April 10, 1908. — Collected many brown and a few green Jassids in 

 wheat stubble and volunteer wheat, by sweeping. Found eggs in 

 masses of 2 to 5 in net, and found that they came from areas where 

 only stubble was, as well as other areas. Examining stubble found 

 eggs tucked under edge of sheath, often indicated externally by slight 

 lifting of the edge, sometimes showing ends of eggs which lie side by 

 side perpendicular to edge of sheath, lightly stuck together and slightly 

 or not at all adhering to sheath. Usually 4 to 10 in one straw, some- 

 times more, always above topmost node of stubble. Eggs pale red 

 and green opalescent, club shaped with sort of pedestal at edge nearest 

 edge of sheath. Collected eggs and stems to rear and photograph. 



Sept. 13, 1909. — Collected Jassid eggs in wheat stubble, in third field 

 north of Mr. Priest's orchard on Military Hill. There are two kinds 

 of eggs, one the same as those studied and photographed April 10, 

 1908, the other brown, with no distinct micropylar armature, placed 

 similarly to the former but less regularly. Rear and describe. Swept 

 2 adults from the same spot. The eggs were collected not on the 

 stubble itself but on green and partly green second growth shoots. 



Sept. 14. — Observed two insects within eggs collected Sept. 13 cutting 

 round holes like some that were observed in the eggs when they were 

 collected; time, 10:23 a.m. Issuance from egg completed, 11:12 a.m. 

 This parasite was determined by Crawford as the trichogrammid Oli- 

 gosiia sp. 



Oligosita sp. : General color pale green ; abdomen pale yellow ; 

 ocelli and eyes reddish-brown ; stigmata dark brown ; antennte, legs,
