Phytomtza ch^rophylli. — The autumn generation of this mining 

 dipteron has occurred with us abundantly in the leaves of Chcurophijlliim 

 temuluoi and 0. syivestre during September and October. The mine is 

 most abundant in C. temulum, though it occurs, but far more sparingly, in 

 C. anthriscas and C. syivestre, as noticed first by Kaltenbach in 187'<i. Tiie 

 larva first makes a somewhat serpentine tunnel in an upper segment of the 

 leaf-divisions, which it afterwards enlarges till the pulp is nearly all 

 consumed, and a conspicuously white patch is all that is left to tell of its 

 earlier life. The larva mostly pupates in the soil below, occasionally even 

 in the mine itself. The tiny pupa is black and glossy, and the fly will 

 doubtless put on wings in the spring of next year. — Peter Inchbald ; 

 Hornsea, Holderness, December 19, 1888. 



Mould. — Can any reader of the ' Entomologist ' suggest a remedy for 

 the prevention of mould? Several specimens in my drawers are slightly 

 affected. One time my cabinet did not oecupy one of the driest situations. 

 I have cleaned the few specimens that were affected by means of a camel- 

 hair brush. Is mould contagious, and are the same specimens likely to be 

 subjected to it again ? A prevention was given some years ago by the Piev. 

 J. Tasker (Entom. xv. 233), but from the experience of Mr. H. Dobson, 

 jun. (Entom. xv. 234), it was injurious to the white insects, turning them a 

 dirty cream colour; by so doing the remedy becomes equal to the disease.

 [Calvert's glacial carbolic acid should be placed on a small piece of cotton- 

 wool on the head of a pin, about the centre of the affected drawer. This 

 will destroy all life, either vegetable or animal, in the drawer, which should 

 be kept tightly closed for a few, days. Mould is a fungoid growth which 

 spreads or returns wherever the spores find a suitable nidus to commence a 

 further colony — J. T. C]

SOCIETIES. 



Entomological Society of London. — December 5th, 1888. — Dr. D. 

 Sharp, F.L.S., President, in the chair. Mr. B. A. Bower, of Eltham, 

 Kent, was elected a Fellow of the Society. Mr. W. F Kirby exhibited, 

 for the Piev. Dr. Walker, a variety of the female of Ornithoptera hrookiana; 

 he also exhibited, for Major Partridge, an undetermined species of the 

 genus Hadena, captured last summer in the Isle of Portland. Mr. R. 

 South exhibited a series of specimens of Tortrix piceana, L., from a pine 

 wood in Surrey; also melanic forms of Tortrix podana, S., from St. John's 

 Wood. Prof. Meldola exhibited, for Dr. Laver, a melanic specimen of 

 Catocala nupta, taken last September at Colchester. Mr. E. B. Poulton 

 exhibited preserved larvse of Sphhix coirvolvuli, showing the extreme dark 

 and lioht forms of the species. Mr. M'Lachlan called attention to a plate, 

 representing species of the genus Agrotis, executed by photography, 

 illustrating a memoir by Dr. Max Standfuss, in the Correspondenz-Blatt, 

 Verein ' Iris,' in Dresden, 1888. He considered it was the best example 

 of photography as adapted for entomological purposes he had ever seen,
