One specimen each collected by Fullaway, 1911, and Hornbostel, August 1923. Five specimens, Usinger, and three specimens, Swezey, Ritidian Point, at the end of the road, June 30. These were found on a wide variety of plants, but eggs were discovered on only two kinds of plants, one of which was Pipturus . The eggs were found in batches of nine eggs each, arranged alternately in two parallel rows. They are creamy white with the chorion finely punctate, approximately 1 mm. in length and 0.50.mm. wide. The micropylar end is circular and subflattened with its surface feebly convex. A distinct, pale carina surrounds this apical plate. Along the middle of the egg is a broad, elevated ridge which is laterally impunctate and medially depressed and punctate. Upon hatching, the micropylar end opens as a hinged lid, the hinge being at the longitudinal ridge. A T-shaped egg burster is present. As development proceeds, red eye spots appear as is usual with hemipterous eggs. One batch of eggs collected at Ritidian Point, June 30, was parasitized by Ooencyrtus pacificus Waterston , as determined by D. T. Fullaway . Fourteen more specimens were taken by Swezey at Ritidian Point on August 6, 1936 , one at Orote Point, Sept. 27, one at Dandan, July 17, one at Machanao, June 4, and one on Ipomoea on Mt. Alifan , June 19 . I collected one on Mt. Alifan, May 26 and two on morning-glory at Machanao, June 4, 1936 .

This species had previously been reported from the Marianas Islands (Distant, Nova Caled., Zool. 1: 370, 1914).
