He also exhibited a series of Polia cJii reared from ova 

 deposited by a female taken by Mr. G. T. Porritt in his 

 garden at Huddersfield. The specimens were all unusually 

 dark, the females being of a uniform dark olivaceous grey, 

 with black markings without any white. 



Mr. Sich read a paper entitled, " Notes on Chrysopom 

 {Gelechia) hermannella''' (see p. 43).

Mr. W. J. Kaye exhibited a flower of the remarkable 

 orchid, Masdevallia chimcera, from the mountains of Colombia. 

 The flower, in common with nearly all the genus, was 

 chiefly conspicuous for its developed sepals and the great 

 reduction of the petals. This species, however, had a com- 

 paratively large white two-lobed lip, which was freely move- 

 able and hinged so that the wind could move it. The flower 

 shown had tails to its sepals of just four inches, but what is 

 the use of these tails or of the movable lip there was no 

 record. The species occurred at an altitude of 3-4000 feet, 

 and thus required more warmth than most other species of 

 the genus which occurred at greater elevation. 



Mr. R. South exhibited, on behalf of Mr. Hallam Moore, 

 of Barnet, specimens of Coleoptera mounted on transparent 

 gelatine card, which allowed of easy examination of the 

 under-side of the insect as well as the upper. It was stated 

 that the card only needs to be slightly moistened with warm 

 water before putting on the specimens. The cards were to 

 be obtained at 28, Barbican, E.C. 



Mr. Robert Adkin exhibited a series of Sclcnia bilunaria 

 {illimaria) , reared from ova obtained from a moth taken at 

 Eastbourne on August nth last, together with series of the 

 ordinary spring and summer emergences for comparison. 

 The parent moth had evidently deposited most of her ova 

 before being taken, but a few were obtained between August 

 nth and 14th, which hatched on the 21st. No attempt 

 was made to force the larvae, indeed, it was difficult to obtain 

 suitable food for them, and they had to make shift with some 

 rather hard birch, of which the supply was limited. How- 

 ever, within a month they were all full fed, and pupated 

 between September the 20th and 23rd, the moths emerging 

 between October the loth and i8th. In general appearance 

 they followed the summer rather than the spring specimens, 

 but in some minor details more nearly approximated to the
