Female genitalia without signum; bursa finely and 

 densely spined over most of inner surface and with a 

 cluster of longer and stronger spines near middle of 

 lateral margin; ductus bursae short (less than half the 

 length of bursa) ; armed on ventral surface by an elon- 

 gate pair of granulate plates; at genital opening a 

 strongly sclerotized, centrally interrupted genital plate, 

 attached to a narrow, sclerotized collar (incomplete 

 dorsaUy and ventraUy) and supplemental to the regular 

 eighth-segment collar; ductus seminalis from bursa near 

 junction of bursa and ductus bursae. 



The genus is close to and has several characters in 

 common with both Meroptera and Nephopteryx, resem- 

 bling the former in the well developed genital plate of 

 the female genitalia and the strong, serrate clasper of 

 the male, differing from both genera in the rough scaling 

 on forewing, the ungrooved labial palpi and much 

 stouter antennal tuft of the male, the sharply curved 

 cornuti on penis, and the supplemental collar attached 

 to the female genital plate. As here defined it contains 

 only its American type species.

In color and maculation similar to the European 

 Nephopteryx rhenella except for the raised scaling of the 

 subbasal black bar. 



Forewing duU ash gray with pm-phsh brown shading 

 at extreme base and paler brownish shading on outer 

 median and terminal areas; antemedial line complete 

 but faint, narrow, oblique, slightly indented on lower 

 haK, preceded by a broad black band of rough scales 

 and followed by a narrow black band; subterminal line 

 obscure, sinuate-dentate, faintly bordered by dark inner 

 and outer lines; discal dots distinct, blackish, separated; 

 a row of faint Islackish dots along termen. Hind wing 

 pale smoky fuscous; the veins very slightly darkened 

 and a narrow dark line along termen. Alar expanse, 

 17-23 mm. 



Male genitalia with cornuti set side by side near outer 

 end of penis, their apices turned away from each other. 

 Female genitaha as given for the genus. 



Type localities: Honduras [sic] {reductella, in BM); 

 District of Columbia (glediischiella, in USNM) . 



Food plant : Gleditsia. Larva a leaf-tier. 



Distribution: District oj Columbia (May, July); 

 Maryland, Plummers Isl. (June); North Carolina, Hil- 

 tonhead Isl. (Aug.); Pennsylvania; Illinois, Decatur 

 (Mar., Apr., May, July), Quincy (May); Iowa, Ames; 

 Kansas, Lawrence (May); Missouri, St. Louis (May); 

 Texas, Kenedy (Apr.), Paris (May), Victoria (July), 



ZavaUa County (Apr.) ; Louisiaria, Crown Point (June, 

 larva). New Orleans (larva, June). 



Walker gives Honduras as the type locality. I 

 rather doubt the correctness of this citation, for I have 

 never seen anything from Central America that even 

 remotely resembled the species. I have not seen his 

 types, but have no reason to question the correctness of 

 Ragonot's reference of gleditschiella to synonymy. 



70. Tulsa, new genus 



Type of genus: Nephopteryx finiiella Walker. 



Characters of Tlascala except: 



Forewing with some rough scaling in the median 

 area beyond the outer margin of the antemedian line, 

 sometimes a small tuft on lower fold, always a few 

 roughened scales in the discal spots; veins 4-5 approxi- 

 mate at base and for a short distance beyond. Male 

 genitalia with sacculus of harpe considerably enlarged, 

 strongly sclerotized, densely and finely spined along 

 entire lower margin, and produced at apex; clasper a 

 thin, dished plate produced into an elongate, curved, 

 sharply pointed claw at each lower angle. Uncus 

 broadened at apex. TranstiUa complete, very weakly 

 but evenly sclerotized throughout. Cornuti straight, 

 set one before the other. Female genitalia with several 

 lines of fine spines running from bursa into ductus 

 bursae almost to genital opening; genital plate and its 

 attached supplemental coUar strongly wrinkled (more 

 so than shown in the figures) ; no granulations in ductus 

 bursae. 



The genus is very close to Tlascala and I propose the 

 new name with some misgiving; but the habitus of the 

 moths and their genitalia, male and female, differ so 

 much from those of the type of Tlascala that something 

 more than a species-group difference is indicated. When 

 larvae and host relations of the Tulsa species are known 

 we shall probably find additional supporting characters 

 for the genus. Specifically the genitalia are remarkably 

 similar, offering little or nothing to distinguish the 

 species. Four are here recognized.

Forewing very dark gray with the blackish borders of 

 the antemedial and postmedial lines but slightly con- 

 trasted; some slight dusting of white on subbasal, me- 

 dial, and terminal areas; antemedial line somewhat 

 stronger, its inner blackish bordering line more or less 

 interrupted on the veins, its outer border continuous 

 but faint; discal dots tending to coalesce; an obscure 

 row of blackish dots along termen; raised scales con-
