Description from Seitz

N. themis Leech (54f) differs from the preceding species in the median band on the hindwing beneath being anteriorly abbreviated and in the 2—3 violet spots standing in the prolongation of the band being absent; on the other hand, there is on the forewing below a large light spot near the distal margin between the radials.*) The distribution-area of this form according to Oberthur extends from West China (Siaolou) to Sikkim, where it is replaced by the nomenclatorially typical form, ''N. nycteus'' Nicev., which has white instead of yellow spots. *Contrary to customary treatment ''N. themis'' and ''thisbe'' are here dealt with as different species. In this I follow Ch. Oberthur's opinion (''Etudes de Lepidopterol.'' Comparee II), although the differences do not appear to be quite sufficient for specific separation. There can hardly be any doubt that the classification of the species of ''Neptis'', especially of the ''thetis'' group, will be modified in many respects as our knowledge of the geographical distribution and seasonal variation increases. At present one has to be content with a grouping which is the more probably correct classification according to one's personal opinion. As not weighty enough I must regard the characters of a number of species described by Oberthur in the place cited; particularly the separation of ''thisbe'' from ''themis'' and the specific value attributed to some forms of the ''thestias'' series does not seem to be tenable. — Stichel.
