On some Type-specimens of Lepidoptera and Coleoptera 
in the Edinburgh Museum of Science and Art. By 
Percy Hall Grimshaw, F.E.S. 
{Abstract.) 
(Read May 17, 1897.) 
The paper dealt with fifty-two species of butterflies and nineteen 
of beetles, the type-specimens of which had been discovered by the 
author in a collection purchased by the University of Edinburgh 
from M. Duf resne of Paris in the year 1819, and afterwards trans- 
ferred to the Museum of Science and Art. In the case of the 
butterflies, the species referred to were described by Godart in the 
Encyclopedie Methodique , while the beetles belonged to species 
described by Olivier in the same work, and also in his Histoire 
Naturelle des Insedes — Coleopteres, published about the same time. 
By the comparison of these original specimens with others in the 
Natural History Collections at the British Museum the author has 
been enabled to clear up many points in synonymy, etc., which 
have for nearly eighty years remained doubtful and obscure. The 
most important results of the investigations may be summarised as 
follows : — One of the beetles has been found by Mr Gahan, of the 
British Museum, to be the type of a new genus, which is charac- 
terised in the present paper, while the specimen upon which it is 
founded is probably unique; it has been found necessary to re- 
name one species of butterfly and one beetle ; errors in synonymy 
have been corrected in the case of nineteen species; and eight 
species hitherto wrongly placed have been referred to their proper 
genera. 
Coloured drawings have been prepared by the author of the 
most important of these type-specimens, and they will be repro- 
duced in a plate accompanying the paper, which will be printed in
