Moodna; but is structurally an advanced development. 

 As here defined, Moodna is limited to two species from 

 the United States and Mexico {ostrinella Clemens and 

 hisinuella Hampson) . The genus is easUy distinguished 

 from other genera in venational group C by the follow- 

 ing combination of characters: Male antenna with a 

 shallow siaus m. shaft; eighth abdominal segment of 

 male with tuft; hind wing with vein 2 from well before 

 angle of cell and veins 3-5 connate or very shortly 

 stalked; gnathos terminating in a short, simple hook; 

 transtUla iacomplete. 



Two species {Moodna oliveUa Hampson and Hornigia 

 clitellatella Eagonot) that Hampson (Kagonot Mono- 

 graph, pt. 2, pp. 268, 269) includes in the genus are un- 

 known to me, and I am unable to place them generically. 

 They are treated briefly at the end of this paper. 



On the strength of the supposed synonymy of Man- 

 hatta Hulst {=Hornigia Eagonot, 1887), Hampson 

 cites the European biviella Zeller as the type of Moodna. 

 This, of course, is inadmissible, for not only was biviella 

 not among the species originally included in. Moodna, 

 but in describing his genus Hulst designated pelviculella 

 as its type.

Forewing blackish fuscous; basal area strongly shaded 

 with a deep violet red ; terminal area also more or less 

 shaded with the same reddish color; antemedial line 

 distinct, rather wide, nearly straight, white; subterminal 

 line obscure, parallel to termen, shghtly and uxegiilarly 

 denticulate; discal spots distinct, more or less confluent 

 and usually set off by some surrounding whitish dusting 

 which extends, in well marked specimens, to costa. 

 Hind wing smoky white to pale fuscous; veins darkly 

 outlined and a narrow dark shade along terminal mar- 

 gin. Alar expanse, 11-17 mm. 



Male genitalia with inner costal projection from harpe 

 long, slender, tapering, vertical from costa; outer pro- 

 jection curved outwardly, the two projections pointed 

 away from each other. Uncus with sides nearly paral- 

 lel. Vinculum evenly tapering. Female genitalia with 

 ductus bursae weakly sclerotized toward genital opening. 



Type localities: Pennsylvania [?] {ostrinella, type 

 lost) ; Texas {ohtusangulella, in Paris Mus.) ; Newburgh, 

 N. Y. {pelviculella, in AMNH, ex Eutgers). 



Food plants: Betula, Rhus, Quercus, rose, pear, 

 peach, apple, loquat, iris, cotton, Pinus. The larva is 

 more or less a scavenger, feeding on dried seeds and 

 mummied fruits, on dry rose buds, and in galls on roses, 

 in acorns and old cotton bolls. Its favorite food in the 

 neighborhood of Washington, D. C, seems to be the 

 racemes of Rhus. It has much the habits of an Ephestia 

 except that it is an outdoor insect and does not attack 

 stored products to any extent.

587. Moodna bisinuella Hampson 



Figures 600, 1087 



Moodna bisinuella Hampson, in Ragonot, Monograph, pt. 2, 

 p. 268, 1901. 



Forewing blackish fuscous with transverse lines 

 obscure; on fresh specimens some reddish scaling in 

 basal area and along the folds (visible only under 

 magnification) ; antemedial line as in ostrinella but very 

 faint; discal spots usually distinguishable and more or 

 less confluent. Hind wing whitish with apical area 

 somewhat smoky; the veins and a line along terminal 

 margin considerably darker. Alar expanse, 17-22 mm. 



Male genitalia with inner costal projection from 

 harpe curved outwardly; outer projection curved in- 

 wardly, the two projections pointed toward each other. 

 Uncus with sides strongly convex. Vinculum sharply 

 angled at anterior end. Aedeagus considerably stouter 

 than that of ostrinella. Female genitalia with ductus 

 biu"sae strongly sclerotized and striated towards genital 

 opening. 



Type locality: Orizaba, Mfeico (type in USNM; 

 para types in BM) . 



Food plant: Corn. 



Disteibution: Mexico: Matamoros (July, Aug.), 

 Orizaba, Tehuacdn (Sept., Oct.). United States: 

 Texas, Crystal Springs (Oct.), Weslaco (June). 



Larvae of bisinuella have been frequently intercepted 

 in ears of green corn from Mexico at border ports by 

 the Division of Foreign Plant Quarantine of the 

 U. S. Bm'eau of Entomology and Plant Quarantine.
