PROC. ENTOMOL. SOC. WASH. 85(1), 1983, pp. 174-176 A NEW SPECIES OF GLOANNA NYE (LEPIDOPTERA: NOCTUIDAE) FROM WEST TEXAS Andre Blanchard and Edward C. Knudson (AB) 3023 Underwood, Houston, Texas 77025; (ECK) 804 Woodstock, Bellaire, Texas 77401. Abstract. — Gloanna hecate is described. Imagines and male and female genitalia are figured. While collecting the Sierra Diablo mountains of western Texas in 1969, the senior author took a small series of a noctuid which later proved to be an unde-scribed species of Gloanna Nye. Seeking to improve on the series, the junior author visited the same locality 1 3 years later and succeeded in obtaining three additional specimens. The Sierra Diablo lie about 30 miles due south of the Guadaloupe Mountains, rising to just over 6600 feet. The western slopes are gentle, but the eastern slopes drop precipitously nearly 3000 feet to the desert floor below. The upper elevations support an open forest of the pinyon pine, juniper, and several species of oak. The area remained virtually uncollected until investigations by the senior author began in the late 1960's, and it has yielded a number of previously unknown Lepidoptera.
