220 SPOLIA ZEYLANICA. 
‘«¢ Journal of the Bombay Natural History Society” ; to avoid the 
necessity of reference, it may be mentioned that the pupa of helenus 
resembles that of polytes, but is slightly larger, and is bent back 
at an angle of almost 90 per cent. Demoleus differs from polytes 
in being comparatively narrow across the hind part of the thorax ; 
polytes is very wide in this region, and as a rule is bent back 
at a greater angle than demoleus. Parinda is, of course, easily 
recognized by its superior size, as compared with any of the 
other species. 
Tn conclusion it should be noted that the above distinctions apply 
in Ceylon only ; in India, where other orange-feeding Papilios occur, 
considerable modification would probably be necessary. 
My thanks are due to Mr. E. EK. Green, who has most kindly figured 
the full-fed larva of each species. To avoid confusion, only the 
salient characteristics of each are represented, small unimportant 
markings being neglected.

34. ‘ Filodes mirificalis,” a good species.—This pyrale was first 
described by Lederer in 1863 under the name Auxomitia mirificahs 
(Led., Wien. Ent. Mon., 1868, p. 391); subsequently it was re- 
described by Moore* as Filodes patruelis (Moore, Lep. Atk., p. 218), 
but in the ‘‘ Fauna of British India’? (Moths, Vol. IV., p. 297) 
it is reduced to the status of a variety of Filodes fulvidorsalis, Hubn. 
Mr. E. E. Green has always expressed the opinion that the two forms 
should rank as good species, and this view has now proved to be 
correct. Both species have been bred at Peradeniya, marked 
differences being found in the larve, while in every case the imagoes 
proved true to the maternal type. For a general description of F. 
fulvidorsalis the ‘‘ Fauna of British India ’’ must be consulted ; the 
following table presents the essential differences between the two 
species :—
