 Dr. E. A. Cockayne exhibited a series of Dijaatroma concinnata 

 taken by Mr. E. Y. Horn, at Terbert, on the mainland of Argyle- 

 shire. 



To compare with these were series of D. concinnata, Arran Isle, 

 and melanic aberration, the two Irish concinnata taken by Captain 

 Gwatkin-Williams, R.N., on Achil Island, D. citrata {innnanata) ab. 

 pythonissata from the Shetlands, a varied series from E. Aberdeen- 

 shire, D. tnincata, English and Scottish, and a form from Suther- 

 land showing great resemblance to concinnata. The point of the 

 exhibit is that concinnata has not been taken on the mainland of 

 Scotland since Curtis took it in August, 1835. Mr. Home's series 

 was taken at rest on rocks amongst heather, and no typical tnincata 

 were present. The specimens were taken in July, 1915. 



Mr. Percy Bright exhibited very fine series of striking aberrations, 

 of which the following are the principal forms ; — 



limnicia phlaas. — (1) An underside right hindwing with markings 

 of upperwing reproduced. (2) An underside having very dark 

 hindwings with striated markings in lighter colour. 



Arctia caja. — (1)A graduated series of aberrations from a 

 magnificent specimen with forewings wholly cream coloured, except
