(a) " I have on several occasions seen butterflies 

 captured by birds and have seen dragon-flies dart 

 after them " : C. V. Riley " 3rd Missouri Report," 

 1871, p. 167.— (/^) "Mr. Otto Lugger of Chicago, 

 while on the U. S. Lake Survey, once saw a bird 

 dart after an archippus [ = plexippus] butterfly, 

 seize it and immediately drop it without devouring 

 the body": C. V. Riley,"/, c. p. 169, note.— (c) " But 

 butterflies are certainly sometimes eaten with us, for 

 several cases are on record where capture has been 

 seen, and I have myself noted one instance where 

 JEuphoeades troilus was unquestionably captured at no 

 great distance from me by a bird. . . . Nearly all the 

 > prominent instances that have been mentioned have 

 been taken from the tropics, where I have no doubt 

 the perfect butterflies form a not inconsiderable por- 

 tion of the food of many birds " : S. H. Scudder, 

 " Butterflies of Eastern U. S. and Canada," p. 1612. — 

 (d) " Turnus [= Fapilio glaucus, L.] has many-
