femora all exposed; antennae not meeting in the middle line and not 

 reaching the end of the wings; tongue moderate or reaching end of 

 wings; prothorax and dorsal head piece both rather narrow, distinct, 

 and sub-equal; niesothorax extending back as a long lobe in mid-dorsal 

 line, nearly cutting the metathorax in two. 



The Grlyphipterygidae are a small and homogeneous family, with a dis- 

 tinct relationship to the Tortricidae with which they have sometimes been 

 united. They are very close to the Yponomeutidas in adult characters, 

 but well separated from them in the early stages, especially by the nor- 

 mal incomplete pupa. There are about 550 species, largely Oriental. 

 ISetiostoma, formerly placed here, belongs near Stenoma. 



Key to the genera, 



1. Third joint of palpus twice as long as second, smooth 1. Abrenthia. 



1. Third joint of palpus but little if at all longer than second. 



2. Second segment of palpus with long hair below, about as long as the 

 segment 3. Choreutis. 



2. Palpus not reaching vertex; with rough-scaled second joint.. 2. Simaethis. 



2. Palpus smooth, upturned beyond vertex 4. Glyphipteryx. 



1. ABRENTHIA Busck 



Wings ample; venation as in Glyphipteryx; fore wing with cell two-thirds as 

 long as wing; hind wing widening outward, as in Glyphipteryx, with cell half as 

 long as wing. Palpus with third segment longer than first and second together; 

 smooth. 



1. A. cuprea Busck. Deep purple; head and tegulse golden bronze, thorax 

 darker. 11 mm. 



Late June and July. 



Quebec; Pennsylvania; Virginia. 



2. SIMAETHIS Leach 



(With Brenthia Clemens, Orchemia Guenee, Hemerophila Hiibner 

 (Tentamen), Allononyma Busck) 



Fore wing (fig. 212) triangular with moderately short outer margin and marked 

 anal angle; hind wing rounded-triangular, with anal region broad, and all veins 

 developed; 3d A long. Cells of moderate length. Wings marked with metallic 

 scales. Palpi with second and third joints slightly thickened with rough scales. 



Our four species represent three different groups. The first three occur also 

 in Europe, most of the relatives of the fourth are tropical. 



T. Fore icing more perfectly triangular, with marked apex; outer margin concave 

 above and below middle, the fringe marked there with white. Palpus with 

 third joint cylindrical; thick in side view. Fore wing with R 4 and R 5 normally 

 separate ( Simaethis ) . 



1. S. fabriciana Linnaeus. Mottled dull brown, with obscure markings suggest- 

 ing a small noctuid; the two white streaks in fringe covering two-thirds of the 

 width of the fringe, contrasting. 12 mm. 



June. Larva on nettle," etc. Dull yellowish; head black; clypeus and a couple 

 of spots on cheeks pale; cervical shield, anal plate, and true legs black; the shield
