 Mt. Whitney, at an elevation of 11,000 feet. 



Stenus. — >Si. renifer, S. incultus and S. gilw occur on 

 the Colorado River, the two latter being moderately com-

 are very abundant along mountain streams, the former 

 also occurring occasionally in the valleys: costalis, less 

 common in same situations: terricola, one example, San

 everywhere in the lower country, the former common 

 at times, the latter always abundant: insignis, not rare at 

 Pomona, November to May: vestalis, one example, 

 Riverside: sayi, found in some numbers about the roots 

 of grass in marshy spot near Pomona, January; not 

 seen elsewhere: pinguis, common in many localities, 

 occurring in prodigious numbers at times; hundreds 

 have been found on every square yard of ground about 

 a small lake near Pasadena, great numbers flying about 

 and swarming on the shrubbery about the lake at the 

 same time: Icehdus, rather rare, Ventura, Riverside, 

 Pomona; March to May: alveolatus, one example, so
