22. Memps viridis, L. (Indian Bee-Eater), (a) Observed 



to catch butterflies in India : Major Nurse, " J. Bomb. 

 Soc," XV, p. 349. — (b) " Col. Swinhoe informs me that 

 in India he has on several occasions seen Merops 

 viridis catch and eat butterflies, and that he has also 

 witnessed many cases of other birds pursuing them " : 

 R. Triraen, Proc. Ent. Soc. Lond., 1897, p. xc. — (c) 

 " Mr. F. Lewis, of the Ceylon Forest Service, . . . has 

 seen Merops viridis occasionally take small white and 

 yellow butterflies {Terias spp.) " : R. Trimen, /. c. xci. — 

 {d) " In the cases [of birds attacking butterflies 

 which] he had witnessed, the Euploeae and Danaidae 

 were caught as often as any others, but usually 

 escaped eventually from the beak of the bird and flew 

 away none the worse owing to the toughness of the 

 integuments. The only bird he had observed fre- 

 quently to pursue butterflies was the Common Indian 

 Bee-Eater, which he had seen hawking Pieridae, and 

 among them Tcracolus" : Sir G. Hampson, Proc. Ent. 

 Soc. Lond., 1897, p. xxxviii (India). — (c) "Another 

 bird that frequently catches these butterflies \_Terias 

 silhetana and T. laeta] on the wing is the Indian 

 Bee-Eater {Merops viridis)" : A. E. Mackav, "Nature," 

 Ixv, 1902, p. 486 (India).— (/) "In one case a Bee- 

 Eater caught a Danais, but dropped it as soon as it 

 had tasted it, and the Danais flew away little the 

 worse" : E. H. Aitken, "J. Bomb. Soc," xvi, 1904, p. 

 156 (India). — {g) Terias hecabe and Papilio pammon 

 " stemed to be the principal victims of the graceful 

 green Bee-Eaters. . . . They never missed their 

 prey, and always brought their quarry back to the 

 same spot to be dis-winged before being swallowed, 

 the ground under their watch-towers being thickly 

 strewn with gaily painted shreds of unfortunate butter- 

 flies and bees " : E. L. Arnold, " On the Indian Hills," 

 i, pp. 247, 248 (1881).— (A) Col. N. Manders informs 

 me that in the year 1900 in Ceylon he observed a 

 Bee-Eater of this species capture a Charaxes 'psapli07i.
