Diagnosis: The new species is similar externalty to E. Dili recita sWARREN l9l β); but is larger in si Ze. the forewing ground colour is darker brown withochreotis irroration along the costa. the basal area is broader. the antemediat line is Sinu OUS, arcuate, nono Of the ten known specimens have strong, strat glit, blackishantemediat line. The orbicular stigma of E. Peregovit Si is not a fine, dark commabui an oblique-elliptical spol. filled osten with blackisti scales. the reniform is as mali lunule with whitish-ochreous ouiline, a rounded clavi forin stigma with whit-ish-ochi eous annulus and blackish centre is alwayS present, this marking is regu larly absent frona E. Dilineala. A smaller part of the specimens have a broad blackish brown or blackisti grey fascia running frona the base of the wing along the subcellular vein to the subterminal line, covering also the lower paris of the celi then fused with the dark apical part of the subterminal line, forming a clark Zone frona the base of the wing to the apeX. The unique feature of the male genitalia of E. Perego vitai is the bifid uncus ali other EPOSestis species have single unctis. The other paris of the genitalia showalso distinctive features compared with tho se of E. Dilineata af the socii are longer stra ight. the fultura superior is larger with strong laterat foliis, the valva is morero unded, the sacculus is narrower and the cornuti field of the vesica consists of longer Cornuti.
The fe male genitalia of the new species have also a unique character, the two scieroti Zed plates of the proximal part of the corpus bursae near the tubular distat part os corpus bursae. The other paris of the organ are most similar to tho se of E. Dili recita, but the signum is significantly large r. Stronger the ventral plate of the penultimate segment is larger. rounded quadrangular, the ostium bursae is withstronger laterat scieroti Zation and the ductus bursae is bro ader.
