downward, but when flattened out it shows an appre- 

 ciable constriction at middle. Anellus a simple shield- 

 shaped plate. Female genitalia as given for the genus ; 

 spining of bursa not so dense or continuous as in 

 nigrovittella.

 orella, in AMNH, ex Rutgers) ; Iowa (leucophaeella, in 

 AMNH, ex Rutgers).

 Collection labeled "bred from apple, emerged 25 — V —

 bec, Montreal (July), St. Hilaire (July); Nova Scotia,

There is some mislabeling of the types or, what is more 

 likely, errors in the citation of type localities by Hulst. 

 In his original description of unicolorella he cites "Wash- 

 ington, D. C." and in his 1890 paper gives "Canada." 

 His type is a male (without abdomen) from Iowa, 

 labeled: "H. S. Sanders, June 13, 1886." The type of 

 leucophaeella is a female with typical genitalia, labeled 

 "Colo., Gillette." The type locality citation of "Iowa" 

 in the original description can be written off as another 

 Hulst lapsus, although the species occurs there and is 

 represented by several examples in the National Collec- 

 tion. Barnes and McDunnough (1916) first put leuco- 

 phaeella into synonymy with unicolorella, and there does 

 not seem to be any reason to doubt the correctness of 

 that procedure. The two specimens at Rutgers labeled 

 "type" by Hulst certainly represent one and the same 

 species. 



61. Olybria, new genus 



Type of genus: Myelois aliculella Hulst. 



Tongue well developed. Antenna finely and densely 

 pubescent; on male a sinus and scale tuft in shaft at 

 base. Labial palpus oblique, reaching well above vertex; 

 second segment of male grooved to hold the maxillary 

 palpus ; third segment short, about one-third the length 

 of second, acuminate, partially concealed by scaling of 

 second segment. Maxillary palpus of male in the form 

 of an aigrette; of female small, squamous. Forewing 

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

 outer angle of cell; 2,3, and 4 equidistant at base; 4 and 

 5 shortly separated at base and thence approximate 

 (parallel) for a very short distance; 6 from below upper 

 angle of cell, straight; 8 and 9 stalked for about half 

 their lengths; 10 from the cell, shortly separated from 

 the stalk of 8-9 at base; male without costal fold. Hiad 

 wing with vein 2 from weU before lower outer angle of 

 cell; 3 from the angle, connate with the stalk of 4-5; 

 4 and 5 stalked for half their lengths; 7 and 8 closely 

 approximate for half their lengths beyond cell; cell 



slightly less than half the length of wing; discocellular 

 vein curved, considerably extended at lower angle. 

 Eighth abdominal segment of male with a pair of thin, 

 weak, ventrolateral hair tufts. 



Male genitalia with uncus small, hoodlike, projected 

 downward (at right angle to tegumen) . Apical process 

 of gnathos a short, stout, curved hook. Tegumen with 

 a pair of straight, strongly sclerotized arms projecting 

 backward from its lower, posterior angles. Transtilla 

 absent. Harpe with costa strongly sclerotized through- 

 out its length and produced at apex into a sharp spine; 

 cucullus narrowly elongate, tapering to pointed apex. 

 AneUus a broadly U-shaped band, supplemented (in 

 furciferella) by some sclerotization of the membranous 

 tube surrounding the aedeagus. Aedeagus rather long 

 and stout; penis armed with a single long, strongly 

 sclerotized, rather slender cornutus. Vinculum stout, 

 longer than gi-eatest width, narrowly truncate at 

 terminal margin; the latter very slightly concave. 



Female genitalia with bursa smoothly sclerotized over 

 most of dorsal surface, its ventral surface finely sco- 

 binate with contorted, wrinkled and spined bands more 

 or less encircling the bursa at junction of bursa and 

 ductus bursae; ductus bursae at least as long as bursa, 

 rather broad, flattened (ribbonlike) and waved (twice 

 bent), sclerotized throughout, at genital opening the 

 sclerotization forming a stout, squarish ventral plate; 

 ductus seminalis from a lobe of bursa near junction of 

 bursa and ductus bursae. 



This genus is distinguished from its nearest allies of 

 the Salebria complex by the projecting arms from 

 tegumen of the male genitalia, the ribbonlike, sclerotized 

 ductus bursae and heavy, squarish genital plate of the 

 female, and the simple, paired tufts of the eighth abdom- 

 inal segment of the male. This last character is 

 shared by the genus Salebriacus, which separates from 

 Olybria on other difi^erences of genitalia and venation. 



Two North American species, referred from Salebria 

 (of authors) , represent the only known components of 

 the genus.

Forewing white dusted with black, making the general 

 color ashy gray, the black dusting concentrated on 

 extreme base and in short streaklets on the lower veins 

 at termen; antemedial line narrow, oblique, slightly 

 notched at vein lb, white, bordered outwardly by a 

 black line which begins on costa as a conspicuous, 

 triangular, black spot; on inner margin, preceding the 

 antemedial line, a large orange spot; subterminal line 

 sinuate, narrow, white, bordered inwardly by a narrow 

 black line and outwardly by a broad orange band which
