uous on the middle third of tegulae, throwing into con- 

 trast their dark basal and even darker apical areas. 

 Forewing ashy white with brownish areas forming a 

 rather strongly contrasted pattern; basal area brownish 

 fuscous with a narrow pale subbasal border; antemedial 

 line well marked, somewhat sinuate and slanting out- 

 ward from costa to inner margin, white, with a narrow 

 dark inner border and a broad darker outer border 

 which is appreciably broadened towards inner margin; 

 discal dots fused into a large, dark spot at end of ceU; 

 subterminal line slightly sinuate (outwardly angled be- 

 tween veins 1 and 5), white, rather broadly bordered 

 inwardly and outwardly by dark brownish fuscous; 

 terminal area of the pale ground color with terminal 

 margiQ dark brown; cilia pale brownish fuscous. Hind 

 wing pale fuscous with a dark line along termen; cilia 

 whitish. Alar expanse, 14-16 mm. 



Male genitaha with apical process of gnathos partially 

 fused, large, the lobes flaring but not so broadly so as 

 those of zamacrella, the posterior projections sharp and 

 appreciably separated; penis with several long sclero- 

 tized folds but without cornuti (similar to that of 

 zamacrella) . 



Female genitalia with a pair of strongly sclerotized 

 plates in ductus bursae at genital opening; ventral 

 plate at opening large; signum a small plate with from 

 two to four bladelike projections; bm-sa copulatrix 

 smooth except for a few minute scobinations surround- 

 ing signum. 



Type locality: RockviUe, Pa. (type in USNM). 



Food : Scales on pine. 



DisTBiBtjTiON : Pennsylvania, RockviUe (May) ; North 

 Carolina, Tryon, Southern Pines (Sept.). 



Twelve specimens examined. 



This species is apparently confined to the Eastern 

 States. It is readily separable on habitus and structure 

 from the western zamacrella but is obviously closely 

 related to that species.

Ashy fuscous, resembling myersella very closely in 

 color and markings but with the transverse pale lines 

 and dark areas of forewing less strongly contrasted; 

 antemedial and subterminal lines faint but distinguish- 

 able and otherwise as on myersella, their dark borders 

 a paler brown, not so broad and more obscm-ed than 

 those on myersella. Hind wing translucent, with a very 

 pale ocherous tint; termen hardly darker; cilia con- 

 colorous. Alar expanse, 17-20 mm. 



Male genitalia with apical process of gnathos partially 



fused, large, the lobes flaring and similar to those of 

 myersella, the posterior projections short, blunt and 

 close together as in zamacrella. Uncus narrower than 

 that of either myersella or zamacrella. 



Type localities: Arizona {ephestiella, in Paris Mus.) ; 

 Williams, Ariz. (June; lustrella, in USNM). 



Food : Unknown, presumably scales. 



Disteibution: Arizona. 



This species is known to me only from Dyar's male 

 type. I have no reason to question the synonymy 

 which he proposed in 1905. The three species, zama- 

 crella, myersella, and ephestiella, can readily be separated 

 on color and genitalic characters but they are obviously 

 very closely related and form a distinct subgroup within 

 the genus.

Similar in color and markings to myersella except that 

 central area of forewing (between antemedial and sub- 

 terminal liaes) is much darker, blackish brown; the basal 

 area is paler than the median area, but the entire wing 

 lacks the dusting of white so characteristic of myersella; 

 antemedial white line outwardly angulate at middle; 

 discal dot as in myersella, but sometimes obscured by 

 the general dark suffusion. Hind wing dark smoky- 

 fuscous; cilia slightly paler. Alar expanse, 16-20 mm. 



Male genitalia of the Baphala type; uncus with lateral 

 edges concave; apical process of gnathos consisting of a 

 pair of tear-shaped lobes fused at apex; vinculum long; 

 penis smooth. Female genitalia with pair of sclerotized 

 plates in ductus bursae at genital opening; ventral plate 

 at genital opening large; ductus bursae long and much 

 more slender than in myersella; signum a small plate 

 armed with several irregularly shaped, thornlike projec- 

 tions; bursa copulatrix triangulate, smooth except for a 

 few minute scobinations surrounding signum. 



Type locality: Tryon, N. C. (type in USNM). 



Food: Unknown, presumably scale insects. 



Known to me only from the type series, two males 

 and three females from the type locality (not one male 

 and four females as stated by Dyar). The species is a 

 transition one linking typical Laetilia and Baphala; it 

 has Baphala genitalia but lacks the other diagnostic 

 characters of that genus, the eighth abdominal segment 

 of the male being simple, the male antenna without 

 sinus or sex-scaHng on the base of shaft, and veins 3 and 

 5 of hind wing strongly stalked.

Clay colored, with extreme base of forewing blackish; 

 antemedial line slanting outwardly to inner margin and 

 with a slight notch at vein lb, distinct and blackish; 

 subterminal line faint, narrow, subdenticulate, blackish, 

 bordered outwardly by a somewhat wider pale band;
