47. Melittobia hawaiiensis Perkins,
Haw. Ent. Soc., Proc. 1: 124, 1907.
Piti, May 20, Swezey; Piti, Sept. 27, reared from pupae found Sept. 24 in a cocoon of Pison argentatum . On another occasion there were six cocoons of Pison argentatum in cells of a mud nest, and each cocoon had exit holes where Melittobia had issued, which shows the prevalence of this wasp parasite. Three slide mounts, two retained in U. S. National Museum; one specimen mounted on a point.
