1 84 THE YOUNG NATURALIST. 



August 8th, 1889.— The President in the chair. Mr. Dawson exhibited a speci- 

 men of Deilephila Uvornica, taken in the neighbourhood of Plymouth, t888, a melanic 

 form of Tceniocampa instabilis, taken at Plumstead, and two vars. of Polyommatus 

 phlces, one being the var. Schmidtii, taken at Plumstead. Mr. Carrington knew of 

 three or four examples of this var. having been taken during the last ten or fifteen 

 years. Mr. Tugwell remarked that he did not altogether agree with Mr. Carrington, 

 that the var. Schmidtii was so rare, he thought that in nearly all the principal col- 

 lections there were forms approaching this variety. Mr. Carrington, in reply, said 

 he only knew of four such as the one exhibited. Mr. Dennis, forms of Bryophila 

 perla, including several yellow specimens and one having the superior wings almost 

 entirely suffused with black. Mr. R. Adkin, a specimen of Chcerocampa porcellus, bred 

 from a larva found last year and which was put in a box without any earth and had 

 spun a cocoon some way from the bottom of the box within which it pupated. Mr. 

 Joy, a var. of Epinephek hyperanthus, having the spots on the under side unusually 

 large. Mr. Turner, a larva of Dicvanuva vinula, affected by some disease which Mr 

 Tugwell said appeared to be of a fungoid nature. Mr. Billups a female example of 

 Bracon roberti, taken in his garden at Peckham, also series of Ascogaster varipes (both 

 sexes), and A. instabilis, and read notes ; also galls on Salix herbacea, and their maker 

 Nematus herbacea. The Secretary, on behalf of Mr. T. D. A. Cockerell, two galls found 

 at West Cliff, Colorado, on the wild rose, one Rhodites bicolor, and the fly bred from 

 the other, Mr. Cockerell proposed to name Rhodites roscufolii. A communication was 

 also read from Mr. Cockerell on " Bees and Poppy flowers." Mr. Hall mentioned 

 that below Reading he had seen an albino specimen of the Sand Martin (Cotyle 

 riparia). — H. W. Barker, Hon. Sec.

Publication Received. 



The York Catalogue of British Mosses.* 



We have received a copy of this neatly printed and carefully arranged pamphlet. 

 It will prove an invaluable aid to collectors of this humble, and hitherto rather over- 

 looked branch of our native Flora. The great increase in the number of species and 

 varieties noted of late years, shows what an ample field there is for industrious 

 search in this lowly but attractive branch of botany. It is notorious how enthusi- 

 astic moss collectors become, and this brochure will prove a ready means of intro- 

 ducing their wants and wishes to each other. To the young devotee, the absence of 

 a census table to denote the comparative rarity or frequency of a species, will be 

 rather a drawback; as he is thus furnished with a ready means of appraising the 

 relative value of his " find." But this is an omission that Mr. Wheldon looks for- 

 ward to being remedied at no distant date, and in the meantime all who wish to 

 interchange specimens of mosses will find his list of incalculable service.
