and Buchanan White Lycopsis arvensis, bugloss ; in this case 

 also there could be no cryptic resemblance, since artaxerxes, 

 though one of the " blues," had not a particle of blue about 

 it on either the upper or under side. 



Mr. SiMES said that at Brindisi he had noticed the special 

 fondness of Melanargia arge for purple flowers. 



Prof. PouLTON observed that the fondness of certain Pierines 

 for yellow flowers might be accounted for on cryptic grounds ; 

 he also mentioned Lord Avebury's observations on bees and 

 the colour of flowers. He further said that it had been 

 observed by Prof. Meldola that the ? ? of several British 

 butterflies that carried the c? (^ in the nuptial flight were 

 more brilliantly coloured than the other sex. 



The Rev. G. Wheeler said that he had paid a good deal of 

 attention to this point for some years, and that the result of 

 his experience was that in the Lycaenids the <? always carried 

 the ?, while in other Families, except the Hesperidae, none 

 of which he had ever seen in flight when paired, the ? carried 

 the S- Speaking from memory he could say with certainty 

 that this was the case on the one hand with Plebeius argus 

 (aegon), P. argyrognomon, Polyommatus icarus, Agriades 

 corydon, and A. thetis, and on the other with Dryas paphia, 

 Argynnis adippe, A. aglaia, Pararge aegeria, Epinephelc 

 jurtma, Aphantopus hyperanthus, Coenonymplia pamphilus, 

 Melanargia galatea, and the common Pierids. WTiat had 

 specially struck him was that he had never seen a single 

 exception to the rule. He suggested that it was rather a 

 matter of weight than of colour, the $ being generally smaller 

 than the cj among the Lycaenids, whilst in other families it 

 was usually the larger, often conspicuously so. 



Mr. H. J. Turner said that in all cases that he had noticed 

 the $ carried the ^, but that he had never seen paired Lycaenids 

 in flight. 



The President entirely endorsed Mr. Wheeler's observa- 

 tions as to the Lycaenids, having seen the ? of various species 

 carried by the o. 



With regard to colour forming an attraction to the ?, 

 Dr. Cockayne commented on the fact that at Royston, 

 where the o' A. corydon was so scarce that every specimen
