LEPIDOPTERA OF NEW YORK AND NEIGHBORING STATES 435 



21. T. olivaceana Riley. Light lemon yellow, with a slight green tint, marked 

 with light chocolate brown, so overlaid with yellow as to appear gray; the markings 

 are largely longitudinal streaks, the principal ones being a broad one along lower side 

 of cell to middle of wing, one below basal third of costa, a narrow and clean- 

 cut oblique one from middle of costa to speculum, a small spot on inner margin 

 a quarter way out from base, and a large patch at anal angle; besides some small 

 streaks on costa and a vague dark shade through outer part of wing. Speculum 

 yellow, with some black dots. Fringe concolorous. 



June to August. 



New Hampshire to District of Columbia and Illinois. New York: Rhinebeck. 



22. T. vemiochrana Heinrich. Similar to T. olivaceana; palpus with a fuscous 

 spot on outer side of second joint. Fuscous bars on costa of fore wing distinct 

 from base to apex. 10-13 mm. 



August. 



Massachusetts ; New Jersey. 



23. T. tarandana Moschler. Light gray, powdered on a white base, with clear 

 white streaks, and with the pattern more or less denned with silvery white. Ante- 

 medial band strongly oblique outward from beyond basal angle to middle of cell; 

 light gray -brown, shaded with blackish on the fold; postmedial irregularly excurved 

 and widening toward inner margin, running from middle of costa to outer third of 

 inner margin, where it connects more or less distinctly with a similar narrow and 

 irregular terminal band, three fuscous spots on costa outwardly, denned by white 

 striae. Speculum enclosed by the irregular silver lines defining the postmedial 

 and terminal bands, filled with slightly yellowish white, mixed with gray, and 

 with a few black scales. Fringe white with a gray center line. Hind wing darker 

 gray. 25 mm. 



August.

16. 8PILONOTA Stephens 

 (Tmetocera, Lederer; Eucosma, in part, Walsingham and Durrant) 



Male without costal fold. Palpi beaklike, triangular, with third joint concealed 

 in scales. Thorax smooth. Fore wing practically smooth-scaled, with outer margin 

 concave at middle and M 3 and CUj somewhat approximated toward the margin. 

 Antennae with notch more widely open than in Strepsicrates and nearer base; the 

 segments concerned in it almost completely fused and difficult to count. 



Valve very long and narrow; cucullus with a large apical spine. Uncus absent; 

 socii short and broadish; gnathos weak. 



A development of Thiodia. 



1. S. ocellana Schiffermtiller. Dull grayish brown, somewhat mottled; the median 

 area typically contrasting dirty white, in variety lariciana Heinemami hardly paler. 

 Basal area with outer boundary roundly and moderately angled. Outer margin 

 shaded with gray-brown near apex; below, with about three black bars, followed 

 by a gray streak; a black spot before anal angle, made up of partly fused dots, 

 with a well-marked gray shade between it and the three black bars. Dark line in 

 base of fringe grayish and not contrasting. 12-15 mm. (pyrifoliana Clemens). 



Often injurious, the larva webbing together the opening buds of apple in early 

 spring. Moth in June to early August. 



General in distribution; also in Europe. Possibly introduced in this country.
