antemedial line oblique from costa to lower margin of 

 cell, thence vertical to inner margin, its upper half 

 obscure, indicated chiefly by a blackish outer border, 

 lower half distinct, whitish; the antemedial line pre- 

 ceded by a raised tuft of brown and blackish scales 

 which are bordered inwardly by a more or less con- 

 trasted white line; subterminal line faint, narrow, 

 slightly bulged at middle; discal dots black, separated, 

 distinct and rather large, especially the upper one; 

 terminal dots reduced, obscure and more or less conflu- 

 ent. Hiad wing light brown ; a thin blackish line along 

 termen; the veins not appreciably darkened. Alar 

 expanse, 19-20 mm. 



Male genitalia as given for the genus. Female geni- 

 talia with posterior half of ductus bursa very weakly 

 sclerotized. 



Type locality: "America septentrionalis" (type in 

 Paris Mus.). 



Food plant: Hickory {Carya alba) and wild azalea 

 (Ragonot records). Hickory and wahiut are the more 

 probable hosts. 



Distribution: United States: Connecticut, East 

 River (July). Canada: Nova Scotia, White Point 

 Beach (Queens County, July). 



244. Ortholepis pasadamia (Dyar), new combination 



FionBE 807 



Immyrla pasadamia Dyar, Ins. Insc. Menstr., vol. 5, p. 45, 

 1917.— McDunnough, Check liat, No. 6189, 1939. 



Maxillary palpus of male in the form of a short aig- 

 rette. 



Forewing uniformly dark glossy gray with a purplish 

 tint; the transverse lines well marked, narrow, whitish; a 

 contrasted white inner margin to the subbasal tuft; dis- 

 cal dots usually confluent, distinguishable but not 

 strongly contrasted against the dark ground color. 

 Hind wing smoky fuscous; the veins faintly darkened. 

 Alar expanse, 17-20 mm. 



Male genitaUa as in jugosella. Female genitalia as in 

 jugosella except ductus bursae sclerotized along ventral 

 surface to genital opening. 



Type locality: St. Johns, Quebec (type in USNM). 



Food plant: Betula. 



Distribution: United States: Pennsylvania, Ha- 

 zleton (June); New Hampshire, Dublin, Hampton 

 (July) ; Maine, Mount Desert Island (July) , Sebec Lake 

 (July); Washington, Meadow Creek (Grant County, 

 Apr.), reared specimen, Walla Walla (June). Canada: 

 Ontario, Blacotasing (July), Ottawa (July), Waubamia 

 (Perry Sound, July) ; Quebec, St. Johns (June) . 



The foregoing description was drawn from typical 

 examples represented in the National Collection by a 

 series of 16 males and females. There are also before 

 me four specimens from Maine, New Hampshire, and 

 Quebec of what appears to be a color form in which the 

 transverse lines (except for the white inner border of the 

 raised-scale patch) are almost completely obliterated; 

 the ground color of the forewing is darker (more pur- 

 plish) and the hind wing is brown (as in jugosella) ; there 



is also a faint narrow dusting of whitish scales in the 

 median area of forewing. The genitalia of these speci- 

 mens are identical with those of typical pasadamia. 

 Examples of both forms have been reared from Betvla.

 and femora a mixture of scales and hairs.]

Tongue weU developed. Antenna of male ciliate- 

 pubescent (the cilia a trifle shorter than width of seg- 

 ments) the shaft curved towards base and containing 

 two or three short teeth in the incurvation; of female 

 simple. Labial palpus obliquely ascending, not reach- 

 ing height of vertex; third segment short, less than one- 

 third of second. MaxUlary palpus minute, filiform. 

 Forewing smooth; 11 veins; vein 2 from before but near 

 lower outer angle of cell; 3 from the angle; 4 and 5 

 separated at base; 6 from below upper angle of cell, 

 straight; 8 and 9 stalked for over half their lengths; 10 

 from the cell, shortly separated from the stalk of 8-9 at 

 base; male without costal fold. Hind wing with vein 2 

 from well before outer angle of cell; 3 from the angle; 4 

 and 5 anastomosed for about half their lengths beyond 

 cell; 7 and 8 closely approximate for a short distance 

 beyond ceU; cell less than half the length of wing; dis- 

 cocellular vein curved, produced at lower angle. Eighth 

 abdominal segment of male with pair of ventrolateral 

 hair tufts. 



Vestiture of head, thorax, labial palpi, femora, and 

 and foretibiae a mixture of scales and hairs. 



Male genitalia with uncus about as broad as long; at 

 apical margin broadly rounded. Apical process of 

 gnathos (from ventral view) an inverted heart-shaped 

 lobe terminating in a short, slender, hooked spine. 

 Transtifla absent. Harpe short, stubby; its apex bluntly 

 rounded; costa broadly and strongly sclerotized through- 

 out, but not produced at apex; otherwise simple. Anel- 

 lus a U-shaped plate terminating in short lateral lobes. 

 Aedeagus slender; penis armed with moderately stout, 

 elongate cornutus or two similar cornuti. Vinculum 

 stout, slightly longer than greatest width; tapering to 

 blunt and rather broad terminal margin. 



Female genitalia without signum; bursa copulatrix 

 small and with a rather broad, fused cartilagenouslike 

 thickening around its lateral and anterior margins, 

 otherwise minutely granulate and containing a weak 

 elongate chitinized strip ; ductus bursae twice as long as 

 bursa, flattened, its ventral surface sclerotized and gran- 

 ulate through its length, the sclerotization extending 

 into bursa; genital opening simple. Eighth-segment
