grounds for believing this to be a distasteful genus, alid it is 

 noticeable that both sexes emit on pressure a yellow or greenish 

 juice like that of an Acnva. I was never able to convince 

 myself that any odour attached to this juice, or, except in one 

 case (a female) to the crushed body. But it is quite jwssible 

 that an observer with a more acute sense of smell than I 

 possess might arrive at a different result. The disagreeable 

 odours of the Euijloea group are well known, but Wood-Mason 

 {loc. cit.) records that in Euplo&a {Danisepa) rhadfjYnantlms, 

 Fabr., ' the eversible caudal rosettes of the males are finely 

 vanilla-scented.' A still moi'e conclusive instance, also noted 

 by Wood-Mason, is as follows : — ' The gland covered by a 

 patch of modified scales and l)y an erectile wisp of hairs on 

 each hind-wing in the male (of SticUoplithalma camadeva, 

 Westw.) secretes a fluid that gives out a pleasant odour dis- 

 tinct from, but so faint ns to be barely perceptible ia the 

 presence of, a much stronger odour (resembling that of sable 

 fresh from the furrier's shop), which is common to the two 

 sexes.' 



" A point of much interest in connection with these scents, 

 their diverse characteristics and presumably diverse signifi- 

 cance, is the probability thus suggested of a certain corre- 

 spondence between human aesthetic preferences and those of 

 some at least of the lower animals." 



The general character — agreeable or the reverse — of the 

 odours emitted by the various species shown, as also the 

 property belonging to some of them of exuding a yellowish 

 or greenish fluid on pressure, was indicated in the exhibit by 

 means of coloured labels. 



The Eev. A. E. Eaton inquired whether the coloured juice 

 was exuded from any particular pore, and suggested that when 

 crushed it would be worth while to put the specimen into a 

 solution of formaline, as he had noticed that in some species 

 under this treatment certain pores of the antennfe were 

 extriaded, and that the liquid came, not from the air tubes, 

 but from some special processes. 



Mr. G. C. Champion mentioned that he had observed a 

 fluid exuding from the thorax of many Anthrocerids, and Dr. 

 G. B. LoNGSTAFF Said that he had found the expression of
