Plantation (Timberlakc) ; Mani, Kipahnlu (Swezey) ; Ha- 

 waii, Pahala (Swezey). 



Bred from Tephriiis crassipes breeding in the heads of 

 Bidrns by the late F. W. Terry, Honolnln, Jan. lOOC, by 

 P. H. Timberlake, Honolnln, Jnly 1918, and by J. C. Brid- 

 well, Wailnkn, Mani, Ang. 1918. 



This species is an immigrant, doubtless arriving with its 

 host, from what conntry we can only conjectnre. The habits 

 of the species were .stndied by Mr. Terry in Jan. 1900. and 

 Mr. Swezey's material from Mani was taken the same year. 

 This is donbtless the Bracon recorded by Dr. Perkins in the 

 introdnction of the Fanna Hawaiiensis as attacking Tepliritis.
