Conacontia orba Smith, 1903, Trans. Amer. Ent. Soc., 29:210.    NEW SYNONYMY

Diagnosis: Therasea huachuca is sexually dimorphic. The male has the upper two thirds of the forewing a light yellow-white. The lower third is brown, but is commonly constricted in the middle by a deep indetation of the dorsal light region. The deepness of the constriction, however, is variable. Streaks from the costa, if present, are weak, yellow green, and indistinct. There is extensively blue scaling near the apex of the forewing. The subterminal area has a large yellow-white region.

The female has the upper one-half yellow-white. There are two strong brown bars descending from the costa. The first part reaches the anterior portion of the orbicular and the second extends behind the reniform. The orbicular is a large, ovate, black spot.

Wing expanse from base to apex in one selected individual 12 mm.
