Zarhipis. I have seen one example of integripen- 

 nis from Palm Springs (April 10), and one taken at 

 light, at Pasadena, April 14; this and ruficollis, piciven- 

 tris, and riversi are all taken about San Francisco; but 

 it is very doubtful if we have as many species as names. 



Mastinocerus. One example taken at light, at River- 

 side, June 7, is referred to opacus. 



Cenophengis. C. debilis has been found at Los An- 

 geles and at Pasadena (July); it is very rare. 



Podabrus. P. comes is a rather common species in 

 the southern sierras and in the foot-hills near Pomona 

 and Pasadena. An apparently undescribed species is 

 not rare at Pasadena in May, occurring usually on wil- 

 lows. P. latimanus and P. tomentosus are both recorded 

 from "Gal.," but it is not likely that they will be found 

 with us as the genus is as a rule northern in distribu- 

 tion: binotatus is said to occur at San Mateo: xantho- 

 derus, Lake Tahoe: macer, San Mateo and Sylvania: 

 tejonicus, Tejon: bolter i, Lake Tahoe: mdlitu8,8ylv&m&, 

 Geysers, and Lake Tahoe: cavicollis, San Francisco to 

 Lake Tahoe: corners is described from "Cal." without 

 mention of exact locality. P. lutosus is the female of 

 cavicollis. There are several undescribed species in my 

 collection. 



Silis. S. cava occurs not rarely in the foot-hills and 

 mountains near Pomona: filigera is scarce; I have 

 found it at Riverside in early spring: flavida occurs at 

 Lake Tahoe: lutea is found about San Francisco. 



Telephorus. T. consors is very abundant at Pomona, 

 Riverside, Pasadena, etc., flying in the early evenings of 

 April and May, and often coming to light. A form which 

 is with some doubt referred to notatus is not rare at
