848 ME. I!. I. POCOCB c\ THE 



Bombus-like Fly [Arctophila mussitans). 



See l>elow, pp. 851 and 853. 



Fly like a small Bombus (Chilosia ilhistrata). 



See below, pp. 854 855. 



Spiny Fly (Echinomyia ferox). 



July 31, 1909. One (dead) taken by female Tanager, but after 

 a good deal of pecking, was left. A Black-headed Sibia then 

 tried it and finally ate it. 



One also eaten by Sulphury Tyrant (see below, p. 855). 



Daddy Loxg-legs {Tipula oleracea). 



Oct. 26, 1909. One taken from my hand and eaten readily by 

 Dial Bird ; one taken and eaten, but not so readily, by a second 

 Dial Bird ; one eaten greedily by Fantailed Flycatcher. 



One of these specimens of Tipula was taken twice by the 

 Harmonious Shrike-Thrush, but was dropped on both occasions. 

 Another was taken three times by Black-winged (Jrackle, but was 

 not eaten. 



The rejection of this insect by the Shrike-Thrush, which ate 

 almost every insect other birds refused, was very surprising. 



Fly {Empis tessellatd). 



July 31, 1909. Two (dead). Eaten greedily by the Dent's 

 Monkey that toot the Thanaos tages with avidity (p. S31 ). 



Order HYMENOPTERA. 



Tipula-like Ichneumonid [Ophion luteus). 



(Nocturnal species, mahogany-red in colour, with 



\ ery tough integument.) 



Oct. 26, 1909. One taken and tried perseveringly by Fantailed 

 Flycatcher, but ultimately abandoned. Also tried but soon given 

 up by Yellow-crowned Hangnest; taken and after a little pulling 

 about swallowed entire by Dial Bird. 



Nov. 7, 1909. — Taken by Black winged Grackle; but so hard 

 was the insect that it shot away out of his beak. The bird 

 pounced on it at once on the sandy Boor of the aviary and 

 ate it ; but if the insect had not been very lethargic, or if it 

 had fallen amongst the undergrowth, it might have escaped 

 him. Hence probably the significance of its hard slippery 

 exoskeleton.
