We may now proceed to discuss the insects which are in- 

 cluded under the above headings, but they will be dealt with 

 under their respective orders. 



Bees, Ants and Ichneumon Flies, &c. (Hymenoptera). 



Humble Bees (Bombus spp.). — These were found in negligible 

 numbers, there being but n records. The Blackbird, Great 

 Tit, Red-backed Shrike and Spotted Flycatcher are re- 

 sponsible for these. It is quite certain that these insects do 

 not represent the principal supply of insect food. 



Hive Bee (Apis mellifica). — These insects are eaten both 

 by the Blue Tit and the Great Tit, but I have not been able to 

 ascertain if these birds capture living examples ; though, if one 

 may rely implicitly upon the statements given in the journals 

 devoted to apiculture in this country, there should be no doubt 

 in the matter. Further particulars regarding this subject will 

 be found on pp. 31-3. 



Wasps (Vespa spp.). — The remains of two species were found 

 in the stomach of a Spotted Flycatcher, but whether this bird 

 feeds habitually upon these pests it is impossible to say. 

 Seeing that the remains of a Humble Bee were found in another 

 individual it is highly probable that these insects may form 

 part of its regular food supply. Further proof is needed, 

 however. 



Ants (Formicidae) . — These were found in very few instances ; 

 but, in point of individuals, they occurred in large numbers in 

 the stomachs of the Green Woodpecker and the Common 

 Sandpiper. 



Gooseberry Saw fly (Nematus ribesii). — The stomachs of 

 three Cuckoos, Nos. 459-461, were found distended with the 

 destructive larvae of this insect. Judging from the total absence 

 of these larvae from the stomachs of other insectivorous birds 

 one may infer that they are generally distasteful. That the 

 Cuckoo feeds very largely upon them and other allied species 

 is, I think, conclusively proved by these records. Unfortunately 

 this bird is comparatively scarce and not of very confiding 

 habits ; but this is not to be wondered at seeing that it is so 

 often shot when it ventures into our fruit gardens and orchards. 



Gall-making Insects (Cynipidce). — Tits (Paridae) feed upon 

 these insects, and, judging by the number of individuals found
