 This species may be a Debis. I believe that Fabricius occasion- 

 ally uses the locality "in Indiis" instead of "in India."

This species appears to me to be allied to Lasiommata dejanira 



(Europe) ; it bears a strong resemblance to Debis portlandia (United 



states). 



Linnaeus, in his ' Systema Naturae ' (1766), briefly characterizes 



this species, and refers for a fuller description of it to the « Amceni- 



tates Academical published in 1749. Fabricius refers to P ar- 



yanthe (sic), Cramer, i. pi. 17. t. 204. f. C, D, as his species. This 



g £u e ' k° wever > does not at a11 a g ree wi th his description. 



I he following species does not belong to the genus Euptychia, 

 but is identical with Chionobas bore, Ochsenheini. See Fabricius's 

 type in the Banksian Collection :—
