414 PROCEEDINGS OP THE ACADEMY OF [Oct., 



grassy slopes, which ascend farther back to Mt. Tamalpais, several very 

 interesting species of Melanoplus were found among numerous more 

 common Orthoptera. The region was dry and dusty and much like 

 the other low dry grass-covered hills of the coast. 



Mt. Tamalpais, Marin County, California. Altitude, 1,500-2,500 

 feet; August 23. On the summit but little Orthoptera was to be 

 found among the manzanita and other low shrubbery. A fog con- 

 tinually driving across the mountain top during my stay no doubt 

 prevented a larger number being taken. Near the upper level of 

 the timber a colony of Neduba was found in a grassy ravine with 

 a scattered growth of pines, oaks and other trees. From this point 

 downward, collecting among the grasses and herbs beside the rail- 

 road track was rather productive, but the mountain ridges covered with 

 manzanita bushes and low herbs revealed Orthoptera in numbers, 

 among which were some very interesting species. The slopes were 

 usually steep, and collecting seemed both more convenient and more 

 productive on the ridges and occasional small level spots. Just below 

 the central portion of this manzanita-covered zone proved the most 

 productive altitude. 



The material collected by Dr. Joseph Grinnell was all taken during 

 a biological survey of the San Bernardino Mountains, 2 the greater 

 proportion of the specimens being taken on the South Fork of the 

 Santa Ana River. The specimens given by Mr. Fordyce Grinnell, Jr., 

 were secured at several localities in the San Jacinto Mountains, 

 and their eastern spur the Santa Rosa Mountains, on Mt. Wilson, San 

 Gabriel Mountains and at Pasadena. The material from the San 

 Bernardino, San Jacinto and Santa Rosa ranges was of exceptional 

 interest, as little or nothing was known of them orthopterologically. 

 The latter is also true of the material taken by Hebard in the Bird 

 Spring Mountains, at Cima, in the North Range of the Providence 

 Mountains and at Las Vegas, Nevada. 



FORFICULID^E. 



Anisolabis annulipes (H. Lucas). 



Three males of this species were taken at Coronado Beach, August 15, 

 from under marigolds in a garden. 



Caudell has recorded this species from California.
