majority of cases are those of normal females. It has been pre- 

 viously shown that there is evidence of direct descent of 

 predominantly male type of gynandromorphism by Schultz who 

 bred 4 Lymantria dispar, which were male in all respects except for 

 splashes of female colour on the wings, from 85 pupc^. One of 

 these males was paired with a normal female, and out of 65 pup^ 

 of the brood, 2 similar gynandromorphs were bred. 



Mr. H. E. Page exhibited a series of local races of Pleheiasar<jHs 

 {(Cf/on) from Abries in the French Alps, Sion and Berisal in the 

 Swiss Alps, and from Pajares and Brauuelas in Spain. The last 

 were of the remarkable form named by Dr. Chapman var. 

 casaiacus, and were taken by Mr. and Mrs. Page in August, 1914. 



DECEMBER lOth, 1914. 

 Mr. a. E. Gibbs, F.L.S., F.E.S., Vice-PreMdent, in the chair. 



Mr. W. Schmassmann, F.E.S., was elected a member. 



Mr. W. J. Lucas read a paper on the "British Longhorned Grass- 

 hoppers," and illustrated his remarks with a series of lantern slides 

 of all the native species. (See page 49.) 



Mr. W. J. Kaye exhibited a plant of ('>rnbanche nrinor, the lesser 

 broomrape, that had come up in a pot of Salvia which was being 

 grown in a glasshouse at a temperature of 65°. The plant was a 

 little drawn, but was otherwise vigorous and healthy. The soil had 

 been taken from the garden, and it Avas somewhat of a mystery 

 where the plant came from. It was known to be parasitic on a 

 number of plants, including ivy. 



A further exhibit was a beautiful hybrid (Jattleya — C. nafcBlcc-alba, 

 the result of crossing C. aiirea with C. tiuuuc-alba. The lip of the 

 flower retains the aurea coloration, but reduced in intensity, 

 while the sepals and petals take the pure white of the trUnm-alba. 



Mr. H. Moore exhibited a drawer of Decticinid^e containing 

 Decticus albifrons, Fab., the largest European species, from Spain, 

 where at times it is very destructive ; D. intermedius, Fab., and D. 

 tessellatus, Fab., also from Spain, the former being very common 

 near Cadiz ; D. rerrncivonis, Linn., chiefly from Savoy. In the 

 pasture above the Monastery of La Grande Chartreuse any number 

 might have been taken. Also Platycleis ijrisea, Fab., from the South 

 Coast of England and a number of French localities. 



Mr. Step exhibited the fungus Tremella niemiterica, growing on
