Mr. E. Saunders exhibited a good example of Pachetra leucophcsa, taken by Mr. 

 N. E. Brown from off a gas-lamp at the Red-Hill Station, on 14th May, 1868. 



Mr. Homo (present as a visitor) narrated an account of the antagonism 

 existing between rats and scorpions in India. He had confined the animals under 

 a glass case, in order to observe their movements, and found that the rat invariably 

 disabled the scorpions by seizing them by the tail, after which it proceeded to pull 

 off the legs ; but did not eat the creatures. 



Mr. Pascoe made some observations on the genera Aprostoma, Mecedanum and 

 Qempylodes regarding the possible identity of the genera. He exhibited a species 

 of Hemiptera (perhaps an Odontoscelis) from Toulon, which he could not find 

 described in any work. 



The Secretary read a letter addressed to him by Dr. Butterfield, P. 0. Box 

 No. 1473, Indianopolis, Indiana, wherein the writer expressed his desire to give a 

 tolerably complete collection of the Lepidoptera of his State, in exchange for a 

 similar one of British species. 



Mr. Butler communicated a description of a new species of Hestina from India, 

 which he proposed to call H. Zella. It bears a strong mimetic resemblance to 

 Danais Juventa. 



Professor "Westwood exhibited drawings of a minute insect belonging to the 

 family Aphidce, which was causing great damage of the vineyards of the south of 

 France, and also occurs in England. He had first became acquainted with the 

 creature in 1863, when he received some vine-leaves attacked by it. A puncture 

 being made in the upper cuticle, the wounded part thickens, bulging out beneath, 

 and forming a concavity above, round the edges of which small imbricated scale- 

 like growths are produced, closing over the cavity ; in this nidus the insect pro- 

 duces its young. In the spring of last year he read a paper on the subject before 

 the Ashmolean Society, and applied the name of Peritymhia vitisana. But it is under 

 other circumstances that the greatest damage is done. The same species (for he 

 could detect no difference whatever) is subterranean also, then sucking the ex. 

 tremities of the young root-fibres, thus threatening the life of the plants. Under 

 this condition the French had termed it RhizapMs vastatrix. Dr. Signoret con- 

 sidered it to be a species of Phylloxera. 



Mr. Smith mentioned that he had observed a parallel instance of great 

 diversity of habit in Cynvps aptera, which ordinarily makes more or less agglomerated 

 masses of galls on the roots of the oak. But he had once found small galls formed 

 of imbricated scales on the surface of the principal stem under-ground, and from 

 them had bred an insect which he could in no way separate from the ordinary 

 C. aptera.
