Diagnosis. Hypotrix diplogramma is unmistakable in appearance, but structurally it is closely related to H. ferricola and similar in size (forewing length: 13–15 mm). The subterminal line is a diffuse series of dark streaks, so the gray shading of the terminal area, so well defined in H. ferricola , bleeds into the subterminal area in H. diplogramma . Most of the forewing is cream colored with fine black streaks on and between the veins, and the dark shading intensifies toward the posterior margin of the wing, forming a

large black patch in some specimens. The male genitalia are similar to those of H. ferricola but in H. diplogramma the ventral margin of the valve proximal to the subapical notch is extended ventrally into a sharply angled process defining the anterior margin of the notch. In the vesica the basal spine is minute, but the subbasal cornuti are much larger than in H. ferricola . The female genitalia are also similar to those of H. ferricola , but the appendix bursae is shorter and more tightly coiled basally in H. diplogramma .

Distribution and biology. Hypotrix diplogramma occurs from eastern Arizona and southwestern New Mexico southward at least to Mexico City. Collection dates are from late March to late October, probably representing multiple generations. Most records are from ponderosa pine forests.
