20 L. de Niceville — Butterflies of the subgenus Tronga. [No. 1, 



an exception to my theory that two allied species of the same subgenus 

 do not as a rule occur in the same region. The synonymy of the 

 subgenus has been greatly changed since Dr. Moore's Monograph of the 

 Euploeina was published in 1883, and since his " Lepidoptera Indica " 

 appeai'ed. In the first-named paper his No. 1, alcatJioe, Godart, is the 

 douhledayi of Felder; his No. 3, menetriesii^ Felder, is the gardineri of 

 Fruhstorfer; and his No. 4, pinwilUi^ Butler, is the menetriesii of Felder. 

 I think the number of recorded species in this genus will be greatly 

 reduced in the future, and many of the names given above as repre- 

 senting distinct species will be reduced to the rank of synonyms. I 

 possess only douhledayi, deione, gardineri, limhorgii, menetriesii, alcathoe,
