2. Philona: " hunne ader 7 nil de spits der aanh<angeel " ; 



Keochera : " hunne ader 7 uit liet midden van deu aciaterrand der aanhaugcel." 

 The position of vein 7 is, neither in the forms referred to Philona nor in the 

 various species of Neochera, constant. In all the insects in question the common 

 stem of veins 8 and 9 comes from the tip of the areole (aanhangcel) ; in inopa (\N'lk.) 

 vein 7 originates usually rather close to this stem, though it is always distinctly 

 separate from it ; sometimes vein 7 is farther removed, and occasionally it stands as 

 far away from the tip of the areole as to originate at the apical third of the free 

 (outer) portion of the areole. On the other hand, in K. eiujenia (Cram.) and allies 

 vein 7 originates generally midway between the apex of the areole and the cell, 

 or is more basal, or stands even close to the anterior angle of the cell ; in many 

 individuals, however, vein 7 approaches the apex of the areole, and has often the 

 .same position as in such specimens of inops (Wlk.) in which that vein has the most 

 basal position. (Jn an average, vein 7 is, however, certainly more apical in inops 

 than in eufjenia, marmorea, etc., and in so far Snellen's statement would be correct, 

 but as that character applies only to the greater number of specimens, not to all 

 individuals, it is neither of generic nor of specific value. 



3. PhiloiKi : " eiudlid der palpen slechts een derde zoo lang als lid 2." 

 Neochera bhaivana, p. 121 : " eindlid der palpen korter dan de helft van lid 2." 



I have measured the joints of the palpi of several specimens, and find that the 

 terminal joint has a length of | mm. in inops, while the second joint is li mm. long ; 

 the latter is therefore only twice, not three times, as long as the third joint. The 

 only structural character of importance by which Walker, I.e., differentiates Pkilo7ia 

 reads : " Third joint of the palpi less than half the length of the second." 



The third palpal joint is shorter in iiwps than in nifirmorea, eugenia, dominia, 

 etc., but this cannot serve to separate ino2JS generically, since N. marinorea and 

 bhawana take an intermediate position and approach more inops than eugenia and 

 dominia. ^Moreover, marinorca and bhawana agree with inops and disagree with 

 eugenia in another character, namely in veins 3 and 4 of the hindwings standing close 

 together, whereas in eugenia and allies they are more or less widely separated (see 

 Snellen, I.e. p. 121). This character again is not constant; there are specimens of 

 eugenia in which those veins have the same position as in certain specimens of inops 

 wliicli are most extreme in respect to the separation of veins 3 and 4. 



W Xeoehera is to be split up into two genera, inops (with privata), marmorea, 

 and MrtWfMirt must come into Philona, and dominia and eugenia (with numerous 

 subspecies) into Neochera, and Philona would be characterised by the somewhat 

 shorter terminal joint of the palpi. However, that character is so slight, and the 

 generic separation of marmorea from eugenia seems to me so unnatural, that I must 

 treat Philona as a synonj'm of Neochera, the more so as inops, marmorea, eugenia, 

 etc., have some remarkable characters in common which distinguish them at a glance 

 from Asota (= Hypsa). 



Snellen, I.e., separated Neochera and Philona from A.'iota by the cell of the 

 hindwing being longer than half the wing, and by the presence of a " viltachtig dick 

 beschubde pleck " near the anterior margin of the hindwing. The first character is 

 quite correct as regards N. marmoi-ea, bhaivana, dominia, and eugenia (inclusive of the 

 subspecies) ; but in N. inops (and jyi-ivata) the cell is mostly just half the length of the 

 wing. In Asola coniorta (Auriv.) (= A. lortuosa Snellen, nee ]\Ioore) the cell to the 

 hindwing is also half as long as the wing [see Snellen, I.e. XXXVIII. p. 180 (1896)] ; 

 va. Aganais ficus (F.) it is likewise of half the length ol the wing. The proportion is
