 nia." I have seen specimens taken at Stewart's Point

 bark at Lake Tahoe; found also by Mr. Daggett, on 

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



Stenus. 8. renifer, S. incultus and 8. gilw occur on 

 the Colorado River, the two latter being moderately com- 

 mon in Yuma early in July: sculptilis and californicus 

 are very abundant along mountain streams, the former 

 also occurring occasionally in the valleys: costalis, less 

 common in same situations: terricola, one example, San 

 Bernardino Mountains: znnicus and pacificus are found 

 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: Icetulus, rather rare, Ventura, Riverside, 

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

 named, San Diego: lucidus, a single example taken at

 the middle regions; corvus from Fort Tejon; dives and 

 subgriseus from the north; ellipticus, colonus, villosus, 

 exilis, and pollens from " California " without definite
