to some uneatable genus or species, and this may apply in the present case. Dr. Horsfield, 

 who was no advocate of this theory, writing in pre-Darwiuian times, and with a strong leaning 

 to the views (Circular and Qninariau) of MacLeay, with the thoroughness that marks all his 

 work, was struck by the appearance of these larvae, and sought for their analogy.* This he 

 considered was to he found in the Myriopoda and in the genus Srtititjcra. On the lines of this 

 theory (mimicry) such a view is extremely interesting, and acquires a reasonableness which 

 the MacLeayiau doctrine f failed to supply.

^rale and Female. Wiugs above fuliginous-browu ; cell of anterior wings crossed by two waved 

 blackish lines at centre (between wbicb is a prominent carmine spot), and two lines converging posteriorly 

 at extremity ; cell of posterior wings witb a faint blackisb oblicpie line near centre and two prominent 

 black lines at apex ; botb wings crossed by a discal curved fuliginous fascia, commencing on anterior 

 wings near end of cell, wbere it is bi-oadest, and terminating ou posterior wings near centre of abdominal 

 margin, wbere it is narrowest; beyond the fascia the colour is slightly paler, the posterior wings 

 possessing a somewhat faintly darker and very narrow submarginal fascia. Wiugs beneath pale greenish ; 

 cellular markings of anterior wings as above, but witb the interspaces between the pairs of lines pale 

 brownish; a sub-basal fuscous streak outwardly margined witb white, and an irregular spot beneath 

 cell near base of third median nervule ; cellular markings of posterior wings as above, but witb an 

 additional curved black line beyond apex, a similar but shorter mark near and between the bases of 

 the discoidal and lower subcostal nervules, — this is preceded by a rounded spot between the subcostal 

 nervulos and a larger and partly closed one containing a carmine spot between the upper subcostal nervule 

 and costal nervure ; there is also a small carmine spot in cell ; a darker discal fascia crossing both wings 

 as above, a similarly coloured broad submarginal fascia commencing on anterior wings at upper discoidal 

 nervule and becoming obsolete on posterior wings at the median nervules, followed by a waved and 

 lunulate fascia broken between the nervules ; the anterior wings also possess a broad, darker oblii^ue 

 subapical patch, its margins and also the apical margin of posterior wings more or less infuscated.

A single male specimen collected by Dr. Townsend in Perak, and which is here 

 figured, is the only knowledge I have of the species in this fauna. It is in itself closely 

 allied to A. evelina, StoU, and has been called a local race of that species, simply, and 

 necessarily, because Stoll's species was tirst described. Philosophically, however, as A. derma 

 has an exceedingly wide range, it is probably the archaic form, and A. evelina the more or less 

 local race.
