description: <i>Bryolymnia semifascia</i> (Smith, 1900) Figs 20–22, 32, 40 <i>Chytonix semifascia</i> Smith 1900: 415. <b>Type material.</b> <b>Lectotype</b> ♁. USNM, examined. Designated by Todd (1982). Type locality: USA, Colorado, Garfield Co. <b>Other material examined and distribution.</b> <b>USA:</b> Arizona: Cochise Co. (Huachuca Mts), Graham Co. (Pinaleno Mts), Pima Co. (Santa Catalina Mts), Santa Cruz Co. (Atascosa, Patagonia, and Santa Rita Mts), and Yavapai Co.; Colorado: Grand Co. and Garfield Co. New Mexico: Los Alamos Co., and Socorro Co.; Utah: San Juan Co. <b>Diagnosis.</b> <i>Bryolymnia semifascia</i> can be recognized by the brown forewing with blackish-brown shading and streaks, especially toward the hind margin of the wing, and usually with a contrasting white patch in the lower part of the medial area. The white patch, the best character to recognize this species, may consist of only a few scattered white scales, but in most specimens it covers most, sometimes all, of the lower half of the medial area. In many specimens light-gray scales form partial highlights to the otherwise obscure reniform and orbicular spots, and the postmedial and subterminal lines. Forewing length ranges from 11 to 14 mm. Th e hindwing is pale fuscous with darker fuscous on the veins, discal spot, postmedial line and wing margin with that of the female only slightly darker than in the male. <b>Male genitalia.</b> These are most similar to those of <i>Bryolymnia anthracitaria</i>. As in <i>B</i>. <i>anthracitaria</i> the dorsal surface of the clasper is serrated, the clasper is without a subbasal process, and the digitus is large and heavily sclerotized. The main differences from the genitalia of <i>B</i>. <i>anthracitaria</i> are that the dorsal surface of the digitus is densely hairy, the clasper in much smaller, and the vesica has only a single slender tapered cornutus. <b>Female genitalia.</b> The corpus bursae is rounded, about 0.6 × as long as the heavily sclerotized, parallel-sided ductus bursae, and gives rise to a rounded lightly sclerotized appendix bursae ventrally at the junction with the ductus bursae. The sclerotized plate in the ostium bursae has a wide V-shaped notch on the posterior margin. <b>Distribution and biology.</b> <i>Bryolymnia semifascia</i> occurs from northern Colorado and southern Utah southward to southeastern Arizona and south-central New Mexico. Adults have been collected from mid-June to mid-September in conifer forests.
