Gracilaria hypericella, n. sp. 



Face whitish; palpi whitish, with the tip of the maxillary 

 palpi and the tip of the second segment of the labial palpi and 

 outer and upper surface, and sometimes the entire apical half of 

 the third segment except the extreme tip, blackish. Head ochreous, 

 more or less overlaid with fuscous purple. Ground colour of the 

 fore wing ochreous, more or less overlaid with shining jaurplish 

 fuscous: usually the costal third of the wing, except toward base 

 and in the apical fourth, is comparatively free from purplish dust- 

 ing. There is a series of minute fuscous dots on the costal edge; in 

 darker specimens sometimes indistinctly continued across the wing. 

 The dark scales form an indistinct spot in the middle of the disk. 

 Cilia fuscous, with three or four indistinct, darker lines running 

 through them. Hind wings and cilia gray. Fore and middle 

 legs black, except the tarsi; hind legs whitish dusted with fuscous; 

 tarsi white with black tips. 



Expanse 8.5-10 mm.

Types in author's collection. 



Seventeen specimens, reared from larvae on St. John's Wort, 

 Hypericum cistifolium, and H. punctatiim. The larva makes a 

 small linear mine, usually distinctly visible on the upper side of 

 the leaf; this mine enlarges into an elongate blotch on the under- 

 side, 7 or 8 mm. long and 2 mm. or less wide, which becomes 

 tentiform, resembling a minute Lithocolletis mine. The cone is 

 rolled from the tip of the leaf downward on to the lower side, usually 

 taking up the entire small leaf. The cocoon is spun on the under- 

 side, the leaf being curled over so as entirely to conceal the cocoon. 

 On leaves of Hypericum cistifolium., the cocoon is almost always 

 placed near the tip over the midrib, and the leaf on both sides is 

 curled over the cocoon. Larvae and cocoons collected July 20 

 .. and August 27; one captured specimen July 8. 



This species is close to G. desmodiella, but lacks the violet tint 

 of that species and the discal spot is never distinct. 

 Gracilaria ferruginella, n. sp. 



Labial palpi densely dusted with reddish fuscous outwardly, 

 yellowish on inner side, with third segment slightly dusted except 

 at extreme tip; third segment thickened with scales to near apex. 

 Head and thorax purplish brown, slightly mixed with ochreous.
