610 Dr. G. B. Lon^aflTs Bionomic Notes on Butterjlies. 



So far, however, as the liicts are avaihible it would appear 

 that, speaking generally, the Pivrimv and yiatijnnK, belong 

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

 the Danaina}, Acriuinie and Heliconiinm belong to the 

 second, or those with repulsive scents. The Ithomiinie, 

 Nymphalinfp, LycmnuL'e and Vainlioninx contribute to both 

 classes. Of other groups little or nothing is known as 

 regards scents. 



NYMPH ALID^E. 

 Ithomiin^. 



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

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

 pared by both Mrs. Longstatf ami myself to Stephanotis, 

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

 element. A $ was scentless. 



Athesis dcarista, 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. 



LcHcuthyris 'cidorina, Hew., and L. I'^icmonoe, Dbl. 

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

 an offensive odour, which in the latter case seemed 

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

 wings. 



Danain^. 



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

 Venezuela, 1907). 15^, 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 ple.vi2')2ni-'i, Linn., gcniUia, Cram. (Mathenin, 

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

 odour in the field, none at home though 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 with a strong cockroach smell, perceptible next day : 

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