describe the larva which he reared ? If so, did it agree with the 

 continental descriptions of P. farfara larvae ? or did it materially 

 differ from P. gonodactyla larva of the first brood ? If it agreed 

 with P. farfara, and did not materially differ from P. gonodactyla, 

 it would go a long way to bearing out Mr. South's suggestion 

 that it may be a " seasonal form " of P. gonodactyla, or in other 

 words that it is to be referred to the second brood of P. 

 gonodactyla, for such I take this phrase to mean. Again, have 

 the continental authorities noted P. gonodactyla as double - 

 brooded? and does P. farfara, of Zeller, appear on the Continent 

 in the same places as P. gonodactyla, and at a time corresponding 

 with a second brood of that species ? — J. W. Tutt ; Rayleigh

Fossil Insects. — At a meeting of the Geologists' Associa- 

 tion, held at University College on the 5th of June last, Mr. 

 Herbert Goss, F.L.S., F.G.S., read a paper " On some recently 

 discovered Insecta and Arachnida from Carboniferous and 

 Silurian Rocks." After remarking on the great number of 

 Palffiozoic insects lately discovered, and calling attention to the 

 recent investigations and writings on the subject of M. Chas. 

 Brongniart, Dr. Deichmiiller, Dr. Dohrn, Dr. Fritsch, Dr. 

 Eugen Geinitz, Dr. H. B. Geinitz, Dr. Goldenberg, Dr. Hagen, 

 Prof. Lindstrom, Dr. Novak, Mr. B. N. Peach, Mr. Scudder, and 

 Dr. Sterzel, the author stated that at the date of his last paper in 

 March, 1879, only 103 fossil insects from the Carboniferous 

 rocks of the whole world were known ; but that during the last 

 five years a large number had been discovered, including about 

 1400 from the Coal-measures of Commentry, France, and a few 

 from Saarbriick, Kleinopitz, Lugan and elsewhere in Germany, 

 and a considerable number from various parts of the North 

 American continent. Such of the specimens as had yet been 

 determined were then enumerated, some of the most remark- 

 able forms were referred to in detail, and attention was drawn 

 to their affinities with existing types. According to M. Brong- 

 niart, the Commentry fossils included about forty types. The 

 Hemiptera are represented by genera allied to Fulgora, Lystra 

 and Membracis; the Neuroptera by forms approaching Corydalis, 

 Chauliodes and H erne rob ius ; the Pseudo-Neuroptera by types 

 closely allied to Ephemera and Perla; and the Orthoptera by 

 Blattidce and Phasm'uhe. Many of these fossils, could not,
