D. C. Hawks; holotype 15 June 1987, allotype 22 June 1987. <b>Paratypes</b> (25 ♁ 53 &amp;female;): 23 ♁ 46 &amp;female; from the type locality, various dates and collectors. Remaining paratypes: Kern County: 10 km NW of Frazier Park (1 &amp;female;); Los Angeles County: San Gabriel Mountains, 4 km SSW of Valyermo (1 ♁ 4 &amp;female;); Juniper Hills, 3 km S of Pearblossom (1 &amp;female;); San Gabriel Mountains, Ridge Route, Halfway House (l ♁); San Diego County: 6 km S of Oak Grove (1 &amp;female;). Holotype and allotype deposited at PMNH, paratypes deposited at LACM and other USA museums as well as in private collections. <b>Diagnosis.</b> The forewings of <i>C</i>. <i>c</i>. <i>occidentalis</i> are similar to those of other subspecies. Distinguishing hindwing characters include: dorsal surface has many black scales at the base; wider inner band; narrower postmedial band; yellowish color of the dorsal surface consistently darker. About 5 percent of the specimens of <i>C</i>. <i>c</i>. <i>occidentalis</i> examined could be confused with specimens of the nominate subspecies. <b>Description.</b> <i>Forewing</i>: dorsal surface ground color charcoal to brownish gray, mottled with hoary scales; antemedial and postmedial lines black, modestly apparent; subreniform whitish to yellow, usually visible. <i>Hindwing</i>: pale areas dull yellow orange; bands black, apical spot dull yellow orange; anal spot separated from outer band; conspicuously narrow postmedial band (usually only 1–2 mm near vein M2); anterior half of outer band wide with conspicuous rounded indentation in inner edge of outer band between M2 and Cu1; many dark scales at base. <b>Distribution and biology.</b> <i>Catocala c</i>. <i>occidentalis</i> occurs along the western desert edge in southern California and northward to at least Trinity County. County records for USA are as follows. CALIFORNIA: Kern, Lake, Los Angeles, Madera, Napa, Riverside, San Bernardino, San Diego, Santa Clara, Solano, Trinity.. The immature stages of <i>C</i>. <i>c</i>. <i>occidentalis</i> have been described and the larva figured by Johnson (1985). At the San Diego, Riverside, and San Bernardino County localities the larvae feed on <i>Quercus cornelius-mulleri</i>. Adults have been collected from early June to late August, with the peak flight period in late June at Pinyon Flat.
