538 REPORT OF NEW JERSEY STATE MUSEUM. 



R. frustrana Scudd. Jamesburg; larvae bore into the terminal shoots of 

 pitch pine, dwarfing the vertical and lateral shoots (Kf ) ; Westville 

 IV (Kp); Riverton IV, Ocean Co. V (Sm); Lacy VII (Dke). 



R. wenzeli Kearf. Gloucester Co.; larvae winter in slender shoots of 

 "Pinus virginianus," the exudation of pitch forming a complete 

 cylinder around the stem; imagoes in early May (Kf). 



R. comstockiana Fern. Montclair, Anglesea, larvae winter in masses of 

 pitch on young branches of pine, moths VI (Kf ) ; Forked River Mts. 

 V, 27, Brown's Mills V, 30 (Dke). 



The "R. turionana" Hbn. is a European species which, it seems now, 

 does not occur in America at all. 



BACTRA Steph. 



B. furfurana Haw. 5-mile beach VII, 2 (Haim) ; has not been bred in 



America; in Europe the larva lives in stems of grasses, "Juncus" and 

 "Eleocharis." 



POLYCHROSIS Rag. (EUDEMIS Hbn.) 



P. viteana Clem. (botrana Schiff.) The "grape berry moth," which 

 sometimes causes trouble locally throughout New Jersey. It occurs 

 on my own grounds at New Brunswick, and I have seen it often in 

 other sections. There are three broods; the first in May, destroying 

 the entire clusters; the second late in July, boring into and webbing 

 up the half-grown berries; the third in late August, destroying the 

 nearly full-grown berries. Spraying with arsenate of lead to kill off 

 the first brood is indicated. 



P. slingerlandana Kearf. Essex Co. and doubtless all over the State 

 VII, VIII; larva in flower and seed heads of "Eupatorium perfoliatum." 



P. vernoniana Kearf. Caldwell VIII, larva on flower and seed heads of 

 "Vernonia noveboracensis," and probably abundant where its food 

 plant occurs (Kf). 



P. liriodendrana Kearf. Fairly abundant wherever the tulip tree is 

 found, July and September; larva in tents on under surface of leaves. 



P. magnoiiana Kearf. Moorestown, Lacy, and will be found wherever 

 the swamp magnolia occurs; larva under silken tents on underside of 

 leaves VII (Kf). 



CYMOLOMIA Led. (EXARTEMA Clem.) 



The larvas of these species are all leaf crumplers or tyers occurring in 

 May and June, the adults from mid June to mid July. There is only one 

 brood and the species are g. d., wherever the food plant occurs. 



C. exoleta Zell. Montclair (Kf ) ; New Brunswick; larva on gooseberry. 

 C. corylana Fern. Greenwood Lake VI (Kf ) ; larva on hazel.
