The name convergens refers to the close and converging antemedial and mid­median lines. Diagnosis. This new species is superficially similar to both D. divergens (Behr, 1870) and D. pulchra (Barnes & McDunnough, 1918) , but its forewing is more brownish than in D. divergens and the hindwing is bright yellow orange, not yellow as in D. divergens , but not as deep red as in D. pulchra . It differs from D. pulchra in the shape of the antemedial line ( Fig. 1 ), which is less curved than in D. pulchra and runs much closer to the median line, which is relatively straight. The valve is less pointed than in D. divergens but not as round as in D. pulchra ( Figs. 25 and 26 ). The everted vesica of this species is highly complex, as are the vesicas of related species of Drasteria ( Fig. 25 b and 26b). They tend to have numerous fingerlike processes, which are best viewed before mounting when the vesica can be inspected as a three­dimensional structure. Description. Antenna filiform in both sexes; eyes naked; palps and frons covered in pale brown hairs; patagium, tegula, and thorax covered in pale brown scales, patagium with a black longitudinal stripe; thorax covered in pale brown hairlike scales, venter paler than dorsum; legs concolorous with thorax; abdomen concolorous with thorax, venter paler than dorsum; forewing ground color pale brown; basal area brown; median field inner half cream colored, outer half pale brown; orbicular spot absent; reniform spot vaguely outlined in black, followed by large pale postreniform spot outlined in black, filled with white and pale brown, veins dark brown, lateral outline deeply serrate; claviform spot absent; basal line black double, thin; antemedial line black, double, enclosed area brown, two large bulges outward; median line consist of three closely spaced lines, two inner ones tan, outer one black that joins postmedial line under reniform spot; postmedial line black, outlining postreniform spot, deeply incurved under reniform spot; subterminal line cream colored with inward pointing black chevrons, outlined in tan; area beyond pale gray, darkening laterally; terminal line thin, gray; fringe pale tan with gray line; ventral side pale yellow; reniform spot dark, with dark shadow towards anal corner; subterminal line dark; terminal line dark; fringe dark along veins; hindwing bright yellow orange; discal spot dark brown to black; postmedial band dark brown to black, does not touch discal spot; terminal line dark, thin near anal corner where it meets postmedial band; ventral side pale yellow; discal spot dark; postmedial and terminal lines as on dorsal side; fringe dark (This makes no sense, fringe has no veins). Male genitalia ( Figs. 24 a and 24b): Valve length 4.4 mm , maximum width 1.3 mm , width at middle 0.5 mm ; medial fingerlike process 0.8 mm long and slender, right side digitus 0.35 mm , left side 0.15 mm ; aedeagus length 2.2 mm , width 0.6 mm , rounded; everted vesica length 2.3 mm , width 1.9 mm , round sack with numerous diverticula, some with small cornuti. Female genitalia ( Fig. 64 ): Ovipositor lobes 1.4 mm long, drawn to narrow point, small setae pointed forward; posterior apophyses 2.45 mm long, anterior apophyses 1.6 mm long; ductus bursae 2.0 mm long, sclerotized, slowly narrows from 1.0 mm to 0.55 mm at junction of corpus bursae; corpus bursae 4.3 x 3.3 mm , oval, signa absent; appendix bursae arises from left posterior corpus bursae, spirals down and forward, completing 2/3 revolution. Distribution and habitat. There are relatively few specimens of this species in collections. They were all collected in June–August in open dry coniferous forest habitats at high elevations in the Transverse Ranges and the southern Sierra Nevada.
