Dr. G. B. Longstaff s Bionomic Notes on Butterjlics. 617 



Zampides celeno, Cram. (Ceylon, 1908). A minority of 

 the numerous ^ examined had a faint sweet scent. 



Catochryso'ps hanno, Stoll. (Jamaica, Trinidad, Tobago, 

 Colombia, Panama, Venezuela, 1907). One $ was noted 

 to have a very strong, sweet, Frecsia-Vike scent, but most 

 of my specimens of this tiny butterfly appeared to be 

 odourless. 



Polyommatus h^iicus, Linn. (Ceylon, 1908). About half 

 of the $ examined had a slight scent like that of meadow- 

 sweet. 



Polyniphe dumcnilii, Godt. (Venezuela, 1907). Ten ^ 

 of this little black-and-white butterfly gave positive results 

 of a surprising character. In the majority of cases the 

 odour was strong, or even very strong ; moreover it was 

 disagreeable ; and I compared it to horse-urine, but more 

 usually to pig-styes, or, perhaps more correctly, to pigs ! 

 At first it seemed scarcely credible that so small a butter- 

 fly could smell so strongly. My only ^ specimen was 

 odourless. 



Ucvpala lazulina, Moore (Ceylon, 1908). Three males 

 yielded a scent like vanilla biscuits. 



TJiedopsis tepkra^us, Hiibn. (Venezuela, 1907). A strong 

 peculiar, ratlier disagreeable odour was detected in a ^ of 

 this siDecies. 



Tmolics camhes, Godm. and Sal v. (Venezuela, 1907). I 

 noted in a ^ a " treacly smell " ; Mrs. Longstaff compared 

 it to " coarse brown sugar." 



Tinolus palegon, Cram. (Venezuela, 1907). A ^ had an 

 odour of chocolate. 



PAPILIONID^. 



PlERIN^. 



Enantia melitc, Clerck (Venezuela, 1907). The only 

 specimen taken, a ^, had a scent like mignonette. 



Tcrias euterpe, Men. (Jamaica, 1907). I had ample 

 opportunities of studying this very common Jamaican 

 butterfly. Of 21 ^ taken not one was scented, but 31 out 

 of 39 $ indubitably were. Their odour varied from " very 

 slight " to " strong " (17 specimens) ; my wife described it 

 on various occasions as " a slight pleasant smell," " strong, 

 like syringa," "a very soft gentle smell, might be jasmine," 

 and " very slight, sweet, jasmine or syringa." Mr. A. P. 

 Ponsonby who walked with me one day suggested " gorse."
