Male. Auteriov wings olivaceous-browu, becoming gradually paler towards apex, and with the 

 following pale spots : — one in cell, a little before lower disco-cellular uervule, two near costa, divided by 

 second subcostal nervule, followed by a curved discal series of six spots placed between the neiTules, 

 a submarginal series of eight spots, of which the upper and innermost one is placed between the thu-d and 

 fourth subcostal nervules, and a marginal series of smaller aud more linear spots. Posterior wings dark 

 oHvacoous-brown, with a large pale discoidal patch situated near costal margin, and indications of two 

 submarginal and a marginal series of pale spots, which are somewhat distinct near apex, but become 

 obsolete towards anal angle. Underside of wings generally as above, but anterior wings with the discal 

 series of spots larger posteriorly, the marginal series to posterior wings more continuous aud distinct 

 towards anal angle, and the posterior margins of anterior wings much paler, especially towards anal angle. 

 Head, thorax and abdomen blackish ; head and anterior portion of thorax spotted with white ; underside 

 of head, sternum and legs black : i^alpi and sternum spotted with white. 



Female. Somewhat larger and paler, with the discal series of spots to the anterior wings more 

 obscm-e, and of the submarginal series those near apes have large pale imier reflections. Posterior wings 

 with a distinct marginal and submarginal series of spots, the last preceded by an inner and more 

 obscure series.

As Mr. Butler has himself admitted the identity of his E. phnhus and E. castelnaui, Feld.,* 

 of which there can be no doubt, it becomes necessary to use the earlier and Felderian name to 

 this insect, though Butler still retains his own designation. + Some uncertainty appears to have 

 arisen as to the exact date of Felder's descriptions of species of Euplwa, Kirby giving 1867 " as 

 the year of pubhcation. Felder's plates bear date 1865, though the text is stated to have 

 been pubhshed from 1864 to 1867, and as Butler himself § gives 1865 as the date of a 

 subsequent description by Felder, it is difficult to see why the apparent law of priority cannot 

 in this case be followed.
