It was asso- ciated with Diabrotica 13-punctata and D. picticornis. June 15, 1907, Mr. C. S. Spooner, while working under the writer's direction at San Antonio, Tex., found numerous beetles of this species on squash, where it was associated with D. incticornis. It was also noticed on cotton. During 1908, Mr. D. K. McMillan, of this Bureau, observed this beetle during March on eggplant at Olmito, Tex., eating melon.
