aberrational specimen in the whole of my long series. Some 
(usually males) are somewhat darker beneath, others (usually 
females) have a small spot placed just above the ordinary 
double white -pupilled apical spot, but in no specimen are 
the two characters combined. " The Tyrolean specimens are 
considered by Staudinger, Elwes, and Lang to be ' varieties,' 
that is, local races. My series shows that the Tyrolean 
specimens have an exceedingly wide range of aberrational 
variation which might with advantage be worked out, but 
that so far as developing special races in the Tyrol is con- 
cerned, the specimens from Mendel and Cortina exhibit not 
only a range of variation including the type and the 
described forms, but a range extending in its extremes far 
beyond the limits of these, as laid down by the authori- 
ties." 
Mr. Elwes, in reply, said that at the time he wrote on 
Erebia he had not personally collected E. nerine, but that 
having specimens from Bozen sent him as a " var. morula^'" 
which, as compared with others from the Italian Alps near 
Bormio, were " minor obscurior, subtus unicolor," he con- 
sidered himself justified in treating them as a variety, defined 
by Staudinger. Since then he had taken many of E. nerine 
in the district north of the Lago di Garda, and found, as Mr. 
Tutt had done, great variation among them. But without 
knowing more of the extent of this variation in other locali- 
ties, he did not think either Mr. Tutt or himself would be 
justified in stating that there were no local forms worthy of 
definition, though without question many of the named 
varieties in Staudinger's catalogue were now proved to be 
fairly separable when a sufficient number from different 
localities were brought together. As to Lang's work, he had 
never paid any attention to it, as he had always considered 
it a mere compilation. 
Lord Walsingham exhibited the type and paratypes of Pseudo- 
doxia limulus (RgMr., Drnt.), together with the larval cases 
and a preserved larva. His Lordship directed attention to 
the curious truncate concave head of the larva which forms 
an operculum to the tube, and remarked that the cases of this 
insect, which were apparently not uncommon in Ceylon, the
