EpiNEPHEi.E JANiRA, ? (27 examined). 



One appeared to have a .-cent as in the <? ; eight were doubtful ; eighteen 



negative. 



Epinepiiele tithonus, (J (81 examined). 



In twenty-three cases the results were negative ; in eight cases doubtful. Even 

 in the case of a <? taken courting no scent could be detected. 



Epinephele tithonus, ? (12 examined). 

 All these gave negative results. 



Pabauge meg^ra, c? (16 examined). 



In three I detected an odour somewhat like chocolate, but very faint ; in six 

 cases the results were doubtful ; in seven negative. At Dr. Dixey's suggestion I 

 examined several males in the house, stroking the " brand " with a camel's hair 

 pencil, but did not obtain satisfactory results. Apparently my sense of smell is not 

 acute enough. 



Pararge MicG^RA, $ (4 exaQiined). 



In one instance the result was doubtful, but in the other three negative. 



Ltc^na ICARUS, (^ (33 examined). 

 In twenty-five cases a distinct scent was detected, in one instance it was strong ; 

 in seven cases the I'csult was doubtful ; in one case only was it decidedly negative. 

 Of a pair taken in copuld the $ had a distinct scent, the ? none. The scent of this 

 Blue is entirely unlike that of the Pierines, and may perhaps be compared to that 

 of chocolate sweetmeats. Two ladies confirmed the reality of the scent. 



Ltcjbna ICARUS, ? (14 examined). 

 Of these nine gave negative results ; four were doubtful ; but one had a distinct 

 scent, and I can only suggest as a possible explanation that this specimen had paired. 



Hespeeia sylyanus, (J (3 examined). 

 Stroking the " brand " gave negative results. 



Speaking generally pinching the thorax did not seem to have any- 

 decided effect, save perhaps in bringing out the very faint odour of 

 the $ napi, but in the case of a few of the Pierines it produced a 

 foul odour, possibly fcecal. 



There are many difficulties in these observations. Wind may 

 interfere ; confusion may arise from tbe scents of flowers or the 

 leaves of plants. Then the scales rubbed off and snuffed up the 

 nostrils are very irritating to the back of the throat (more especially 

 it seems to me in the case of Satyrids), and this irritating quality in- 

 creases the diflBculty of appreciating slight odours. The phenomena 

 are moreover fleeting, and do not admit of demonstration to others. 

 Lastly, the human nose is at best a poor instrument; the sense of 

 smell is soon clogged, while on the other hand scents may linger in 

 the tortuous nasal cavities.
