Lepidoptera op New York and Neighboring States 181 

 5. LEUCANTHIZA Clemens 



Front and vertex smooth, a small, loose tuft on occiput; antennae as long as fore 

 wings, basal joint small, not modified; palpi short, straight, drooping; maxillary 

 palpi rudimentary; tongue short, apparently naked; hind tibia? with long bristly 

 hair ( ?). Fore wing lanceolate (fig. 118), with four traceable veins running to 

 costa, Rj being lost; two or three veins from cell to inner margin. Hind wing with 

 R and M t closely parallel, but without forked veins. 



Caterpillar of Gracilariid type, forming a large blotch-mine on upper side of a 

 leaf. Cocoon of white silk, outside the mine. At rest the moth holds the antenna? 

 extended laterally, as do other members of the family. This is an aberrant genus, 

 which has not been fully studied, and may be misplaced in the keys. The short 

 palpi may cause it to be sought among the Lyonetiida?; and there may be a real 

 kinship to Phyllocnistis. 



Key to the species 



Base of inner margin brown amphicarpecefolieUa. 



Base of inner margin golden dircella. 



1. L. amphicarpeaefoliella Clemens. Head lead color; antenna? golden brown, tips 

 silvery white. Fore wings deep orange, shading to golden brown toward the apex; 

 base deep brown, bordered by a strongly excurved, lead-gray line from costa to 

 basal' angle; a large, irregular, triangular, golden patch on middle of inner margin, 

 extending up nearly to middle of wing; a golden streak at beginning of costal 

 fringe, with two dots before it; fringe golden brown; hind wings gray. 6 mm. 



May. Larva in an upper surface mine, on Amphicarpa mcmoica; green with 

 brown dorsal, and darker ventral, spots, after the last molt becoming wholly green. 

 Connecticut; Maryland; Pennsylvania. 



2. L. dircella Braun. Orange yellow; head golden with darker hairs behind; 

 antenna? dark brown, tips silver white; thorax golden, dark brown in front. Fore 

 wing with base dark brown, except toward inner margin; apical area dark brown; 

 antemedial golden fascia? straight. Base of inner margin orange; an oblique, 

 curved golden streak from antemedial region below costa to middle of costa ; a small, 

 costal streak at beginning of fringe; a short, golden, dorsal streak margined 

 toward base by an oblique line, dark brown scales; a longer oblique streak at anal 

 angle, and a faint, golden, marginal line. Fringe and hind wing dark brown. 

 Legs golden with dark brown tarsi. 5-6 mm. 



July. Larva in late June and in September, in a large, sometimes digitate, upper- 

 side blotch, on Dirca palustris; often social. Cccoon outside the mine. 

 Clermont County, Ohio. 



6. MARMARA Clemens 



(JEsyle Chambers; Gracilaria, in part) 



Head smooth; antenna? with pecten scaly and suggesting an eye-cap, or normal; 

 palpi moderate, smooth-scaled, ascending in life but usually porrect when dry; 

 maxillary palpi moderate, porrect; tongue naked. Tibia? smooth-scaled. Fore 

 wing (fig. 117) with only five veins arising from the cell, three running to the 

 costa and two to the inner margin, all free. Fringe as usual in the family. Hind 

 wing linear-lanceolate, with fringe four times as wide as membrane; Sc and R 

 obscure; a forked stem in middle of wing, free from Rs; Cu simple. 



The larva? are of the flattened type in all the feeding stages, becoming cylindrical 

 just before pupation. They are extremely broad at the anterior end and lobed 

 at the sides. They are leaf miners, or miners in the bast of twigs, usually form- 

 ing a tract. The cocoon is spun outside the mine and is covered with more or less 

 confluent masses of pearl-like, white bubbles. The genus is only definitely known 

 from North America, but has been generally confused with Gracilaria. Besides the
