The different species were found from sea level up to 10,000 feet, at 

 which elevation the largest species, L. orestilla, was found. Leuco- 

 tftifris zelica was undoubtedly a mimic of Pierines of the genus 

 Disinorphia, and not a model as might at first sight be supposed. 

 Haensch considered that the species composing the genus could be 

 split up, but while there are minor structural differences, such as a 

 longer, or a shorter hindwing cell, the genus seemed a very natural 

 one. The peculiarly oblique position of vein 5 of the hindwing 

 usually revealed a LeucotJii/ris at a glance. 



Dr. Cockayne exhibited an aberration of Pobiijonia {Grajita) 

 c-albnm, taken in Montgomeryshire, September 7th, 1916, by Lord 

 Oarioch. The two large costal spots on forewing united into a 

 semicircular black patch, and the hindwings are almost entirely 

 suffused with black. 



Dr. T. A. Chapman exhibited examples, males and females, of 

 two pairs of closely related Lycsenid species, one species of each pair 

 having only been differentiated in recent years, viz., Callophrys ruhi 

 and C. avu, from the French Riviera, and Lationna orbituliis var. 

 oberthilri and L. pyrenaica from the Pyrenees. He also showed the 

 double-brooded South European Ayriades, which Dr. Verity dis- 

 tinguishes from A. coridon as a new species, under the name of 

 arayiinensis. Its life-cycle is that of thetis, with two broods, not of 

 coridon, which is single-brooded. The appendages of coridon and 

 arayonenaiH are indistinguishable. 



Mr. Leeds exhibited the following aberrations of British 

 Lepidoptera, taken in 1916 : —

 scarlet. Upperside. Hunts, June 3rd, 1916.

 gins of hindwings reddish-brown. Upperside. Hunts, June 3rd, 

 1916.
