 to Sept. 30 (Wbittier, Calif.). Specimens collected in Riverside, 

 Calif., as early as June 8 (9) and as late as September 4 (d^) indicate 

 that pallidipennis may have, at least ha that area, a rather continuous 

 generation, or at least a longer flight period than is known for most 

 species of Ogcodes. 



Recorded hosts: Pardosa saxatilis (Hentz) and a Lycosa species 

 were recorded by Kaston (1937) from Connecticut (see also table 1). 



New host records: Ten specimens were reared by the author from 

 the following spiders collected in Los Angeles County, Cahf., during 

 the years 1943-1950: 



Steatoda palomara Chamberlin and Ivie, immature, collected at Glendale. 

 Parasite ( 9 ) emerged as an adult Sept. 7, 1943. 



Walmus species, immature, collected at Fish Canyon, San Gabriel Mts. 

 Parasite (d') emerged from host June 11, 1944, pupated June 13, emerged as 

 adult June 21, and died July 3, 1944. 



Xysticus montanensis Keyserling, immature, collected at Glendale. Parasite 

 ( 9 ) emerged from host Aug. 11, 1946, pupated Aug. 13, emerged as adult Aug. 24,
