London, were also known as at one time collectors of British 
Lepidoptera, but Iam not aware that either has written any- 
thing of permanent interest. ' 
Among foreign entomologists who have died in 1894, I find 
but very few names of note. The most eminent perhaps were 
Lucien Francois Leruterry, who died at Lille on April 4th, 
aged 64. Together with Dr. A. Puron, he probably held the 
first place among Hemipterists, and had commenced to pub- 
lish a general Catalogue of the Hemiptera of the world, 
of which the first part appeared in 1893. He had been a 
member of the Entomological Society of France since 1857. 
Dr. Jacop Spinepera was a well-known Swedish entomo- 
logist, who had written on Hemiptera, and published a mono- 
graph of the Scandinavian Psocida, and some papers on 
Lepidoptera as well. He was a leading member of the Swedish 
Entomological Nociety. 
Hueco Tueopor Currstopn died at St. Petersburg on 
Oct. 24, aged 63. He was one of the most energetic collec- 
tors of insects in Europe, and had travelled extensively for 
many years in various parts of the Russian Empire, especially 
in Amurland, North Persia, Transcaspia, and the Caucasus. . 
A Saxon by birth, he went to Sarepta as a teacher in 1858, 
and at once began to make his name well known among 
Kuropean lepidopterists. Of late years he had been employed 
by the Grand Duke Nikolas Mikhailovitch as curator of his 
collections, and had resided at St. Petersburg, except during 
the summer months, which he usually spent in the Caucasus. 
He had written numerous papers on the results of his expedi- 
tions, and described many new species of Lepidoptera. He 
will be a great loss to science, as there was probably no one 
better acquainted with the Lepidoptera of the Russian Empire. 
The subject which I have chosen for my address is one 
in which for many years I have taken great interest, 
namely, the Geographical Distribution of Butterflies; for 
though a great deal has been written of late years on 
the distribution of plants, mammals, birds, fishes, and 
reptiles, comparatively little has yet been done, so far as I 
know, by entomologists to show how far the natural divisions
