Manipur and the Borders of Assam, 337 



that he potted a number of plants, and after looking over 

 them, or, in his own words, " carefully examining every leaf 

 for eggs or larva3," he placed upon them females of Terias 

 mandarina^ and the result was that he bred T. mandarina 

 (at which he was greatly astonished, and immediately decided 

 that this was a seasonal form of another species) ; he also bred 

 T. Mariesii and some of the intergrades, which seem not to 

 have astonished him at all. 



Mr. Fryer's experiments may be satisfactory, or they may 

 not j if the plants possessed a great number of leaves, the 

 probability is that some eggs were overlooked ; if they were 

 roughly potted, it is not improbable that such eggs as were 

 upon them fell upon the mould and were hatched there ; but 

 anyhow T. mandarina cannot be called a seasonal form of 

 T, Mariesii or T. hecahe, if it produces itself. 



Secondly, Mr. Distant expects that breeding will prove T. sari 

 to be " only a variety of T. hecahe ; " if so, why not expect the 

 whole of the Old-World species to prove varieties of T. hecahe, 

 since forms closer to T. hecabe than T. sari are found in all 

 parts of Asia, Africa, and Australia ? Is it reasonable to sug- 

 gest that T. sari^ a purely Malayan species, may be a variety 

 of a species which ranges from Darjiling to the Philippines, 

 or, at any rate, is at present assumed to do so (for it is doubt- 

 ful whether all the specimens now referred to T. hecabe are 

 rightly placed with that species). Mr. Distant remarks that 

 breeding experiments have not yet proved that T. sari is a 

 variety of T. hecahe ; yet Horsfield, Thwaites, and Mackwood 

 have all bred it, by his own showing. However I am will- 

 ing to accept his admission — a rash one for an entomologist 

 to make — ''I treat this species as a variety" (see p. 321). 

 I know of many lepidopterists who do this ; but Mr. Distant 

 is the first who has boldly come forward and confessed it.

A pair of a Terias agreeing best with this species, but 

 apparently distinct; I, however, consider that, as the diffe- 

 rences are slight, two somewhat imperfect specimens are 

 insufficient material upon which to separate this form from 

 T. venata.
