large winged white ants. By actual count there were forty-three 
of these and many of them were still alive, although it was at 
least fifteen hours since they had been captured by the nighthawk. 
At Bluff lake in July large numbers of nighthawks made their 
appearance over the extensive meadow just after sundown, and it 
was here that we obtained the majority of the series of seventeen 
specimens secured. Male birds were seen or heard flying about 
above the pines at almost any hour of the day. A few individuals 
were discovered roosting lengthwise on pine branches. Night- 
hawks of this species also appeared in the evening over Bear lake. 
They were not noted however further on the desert side of the 
mountains than Baldwin lake, where one was heard on the eyen- 
ing of August 8, 1905. At the cienaga at the north base of 
Sugarloaf nighthawks were common, August 19 to 22 of the same 
season. On the morning of August 20 at 7 o’clock I saw twenty- 
six nighthawks flying east in a seattering flock high overhead. 
This was doubtless a migratory movement, for none were seen 
anywhere in the mountains after August 23, when I took a full- 
grown juvenal at the same place. August 28 to September 3, 
where nighthawks had previously been so plentiful around Bluff 
lake, we saw none. 
The new race hesperis described by me in The Condor (Vol. 
VII, Nov. 1905, p. 170) was based on my San Bernardino moun- 
tain series of skins. The type was shot at Bear lake, July 30, 
1905. As previously intimated in. the original description, I 
feel confident that this is the race occurring all along the Pacific 
coast region, from the San Bernardino mountains, through the 
Sierra Nevada to Oregon and Washington. 
Chordeiles acutipennis texensis (Liaawrence). Texas Nighthawk. 
The Texas nighthawk was common in the wash at the mouth 
of the Santa Ana Canon near Mentone, June 11, 1905. At Cush- 
enbury springs, 4000 feet altitude, August 9 to 14, the species was 
also numerous and two adults were taken. One of them con- 
tained in its stomach four of the immense seyven-lined June 
beetles. At Cactus Flat, 6000 feet, a pair was seen on the even- 
ing of August 16, and an adult male secured. Finally a specimen
