but the stinkbugs (Pentatomidse) were contained in the most 

 stomachs. 



Diptera (flies) appear to be more popular than bugs with Say's 

 phcebe. The aggregate is 16.67 per cent, while for the eight months 

 in which they were eaten the average amount is 25 per cent. The 

 kinds eaten are mostly of the families of the house fly, the crane fly, 

 and the robber fly. One stomach was entirely filled with members 

 of the house-fly family (Muscidse) . 



Caterpillars and moths amount to 12.12 per cent of the diet of 

 Say's phoebe. Here for the first time is found a flycatcher that eats 

 more of the adults (moths) than it does of the larvae (caterpillars). 

 The former were found in 19 stomachs and the latter in 17. None 

 were in the stomachs of July and August^but as only three stomachs 

 were collected in those months, the record can not be accepted as 

 final. Most of the other months show a fair percentage, and May 

 and June appear to be the months of greatest consumption. Grass- 

 hoppers and crickets seem to be well liked, as they occurred in 48 stom- 

 achs, were the total contents of one, and amount to 15.36 per cent 

 of the food. They are probably eaten in every month, but none 

 were found in the few stomachs taken in January, June, and July. 

 The average for the nine months in which they occur is over 20 per 

 cent. Dragon flies, spiders, millepeds, and a few sowbugs, together 

 amount to 4.79 per cent of the food, and make up the remainder 

 of the animal quota.
