346 GROTE—GORTYNA AND ALLIED GENERA. [May 4, 
A list of the donations to the Library was presented and 
thanks were ordered therefor. 
The decease was announced of the Duke of Argyll at 
London, on April 24, aged 77 years. 
Mr. A. Radcliffe Grote presented a paper entitled ‘‘ His- 
torical Sketches of Gortyna and Allied Genera.”’ 
Dr. Sellers called attention to the Hawkins polygraph, 
formerly the property of and much used by Thomas Jefter- 
son, an ex-President of this Society, and exhibited several 
letters from Jefferson to the late Charles Willson Peale, 
devoted to the subject of the polygraph, which he had 
obtained from Peale. 
The Society was adjourned by the presiding officer.

GENERA.

The exact determinations of certain North American species of 
Gortyna by Mr. Henry Bird, of Rye, N. Y., which largely rendered 
the recent revision possible, as well as the discovery of the larval 
stage of several species by this excellent lepidopterist, make it 
again a matter of importance to present a sketch of the use of gene- 
ric titles for the species in literature. While as to the type and 
use of Gortyna I do but sustain my former position, I again cor- 
rect here my earlier statement that this generic title was originally 
published by Hubner. I cannot find it in the Tentamen and I 
have clearly made a mistake in so crediting it in 1876. Iam here

Micacea thus becomes the type, as always stated by me, but only 
and sufficiently through this restriction. The genus should, there-
