Froeschner Department of Entomology, Smithsonian Institution, Washington, D.C. 20560. Abstract. — Elsiella, a new genus for the "lost" Ecuadorian species Ebora plana Walker, 1867, belongs among those genera of the tribe Pentatomini characterized by the specialized elevations on the midline of the pro-, meso-, and metastema. Its siblingship appears to lie with the genus Serdia Stal. The Ecuadorian species Ebora plana was described by Walker (1867: 416-417), along with three Australian species, in his new genus Ebora. Commenting upon this species he wrote, "This species may be the type of a distinct genus." Much later Kirkaldy (1909: XXXII) selected the Austra-lian species Ebora circumdata Walker as the type-species of Ebora and then (1909: 186) placed that genus in synonymy under the genus Notius Dallas (1851: 155) in the tribe Halyini; he placed the species Ebora plana in his Hst of "Pentatominae of uncertain position," a status which it has retained. Now, through the kind and persistent searching of the collection of the British Museum (Natural History) by Dr. W. R. Dolling, Walker's type-specimen has been located. That specimen is in reasonable study condition but the pin broke the scutellum, dislocated the pronotum, and in passing out of the insect's body exploded the metastemal elevation; in addition, dermestids damaged the dorsum of the abdomen and destroyed all the mem-brane on one wing and the base of the other membrane. Fortunately at least one of each appendage is present. Thus it was possible for my wife, Elsie Herbold Froeschner, to reconstruct nearly the entire dorsal aspect of the holotype (except the base of the membranes) in her drawing (Fig. 1). The original locality label bearing the word "Archidona" is still present. Because the holotype appears so very brittle and has had the abdomen cleaned out by dermestids I made no attempt to dissect it. Unfortunately the original description omitted mention of most of the important structural characters and thus prevented subsequent generic
