Miami, Mariposa County, California. Altitude, 4,200 feet; Sep- 

 tember 3. A few specimens were taken on a hillside in a conifer 

 forest. 



Ahwahnee, Madera County, California. Altitude, 3,700 feet; 

 September 3. In a large patch of tar weed and other high plants collect- 

 ing was found to be extremely productive, and several species were found 

 which had not been met with in the higher parts of the Sierras. Had 

 more time been available there is but little doubt that a very interest- 

 ing series could have been taken. This was by far the best locality 

 for collecting between Wawona and Raymond. 



From the Yosemite Valley to the Mariposa Sequoia grove the roads 

 are bordered by great open conifer forests, in which Trimerotropis 

 fallax and Trimerotropis cwruleipes were found almost invariably 

 plentiful. In this region collecting was done at Wawona, altitude 

 4,000 feet, September 1; at Mariposa Grove, altitude 7,000 feet, 

 September 2; at Grouse Creek, altitude 6,000 feet, September 1, and 

 at Eight Mile Camp, altitude 5,000 feet, September 1. All of these 

 localities were much the same for collecting. 



Sentinel, Yosemite Valley, Yosemite National Park, California. 

 Altitude, 4,000 feet; August 31-September 1. In the heavy grass 

 near the hotel Melanopli were found in small numbers, while on the 

 opposite side of the Merced River many more were taken in a similar 

 location. In the pine woods of the valley bottom several species of 

 Trimerotropis were taken, and in one clearing dotted with low bushes, 

 in the direction of the Yosemite Falls, a series of Trimerotropis koebelei 

 was taken. At a higher elevation among the conifers growing on the 

 walls of the valley Aglaothorax sierranus was found, as well as the ever 

 present Trimerotropis fallax and Trimerotropis cceruleipes, and on the 

 steep upper ledges of bare rock near the upper part of the valley wall 

 Circotettix shastanus was discovered. 



El Portal, Mariposa County, California. Altitude, about 3,200 feet; 

 August 30. This is the terminus of the railroad in the gorge of the 

 Merced, near the entrance of the Yosemite National Park. At this 

 point the rather steep sides of the gorge are clothed with a heavy 

 forest of oaks and other deciduous trees mingled with some few conifers. 

 Few but interesting specimens were taken in the undergrowth, par- 

 ticularly Melanoplus ablutus and Cyrtophyllicus chlorum. A longer 

 stay would have proved very productive. 



Mill Valley, Marin County, California. Altitude, 300 feet; August 

 23. A few specimens of the genus Conocephalus were taken among 

 weeds growing in the street ditches. Just outside of the town on the
