to detect any scales specialised for scent distribution. He 

 was not at present prepared to assert, from his observations in 

 the field, that the repulsive odours were in all cases con- 

 fined to the tissues and juices of the body ; though in some 

 instances the intensity of such odours was certainly increased 

 when the thorax was crushed. 



Mr. W. G. Sheldon exhibited a collection of Rhopalocera 

 made by him in Spain during July and August, 1905, 

 including Ar(jynms adippe, vars. cldorod\-ppe and cleodiirpe, 

 together with typical European specimens, and var. cleodoxa, 

 for comparison ; an aberration of A. aglaia, with the black 

 blotches on the superior wings enlarged and banded, and 

 with dark suffused ground colour on all wings ; Melancmjia 

 lachesis, with var. canigidensis, and ab. catahuca, Erchia 

 stygne, var. ^je/la^twci^, with Swiss type for comparison ; 

 Brenthis hecate ; Clirysoplianus virgaurex, var. miegii, with 

 French typical specimens for comparison ; and Leesopis 

 roboris, all from La Granja, in the Guadarrama mountains ; 

 ScUyrus jn'ieui'i and $ var. uhago7ii, and intermediates, 

 Upinephele lycaon, ? , Melitaxi didyma, Erehia zapateri, with 

 French specimens of E. neoridas for comparison ; Lyaena 

 hylas, var. nivescens, with type for comparison ; and L. 

 corydon and vars. Msp>ana and polonus with intermediates 

 between all these forms, and also British, Fi-ench, and Swiss 

 typical specimens for comparison. The last-named species 

 were collected in the Albarracin Sierra in Arragon. 



Commenting on these exhibits, Mr.SiiELDON said : — " The E. 

 zapateri show considerable variation in the spot markings 

 of the inferior wings, sometimes without any red and thus 

 typical ; whereas others have single red spots, and others a 

 small red band, inclining towards the French forms of the 

 nearly allied species E. neoridas. 



" The Ejnnephele lycaon, female, are striking, the anal 

 ocellus which in European specimens is usually slightly 

 smaller than the costal ocellus in the Spanish specimens, is 

 distinctly larger, and in one or two it shows a strong tendency 

 to invade the surrounding light area, suffusing it with the 

 black of the ocellus. 



"The Lycscna corydon taken and exhibited are very interest-
