610 Dr. G. B. LongstafPs Bionomic Notes on Bidterjiies. 



So far, however, as the facts are available it would appear 

 that, speaking generally, the Pierinie and Satyrinas. belong 

 to the first class, or those with attractive scents, whereas 

 the Danainx, Acrmnie and Hcliconiinai belong to the 

 second, or those with repulsive scents. The Ithomiinse, 

 Nymphalinc'e, Lycmnidm and FcqnlionimB contribute to both 

 classes. Of other groups little or nothing is known as 

 regards scents. 



NYMPHALID^E. 

 Ithomiin^. 



TiiJiorca megara, Godt. (Trinidad, 1907). Three $ 

 had a very distinct, or even strong, scent, which was com- 

 pared by both Mrs. Longstaff and myself to Stephanotis, 

 but I thought that it had in addition a spicy, or dusty 

 element. A $ was scentless. 



Athcsis dearista, Dbl. (Venezuela, 1907). A ^ had a 

 slight sweet flowery scent, both alive and dead : it appeared 

 to be associated with the brushes on the hind-wings. 



Levcothyris victorina, Hew., and L. phcmonoe, Dbl. 

 (Venezuela, 1907). A ^ of each of these species had 

 an oflfensive odour, which in the latter case seemed 

 to be associated with the tufts or brushes on the hind- 

 wings. 



Danain^. 



Anosia arcMppiis, Fabr. (Jamaica, Tobago, Panama, 

 Venezuela, 1907). \o^, 2^. All had a scent, similar in 

 quality and intensity in both sexes ; it is described in my 

 notes as " slight," " moderate," or " strong," and is com- 

 pared to that of a cockroach, a musk-rat, a rabbit-hutch, 

 or musty dung ; in two cases it is qualified as " scarcely 

 unpleasant," and " scarcely disagreeable." 



Danaida plexippus, Linn., genutia, Cram. (Matheran, 

 Bombay Presidency, 1908). A ^ had a slight " musk-rat " 

 odour in the field, none at home tliougli still alive.* 



Danaida jamaiccnsis, Bates (Jamaica, 1907). 2^,2$. 

 Of the two males the scent is described respectively as 

 " strong rabbit-hutch odour," and " decided odour, ? cock- 

 roach, scarcely disagreeable." Of the females it is noted 

 " both w'ith a strong cockroach smell, perceptible next day : 

 my wife, however, described the odour as slightly fusty."
