Page 247 - Spiders, and perhaps to the second pair of antennas of Crustacea. 3. Since the possibility that a number of segments in the germinal streak of different Arthropods have disappeared is not excluded, a homology of the mouth-parts of the different classes of Arthropoda cannot at present be set up. 4. The abdominal appendages of the Insectan germinal streak (including the cerci) are homologous with the thoracic legs. Herein it makes no difference whether these appendages are attached to the middle, at...
Page 246 - The pocket remains open but a short time, but there is a long depresssion of the upper end of the bunch of cells ; the mass of cells is soon cut off from the ventral plate and they are then free in the body cavity, but remain in contact with the ventral plate at the point where they were produced. Later stages show that these cells produce the generative organs ; the generative organs thus appear to be produced by an infolding of the ectoderm, or possibly of the blastoderm, before the ectoderm is...
Page 156 - All the larvae were shown upon a white paper background, but examples of the surrounding twigs which produced the change of colour were shown beside each batch. Mr. Merrifield made some remarks on the subject. Mr. E. Meyrick communicated a paper entitled " On Pyralidina from the Malay Archipelago.
Page 184 - Mr. Hampson raised an important point as to what was the legal " date of publication " of part i. of the Transactions of the Society, 1894. He pointed out that the question of the priority of the names of certain new species described therein would depend upon the date of publication. A long discussion then ensued, in which Dr.
Page 293 - If I had wondered at the zeal for oviposition in these husbandless Solenobice, how was I astonished when all the eggs of these females, of whose virgin state I was most positively convinced, gave birth to young caterpillars, which looked about with the greatest assiduity in search of materials for the manufacture of little sacs.

Mr. Champion and Mr. Blandford made some remarks on the species.— Mr. McLachlan, FRS, exhibited for Mr. JW Douglas male specimens of a Coccid (Lecanium prunastri), bred from scales attached to shoots of blackthorn (Prunus spinosa) received from Herr Karel Sul9, of Prague.
Page 76 - The larvae and the nymphs, although they live under water and must respire, have no branchiae or any external organs by which they can breathe. Their method of respiration is unique ; they breathe with their intestines. The large intestine is covered with numerous tracheae, and when the animal wishes to breathe it opens the orifice of the intestine and admits a quantity of water. This, of course, contains air mechanically suspended, which is taken up the tracheae just mentioned.
Page 183 - Caeacia podana, Scop., reared from larvae feeding on Lapageria and palms in Messrs. Veitch's conservatories in King's Road, Chelsea, including some very dark varieties. The Hon. Walter Rothschild stated that he had taken the species on lime. Mr. Hampson and Mr. Tutt also made some remarks on the habits of the species. — Mr. C. Fenn exhibited a long series of Selenia lunaria, bred from one batch of eggs, which included both the spring and summer forms; and also two unforced specimens, which emerged...
