of the same. Solely, it would seem, on account of this 

 character the species inconspicuus, Kirby, which in size 

 and colour is utterly unlike a normal Eurys and has also 

 a difference in its neuration, has been placed in this genus. 

 But here, too, a 3 in B.M. has distinctly not 9 joints, but 10. 

 (I have little doubt myself that this species is no Eurys, 

 but a Clarissa, and shall treat it accordingly !). 



Again, Euryopsis, Kirby, is said to have 11 -jointed 

 antennae, and this is true of the only two specimens (both 

 33) on which this supposed " genus " has been founded. 

 But I am almost sure * that these specimens are really 

 the hitherto unidentified 3<$ of two Eurys species of which 

 $$ only have been described. " Euryopsis nitens," 

 \V. F. Kirby. I take to be almost certainly the 3 °f Eurys 

 latins, and " Euryopsis hclla." Rohw.. most probably the 

 $ of Eurys nil id us. The number of joints in Clarissa 

 spp. varies even more. Of divergens, W. F. Kirby, I 

 "have seen specimens with 10. 11, 12, and 13 joints respec- 

 tively, and in the Type (at Oxford) of ('. thoracica, n. sp. 

 the number of joints is 11. Neoeurys, Rohwer, is said by 

 the author to be easily known by its 14-jointed antennae, 

 but in the Type of E. metallica the number of the joints 

 is 15. And in a 3 °f another species from Mount 

 Wellington, Tasmania, it is 11 only ! 



Thus in the comparatively few specimens before me 

 the number of antenna] joints in Eurys (as I should define 

 that genus) varies from 9 to 11, in Clarissa from 9 (or 10 

 it inconspicuus be not included) to 11, and in Neoeurys 

 from 11 to 15. Such a fluctuating character is practically 

 useless for determination of specimens, and even if it 

 were more constant, I should hesitate to consider it of 

 really generic value. 



On other characters, however, the three groups of 

 species, though closely allied, seem capable of being main- 

 tained as at least good subgenera, and perhaps as good 

 genera, though on the existing material I should not 

 myself have ventured to erect them as such. Thus — 



Earns (including Euryopsis) differs from Clarissa in the 

 brilliant metallic coloration of all its species, and also in 

 having the radial cell more distinctly appendiculated, in 

 consequence of which its apex is not adjacent to the 

 margin of the wing. The same character separates it 



* If I am mistaken in tin's, no j\j at all of Eurys have been 

 described !
