610 Dr. G. B. LoDgstaff's Bionomic Notes on Butterfiies. 



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

 that, speaking generally, the Picrime and Satyrin/v belong 

 to tlie first class, or those witli attractive scents, whereas 

 the Danain^, Acrxinm and Heliconiinie belong to the 

 second, or those with repulsive scents. The Ithomiinse, 

 Nymphalin^, LycienidiB and Papilioninge contribute to both 

 classes. Of other groups little or nothing is known as 

 regards scents. 



NYMPH ALID^. 



iTHOMIINiE. 



Tithorea 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. 



Athesis dcarista, Dbl. (Venezuela, 1907). A $ had a 

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

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



Lcucotliyris vidorina, Hew., and L. phcmonoe, 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 arcJiipp^is, 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 plexipptcs, Linn., geniUia, Cram. (Mdtheran, 

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

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



Danaida jamaicensis, 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."
