[Vol. IV. 



and no other food. Six stomachs, collected by Dr. B. H. Warren 

 on the St. Johns River in Florida, contained numerous palmetto 

 ants {Campanotus escuriens), and remains of other ants, several 

 larvse of a Prionid beetle {Orihosotna brunnea), numerous builder 

 ants {Cremastogaster lineolata), one larva of Xylotrechtts, and one 

 pupa of the white ant {Termes). The insects were determined 

 under Professor C. V. Riley.* 



Seeds and berries of the iollowing plants were found in the 

 stomachs examined by the division : — 



[Parthenocissus 



Sourgum {Nyssa aquaticd). 

 Flowering dogwood {Cornus florida). 

 Black haw {Viburnum prunifolium). 

 Cassena {Ilex cassine). 

 Hackberry {Celtis occidentalis). 

 Persimmon [Diospyros virginiand). 

 Wild grapes {Vitis cordifolia). 



Virginia creeper 



quinquefolia). 

 Greenbrier {Smilax rotundifolia 



and S. glauca). 

 Sumac {Rhus copalhna). 

 Poison sumac {Rhus vernix). 

 Poison ivy {Rhus radicans). 



In addition to the seven species of woodpeckers whose food has 

 been already discussed, fifty-seven stomachs have been examined, 

 belonging to twelve species and sub-species, mostly from the 

 southern and western parts of the United States and British 

 Columbia, as follows :

With such a small number of stomachs it is hardly worth while 

 to discuss the food of each species. The Three-toed Wood peckers 

 {Picoides), however, deserve passing notice, since their food contains 

 a larger percentage of wood-boring larvae than any other wood pecker 

 examined. As the food of the two species is practically the same, they 

 may be considered together. The contents of the ten stomachs con- 

 sist of animal matter, 83 per cent. ; vegetable matter, 17 per cent. It 

 is a question whether this should not all be considered as animal, for 

 the vegetable portion consisted almost entirely of rotten wood and 

 similar rubbish, probably taken accidentally, and is not in any proper
