cretaceous fishes of Mount Lebanon by the late Mr. James W. 

 Davis * are scarcely adequate for the purposes of ichthyology. 

 To understand this important extinct fish-fauna it is necessary
