Type material. Holotype ♁. Arizona, Cochise Co. AMNH, examined.

Other material examined and distribution. Mexico: State of Durango (Sierra Madre Occidental). USA: Arizona: Cochise Co. (Chiricahua Mts), Graham Co. (Pinaleno Mts), Pima Co. (Santa Catalina Mts), and Santa Cruz Co. (Santa Rita Mts). New Mexico: Grant Co.

Diagnosis. Within United States the boldly streaked orange and blackish-gray forewing pattern of Hypotrix ferricola is unmistakable. Hypotrix ferricola is closely related to H. aselenographa (Dyar, 1916), comb. n. [Trichorthosia aselenographa Dyar, 1916] from Mexico, except the subterminal line in H. ferricola is parallel to the wing margin in the middle part of the wing and then curves outward near the forewing apex (the subterminal line is almost straight to the forewing apex in H. aselenographa, so the terminal area is broad mesially and tapered toward each end), and the dark patch in the cell through the reniform and orbicular spots is paler, so the orbicular spot is evident as a dark streak and the reniform spot as a dark crescent (the streak in the cell in H. aselenographa is black, completely obscuring the reniform and orbicular spots). The forewing length in H. ferricola is 13 to 15 mm. The male genitalia of H. ferricola have a small, triangular, heavily sclerotized cucullus with a stout seta at the anal angle, a rounded U-shaped notch in the ventral margin of the valve anterior to the cucullus, an apically spatulate uncus, and a long, slender digitus. Th e vesica is very long and narrow with a dense band of spinules on the apical half, a stout rose-thorn spine at the base, and a field of six or seven spike-like cornuti subbasally. In the female genitalia the corpus bursae is rounded and the appendix bursae is long and narrow and gently coiled.

Distribution and biology. Hypotrix ferricola occurs in southeastern Arizona, southwestern New Mexico, and northern Mexico. Collecting dates range from early April to early August, possibly representing several generations. Most records are from ponderosa pine forests.
