the hind wing becoming widely separated from the cell except 
near the base; (2) the Larentiine, by the bar migrating to 
near the end of the cell, or by vein 8 anastomosing with the 
cell to near its end; (8) the Boarmine, by vein 5 of the hind 
wing becoming aborted, vein 8 being free or retaining the 
bar in the lowest forms, such as Abrazxas and its allies. 
In the original scheme of the work it was estimated that 
it would be possible to include most of the subfamilies of 
the Pyralide within the limits of the third volume, but the 
great activity that has prevailed among students of Indian 
Moths and the large number of species that have been 
described during the four years that the volumes have been 
in preparation have made this impossible. The publication, 
however, of M. Ragonot’s first volume on the Phycitine, a 
eroup of Moths that, owing to the ravages committed by 
many of the species among forest-trees, corn, cotton, tobacco, 
&c., is of more economic importance than any other, except 
perhaps the silk-producing Bombycide and Saturniide, and 
the approaching completion of his second volume, which 
will include the Gallertine, have made it possible to study 
the subject as a whole. Thus the postponement of the 
Pyralide is hardly to be regretted if at some future time 
a fourth volume is sanctioned containing the whole of 
that family and also an Appendix bringing the rest of the 
work up to date. This would complete the subject down 
to the fareilies for which Lord Walsingham has the whole 
of the material in course of preparation for publication. 
I have to thank Dr. O. Staudinger for his courtesy in 
sending me the types of all the species described by Mr. Moore 
from the Atkinson Collection, of which no specimens exist in 
England, and for having thus enabled me to determine the 
affinities of many species I had otherwise no means of classi- 
fying. The whole of the gentlemen mentioned in the preface 
to my first volume have also continued their assistance in 
the freest and most generous manner. In addition Mr. G. 
C. Dudgeon has first placed at my disposal, and then presented 
to the British Museum, the results of his many years’ col- 
lecting in Sikhim and Bhutan; and, lastly, M. L. de Nicéville, 
the author of the invaluable volumes on the Butterflies of 
India, has sent me many new and rare species from Tenasserim.
