Phalonia oenotherana Riky. 



This gayly colored member of the Tortricidce was described by 

 Riley in 1881 (Tr. St. Louis Acad. Sci., IV, 316) from four speci- 

 mens bred from CEnothcra in Missouri by Miss Murtfeldt. Smith 

 (Ins. N. J.) lists it from Essex County, VII, 25 (Kf.), and Clemen- 

 ton, IV, 30 (Haim.), together with the statement, "larva on evening 

 primrose." In addition to these localities we have found it at Wood- 

 bury. Highland Park, Hackensack, Riverton, Monmouth Junction, 

 West End and Asbury Park. The larva lives in the tender, devel- 

 oping, leafy tip of the stalk, pulling the small leaves together more 

 or less. 



Egg. — Not observed. 



Full Grozvn Larva. — Length 6.8 mm. Width 1.7 mm. Light 

 tawny yellow, not elongate, comparatively broad; surface finely 

 shagreened; divisions between segments and transverse lines on 

 dorsal surfaces of segments usually strongly impressed; each body 

 segment bearing several, comparatively long hairs, with dark or light 

 tuberculate bases; head similar in color to body except spot around 

 which ocelli are clustered and apical portion which are darker (in 

 some specimens entire head is dark brown) ; thoracic and anal plates 

 brownish or light; each leg bearing several minute hairs. 



Pupa. — Length 5.5 mm. Width 1.6 mm. Elliptical, chestnut 

 brown. 



Adult. — Phalonia a-notlicrana. Tlie following is the original de- 

 scription by Riley: " ]\Iale and female. Expanse 9-10 mm. Basal 

 half of primaries yellow, apical half rose-red. Head gxay. Thorax 

 yellow, the patagia tipped with gray: primaries with the basal hall 

 yellow, the costa and apical half rose-red, the yellow extending as 

 a broad median emargination into the red ; the red portion more or 

 less dotted or fasciate witli black shining scales, these scales not 

 encroaching upon a central patch which contains a yellow spot of 

 variable size; some abbreviated black and white costal streaks; pos- 

 terior margin and fringes yellow, becoming gray at the anal angle ; 

 secondaries and under surfaces fuscous; legs silvery, the tibi;c and 

 tarsi mostly black or fuscous. Abdomen silvery-fuscous, paler be- 

 neath ; ovipositor laterally compressed." 



This species appears early in the season and evidently deposits 

 eggs on the developing terminal leaves or heads. The larva? cat out
