In the French "Annales" for 1870, p. 5, Ghienee 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 Eaisonne of the Lepidoptera of Eure-et-Loir, 

 the Department in which Clmteaudun 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 Gruenee'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 Buffon, p. 320, we read, 

 Triphana pronuba, Albin ; in the Lepidopteres d'Eure-et-Loir, p. 192, we find the 

 more generally used expression, Tripkcena pronuba, Lin. Further on, in the same 

 volume, we find the uniform -ella termination for Crambina, &c, gently dropped. 

 Thus we 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 Gruenee, " Etude sur les 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 series of Arescus histrio, collected in Ecuador by Mr. 

 Buckley, illustrating the extreme and asymmetrical varietal conditions; the Eev. H. 

 S. G-orham and Mr. C. O. Waterhouse also alluded to the same subject. 



Mr. Billups exhibited four species of Pezomachus (noticed as Mulleri, 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. Yincent. 



Mr. Cansdale exhibited examples of Tischeria gaunacella, bred by him from 

 Prunus spinosa. 



Mr. Scott communicated a paper on Hemiptera from Japan. 



Mr. C. O. Waterhouse read a paper on a new species of Polyctenes, 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 * ery ends of the earth to consult the collection of the Uritish Museum, 

 and but for this imp- We .ive necessity of their so doing, who knows whether some would ever 

 have visited Euro*- .11 ? Thus, indirectly, Francis Walker may have conferred a great boon on 



our science.
