Palpi white, second segment with a little gray, third with outer half except extreme 

 tip black. 22 mm. ( asterella, in error ) . 



Caterpillar in a more or less triangular gall on top of dwarfed stems of Solidago 

 latifolia, ccesia, axillaris, and Aster dwai-icatus, the forms of the gall differing 

 with the plant. Hole cut and plugged before pupation. 



Canada to Pennsylvania and Michigan. New York : Ithaca. 



5. G. gallaesolidaginis Riley. Powdery gray, including head and palpus; most 

 of the scales pale at base with a heavy black bar and fine white tip. Basal half 

 of third segment of palpus contrastingly pale; fore wing with middle half of 

 wing toward costa heavily shaded with brown o*" brownish black, contrasting, 

 and with the boundary toward base oblique and fairly definite. Some dark shading 

 also near base of inner margin and toward apex. 22 mm. 



Caterpillar in stems of goldenrod, not stopping the growth of the plant, but often 

 slightly dwarfing it; forming a fusiform gall. Pupa in a silk hammock suspended 

 opposite the emergence -hole, which is plugged. Parasitized caterpillars {Copidosoma 

 gelechice) grow abnormally large and die before cutting the exit-hole. The moth 

 emerges in late August, and is said to hibernate occasionally. The eggs are normally 

 laid in the fall, and hibernate. 



General in distribution and not rare. New York: Vicinity of Buffalo, Ithaca, 

 Big Indian Valley, Albany; Richmond Hill, Long Island. 



6. G. salinaris Busck. Closely similar to G. gallcesolidaginis but averaging slightly 

 smaller and broader winged; band on third segment of palpus less definite; fore 

 wing with markings slightly more diffuse and tending a little to longitudinal stria- 

 tion. 20-22 mm. 



The moth flies early in September. The larva hatches the same year, but does 

 not begin to form the gall till the following spring. The gall is similar to that of 

 G. gallcesolidaginis, but usually nearer the ground; in Solidago salinaris. 



Coast of Massachusetts. 



7. G. subterranea Busck. Body blackish, dusted with white. Antennae with 

 black, brown, and white; fore wing rich reddish to chocolate brown, irregularly 

 sprinkled with blackish, white- tipped scales; fringe whitish, brown-powdered. 

 Hind wings yellowish fuscous with grayer fringe. Abdomen as usual, with yellow 

 at base. 18 mm. 



Early September. Galls small, about 15 mm. long, at the bases of the clustered 

 stems of Aster multiflorus ; usually in a cluster. 

 Boston, Massachusetts. 



8. G. busckiella Kearfott. Dull black, dotte'd all over evenly with the white 

 scale-bases; a few of the scales also narrowly white-tipped. Head, thorax, and 

 palpi also mainly black. Hind wing blackish fuscous. 18 mm. 



The caterpillar forms a long, cylindrical gall in the side-branches of Aster patens 

 dwarfed by Thiodia radiatana, and stops the growth of these side-branches beyond 

 the galls. The larva may be found in July and August, the moth in November. 



Northern New Jersey. 



9. G. brackenridgella Busck. Moth similar to G. subterranea but with the whole 

 wing, including the fringe, brownish, and strongly suffused with pink, and also 

 the head, palpi, and thorax. No definite markings but traces of a longitudinal 

 shade rather below middle of wing outwardly. 20 mm. 



Gall quite like G. gallcesolidaginis, but smaller; in stem of aster. Moth in 

 October. This may be the same as G. septentrionella Fyles. 

 Magnolia, Massachusetts. 



10. G. triocellella Chambers. White, contrastingly shaded and dusted with black; 

 whitish ante- and postmedial white fasciae, converging toward inner margin, a 

 little diffuse, and defined with black shades. Large black antemedial and 

 discal dots, and a similar dot in fold, ringed with white and buff, and with some 

 buff shading near base. 12 mm. 



Colorado; reported by Dietz from New Jersey.
