ABSTRACT OF PROCEEDINGS. 



FEBRUARY 'iOth, 1921. 

 President, K. G. Blair, B.Sc, F.E.S., in the Chair. 



Mr. Hugh Main exhibited a contrivance he was trying in hig 

 breeding pots to keep the earth damp and at the same time to avoid 

 staleness and mould. It consisted of a sheet of glass inserted in 

 his glass vessel dividing it vertically into two chambers, one of 

 which contained the earth for the burrow and pupation hollow, 

 while the other chamber contained only sand which was kept moist. 

 The influence of the moist sand would be exerted at the bottom and 

 sides of the partition. 



Mr. Robert Adkin exhibited a specimen of Fieris brassicae in 

 which the black tips of the forewings were radiated by yellow streaks 

 on the veins; it was taken at Eastbourne on August 17th, 1920, 

 and was similar to the form taken on the same spot on August Sth, 

 1917, which was also exhibited together with a typical specimen 

 for comparison [Froc. S. L. E. and N. H. S., 1917, p. 64). He said 

 that so far as he was aware, only one other specimen of this form 

 was known, the one taken by Mr. P. G. Whittle at Southend in 

 July, 1900— {Froc. 8. L. E. and N. H. S., 1918, p. 58). 



Mr. Hy. J. Turner exhibited a short series of Selidosema plumaria 

 (ericetaria) from Co. Tyrone, Ireland, including a curious dark 

 streaked form of the male, which he had received from Mr. T. 

 Greer of Stewartstown. It was a recurrent form and apparently a 

 step tov/ards the melanic form described by his correspondent in 

 1919 in the Ent. Record, vol. xxxi., p. 74, and named fionoHa. He 

 was naming this form as intermedia-fuinosa. 



He also showed a hybrid (?) Zijijaena {jilipendnlae-lonicerae) sent 

 to him by Mr. Greer and captured at Tamnamore, Co. Tyrone, 

 where the two species were found flying together on the same 

 ground. The specimen had more the shape of lonicerae with 

 antennae of the same. It was of the general shape of this species 

 too, but was six spotted. The black margin of the hmdwings was 

 between the two species in width, and the suffusion in and around
