found on Orange trees, where they were undoubtedly feeding 

 upon Psocids, for they were lurking about the nests of the 

 Psocids. 



Life History. 



The eggs (PI. XVI, fig. 5) are .6 mm. long, yellowish, with 

 a raised collar or crown at anterior end. laid flat on a leaf, singly, 

 in secluded place. Some were found under the web or nest of 

 Psocids on Orange leaves. A few laid in confinement hatched 

 in 4 to 5 days. The nymphs (PI. XVI, fig. 6) 'are reddish in 

 color and of very lively habits, though keeping secluded gener- 

 ally. I have not as yet bred any to maturity, but their nympbal 

 period is probably about the same as Triphlcps pcrscqncns, i. e., 

 14 days.

 ing on cane leaf-hoppers in the more elevated parts of sugar 

 plantations on Hawaii, especially where they were near forests, 

 as at Ola'a, Pahala, and Naalehu. They feed on larvae of Omiodcs 

 accept a, also.
