REVISION OF THE OECOPHORIDAE — CLARKE 95 



Labial palpus pale ochreous; second segment irrorated exteriorly 

 with fuscous ; third segment with subbasal and median bands fuscous. 

 Antenna fuscous. Head, thorax, and ground color of fore wing light 

 ochreous; the thorax, except collar, and fore wing, except base and 

 basal third of costa, strongly overlaid and suffused with brown ; fore 

 wing sparsely irrorated with black scales, more so in distal half; a 

 spot at extreme base of costa, one subcostally and another on inner 

 angle near base, black; at basal third two conspicuous, black discal 

 spots, one above the other, surrounded by a pale ochreous shade, the 

 latter followed by a poorly defined fuscous cloud ; at the end of cell 

 a poorly defined whitish-ochreous spot; along costa, around termen to 

 inner margin a series of small fuscous spots; cilia pale ochreous- 

 fuscous edged outwardly with pale ochreous. Hind wing grayish 

 fuscous ; cilia somewhat lighter with ochreous-fuscous terminal band. 

 Legs pale ochreous slightly irrorated and suffused with fuscous. Ab- 

 domen light ochreous, suffused with fuscous. 



Female genitalia, — Genital plate moderately narrow with a strongly 

 sclerotized, slightly produced anterior edge. Ostium large, occupying 

 most of length of genital plate. Ductus bursae very long, gradually 

 tapering into the large asymmetrical bursa copulatrix. Inception of 

 ductus seminalis on right side of ductus bursae just before ostium. 

 Bursa bulged out to the right, the evaginated part annulated with a 

 series of concentric ridges ; the signum is a moderately large, strongly 

 sclerotized, toothed plate with well developed anterior and posterior 

 points and is situated at the periphery of the evaginated portion of 

 the bursa copulatrix. 



Alar expanse, 18-25 mm. 



Type. — In the Academy of Natural Science of Philadelphia, 



Type locality. — "Pennsylvania." 



Food plant. — Baptisia tinctoj^ia R. Brown. 



Dis-tnhution. — Known only from the type locality (presumably 

 Pennsylvania) and one other specimen from Arendtsville, Pa. (7-4-29, 

 S.W.Frost). 



Remarks. — In the National collection there is a single female of 

 this species. Aside from the type it is the only other specimen I 

 have seen. Everything else I have seen in the collections under this 

 name is referable to other species and is dealt with accordingly. 



This species can be distinguished from the others with which it 

 has been confused by the pale area surrounding the two conspicuous 

 black discal spots at basal third, by the pale whitish-ochreous spot 

 at the end of the cell, and by the strong signum of the bursa. 



This species is not included in the key based on gentalia.
