rossi, Cust. (=ero, Brem.) Melitea iduna, Dalm. and Arctia 
thulea, Dalm. were the most remarkable. Of the latter insect 
he believed two specimens only had been previously taken, 
the type in Lapland and a second in Eastern Siberia. He 
described the character of the country and the climate, which 
is a very peculiar one; dry and hot during the extremely 
short summer, but subject at elevations above 6,000 feet, 
where most of his time was spent, to thunder- and snowstorms 
almost daily. The total number of butterflies now recorded 
from the region stood at about 180, a larger number than had 
ever been taken in a similar area in Northern Asia, as far as 
he knew. The Heterocera of course represented but a very 
small part of what would be found in the Altai by a collector 
who could give up his whole time to it, but as the time during 
which he had been able to collect was little more than a month, 
during which he had ridden nearly 1,000 miles, and the nights 
when clear were almost always frosty above 7,000 feet, he had 
been able to do no night work. There were very few novelties 
in the collection, but when thoroughly worked out, which he 
hoped to do in time for publication in an early part of next 
year’s Transactions, he thought the list would be a valuable 
contribution to our scanty knowledge of the Lepidoptera of 
Siberia. He concluded by saying that now that the Siberian 
railway made the journey as far as Irkutsk a comparatively 
short and easy one, he hoped other English naturalists would 
visit this very interesting country, especially as every facility 
was given by the Russian government to bona fide scientific 
travellers provided with proper credentials. 
Mr. Bareson congratulated Mr. Elwes on the great success 
of his expedition. The collection was full of interesting 
features. The presence of so many forms recalling N. American 
and Arctic faunas was clearly a point of great importance. In 
this connexion he called attention to a specimen of P. napi ?, 
having the brown veining on the upper side almost as much 
marked as in the var. bryonie of the European Alps. The 
ground colour was nevertheless white, instead of yellow as it 
is in bryonie. He had lately received a specimen taken by 
Mr. Gayner at Lulea in the N. of Sweden, which was practically 
identical with that brought by Mr. Elwes from the Altai.
