848 MR. B. I. POCOCK ox THE 



Bombus-like Fly [Arctojyhila micssitans). 

 See below, pp. 851 and 853. 



Fly like a small Bombus (Chilosia illustrata). 

 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 Tj-rant (see below, p. 855). 



Daddy Long-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 Flycatchei-. 



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 Grackle, but was 

 not eaten. 



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

 almost every insect othei- birds refused, was veiy surprising. 



Fh" [Empis tessellcUa). 



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

 Monkey that took the Thamios tages with avidity (p. 831). 



Order HYMENOPTERA. 



Tipula-like Ichneumonid [Ophion luteus). 



(Nocturnal species, mahogany-red in colour, with 



very 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 sw-allowed 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 sand}^ floor of the aviary and 

 ate it ; but if the insect had not been very lethai-gic, or if it 

 had fallen amongst the undergi'owth, it might have escaped 

 him. Hence probably the significance of its hard slippery 

 exoskeleton,
