Dr. Watt obtained fifteen examples, the largest of which 

 measures 64 millim. in expanse of wing, and thus compares 

 favourably with G. aurorina of Europe. The smallest example 

 in the Museum- series is one from the N.W. Provinces of 

 . India ; it not only differs in its greatly reduced size and some- 

 what more produced primaries, but in its narrower borders, 

 blackened veins, and pupilled discocellular spot ; possibly it 

 may be distinct ; its expanse of wing is only 36 millim. I 

 leave the question of the distinctness of these two forms 

 mitil further material turns up ; perhaps Mr. Elwes will be able 

 to decide the matter. 



Before passing on to the next genus ( Terias) I feel called 

 upon to say somewhat touching Mr. Distant's recent treat- 

 ment of the genus (Lep. Malayana, pp. 302-307), which is 

 based wholly upon the supposition that Mr. Fryer's experi- 

 ments with Japanese species were as careful as he himself 

 thought them. From long experience in plant-growing I 

 know well that nothing is easier than to overlook such con- 

 spicuous objects as scale-insects, even though one fancies 

 one has examined carefully every leaf of a plant j how 

 much more so the small eggs of Teri'asl Mr. Fryer says
