broad, its lateral lobes wide and widely spaced, their 

 apices narrowly rounded ; harpe with cucullus broaden- 

 ing toward apex; vinculum about as broad as long; 

 uncus abruptly narrowed beyond base, thence tapering. 



Female genitaUa with bursa large, densely spined and 

 wrinkled towards junction with ductus bursae; ductus 

 bursae very short, deeply wrinkled. 



Type locality: New York (in AMNH, ex Rutgers) . 



Food plant: Liriodendron tulipvfera. 



Disthibution: New York, Long Island; District oj 

 Columbia, Washington (June); Maryland, Oxon Hill, 

 Plummers Isl. (Oct.); Virginia, Leesburg; South Caro- 

 lina, Greenville (June), Hendersonville (June), Paris 

 Mountain (June), Eockhill (June), Yorkville (June); 

 Georgia, Atlanta (Oct.). 



Probably distributed throughout the range of its host. 



This distinct species apparently has only one host, the 

 "tulip tree." The larva bores in the bark on the damp 

 side near the base of the tree.

Euzophera griselda Dyar, Proc. IJ. S. Nat. Mus. vol. 44, p. 322, 

 1913 (new synonymy). 



Forewing gray evenly dusted with blackish; trans- 

 verse pale lines paler, but obscure, shaped as in the pre- 

 ceding species; antemedial line with an obsciu-e narrow 

 blackish outer border; sub terminal with faint dark bor- 

 ders on iimer and outer sides; a whitish spot on disco- 

 cellular vein; terminal dots, faint, blackish. Hind wings 

 white with some dark shading on the veins and along 

 terminal margin. Alar expanse, 21-27 mm. 



Male genitalia with lateral projecting lobes of trans- 

 tilla largest of any known American Euzophera; anellus 

 longer than broad, the lateral lobes untapering, nar- 

 rowly spaced, and with outer margins at apices inwardly 

 hooked; harpe with cucullus stubby, its lower margin 

 slightly concave; vinculum as broad as long; uncus as in 

 ostricolorella. Female genitalia with a wrinkled sclero- 

 tized coUar about ductus bursae at its junction with 

 bursa copulatrrx. 



Type localities: Arizona (nigricantella; in Paris 

 Mus.); Tehuacdn, Mexico (griselda, in USNM). 



Food plant: Unknown. 



Distribution: United States: Arizona, Baboqui- 

 vari Mts. (Apr., June, July, Aug., Sept., Oct.), Reding- 

 ton, Tempe (Mar.), Yavapai County; New Mexico, Al- 

 buquerque (July) ; Texas, San Benito (May) . Mexico: 

 Sonora; Tehuac^n (May, Sept.), San Jose de Guaymas 

 (Apr.). 



Dyar's griselda was described from females which 

 match specimens of nigricantella from Arizona in every 

 detail of macula tion, color, and genitalia. At the time 

 he described griselda Dyar had not recognized Ragonot's 

 species. 



164. Exuperius, new genus 



Type of genus: Exuperius negator, new species. 



Tongue well developed. Antenna simple, pubescent. 

 Labial palpus upturned, barely reaching to vertex; first 

 segment broadly scaled ; third segment nearly as long as 

 second, acuminate. Maxillary palpus minute, filiform. 

 Forewing smooth; 11 veins; vein 2 from before lower 

 outer angle of cell; 3 from the angle; 4 and 5 stalked (for 

 less than half their lengths) , separate from 3 at base: 6 

 slightly bent, from below, but near upper angle of cell; 

 8 and 9 rather long stalked (for two-thirds their lengths) ; 

 10 from the cell, approximate to the stalk of 8-9 for 

 some distance; male without costal fold. Hind wing 

 with vein 2 from well before lower outer angle of cell; 

 3 and 5 connate, from the angle; 7 and 8 anastomosed 

 beyond cell for most of their lengths (free segment of 8 

 short); cell long, slightly over half the length of wing; 

 discocellular vein curved. Eighth abdominal segment 

 of male simple. 



Male genitalia with apical process of gnathos de- 

 veloped as an elongate, stout, simple hook with pointed 

 apex. Uncus narrow, constricted towards base, shaped 

 like a narrow, bluntly pointed arrowhead. Transtilla 

 complete, but median portion a narrow, rather weakly 

 sclerotized band. Harpe with broadened, evenly 

 rounded cucullus; spoon-shaped; costa broadly sclero- 

 tized but not produced; clasper present, short, knobbed 

 at apex; from near base of cucullus a strong, long, semi- 

 detached hair tuft. Anellus a broadly U-shaped nar- 

 row band with long, flattened, lateral projections. 

 Aedeagus long, stout; penis armed with a dense mass of 

 minute granulations. Vinculum considerably shorter 

 than broad, terminal margin broadly and evenly 

 rounded. 



Female unknown. 



This genus is close to Euzophera and agrees with it in 

 characters of venation, labial palpi, and gnathos; but its 

 peculiar genitalia (aside from the apical projection of 

 gnathos) differ in every detail from those of typical 

 Euzophera and suggest a separate generic designation. 

 They resemble those of no other American group that 

 I know. The partial forking of vein lb of forewing at 

 base (shown in fig. 76) is present on both forewings but 

 may be an individual abnormaUty. It is most unusual 

 for a phycetine. 



566. Exuperius negator, new species 

 FiGiTREs 76, 584 



Forewing brown, dusted with grayish white over basal 

 area and for a short distance beyond antemedial line 

 near costa and inner margin; some blackish dusting in 

 cell beyond its middle and a black spot on costa on each 

 side of the sub terminal line; antemedial line indicated 

 by a blackish band slanting slightly inward from slightly 

 beyond basal third of costa to inner margin, straight; 

 subterminal line somewhat wavy, obscure except on 

 costal half where it is distinctly white; a small but con- 

 spicuous white spot above the stalk of veins 4-5 at end 

 of cell; terminal dots blackish, more or less confluent.
