Vandeventer Flat. Observed in some numbers at Cabezon and 

 Snow Creek in May, and at Banning in June. In the late sum- 

 mer they became still more numerous, and more widely spread, 

 being met with at as high an elevation as Tahquitz Valley (8000 

 feet), where two were seen on July 20. Particularly abundant 

 at Hemet Lake. August 5-15, where they were feeding in the 

 open meadows surrounding the lake. 



Four specimens were preserved, one from Cabezon, May 24 

 (no. 2131), two from Snow Creek, June 1 and May 31 (nos. 

 2147. 2148), and one from Hemet Lake. August 9 (no. 2986). 

 The last mentioned, an adult female, is in exceedingly frayed 

 plumage, but has not yet begun to molt. 



Myiarchus cinerascens cinerascens (Lawrence) 

 Ash-throated Flycatcher 



An abundant migrant throughout the region, and breeding 

 commonly from the base of the mountains at least as high as 

 Strawberry Valley (6000 feet). A pair was seen at Garnet 

 Queen Mine. 6(100 feet, where it was probably nesting, but others 

 observed a few days later on the summit of Santa Rosa Moun- 

 tain, 2000 feet higher, were, with little doubt, wanderers from 

 lower points. At Cabezon, early in May, and at Dos Palmos the 

 end of May. they were migrating in considerable numbers. At 

 Kenworthy. June 8, a pair was seen carrying building material, 

 and on June 14, in Palm Canon at about 3000 feet, an occupied 

 nest was found. By the first week in July the young began 

 to appear. 



In August migrating birds were abundant, at Hemet Lake. 

 Dos Palmos and Vallevista, a large proportion evidently young 

 of the year. 



Twenty-five specimens were collected: Snow Creek, three 

 (nos. 2149-2151), Cabezon, three (nos. 1679-1681), Schain's 

 Ranch, five (nos. 1926-1930), Fuller's Mill, one (no. 2000), Dos 

 Palmos, five (nos. 2496-2500), Strawberry Valley, five (nos. 

 2586-2590), Hemet Lake, two (nos. 2983, 2984). Vallevista, one 

 (no. 3127).
