Discussion. The Florida specimens are similar to the lectotype, slightly more yellow, although that could be attributed to fading of the type specimen. The species is smaller than the type of the genus, E. geometridalis Amsel, 1956 of Venezuela, and the outer edge of the brown basal area of the forewing is transverse rather than oblique. We transfer Ennomosia Amsel, 1956 to Glaphyriinae based on the following characters. Males of both species possess a costal retinacular hook. The tympanic bullae are round, and the fornix tympani protrudes over the venula prima ( Fig. 5E ). The male valvae are broad and simple (narrower in E. basalis , Fig. 4A ), and the tegumen is elongate. In the female of E. basalis , the ductus seminalis is wide and emerges from the lateral wall of the corpus bursae. The maculation unmistakably resembles that of many glaphyriines. It shares genitalic characters with Chilozela Munroe, 1964 , Eupoca Warren, 1891 , and Macreupoca Munroe, 1964 : broad valvae, a simple juxta without processes, and a membranous corpus bursae without abundant sclerotization ( Munroe 1964). However, the falcate forewing more resembles that of Scybalistodes Munroe, 1964 . The position of the genus in Glaphyriinae remains unclear.
