[February, 1881. 
In the French “Annales” for 1870, p. 5, G-uenee described the singular gall- 
making Lepidopterous insect, (Ecocecis Guyonella. This is immediately followed 
(p. 17) by a very interesting account of an Entomological excursion to Celles-les-Bains, 
in Ardeche ; a locality to which attention had already been drawn by the visits 
thither of M. Milliere and of Dr. Staudinger. 
In 1875 there appeared a Catalogue Kaisonne of the Lepidoptera of Eure-et-Loir, 
the Department in which Chateaudun is situated. This was a publication of the 
Societe Archeologique d’Eure-et-Loir, and was probably printed at intervals — the 
title page bears date 1867 ; the introduction is dated “ Mars, 1866,” and the con- 
cluding paragraph bears date “ ler Mai, 1874.” This is, we believe, the last work 
which emanated from Gruende’s pen. It possesses for us a more than common 
interest, for in it we find that two previous notions, which had to us appeared 
strangely unscientific, are quietly ignored. 
In the first volume of the Noctuelites of the Suites a Buft'on, p. 320, we read, 
Triphcena pronuba, Albin ; in the Lepidopteres d’Eure-et-Loir, p. 192, we find the 
more generally used expression, Triphcena pronuba , Liu. Further on, in the same 
volume, we find the uniform -ella termination for Crambina, &c., gently dropped. 
Thus wo find, p. 273, Scirpophaga alba , p. 275, Galleria cereana and Melliphora 
alvearia ; thirty years previously, in the Index Micro-Lepidopterorum, these three 
species had all been forced to bear the termination -ella. 
In the very last paper published by Achille Guenee, “ Etude sur lea Ypono- 
meutides,” in the “Annales” of the French Entomological Society, 1879, p. 281, we 
have an instance of the mellowness of feeling produced by advancing years in the 
very benign mention of the Museum Catalogue of Francis Walker ; he only remarks 
that “ cet ouvrage n’a pas assez de precision,” to allow of the species described being 
quoted without a personal* investigation. 
Entomological Society of London. — December 1st, 1880. Sir J. Lubbock, 
Bart., M.P., &c., President, in the Chair. 
Mr. Pascoe exhibited a scries of Arescus histrio, collected in Ecuador by Mr. 
Buckley, illustrating the extreme and asymmetrical varietal conditions; the Rev. II. 
S. Gorham and Mr. C. O. Waterhouse also alluded to the same subject. 
Mr. Billups exhibited four species of Pezomachus (noticed as Muller i, juvenilis, 
intermedins, and incestus ) new to Britain ; also 20 species of Coleoptera from corn- 
refuse from Mr. Fitch’s granaries at Maldon. 
Sir J. Lubbock exhibited specimens of one of the Phasmidce. sent to him from 
St. Vincent. 
Mr. Cansdale exhibited examples of Tischeria gaunacella, bred by him from 
Primus spinosa. 
Mr. Scott communicated a paper on Hemiplera from Japan. 
Mr. C. O. Waterhouse read a paper on a new species of Poly denes, in which 
he retracted his former opinion as to the affinities of the genus, and acknowledged 
its connection with the Hemiptera. 
* We are by no means certain that this necessity of personally examining “ Walkerian ” types 
has not been a great service to our favourite science. Learned students of various groups of 
insects come from the very ends of the earth to consult the collection of the British Museum, 
and but for this imperative necessity of their so doing, who knows whether some would ever 
have visited Europe at all ? Thus, indirectly, Francis Walker may have conferred a great boon on 
our science.
