270 WILLIAM T. M. FORBES 



This species is rather similar to some forms of the bicostomaculella group, but 

 with no blue tint, and with the hair pencil very weak. In dark specimens the 

 yellow base may be almost obliterated; in light ones it is continued by a band 

 along the inner margin to beyond its middle. This is one of our species which 

 come closest to the subgenus Lita, but its hind wings are too bror.d to oe typical. 

 10-15 mm. (vagella Walker, fuscoochrella Chambers, Lita liturosella Zeller). 



Early spring; July. Larva in seeds of Ambrosia trifida. 



General in distribution and not rare. New York : Peru, Rock City, ( Cattaraugus 

 County ) , Crosby, Potter Swamp ( Yates County ) . 



30. G. walsinghami Dietz. Palpi ash gray; outer side of first and base of second 

 joints fuscous; tuft divided, dusted with fuscous; third joint dusted with fuscous, 

 with a broad dark ring. Antennae faintly annulate. Head, body, and fore wings 

 gray; a dark brown posterior spot on thorax. Fore wing marked with dark rich 

 brown; a triangular sub-basal patch, not reaching costa; a longitudinal stripe 

 through middle of apex, defined below and interrupted by a pale postmedial fascia 

 which is defined inwardly and preceded with brown at costa. Some raised white 

 scales in fold. 15 mm. (Pseudochelwria Dietz). 



Late May to July. Caterpillar pale green, in a white web on under side of leaves 

 and along petioles of Rhus typhina in late August and September. 

 Western Pennsylvania; Anglesea, New Jersey. New York: Ithaca. 



31. G. pennsylvanica Dietz. Similar to G. walsinfjhami. Dark basal area extended 

 outward toward end of cell, where it joins the longitudinal streak, and reaching 

 base of inner margin; the transverse fascia less conspicuous. 15 mm. 



July. 



Western Pennsylvania. 



32. G. tephriasella Chambers. Pale gray, dusted with white; palpi dark brown, 

 second joint white-tipped, third white-dusted, with a white annulus; antennae light 

 gray and white, with three or four strong annuli towwrd tip (like Aristotelia 

 absconditella and Duvita conclusella). Fore wing with each gray scale white- 

 tipped; wing darker toward apex; a narrow, white fascia at beginning of fringe, 

 an oblique streak from costa before middle, and obscure darker terminal dots. 

 10 nun. 



Kentucky. Type lot only known. 



33. G. nundinella Zeller. Pale buff or cream, with yellow-brown shading and 

 sparse black dusting, tending to form longitudinal striation toward border and 

 oblique shading on disc. Palpus pale with two brown patches each on second and 

 third segments. Hind wing somewhat grayer. 20 mm. (beneficentella Murtfeldt). 



Caterpillar on Solatium carolinense, the first brood webbing the terminal leaves 

 into a hollow ball, the second brood in the berries. Pupa in the nest. Larva with 

 head and cervical shield black when young, olive-brown when mature. Body yel- 

 lowish green with dark glaucous dorsal stripe. 



District of Columbia; Texas; Missouri. 



As the moth has R and M t quite widely separate at origin, though divergent, 

 and the third segment of the palpus is rough, it would probably be better con- 

 sidered a Gnorimoschema or primitive Phthorimoea without pencil, but is usually 

 placed here. The pupa also is unlike other true Gelechias, though far from the 

 other Gnorimoschemas and Phthorimceas studied. 



34. G. arenella Forbes. Pale clay-color, the veins perceptibly paler, with some 

 scattered black scales; black discal dots and a dot in the fold; black terminal dots. 

 20 mm. 



May, June, and August. 



Massachusetts, on the coast. New York: Rockaway Beach. 

 The species is not close to Gelechia petasitis, of Europe, with which it has been 

 confused. 



35. G. branella Busck. Dull dirty ochreous, a little uneven; face paler; antennae 

 paler, annulate with black; palpi fuscous, the inner side and apex of second seg-
