REVISION OF THE OECOPHORIDAE CLARKE 125 



Female genitalia. — Genital plate moderately sclerotized; anterior 

 edge lobed. Ostium small, round, opening about middle of plate. 

 Ductus bursae short, not much longer than bursa copulatrix; incep- 

 tion of ductus seminalis just before ostium. Bursa copulatrix large, 

 oval, without signum. 



Alar expanse, 16-17 mm. 



Type. — In the United States National Museum. 



Type locality. — Palm Beach, Fla. 



Food plant. — Ainyris -jioridoma Nutt. 



Remarks. — This species is represented only by the type series. 

 These are females. 



2. MARTYRHILDA, new genus 



Plate 2, Figure 17 ; Plate 6, Figuee 44 ; Plate 10, Figures 67, 67a ; Plate 16, 



Figure 100 



Genotype. — Depressaria canella Busck, Proc. U. S. Nat. Mus., vol. 

 27, p. 764, 1904. 



Similar to Agonopterix but palpus more slender, smooth, brush on 

 second segment poorly developed or absent. Fore wing narrow, 

 elongate, bluntly pointed; costa straight. Hind wing with costa 

 straight or slightly excavate. Abdominal wall strongly sclerotized. 



Male genitalia. — Clasper divided, with transverse arm and longi- 

 tudinal arm, the former sometimes with lateral process from inside; 

 gnathos broadened, sometimes renifonu; vesica usually armed with 

 strong cornuti. 



Female genitalia. — Signum always large, broadly oval to elongate, 

 never diamond-shaped. Ductus bursae membranous or partly sclero- 

 tized, sometimes with strong thornlike processes from inner surface. 



Larva. — ^As in Agonopterix. 



Pupa. — Pubescent. Prothoracic femora exposed. Labial palpi not 

 exposed. Cremaster absent. 



Remarks. — ^This genus is closely related to Agonopterix., differing 

 from it by the poor development or absence of the brush of the second 

 segment of the labial palpus, the divided clasper of the harpe, the 

 unusually large broadly oval or elongate signum, and the exposed 

 prothoracic femora of the pupa. 



With the genotype I associate ten other species, three of which I 

 have described as new. 



The larvae of only three species of this genus are known. The larva 

 of sphaeralceae is a leaf miner ; those of umhraticostella and canella 

 are leaf tiers.
