AMERICAN MOTHS OF THE SUBFAMILY PHYCITtNAE 



209 



scaled, reaching to vertex in male, to slightly above in 

 female; third segment about half the length of second, 

 acuminate. Maxillary palpus squamous. Forewing 

 smooth; 11 veins; vein 2 from before lower outer angle 

 of cell; 3 from the angle; 4 and 5 connate (or very 

 shortly stalked), separated from 3 at base; 6 from 

 below upper angle of ceU, straight; 8 and 9 stalked; 

 10 from cell, separated from stalk of 8-9; male without 

 costal fold. Hind wing with vein 2 from before (but 

 near) lower outer angle of cell; 3 and 5 stalked; 7 and 

 8 anastomosed for half their lengths beyond cell; cell 

 about half the length of wing, partially open; dis- 

 cocellular vein incomplete. Eighth abdominal segment 

 of male with two pairs of ventrolateral hair tufts. 



Male genitalia with apical process of gnathos a stout 

 hook. Uncus triangulate. Transtilla incomplete, ele- 

 ments minute. Harpe elongate, narrow, not appre- 

 ciably tapering; apex rounded; strongly sclerotized 

 costa projecting at apex into a short, sharp spine; 

 clasper erect, short, weakly sclerotized. Anellus a 

 curved U-shaped plate with broad base. Aedeagus 

 short, stout, nearly straight; penis armed with a single, 

 long, moderately slender cornutus (nearly as long as 

 aedeagus). Vinculiun stout, about as broad as long, 

 slightly tapering to truncate terminal margin. 



Female genitalia with bursa copulatrix scobinate 

 over most of its inner surface; signum developed as an 

 irregularly shaped spined plate near junction of ductus 

 bursae; ductus bursae shorter than bursa, with a pair 

 of narrow, sclerotized, strongly spined plates along the 

 lateral margins, some minute scobinations in the inter- 

 vening area, a fingerlike, ventral, sclerotized plate from 

 genital opening, and a few granulations on the inner 

 wall above genital opening; ductus seminaUs from 

 bursa near its junction with ductus bursae. 



A distinct genus with one North American species; 

 easily distinguished by venation and genitalia.

Forewing glossy brownish fuscous (purplish brown 

 in some lights) ; antemedial line grayish white, straight, 

 shghtly cm-ved or weakly angled at cell, slanting a trifle 

 from costa to inner margin, of varying width depending 

 on the amount of white scaling and sometimes (but 

 rarely) partially divided by a fine median dark line; 

 subterminal line obscure or indistinguishable, fine, 

 whitish, nearly vertical from costa to tornus, very 



faintly bordered by blackish lines; on costa adjacent to 

 inner border of the subterminal line a more or less 

 extended and triangulate grayish white patch; blackish 

 discal and terminal dots obscure, the discal dots more 

 or less confluent. Hind wings smoky fuscous, glossy. 

 Alar expanse, 13-14 mm. 



Genitalia as given for the genus; terminal margin of 

 vinculum broadly and shallowly notched. 



Type localities: Illinois (hammondi, in USNM); 

 Iowa (angulella, in USNM) . 



Food plants: Apple, pear, Prunus maritima. 

 (Specimens in USNM also labeled "from sycamore" 

 and "from acorns," but these are very dubious records.) 

 The larva is a leaf skeletonizer. 



Distribution: Connecticut, East River (Aug.) ; Rhode 

 Island, Weekapaug (Aug., Sept.); Ohio, Cincinnati 

 (Aug.) ; Indiana, Bedford (July) ; Illinois, Oconee (July, 

 Aug.); Iowa; Kansas, Wathena (July), Wichita (June); 

 Missouri, several specimens with no further locality, 

 St. Louis (Aug.). Rather generally distributed 

 throughout the eastern and central United States and 

 Canada. 



Worn females of this species are superficially similar 

 to small specimens of Moodna ostrinella (Clemens) and 

 the two species have been occasionally confused. They 

 are quite distinct, however, on both venation and 

 genitalia. The character on which Dyar separated his 

 angulella (its "strongly angled" antemedial line) is 

 rather imaginary than real. The pale markings on the 

 forewing of hammondi are formed by rather thinly 

 spread, whitish scales and vary from specimen to 

 specimen in size, shape, and intensity. Dyar's type is 

 rubbed, a condition which accounts in part for the 

 angulate condition of the antemedial line, a very slight 

 angulation at that. Its genitalia agree in every detail 

 with those of typical hammondi. 



116. Patriciola, new genus 



Type of genus: Patriciola semicana, new species. 



Tongue well developed. Antennae simple in both 

 sexes, shortly pubescent. Labial palpus porrect (beak- 

 like), long, projecting about four times the length of 

 head beyond it; ahke in both sexes. Maxillary palpus 

 squamous, large ; alike in both sexes. Forewing smooth; 

 11 veins; vein 2 from well before the lower outer angle 

 of the cell; vein 3 remote from 2 but before the angle of 

 the cell; 4 from the angle approximate to 5 for some 

 distance from cell; 6 from below upper angle of cell, 

 straight; 8 and 9 stalked; 10 connate or very shortly 

 stalked with 8-9; male without costal fold. Hind wing 

 with vein 2 from well before the lower outer angle of the 

 cell; 3 from near but before the angle; 5 from the angle; 

 7 and 8 contiguous (touching but not completely fused) 

 for nearly half their lengths beyond cell ; cell about half 

 the length of the wing; discoceUular vein curved. 

 Eighth abdominal segment of male simple. 



Male genitalia with apical process of gnathos a rather 

 broadly based, blunt hook produced anteriorly into 

 a long, flat, sclerotized apron (the whole process resem-
