bling, in outline, a bulbus-necked bottle). Uncus 

 broader than long; sides nearly parallel; terminal margin 

 broadly rounded. Transtilla incomplete; elements mi- 

 nute, folded. Harpe short; appressed clasper well out 

 towards outer margin of harpe; from base of costa a 

 long, stout, curved, strongly sclerotized and pointed 

 clasperlike horn projects across face of harpe. Anellus 

 a flattened plate. Aedeagus short, stout, slightly sinu- 

 ate, and with apex sharply constricted; armed with a few 

 short spines near apex; penis with a small patch of fine 

 scobinations, otherwise unarmed. Vinculum stout, as 

 broad as long, tapering to truncate terminal margin. 



Female genitalia with bursa copulatrix finely scob- 

 iuate throughout, otherwise simple, without signiun; 

 ductus bursae sclerotized, broad and very short, broad- 

 ening abruptly into the sclerotized and thickened lower 

 lip to an exceptionally wide genital opening; ductus 

 seminalis from bursa near its junction with ductus 

 bursae. 



A striking genus easily identified by venation and 

 genitalia. Contains one North American species. 



415. Patriciola semicana, new species 

 FiGUHEs 84, 460, 953 



Forewing ashy grajdsh white on costal half; shaded 

 with faim brown rather heavily dusted with blackish 

 fuscous on lower half, especially from base to antemedial 

 line and shghtly beyond; veins partially outlined by 

 dark scaUng; antemedial line distinct only from cell to 

 inner margin, far out towards middle of wing, white, 

 narrow, evenly incurved; sub terminal line very faint, 

 nearly obsolete, parallel to and rather far in from 

 termen; lower discal dot at end of cell, large, distinct 

 and blackish, a similar smaller black spot in ceU over 

 the antemedial line. Hind wing semihyaline, smoky 

 white; veins not darkened and terminal margin only 

 faintly so; cilia concolorous with wing. Alar expanse, 

 25-26 mm. 



Genitaha as given for the genus. 



Type locality: Provo, Utah (tjrpe in USNM, 

 61367). 



Food plant: Unknown. 



Described from male type and two female paratypes 

 from the type locality, collected by Tom Spalding July 

 16, 1909 (cf ), and Aug. 4, 1908 (99). In habitus sem- 

 wana resembles most some specimens of Honora but is 

 easily separable from anything in that genus. 



117. Paconius, new genus 



Type of genus: Paconius corniculatus, new species. 



Tongue well developed. Antenna pubescent; shaft 

 of male with sinus and small scale tuft at base. Labial 

 palpus upcurved, rough scaled, reaching to vertex; third 

 segment about haK the length of second, acuminate. 

 Maxillary palpus squamous. Forewing smooth; 11 

 veins; vein 2 from before the lower outer angle of cell; 

 3 from very close to angle; 4 and 5 approximate for some 



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

 straight; 8 and 9 stalked; 10 from the cell, shortly 

 separated from the stalk of 8-9; male without costal 

 fold. Hind wing with vein 2 from before lower outer 

 angle of cell; veins 3 and 5 contiguous for a short dis- 

 tance from angle (touching but not fused at any point) ; 

 7 and 8 contiguous for less than half their lengths beyond 

 cell; cell about half the length of wing; discocellular 

 vein curved. Eighth abdominal segment of male with 

 a weak pair of ventrolateral hair tufts. 



Male genitalia with apical process of gnathos nar- 

 rowly triangulate and acutely pointed. Uncus irregu- 

 larly triangulate, tapering to narrowly rounded apex. 

 Transtilla absent; elements not distinguishable. Harpe 

 divided to base with entire costa developed as a strongly 

 sclerotized, long, hornlike projection; remainder of 

 harpe much reduced, triangulate and tapering to a 

 point; clasper absent. Anellus a narrow, slightly 

 curved plate with very long, slender, lateral arms. 

 Aedeagus long, slender, abruptly bent toward apex; 

 armed at apex with two thornlike spurs; penis armed 

 with a cluster of short, rather stout spines. Vinculum 

 stout, slightly longer than broad, very shghtly tapering 

 to broad, evenly rounded, terminal margin. 



Female unknown. 



Paconius has much the same venation, palpi, and 

 antennae as the European genus Psorosa; but differs 

 markedly in genitaha. In Psorosa the harpe is simple 

 and the gnathos, vinculum, and anellus entirely different. 

 Paconius has several features in common with PairicioZa, 

 with which it appears to be most closely related, dif- 

 fering most from that genus in its upcurved rather than 

 porrect palpi. I dislike very much describing a new 

 genus without having females for completion of the 

 diagnosis on genitalic characters; but it is so obviously 

 new and the male genitalia so different from anything 

 else in our fauna that it seems advisable to give it some 

 designation. 



416. Paconius corniculatus, new species 



FiGUEB 464 



Forewing pale ashy gray; transverse lines nearly ob- 

 solete; antemedial line faintly outlined, nearly straight, 

 slanting outwardly from costa to inner margin, indicated 

 chiefly by a small blackish spot on its inner border a,t 

 inner margin and a couple of short blackish streaks on 

 its outer border near costa; costal edge at base of wing 

 blackish; subterminal line not defined except by a few 

 blacldsh, inwardly bordering streaks near costa. Hind 

 wing semihyaline white with a narrow fuscous shade 

 along costa and outer margin. Alar expanse, 19 mm. 



Male genitalia as given for the genus. 



Type locality: San German, Puerto Eico (type in 

 Cornell Univ.; paratype m USNM, 61368). 



Food plant : Unloaown. 



Described from male type and one male paratype 

 from the type locality collected Apr. 16 and 17, 1930, 

 under Cornell lot 795, sub. 34 and 36.
